  • Andrew denies physical observations

    Hey Christophersj and BobFJ,

    Been following your exchange.  It appears to me that Andrew Dessler started the ball rolling with an unsubstantiated claim that "Negative climate feedback is as real as the Easter Bunny".

    This was all the more astounding, since it came after the physical observations by Spencer et al., which demonstrated a strong negative feedback from clouds, thereby in effect validating Lindzen's earlier "infrared iris" hypothesis.

    So it appears that Andrew's tactic was the classical one of a "denier".  When evidence is presented, which goes against the preconceived belief or paradigm, one simply sticks the head in the sand and denies that this evidence exists.

    Thomas Kuhn has written about this in his treatise on paradigms.  Physical evidence, which refutes the prevailing paradigm, is either ignored, refuted or (in some cases) not even seen.  This inability to think outside the box of the prevailing paradigm is, unfortunately, a frequently occurring problem with "mainstream consensus scientists", who have a vested interest in keeping the prevailing paradigm alive, and therefore defend it against any new data that may represent a direct challenge to the paradigm.

    I believe this is the crux of the problem here, although I have to admit that Andrew's choice of the "Easter Bunny" was cute.

  • amazingdrx returns!

    The amazinglyimperceptivedrx strikes again!

    To the topic of "meaningful contribution to the debate", amazingdrx conceded that he "never made one, never will".

    In going back through this and other sites to which the good "dr" has contributed, I can confirm that his statement is true.

    Why have a climate blogsite if every contributor is just going to repeat the officially sanctioned mantra without rationally and skeptically questioning the data that lie behind it?

    That's the whole purpose of these sites, to stimulate the ongoing scientific and political debate surrunding all the uncertainties relating to our planet's ever-changing climate. And, let's face it, there are many, as the exchanges demonstrate.

    Sure, there are some "trolls" out there who can only come with ad hominem attacks, snide remarks, emotional outbursts or toxic BS, but these are not to be taken too seriously.

    Stick with facts, amazingdrx, and you'll be better off.

    Just a tip.

    Regards,

  • Introduction of Peter Martin

    Christophersh

    Since Peter Martin has been kind enough to write his brief introduction of both Black Wallaby and myself, I'll return the favor, leaving out any opinionated comments.

    Peter Marting apparently lives in or near Brisbane.  He is a firm believer in the premise that anthropogenic greenhouse warming is causing and will cause great damage to our planet's environment.

    He bases his belief on a few points of data, such as the late 20th century increase in both global temperature and atmospheric CO2 and a recent trend of melting Arctic sea ice, but primarily on the firm belief in the notion that an "overwhelming majority" of scientists (a) support the suggestion of potentially disastrous AGW, and (b) that they cannot possibly be wrong in this assessment.

    He occasionally slips into discussions of a more political nature.  These reveal that he supports world socialism and big government intervention as solutions to many of the world's problems today. He has expressed his disdain for former UK PM Thatcher, for example.

    He favors massive international governmental mitigation actions to stop the AGW development before it is too late.

    He has been known occasionally to become emotional and lose his calm, but hardly ever does he slip into ad hominem attacks on those with whom he debates the issues. I can recall no incidents where he became openly hostile or impolite.

    I have never witnessed him telling his debate partners "you are insincere", accusing them of "extremely biased behavior" or calling them "frauds".

    His arguments are usually to the point, with only occasional side-tracks. As a result, he keeps his debate partners on their toes.

    So, all in all, he is an excellent partner with whom to debate the many unresolved scientific and policy issues surrounding AGW.

    You could learn from him, Christophersj, if you really want to make a meaningful contribution to the debate on sites such as this.

  • Nice dissertation Christophersj

    Very nice dissertation, Christophersj, although I completely missed the significance of your alleged "George Orwell government picture", which I apparently "have in my mind", or even less my lack of "criticism of right-wing unscientific foolishness", both of which you have apparently pulled out of the air (or possibly some other darker place) to divert from the real issues we have been discussing.

    What does all this silly double-talk have to do with a serious debate on the many unresolved scientific questions surrounding the ongoing debate on AGW?

    I'd say nothing.

    Christophersj, I'd recommend that you stay away from emotional polemic and stick to addressing the unresolved scientific questions surrounding the hypothesis of alarming or potentially disastrous AGW with an open mind.

    Forget references to "Orwell" or "right-wing unscientific foolishness".  These are emotional and polemic sidetracks that have absolutely nothing to do with the issue at hand.

    And while you are getting all your information on the topic at hand from Grist and Climate Progress, I'd suggest you also check out Climate Audit and What's Up With That to get a more balanced picture.

    Just a tip to help you become a bit more objective in this discussion.

    Regards,

  • Don't get emotional Christophersj

    Our discussion is apparently taking place on two different levels: emotional and rational.

    I personally prefer to address the scientific debate surrounding the AGW question rationally with a degree of rational skepticism.

    Yes, Christophersj, there is a valid ongoing scientific debate on this subject, i.e. the science on our planet's climate is not "settled", as some would have us believe.

    Despite your disclaimer, "What I AM is a rational and thinking human being - sans sociopathic paranoia" you appear to prefer the more emotional approach. Why else would you throw in the totally irrelevant "sans sociopathic paranoia" line? It really has nothing to do with our discussion.

    It also appears that you do not want to get into discussing any real substantive issues.

    Real science (as opposed to agenda driven pseudoscience) is based on rational skepticism, rather than "group think".

    Religious or quasi-religious belief is based on blind acceptance of a dogma, because the Bible (the IPCC, James E. Hansen, the prophets, Al Gore, the oracles, Susan Solomon, the "fortune teller", etc.) said so.

    When you make claims on substantive issues, I will challenge those claims if I can see that there is some evidence that they may be false.  And I will do this in a rational manner, not resorting to name calling or emotional outbursts.

    But if you just want to throw tantrums, count me out of the discussion.

  • Great side-step Christophersj

    Rather than addressing specifics, I see that you prefer to waltz around with side-steps and generalities.

    I could ask you the same silly question, "Which journals are your research and findings being submitted to?"

    You were probably spot on when you wrote, "I'm not qualified to say how or where your likely mistakes are.  I'm making a rational bet, a reasonable gamble, a sane reflection."

    Grow up and don't make silly claims you cannot substantiate.

    Just some advice.

  • Quick ocean check for Christophersj

    Christophersj

    You wrote: "And on ocean acidification, your just out-ranked on every point.  Coal can take us to enough emissions to matter.  Many phytoplankton require calcium building blocks and will crumble under acidification.  Its already started.  Please stop while you are digging yourself a hole."

    Let's do a quick check.

    The current carbon budget of the earth is not well known although there are estimates. What is the relation between the temperature at the air/water ocean interface and the rate at which carbon dioxide dissolves? What is the relation between the atmospheric CO2 concentration at the air/water ocean interface and the rate at which CO2 dissolves? What is the relation between the water temperature, the CO2 content of the water, and the rate of uptake of CO2 in cellular aquatic plant life? How much of the carbon uptake becomes waste (decay) and how much goes into skeletons (calcium carbonate)?

    Let's run through a quickie estimate.

    The ocean has a carbon sink estimated at 40,000 billion tons of carbon (GtC)

    The atmosphere currently has a carbon sink of 820 GtC (at 385 ppmv CO2 concentration)

    All the known and optimistically estimated fossil fuel reserves of our planet (coal, oil, gas) represent a carbon sink of 2,029 GtC.  That's all there is.

    Adding in another 15% for deforestation, cement production, etc. gets us to a total of 2,334 GtC

    If we consume all of this we will release 2,334 GtC (or 8,556 GtCO2 equivalent) into the atmosphere some far distant day in the future.

    Let's assume that the higher atmospheric CO2 levels will not result in a higher level of photosynthesis over land (as studies have shown).

    Currently between 50 and 60% stays in the atmosphere and the rest is absorbed by the ocean on a net basis. Let's assume it will be 60% in the future, as well.

    This means that we will increase the atmospheric carbon by from today's 385 ppmv to an absolute maximum value of 1,042 ppmv when all the world's fossil fuels are gone.

    From 1850 to 2008 we had 0.65C warming, of which 0.35C is attributable to the unusually high level of 20th century solar activity (see earlier post).

    This leaves 0.3C warming from all other causes; let's assume this was all due to increased atmospheric CO2.

    Using the logarithmic relationship we arrive at additional warming expected from consuming all the fossil fuels on our planet of an additional 1.0C:

    ln (385/285) = 0.3008
    ln (1042/385) = 0.9958

    dT = 0.3 * (0.9958 / 0.3008) = 1.0C

    The ocean will absorb the remaining 40% or 3,423 GtCO2 = 923 GtC
    The ocean sink will increase from 40,000 GtC to 40,923 GtC or by around 2%

    Now to "ocean acidification".  This is a misnomer.  Wikipedia tells us that the surface ocean pH has decreased from 8.179 to 8.104 (i.e. the ocean has become slightly less alkaline) from pre-industrial times to today.  Wiki cites a study showing that this could decrease to around pH 7.949 when atmospheric CO2 levels reach 560 ppmv and pH 7.824 based on IPCC IS92s scenario (atmospheric CO2 = 1,100 ppmv).

    As far as the impact of slightly higher CO2 levels on oceanic calcifying organisms is concerned, Wiki cites conflicting studies: some state that this could result in reduced calcification, others show both photosynthesis and calcification increasing. Recent studies examining North Atlantic sediment cores found that calcification of coccoliths increased by 40% since 1740.

    As far as other consequences of a slightly less alkaline ocean are concerned, Wiki states, "However, as with calcification, as yet there is not a full understanding of these processes in marine organisms or ecosystems."

    Wiki concludes with the statement:
    "Leaving aside direct biological effects, it is expected that ocean acidification in the future will lead to a significant decrease in the burial of carbonate sediments for several centuries, and even the dissolution of existing carbonate sediments. This will cause an elevation of ocean alkalinity, leading to the enhancement of the ocean as a reservoir for CO2 with moderate (and potentially beneficial) implications for climate change as more CO2 leaves the atmosphere for the ocean."

    I've read several studies on this topic as well, but Wiki gives a pretty good summary.

    So you see that there is no conclusive evidence that the slight decrease in upper ocean alkalinity will have any harmful effects, as you postulated.

    Hope this helps clear up this point.

  • Pick the "just right" temperature

    Christophersj,

    You wrote:  "There is also no "just right" temperature for our planet."  Yeah, except when you need to feed and water 8 billion people."

    Is this supposed to be a riddle?

    What is the "just right" temperature for our planet (in your opinion)?

    First, let's define "temperature" as the "globally and annually averaged land and sea surface temperature anomaly" (as reported by Hadley) plus Hadleys' 1961-1990 "baseline" of 15.0C.  OK?

    Is the "just right" temperature the one we had the past year (2008) = 15.312C?

    Is it the slightly higher temperature we had in 1998, the record hot year of the 20th century = 15.515C?

    Is it the slightly cooler temperature we had in 1976 = 14.771C?

    How about the temperature in 1944 (a teeny bit warmer than 1976) = 15.087C?

    Or maybe the slightly cooler temperature we had in 1910 = 14.441C?

    Is it the temperature we had in 1850, as we were just coming out of the Little Ice Age = 14.598C?

    Or do you prefer the even cooler LIA temperature of 1700 = around 14.0C?

    Or maybe the temperature of the Medieval Warm Period, around 1000AD, a bit warmer than the one of 1998 = around 16.0C?

    Take your pick. Let me know which of the above is "just right" (if you have another pick not listed above, please let me know your choice).  Thanks!

    Regards,

    Max

    PS BTW the colder temperature of the LIA resulted in crop failures, food shortages and famines with a world population of around 1 billion, so if feeding 8 billion is your concern, I'd go for the warmer side rather than cooler.On Australia faces collapse as climate change kicks in posted 9 months, 3 weeks ago 50 Responses

  • Let's clear up Christophersj

    Hey Christophersj,

    I just answered your "relatively stable climate conditions" post above.

    Now let's quickly go through your last rant.

    You wrote, "To say, "Climate is continuously changing on a global basis, as it always has and is today." is, by its very nature, a slippery statement meant to diffuse talks of action.

    Not at all, Christophersj.  It is simply a statement of fact.  That's all.

    Then you added, "Your second answer has a wrong mathematical error somewhere in it.  I dont know what you have left out of your equation.  I'm not a climate scientist."

    Nor am I, but I can understand the studies that are out there that tell me the sun caused around half of the observed warming to date, leaving the other half for all other factors (including CO2).  IPCC tells us that their "level of scientific understanding" of "solar forcing" is "low", so I have to accept the many studies out there by solar experts who have a higher "level of scientific understanding" on solar impacts than IPCC.

    This means that the warming we can expect from a 2xCO2 scenario (as expected by year 2100) is around 0.7C.  We have seen 0.3C to date, leaving 0.4C from now to year 2100.

    It's actually quite simple.

    Your next statement that "ocean acidification is NOT complex.  It is 100% provable and attributed to humans" is a bit doubtful.  The ocean is basic (not acidic).  It contains gigantic masses of CO2 absorbing phytoplankton.  The carbon balance of the ocean is extremely complex, and its "carbon sink" is vast.  Humans are not going to do much "damage" here with the limited overall supply of fossil fuels on our planet, regardless of alarmist predictions by some so-called "climate scientists".  Go through the numbers yourself, and you'll see that this is not a problem.

    Whether "the community of countries WILL sign in December in Copenhagen" or not is immaterial.  No matter what the politicians of the "community of countries" decide to do, it will not have any impact on our planet's climate. Zilch.

    Your last outburst of "keeping the bloggers honest" and "right-winger's silliness" was so off the wall that it does not merit a response.  

    As I advised you earlier: "Don't throw a tantrum and make childish statements.  Makes you look silly.  Stick to the facts instead."

  • My wish for Christophersj...

    Hi Christophersj,

    You wrote, "MY motivation... is to ensure the same relatively stable climate conditions that allowed for the agricultural revolution in 10,000 BC up to the 20th Century.  Hopefully until the next ice age begins -- is my wishful thinking."

    Good plan.  But there is a bit of a problem.  Climate has changed considerably over the past 12,000 years, without the impact of any human CO2 emissions.  There were no "relatively stable climate conditions" over this period, as everyone (except Michael Mann) knows.  In fact, there were several swings that overshadow the current warming "blip" in the record.

    There is also no "just right" temperature for our planet.

    So we will have to live with whatever climate swings nature deals us.

    Let's hope these do not include an imminent return to Little Ice Age conditions.  The last one was catastrophic for around 1 billion humans in the late 18th century but a repeat today could really be disastrous for a world of almost 7 billion people.

    So my "wishful thinking" is that natural factors do not cause a major cooling cycle for our planet.

  • Response to Chistophersj

    Christophersj  posed a question (5 Feb) to Black Wallaby and me:

    "In this thread you are intending to give the impression that no general global climate change is happening at all.  And yet in other instances you concede the warming, but that its not the fault of AGW, but the sun or whatever your flavor is that week.
    Which is it?  You cant hold both points of view.  You're just being contrarian for its own sake and jumping into different logic pools when it suits you.  Its like some kind of psychological addiction."

    Can't speak for Black Wallaby, but here is my response (just to straighten out your obvious confusion).

    Your first statement "In this thread you are intending to give the impression that no general global climate change is happening at all" is incorrect and unfounded.

    Climate is continuously changing on a global basis, as it always has and is today.

    To your next point, "in other instances you concede the warming, but that its not the fault of AGW, but the sun or whatever your flavor is that week".

    The long-term Hadley record shows 0.65C warming from 1850 through 2008.

    Several stusies by solar scientists tell us that the unusually high level of 20th century solar activity (highest in 11,000 years!) has been responsible for around 0.35C of this total long-term warming.

    This leaves 0.3C for anthropogenic warming (or UHI distortion, effect of PDO, ENSO, NAO oscillations, etc.).

    Let's assume it was ALL due to AGW.

    Using this warming plus the atmospheric CO2 levels as published by IPCC for 1850 and Mauna Loa for 2008, we arrive at a 2xCO2 climate sensitivity of around 0.7C.

    Extrapolating this to the projected 2100 CO2 level, gives us an additional anthropogenic warming of 0.4C from today to year 2100.

    Got it?

    Then you wrote, "You can't hold both points of view".

    As you have just seen, I do not "hold both points of view".

    Finally you added, "You're just being contrarian for its own sake and jumping into different logic pools when it suits you.  Its like some kind of psychological addiction."

    Aw c'mon.  Don't throw a tantrum and make childish statements.  Makes you look silly.  Stick to the facts instead.

  • Is amazingdrx confused?

    Wow!

    amazingdrx is explaining to us how anthropogenic global warming is going to cause "dust storms on a global scale [that] trigger volcanic like cooling as happened in 1816, when three volcanoes triggered drastic cooling and a year without a summer".

    Hmmm...

    Please explain your hypothesis here (anthropogenic warming causes disastrous cooling); amazingdrx, it sounds a bit convoluted.

    In fact, it sounds downright confused.

  • Call off the canaries, Joe

    Good ol' Joe Romm (bless his confused heart) warns us "Australia is the canary in the coal mine for climate-driven desertification".

    A "global Dust Bowl" is imminent.

    Hmmm. Didn't the term "Dust Bowl" originate in the distant pre-AGW 1930s?

    But wait a minute!

    I've heard this "canary" line before.

    Last time it was that the "rapid melting of Arctic sea ice" was the "canary in the coal mine for climate-driven sea level rise". (Or possibly some other horrible future disaster).

    Call off the canaries, Joe.  It's all BS.

  • Note to EliRabett

    As Black Wallaby pointed out, life would be so much easier if one could make things go away by just denying them or saying "they are as real as the Easter Bunny".

    Unfortunately for the negative feedback deniers (like Andrew), it doesn't work out that way in real life.

  • It's the long term trend, stupid (314159265).

    "It's the long term trend, stupid."

    Sure is.

    Not the "last twenty-four years of the 20th century" (which have been used by IPCC to "prove" AGW).

    The long term trend, stupid, starts with the Hadley record in 1850 and ends with December 2008.

    This long term trend shows a linear warming of 0.65 over the entire period, stupid.

    Solar scientists have told us (in many studies) that the unusually high level of 20th century solar activity was responsible for around 0.35C (average value of several studies).

    This leaves 0.3C for all other causes, including UHI, high level of late 20th century ENSO activity, plus anthropogenic warming (primarily from CO2). Can you follow the arithmetic here?

    Let's assume this was ALL due to anthropogenic forcing.

    Using the atmospheric CO2 levels assumed by IPCC for 1850 and those measured at Mauna Loa for 2008, we arrive at a 2xCO2 climate sensitivity of around 0.6 to 0.8. This arithmetic is a bit more daunting, but I'll be glad to walk you through it if you're having trouble following.

    If we now project that atmospheric CO2 levels will reach twice the 1850 level by year 2100, we can project another 0.4C warming from today until then.

    This is what the long-term trend tells us, STUPID.

  • A graph for 314159265

    To make it a bit easier for 314159265 to visualize Ian Jolliffe's statement, here is a graph.
    http://farm4.static.flickr.com/3383/3233586332_484745b123 ...

    Jolliffe's "very unlikely" forecast of a complete reversal of 1951-2000 warming by year 2030 is shown as the blue line.

    The purple line is a projection based on the continuation of the actual 2001-2008 cooling trend to year 2030. Some solar scientists prefer this projection, but it is probably also unlikely.

    The orange line is a somewhat questionable projection by IPCC, whereby the 2001-2008 cooling trend reverses itself drastically from 2008 to 2030 due to AGW.

    The red line is an even more unlikely projection by Hadley, whereby the 2001-2008 cooling trend reverses itself even more sharply from 2008 to 2030.

    The black dashed line is probably the most likely projection (in my opinion), based on a continuation of the trend from 1951-2000 to year 2030.

    But which projection is the right one?

    Who knows?  Probably neither IPCC nor Hadley. Probably not Andrew Dessler. Certainly not Tamino or me.  

    Only time will tell.

  • Ian Jolliffe makes good sense, but...

    Ian Jolliffe makes sense, but...

    The Ian Jolliffe quote cited by 314159265 makes sense: "the chance of all the climate models having got things completely wrong and that by 2030 the Earth is cooler than in 1950 is of the same order of magnitude as the chance that the USA will decide that independence was a bad idea and ask to be taken back as a British colony by the same date. Not impossible, but I personally wouldn't bet on it."

    The warming our planet has experienced over the second half of the 20th century is real even if there may have been some distortions to the temperature record due to the UHI effect.

    But let's look more closely at the warming over the second half of the 20th century (1951-2000).

    In 1951 the Hadley temperature anomaly was -0.172C.
    In 2000 it was +0.238, for a net delta of 0.41C.

    The linear rate of warming was 0.0988C per decade or 0.49C over the 50-year period.

    The question is not whether or not whether the Earth will be cooler in 2030 than in 1950, i.e. that 50 years of warming from 1951 to 2000 will be reversed by 30 years of even more rapid cooling from 2001 to 2030.  This is obviously extremely unlikely to occur, as Ian Jolliffe has correctly suggested.

    The real question is whether or not the climate model forecasts made by IPCC and Hadley for accelerated warming over the first decades of the 21st century will truly occur.  These forecasts are 0.2C per decade and 0.3C per decade warming, respectively, i.e. two to three times the actually observed warming rate from 1951 to 2000.

    The Hadley temperature anomaly in 2001 was 0.40C.  

    This means that IPCC projects a 2030 temperature anomaly of 0.4 + 3 * 0.2 = 1.0C.

    Hadley goes even further to predict 0.4C + 3 * 0.3 = 1.3C.

    The first eight full years of the 21st century (2001-2008) have shown a net cooling rate of -0.111C per decade, rather than accelerated warming, as projected by IPCC and Hadley. The anomaly in 2008 was +0.31C, compared to +0.40C in 2001, for a net cooling of almost 0.1C over the period.

    I'd say the "jury is very much out" on whether the warming will occur as projected by the IPCC and Hadley climate models.  I would even conclude that this is highly unlikely.

    To quote Ian Jolliffe, "Not impossible, but I personally wouldn't bet on it."

  • 314159265 is confused

    Sorry 314159265, sounds like you are a bit confused.  Tamino's so-called "debunking of Spencer" is full of glaring errors and omissions.

    "Warmer air holds more water vapor" is basically a correct statement, but it should be reworded, more accurately, to "warmer air can hold more water vapor".  IPCC assumes that is does so to maintain constant relative humidity.  Physical observations have shown that this assumption is incorrect and that the IPCC assumptions on positive feedback from water vapor are therefore exaggerated.

    "As earth warms there's less ice and snow covering the planet" (leading to a positive surface albedo feedback).  Great theory, but it just hasn't worked out that way in real life.  After a year of low snow cover in 2007 (not quite as low as it was throughout most of the 1980s and 1990s, however) December 2008 Northern Hemisphere snow cover is back above the 1978-2008 average. The December linear trend since 1978 has been an increase of 0.838 million sq.km. (around 2%) per decade..
    http://climate.rutgers.edu/snowcover/chart_vis.php?ui_yea ...

    Arctic sea ice extent has receded (with lots of media hype); Antarctic sea ice extent has grown (with no media coverage).  The latest data from NSIDC show that the global extent is about the same today (December 2008) as it was over the 1979-2000 mean baseline:
    December 2008
    12.53 sq. km. (Arctic)
    12.20 sq. km. (Antarctic)
    24.73 sq. km. (Total)

    1979-2000 mean

    According to IPCC, "lapse rate" feedback is negative, reducing the impact of the closely related positive water vapor feedback, not a positive feedback, as falsely assumed by Tamino.

    But Tamino's biggest error is that he does not discuss the observed strongly negative feedback from clouds.  This physically observed negative feedback is so strong that it, in effect, cancels out all the other assumed positive feedbacks combined.  Instead of contributing +1.3C to the 2xCO2 climate sensitivity as assumed by IPCC, the physically observed feedback from clouds represents a cooling impact of around -1.5C.  This puts the total 2xCO2 climate sensitivity at around 0.6 to 0.8C, rather than the 3.2C assumed by the IPCC climate models.

    Forget Tamino's debunk of Spencer.  It's junk science and hype at its best.

    The physical observations of Spencer et al. on cloud feedbacks have shown that the net overall cloud feedback is strongly negative, rather than strongly positive, as assumed by all the IPCC climate models. And Tamino has not been able to "debunk" this.

  • Some practical background for Andrew Dessler

    The "cloud feedback" story has an interesting background, as I'm sure Andrew will agree.

    There have always been conflicting hypotheses as to the real impact of clouds on AGW.  While it is clear that the net overall impact of clouds on our climate is one of significant cooling (several times the assumed greenhouse warming impact from CO2), it has been unclear what would happen to clouds with increased surface warming caused by AGW.

    High altitude ice-crystal clouds allow incoming SW radiation to pass through but effectively trap reflected outgoing LW radiation, thereby leading to warming.

    Lower altitude liquid droplet clouds reflect incoming SW radiation, thereby leading to cooling.

    A study by Lindzen suggested that the net effect of higher surface temperatures would be to reduce the formation of (warming) high altitude ice-crystal clouds, thereby providing a net negative feedback.  Lindzen called this postulated (but unproven) effect "the infrared iris".

    In a study on the radiative forcing of water vapor and clouds, Ramanathan stated:
    "The few results we have on the role of cloud feedback in climate change is mostly from GCMs.  Their treatment of clouds is so rudimentary that we need an observational basis to check the model conclusions.  We do not know how the net forcing of -18W/m^2 will change in response to global warming.  Thus, the magnitude as well as the sign of the cloud feedback is uncertain."

    The climate models cited by IPCC all assumed a strongly positive (warming) net feedback from clouds (resulting in 1.3°C of the assumed total 2xCO2 climate sensitivity of 3.2°C), although IPCC conceded in its 2007 SPM report "Cloud feedbacks remain the largest source of uncertainty."

    So it should have come as a great relief to all in the scientific community when this "largest source of uncertainty" was cleared up by the physical observations of Spencer et al., providing "an observational basis to check the model conclusions", as Ramanathan had lamented was lacking earlier.

    And not only that!  The physical observations of Spencer et al. demonstrated that the net feedback from clouds with warming is a strongly negative feedback, not only canceling out the IPCC-assumed +1.3°C warming effect from clouds, but resulting in an even larger cooling effect, so that the 2xCO2 climate sensitivity would now be an innocuous 0.6 to 0.8°C, rather than the alarming 3.2°C, as estimated by the GCMs cited by IPCC.

    Rejoice!  The end is not near!

    But instead of sighs of relief, we heard howls of indignation and anguish by the "climate science community".  How could Spencer publish something that shoots down the very notion of alarming AGW?  How could the physically observed facts be so different from the hypothesis?  What was wrong with Spencer's observations, which had to be incorrect as they conflicted with the theory, which had to be right.

    And finally (the most ridiculous and transparent reaction of all): let's ignore (or deny) the physical observations and make a flat statement (based on paleoclimate data [?!] and other gobbledygook) that negative feedbacks are as real as the "Easter Bunny".

    Sorry, Andrew.  In the court of common sense, you LOSE.

  • Note to Black Wallaby

    Hi BW

    You wrote: "there are a couple of things in Spencer's paper that make me wonder how "global" the negative 6.1 W/m^2°C [forcing] is".

    It's true that Spencer's observations only covered the tropics from -20 to +20 degrees latitude.

    This region comprises around 40% of the earth's surface area and receives well over half of the total insolation.

    The crux of the matter is that IPCC AR4 WG1 Chapter 8 (p.630) lists an assumed multi-model mean forcing for clouds as +0.69±0.38 W/m^2°C.

    On p.633 IPCC informs us that this forcing from clouds would result in an increase of the 2xCO2 climate sensitivity of +1.3°C (from + 1.9°C without clouds to +3.2°C with clouds).

    So if Spencer's negative forcing from clouds is globally only half (or even one-fourth) the -6.1 W/m^2°C observed over the study area, this still represents a major negative feedback from clouds, that would essentially cancel out the net positive feedbacks from water vapor less lapse rate plus surface albedo, as listed by IPCC.

    It is the physically observed "major negative feedback" that Andrew Dessler relegates to the "Easter Bunny".

  • Note to Black Wallaby on cloud radiative forcing

    Hi BW,

    In your 22 January post to Andrew Dessler, you wrote, "In your latest work on water vapour with Zhang and Yang you show a positive ~2 W/m^2, but I seem to recall Spencer suggests higher negative values than that somewhere.

    Yeah. That is correct.  Actually much higher.  Check the Spencer study on physically observed cloud feedback:
    http://blog.acton.org/uploads/Spencer_07GRL.pdf

    "Our measured sensitivity of total (SW + LW) cloud radiative forcing to tropospheric temperature is -6.1 W/m^2K".

    The IPCC estimates on 2xCO2 climate sensitivity of 3.2°C includes net positive feedbacks from both water vapor and clouds, as well as a negative feedback from lapse rate and a positive feedback from surface albedo.

    In its AR4 WG1 Chapter 8 report (p.630) IPCC states that the multi-model mean forcing and standard deviation for each in W/m^2 °C is:
    Water vapor +1.80 ±0.18
    Lapse rate -0.84 ±0.26
    Albedo +0.26 ± 0.08
    Clouds +0.69 ± 0.38

    Using these feedback parameters, the 2xCO2 feedback temperature response would be:
    +0.8°C [2xCO2] (p.758)
    +1.5°C [Water Vapor]
    -0.8°C [Lapse Rate]
    +1.5°C [Sub-total 1] (p.631)
    +0.4°C [Albedo]
    +1.9°C [Sub-total 2] (p.633)
    +1.3°C [Clouds]
    +3.2°C [Total, all feedbacks] (p.633)

    If we now correct the IPCC assumed strongly positive net feedback from clouds with the physically observed strongly negative feedback as demonstrated by Spencer et al., (and even if we add in the slightly higher latest Dessler et al. estimate for water vapor), this will result in a total net 2xCO2 climate sensitivity of around 0.6 to 0.8°C, rather than the IPCC assumed value of 3.2°C.

    Hope this helps.

    Spencer is a respected and renowned climate scientist.

    The "strongly positive" cloud feed back as assumed by all the climate models cited by IPCC (leading to 1.3C of the 3.2C warming assumed by IPCC for 2xCO2) has been effectively refuted by the study of Spencer et al., which showed that the cloud feedback on warming is strongly negative instead.

    The Spencer et al.study was also validated by a totally independent study by Norris, also showing a strongly negative feedback from clouds.

    Aw c'mon Andrew.

    Or the independent study by Norris, showing essentially the same.

  • On air we breathe for Pompey Road

    Coming back to what you wrote: "Even if the co2 effect on global warming or weather turns out to be insignificant every other effect of higher co2 levels need to be explored. Black lung is a major problem in the coalfields we could use a little extra oxygen."

    Checking "black lung disease" on the internet I read, "Black lung disease is the common name for coal workers' pneumoconiosis (CWP) or anthracosis, a lung disease of older workers in the coal industry, caused by inhalation, over many years, of small amounts of coal dust."

    So it's coal dust, not CO2 that causes this disease.

    To your statement that "we could use a little extra oxygen", I'd say we may not need a "little extra", but we surely don't want "a whole lot less" oxygen.

    Wikipedia tells us that.our atmosphere has 20.95% by volume oxygen and 0.038% by volume CO2.

    If we were to completely burn all the fossil fuel reserves of our planet, and all of the CO2 generated would stay in the atmosphere, this is estimated to cause an increase in atmospheric CO2 concentration to 1100 ppm (or 0.11 vol %).

    OSHA tells us that 5000 ppm CO2 is the threshold value for occupational safety, so we would be well below that value.

    OSHA also tells us we need a minimum of 12% oxygen (people with medical conditions may even need 15%) to avoid problems (headaches, loss of concentration, etc.)

    Each mol of CO2 generated consumes a mol of oxygen, so the oxygen content of our atmosphere would be reduced from
    20.95% today, to
    20.95 - 0.11 + 0.038 =
    20.88% some day in the far distant future, when all fossil fuel reserves are used up.

    I do not believe that anyone would notice this minor change, do you?

    Excluding the potential impact on our planet's climate I think we can safely rule out human CO2 emissions as a threat to human health.

  • Note to Pompey Road

    I agree that atmospheric pollution, from particulates or whatever unnatural and toxic component, is a bad thing and should be stopped.

    CO2 is not pollution.

    CO2 is a colorless, odorless naturally occurring trace gas in our atmosphere, which is essential to all life on our planet.

    Every time you exhale you are adding CO2 to the atmosphere. The same is true for all animals.

    CO2 has no harmful effect whatsoever on human (or other animal) life at the concentrations we see today or can imaging in the future.

    If ALL the fossil fuels of our planet (yes, including all the coal) were to be burned and all the CO2 generated were to remain in the atmosphere, the atmospheric concentration of CO2 could reach a hypothetical level of around 1100 ppmv, or around 4x the level assumed for "pre-industrial times" of 280 ppmv.

    At this level the greenhouse theory tells us we would see another 1C warming above today's temperature. This is supported by the actual warming from CO2 we have experienced from 1850 to today (around 0.3C).

    Let's concentrate on REAL pollution problems out there (there certainly are plenty, not to even mention cigarette smoke) and forget this hypothetical problem created by the virtual world of computer models.

  • Suggestion to Bob Wallace

    Bob

    If you want to sound like you have a clue in this discussion, it would be better to drop silly statements such as those you just made, and bring some facts (that is, if you have any).

    Antarctica is not warming up. In fact, the record shows that it has been cooling slightly for quite a while.

    On balance, the Antarctica Ice Sheet does not appear to be losing mass, based on long-term studies published in 2006.

    If you have results from a more recent long-term study showing a net mass loss, please cite the reference.

    Antarctic sea ice has also been expanding.  This gets much less media attention than the offsetting net contraction of Arctic sea ice, but it is happening just the same.

    Bring facts, Bob, and you'll be taken more seriously.

  • Relax Robco1, it's OK...

    You seem to be concerned about Antarctica.  You should really calm down.

    A September 2007 report states that according the NASA GISS data, the South Pole winter (June/July/August) cooled about 1 degree F since 1957 and the coldest year was 2004.
    http://icecap.us/index.php/go/joes-blog/a_new_record_for_ ...

    A recent report shows data that support the conclusion that the slight long-term cooling trend has continued through 2008.
    http://digitaldiatribes.wordpress.com/2008/11/30/2008-upd ...

    The mean summer temperature is -15 to -35C
    The mean winter temperature is -40 to -70C
    Not much ice melts at these temperatures
    http://www.antarcticconnection.com/antarctic/weather/inde ...

    As far as the threat of melting Antarctic ice is concerned, a long-term study published in 2006 (based on 10+ years of satellite measurements) has shown that the Antarctic Ice Sheet grew on average over that period.
    http://journals.royalsociety.org/content/38315t2244r5w3m4 ...

    A quote from this study: "Mass gains from accumulating snow, particularly on the Antarctic Peninsula and within East Antarctica, exceed the ice dynamic mass loss from West Antarctica." A net mass growth of 27 Gt/year is reported.

    The relatively small Arctic Peninsula (0.8% of Antarctic ice sheet) has warmed, but ice mass has grown, due to increased snowfall, which exceeded the loss of glacial ice to the ocean.

    The West Antarctic Ice Sheet (10.0%) appears to have receded, not due to melting, but due to the net flow of ice to the ocean from ice streams and glaciers, exceeding the mass gain from snowfall; this has apparently occurred even though temperatures have remained stable.

    The much larger East Antarctic Ice Sheet (89.2%) has cooled and is growing, due to increased snowfall.

    IPCC states, "Current global model studies project that the Antarctic Ice Sheet will remain too cold for widespread surface melting and is expected to gain in mass due to increased snowfall."

    Forget all the hype about 6-meter inundations caused by imminent melting or collapsing of the Antarctic ice sheet.  It's just science fiction and hype.

    I also agree that CO2 sequestering is a monumental boongoggle that presents more potential problems than solutions.  Let the CO2 go into the atmosphere, where it is a natural and harmless constituent, rather than pumping it into underground formations with unknown consequences.

  • Response to Bob Wallace's last two rambles...

    Bob

    Your last two posts "bobbles and bits" plus "and a bit more" rambled a bit, so I'll try to cover the points one by one as concisely as possible.

    Yes, the total sea ice trend (Arctic plus Antarctic) does appear to be fairly constant, as I wrote.  The Arctic is shrinking (as your NOAA report confirms) and the Antarctic is growing. Both recede in summer and grow back in winter.  As one grows, the other shrinks, and together they represent some 21 to 26 million square km over the year.

    The latest posted record (December 2008) shows no global change compared to the 1979-2000 baselines.

    Don't mix discussions on floating sea ice (no impact on sea levels) with those of the Antarctic ice sheet.  The last long-term study showed this has grown slightly on average from 1993 to 2003. I would stay away from "what if" future sea level projections of what might happen if it all melted.  IPCC tells us "current global model studies project that the Antarctic Ice Sheet will remain too cold for widespread surface melting and is expected to gain in mass due to increased snowfall".

    Ozone hole?  Get serious. We are talking about changing our planet's climate.

    "Max ignores the principle of `too much of a good thing'."  How much atmospheric CO2  is "too much" for whom, Bob?  On what do you base this suggestion?  Forget the flawed "room full of CO2" analogy or any Hansen 450 ppmv "tipping point" hype. Come with some facts or drop the subject.

    You wrote: "I invite Max to not experiment with the rest of us by increasing our greenhouse gases blanket.  We're warm enough now, thank you."  

    Who is "experimenting" with whom, Bob?  Who is "the rest of us"?  Who is "warm enough now"?  What is this silly sentence really supposed to mean?

    You seem to be of the "Goldilocks" opinion that our "globally and annually averaged" climate is "just right", and that any change would make it no longer "just right".  

    Tell me, is it "just right" today (January 2009) or was it "just right" before human greenhouse gas emissions started in the late 18th century?

    Did the 0.3C greenhouse warming we have seen from 1850 to the present help make it "just right" today? Or did it cause it to get 0.3C warmer than "just right"?

    Will it be less "just right" in year 2100 if it warms another 0.4C on average from today? How do you define "just right"?

    I'd suggest that it would be wiser for you to limit your discussion to facts and figures and not get caught up in a bunch of irrelevant side remarks.

    Yes, I have lived in China as well (not in Beijing, but in the south), and it is true that the air in most cities there is pretty hard to breathe, especially for those who suffer from asthma.

    This is not due to CO2, of course, but a result of the air pollutants from the coal they burn.

    I agree that it should be a priority to clean up any dirty coal power plants anywhere in the world, but, of course, this has nothing to do with CO2, a non-polluting natural component of our atmosphere essential to all life on our planet.

    You state: "We desperately need to know now what effect the co2 we have already added to the atmosphere has had and what will be the effect of stopping the man made co2 will have in real time."

    I believe we do have a fair indication.

    Temperature observations over the past 150 years of the Hadley record (as flawed as these may be due to all sorts of distortions, etc.) tell us that our planet has warmed by around 0.65C over this period.

    Solar scientists tell us that the sun was responsible for around half of this (0.35C), leaving the other half (0.3C) to anthropogenic causes, other (unknown) natural causes or measurement artifacts and errors.

    If we assume that all of the 0.3C was caused by anthropogenic factors (primarily CO2, which rose from 280 to 385 ppmv over the period) we see that a further increase of CO2 to 560 ppmv (as projected for the year 2100) will result in an additional increase of 0.4C.

    This is nothing to worry about and will certainly not "doom life as we know it".

    It appears that the unusually high 20th century level of solar activity has slowed down with solar cycle 24.

    The unusually active warming El Nino cycles of the late 20th century have also reversed to cooling La Nina cycles.  

    At the same time we observe that global average temperature has cooled since around 2001.

    All this despite all-time record breaking human CO2 emissions.

    Sea levels are, in fact, not rising any more rapidly than they did in the early 20th century.

    The total sea ice trend (Arctic plus Antarctic) appears to remain fairly constant, with major seasonal swings, as always.

    We are not the "drivers" of climate, regardless of all the hype out there.

    It is an illusion to think that there is anything we can physically do to significantly change our climate, either today or over the next century.

    Well, yes, it does appear that you did miss my point.

    But let's first apply the "hype filter" on your post (thawing permafrost, reduced snow/ice cover, saving the planet for future generations, etc.) and get back on the topic.

    [We can discuss all these other points separately.]

    The Hadley temperature record tells us that we have seen a linear warming rate of 0.041C per decade from 1850, when the record started, to 2008.  This represents a linear warming of 0.65C over the entire period.

    The solar studies indicate that the unusually high level of solar activity contributed 0.35C to this warming, leaving 0.3C for anthropogenic causes (or other, as yet unidentified factors).

    Atmospheric CO2 rose from around 280 to 385 ppmv over this period.

    From this we can project the warming we can theoretically expect from today until year 2100, assuming that CO2 levels double from the pre-industrial level to 560 ppmv.

    This calculated warming turns out to be 0.4C.

    You wrote, " A 0.35C change we can live with.  A 6.0C increase will be and end of life as we live it."

    It appears that the change of 0.4C we can expect (based on the theoretical anthropogenic warming) is a "change we can live with".  There is no logical reason to assume that this change will be 15 times the theoretical level from greenhouse warming, as observed over the past 150 years.

    That was my point.

    Read all of the studies I cited (rather than "cherry-picking" one quote from one study), and you will indeed see that they conclude on average that increased 20th century solar activity (the highest in several thousand years) resulted in 0.35C warming.

    This is not 100% of the observed warming (0.65C from 1850 to 2008 according to Hadley), but it represents a bit more than half over the entire period.

    Most of the studies also conclude (as did Georgieva et al.) that other factors (anthropogenic, for example) may have caused a significant portion of the warming observed in  "the last decades" of the 20th century.

  • Strong negative feedback

    JR should really get "up to date". "Science" is a "moving target" and new data are reported daily.

    Back in February 2007 (almost two years ago now), IPCC released its 2007 SPM report, followed by the AR4 report. These were based on data from 2006 and earlier.

    Cloud feedbacks were assumed (in all the climate models) to be strongly positive, contributing 1.3C to the 2xCO2 climate sensitivity assumed to be 3.2C.  IPCC did concede at the time that "cloud feedbacks remain the largest source of uncertainty".

    There had been studies expressing doubt on cloud feedbacks, such as the one by Ramanathan et al. that stated "the magnitude as well as the sign of the cloud feedback is uncertain".

    Two independent studies (Spencer et al., Norris)based on actual physical observations (rather than hypothetical model assumptions) helped to clear up this "large source of uncertainty" in showing that the net feedback from clouds is strongly negative, with a 2xCO2 impact of around -1.0C (rather than a positive feedback, resulting in an impact of +1.3C as assumed by all the IPCC climate models).

    Another study on water vapor feedback (Minschwaner + Dessler) shows, again based on actual physical observations, that the IPCC model assumption of "constant relative humidity with warming" is false, and that the positive water vapor feedback as assumed by the IPCC climate models is overstated by at least 0.3C.

    Together these two corrections to the 2xCO2 climate sensitivity of 3.2C, as assumed by the IPCC climate models, result in a corrected number of 0.6C, based on actual physical observations.

    Another check of this figure can be made by the actual temperature trend from 1850 to 2008, as recorded by Hadley.

    This shows a linear warming of 0.65C over the entire period (linear rate of 0.041C per decade).

    Several studies by solar scientists tell us that the high level of solar activity (highest in several thousands of years) resulted in natural warming of 0.35C (average value of these studies).

    This leaves 0.3C for anthropogenic warming (or UHI effect or high level of El Nino occurences, etc.). But let's assume that the unaccounted 0.3C warming from 1850 to 2008 was really caused by anthropogenic forcing factors.

    As IPCC tells us that all other anthropogenic factors other than CO2 essentially cancel one another out, we can assume that the 0.3C warming from 1850 to 2008 was caused by CO2, occuring over a period where CO2 increased from around 285 to 386 ppmv.

    Adjusting this to a 2xCO2 scenario, one arrives at 0.7C (very close to the above value based on physically observed feedbacks from clouds and water vapor).

    This is the theoretical anthropogenic warming we could expect from 1850 (285 ppmv CO2) to year 2100 (570 ppmv CO2).

    As we have already enjoyed about 45% (0.3C) of this theoretical warming (at 385 ppmv CO2), we can expect another 0.4C AGW warming from today to year 2100.

    This is certainly nothing to worry about.

    The actual physical observations refute the model assumption of a 2xCO2 climate sensitivity of 3.2C.  

    Instead they demonstrate that this, in actual fact, is closer to 0.6 to 0.7C, as estimated by Lindzen and Shaviv + Veizer.

    Good news for JR!

  • Joe Romm is getting hysterical again

    Wow!  Joe Romm is at it again with his latest hysterical hype.  The zippy diagram showing "Temperature--Permafrost Thaw--CO2 and CH4 released to atmosphere is another typical Joe Romm "smoke and mirrors" illusion intended to incite panic.

    JR is off in "never-never land" with his projection "we are facing catastrophic 5.7°C warming on our current emissions path just as the Hadley Center recently warned" and his even sillier statement that a "number of major paleoclimate data come to the same conclusion".

    Let's do a quick "sanity check" on JR's "permafrost thaw" disaster prediction.

    Some scientists do tell us that if temperatures continue to warm at projected rates over a very long period of time, the carbon released from thawing permafrost "could approach 0.8 to 1.1 GtC per year in the future".
    http://www.sciencedaily.com/releases/2008/09/080903134309 ...

    This compares with current human emissions:

    7.6 GtC/year from fossil fuels
    1.6 GtC/year from deforestation
    0.4 GtC/year from human respiration
    0.4 GtC/year from cement production

    10.0 GtC/year total.

    So the thawing permafrost could add (some time in the far distant future, maybe, provided the current cooling trend reverses itself) 8% to 11% to the current human carbon emission.

    This could (maybe, if it really happens that way) add 0.3C warming by the year 2100.

    Ho-hum. Don't get so hysterical. This is no big deal, Joe.

  • Déjà vu all over again...

    Hi Andrew,

    You apparently took issue with Morano when you (mis?)quoted him in saying:
    "Marc Morano agrees that only experts in climate feedbacks can make judgments on climate".

    Quoting Yogi Berra, I sort of got a "déjà vu all over again" feeling when I read these words with your name attached.

    As I recall, you used exactly this rather elitist argument around a year ago when you tried to discredit "Inhofe's 400" list.

    I agree that it is a silly argument that only "climatologists" can have a credible opinion on the various aspects within the ongoing scientific, economic and political debate surrounding the AGW hypothesis and its potential impact (or lack thereof) on humanity and our planet.

    Apparently you feel this way now, as well.

    Congratulations!

  • Note to Ian Forrester

    Aw c'mon, Ian.

    You're just angry at Roy Spencer for publishing his groundbreaking findings, based on physical observations, rather than just climate model assumptions and hype, which showed that cloud feedbacks are on average strongly negative, rather than strongly positive, as assumed by all he IPCC climate models (admittedly conceding that cloud feedbacks remain the greatest source of uncertainty).

    This is annoying to you, because it demonstrates that the 2xCO2 climate sensitivity is closer to 0.7C than to 3.2C as assumed by the IPCC climate models.

    BTW the conclusions of the study by Spencer et al. have also been validated by a completely independent study by Norris, also confirming a strongly negative feedback from clouds.

    Rejoice, Ian!

    Contrary to the hysterical hype of Hansen or the alarming predictions of IPCC, we are not doomed to die from global warming after all!

    Isn't that great news?

  • 73% of 20th century warming before 1945

    Hi Barry,

    To the previous post (pointing to the IPCC subterfuge in AR4)one could add:

    "The 40-year period 1906 to 1945 saw a linear warming of 0.54°C, compared to 0.74°C for the entire 100-year period 1906-2005. This shows that roughly 73% of the entire 20th century warming occurred before 1945."

  • Some IPCC "smoke and mirrors" for Barry

    Hi Barry,

    For a good laugh check out IPCC AR4 WG1 Chapter 3 FAQ (p.253).
    http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/ar4-wg1- ...

    You'll see a curve showing temperature trend lines.  I've copied the curve for easier viewing below.
    http://farm4.static.flickr.com/3221/2534926749_f2be35e86f ...

    You see that the closer we get to today's date the steeper the temperature curves appear to get over shorter time periods.  This looks like things are getting more alarming and are doing so at an accelerating rate.

    In its 2007 SPM report, IPCC alludes to this accelerating trend (p.5) with the sentence: The linear warming trend over the last 50 years (0.13°C [0.10°C to 0.16°C] per decade) is nearly twice that for the last 100 years" (0.074°C [0.056°C to 0.092°C] per decade).
    http://ipcc-wg1.ucar.edu/wg1/Report/AR4WG1_Print_SPM.pdf

    This is actually a bit of "smoke and mirrors".  In a record with cyclical warming/cooling periods, such as the Hadley global average land and sea surface temperature anomaly, shorter cycles will usually show steeper trend lines than longer cycles, if properly picked.

    Using the same Hadley record and the same IPCC "smoke and mirrors" approach, one can show that global warming occurred at a more rapid rate in the early 20th century than later.
    http://farm4.static.flickr.com/3249/2672880098_1ede950b42 ...

    One could then modify the IPCC statement as follows: "The linear warming trend over the first 40 years (0.135°C) is nearly twice that for the last 100 years (0.074°C per decade)."

    Both analyses are absurd, of course, but this shows how one can get a message across with proper chartmanship and bit of subterfuge.

    Just something to think about, Barry.

  • Pick your wording, Barry

    Hi Barry,

    You wrote: "Pick different periods from 1990 to the present and you'll find cool, flat and warm trends depending on how you select the data, even if you always end at June 2008."

    Been there, done that.

    If you start anytime after 2001 you will see a cooling trend.

    Now, interestingly Hadley has already started some ex post facto "corrections" to the monthly record for the first four months of 2008 (to "mitigate" this cooling trend?):

    Original record
    J -0.105
    F +0.039
    M +0.430
    A +0.250

     "Corrected" record
    J +0.054
    F +0.192
    M +0.445
    A +0.254

    The net "upward correction" for the first four months of 2008 was equal to an average of +0.083C in each month.  Hmmm...

    So your statement that you can show anything you want "depending on how you select the data" should be expanded to "depending on when you select the data".

    But I'll put the recent record into better perspective using your suggested words, "there has been a cooling trend over period 2001 to the present and this is significant because it coincides with record human CO2 emissions and raises serious questions about the validity of the IPCC prediction of 0.2C per decade warming in the early 21st century".

    Do you like that wording better?

    Regards,

    Max

    PS As a rational skeptic I get a queasy feeling in my stomach when those who are paid by the taxpayers to give the public unbiased and correct weather/climate data (Hansen, Hadley) get involved in the non-scientific process of using the data they generate to try to achieve a political agenda by inciting fear or panic in the public they are supposed to be serving and who is paying their salaries.  Don't you?  If not, you are probably not a rational skeptic but a firm believer, instead.

  • Reply to madrad

    Hi madrad,

    Let's go though your long blurb.

    "there goes your "cooler decade", 17 of the warmest years happened in the last 20. but what about 2000-2007?"

    Don't know who said anything about a "cooler decade".

    The fact is that warming has stopped since around 1998 (or, if you prefer, 2001).  

    This is a fact.  Look at the data (don't arbitrarily "chop off" the last 6 months (that would be "cherry picking")

    "all the "experts" commenting on ICECAP are well established deniers who have links to big oil.  you can match them up"

    Yawn... Another "ad hom" attack.  My advice:  stick with factual arguments and skip the "ad homs".  They just make you look silly.

    Your long list of organizations that support the IPCC view on AGW is impressive.  But science is not a "consensus" game, so these guys could all be wrong.

    We will see in the next few years if the current plateau continues or it even starts to cool how many of these organizations will quietly withdraw their support for the current "consensus" view on AGW.

    Fact of the matter is, madrad, it is not getting warmer right now for some reason or another (despite IPCC model predictions of 0.2C per decade warming), and no one knows what is going to happen in the future. Not you.  Not I.  Not Hadley. Not IPCC  Not any of those many institutions you listed.

    We'll just have to wait and see.

  • Thaw period today

    Hi Des Emery,

    You say that we are in a thaw period right now.  This may well be true compared to 1944-1976, when we were apparently in a cooling cycle.  As the record from Greenland shows, we were also in a "thaw period" in the 1930s (at 50% more rapid warming than the most recent period and very much lower increase in atmospheric CO2 concentrations).

    The most recent period shows cooling again, but whether or not this will become a trend is anyone's guess. I sincerely hope not, because we do not need a colder world.

    The historical record shows us that we go though multi-decadal warming/cooling cycles with an underlying warming trend of 0.6 to 0.7C per century, and we have been doing this since the record started in 1850 (and we started coming out of the Little Ice Age).

  • Reply to Des Emery

    Hi Des Emery,

    You wrote:
    "...ice would certainly have had time to re-establish its presence if GW was indeed over.
    I believe this evidence is more compelling than any temperature graph analysis to prove that GW is indeed happening, and at an accelerating rate. this is occurring in a global territory, unlike temperatures which are local events influenced by many factors."

    Whether or not the ice has "re-established its presence" is a moot point.  Globally seen (Antarctic plus Arctic) it now stands (June 2008) at an extent that is slightly higher than the 1979-2000 average for the month of June:

    Arctic
    11.44 million sq.km.
    0.76 million sq.km. (6.2%) below the 1979-2000 average extent

    Antarctic
    15.46 million sq.km.
    1.0 million sq.km. (6.9%) above the 1979-2000 average extent

    Overall the ice has grown by 0.24 million sq.km. (0.9%) above the 1979-2000 average.

    This does not "prove that GW is indeed happening" and certainly not that it is happening "at an accelerating rate".

    In fact, it does not prove anything about GW, except that overall the sea ice has globally increased slightly from the baseline period of 1979-2000 average to today.

    Yes, "temperatures" are "local events influenced by many factors".  I would certainly agree.  

    For that reason I also have little faith in a "globally averaged land and sea surface temperature anomaly" as any kind of a meaningful indicator.  

    Compounding the problem are the many adjustments, corrections and manipulations that are made to arrive at this indicator (including ex post facto corrections that are made to the historical record), the many demonstrated problems with weather station locations near urban areas, local problems (asphalt parking lots, AC exhausts, buildings, etc.), shutdown of many rural stations (particularly a large number that were shut down in remote high-latitude Siberian locations when the USSR broke up), etc.

    But (together with the satellite record that shows a slightly slower rate of increase in the troposphere than the surface record), this is all we have.  

    And this admittedly questionable record has not shown an increase in temperature since 1998 after having shown an increase of somewhere between 0.13 and 0.17 degrees C per decade over the 22-year IPCC "poster period" 1976-1998 (linear increase of 0.37C over the period), slight cooling from 1944-1976 and another increase of 0.15 degrees C per decade from 1910-1944 (linear increase of 0.53C over the period).

    If one makes the break at the "start of the 21st century" (January 2001) it shows the same flat to slight cooling trend.

    The correlation with atmospheric CO2 concentrations looks good for the IPCC "poster period" but rather poor for the other periods.

    To your statement: "The picture of the state of the Earth cannot be compartmentalized, but should be seen as a kind of "panorama" of effects.  And the co-incidence of real-time events has to worked into the equations, not just dismissed as "interesting but separate" items."  I would agree.  

    It's all part of a bigger picture that may or may not have very much to do with human CO2 emissions.

  • An IPCC "anomaly" for Barry

    Hi Barry,

    Here's one for you to check out, now that you are working with Excel on global temperature trends.

    In the "Frequently Asked Questions" Section 3.1 (p.103) of the IPCC AR4 WG1 report, IPCC makes the statement: "Above the surface, global observations since the late 1950s show that the troposphere (up to about 10 km) has warmed at a slightly greater rate than the surface..." "This is in accord with physical expectations and most model results, which demonstrate the role of increasing greenhouse gases in tropospheric warming..."
    http://www.ipcc.ch/pdf/assessment-repor ... 1-faqs.pdf

    A look at the actual records from 1979 (when satellite records started) to 2005 (last year included in AR4 report) tells a different story.

    Record    linear trend    linear change C                           
        C/decade    over period                           
    Surface                                   
    GISS    0.174    0.45                           
    Hadley    0.167    0.43                           
    Average    0.171    0.44                           
    Satellite                                   
    UAH    0.139    0.36                           
    RSS    0.192    0.50                           
    Average    0.166    0.43                           

    The average surface rate is 3% higher than the satellite (troposphere) rate, so the IPCC statement is false.  

    The troposphere has not warmed at a "slightly greater rate" than the surface and the conclusion "which demonstrate the role of increasing greenhouse gases in tropospheric warming" is therefore also incorrect.

    Just another strange "anomaly" in the IPCC report on temperature you may wish to check out for yourself..

  • Some cloud info for qzuckier

    Hi qzuckier,

    Believe you mentioned "clouds" in your otherwise rambling post of 9 July (7:21 AM).

    Yep.  It looks like clouds do have a "feedback" effect, only this is not a "positive" (warming) feedback, as programmed into the GCMs, but rather a strong "negative" (cooling) feedback as confirmed by physical observations.

    In August, 2007, Roy Spencer published an article in Geophysical Research Letters outlining this observed cloud feedback.
    http://blog.acton.org/uploads/Spencer_07GRL.pdf  

    The AGW hypotheis postulates a number of positive feedbacks which will accelerate the warming. One of the feedbacks programmed into the GCMs is a positive (warming) feedback from a theoretical increase in high-level, heat trapping clouds.

    Spencer's physical observations in the tropics found a strong negative feedback from clouds instead.

    This observation gives validation to Richard Lindzen's "infrared iris" hypothesis of climate stabilization. "
    http://ams.allenpress.com/archive/1520-0477/82/3/pdf/i152 ...

    The name "adaptive infrared iris" refers to the mechanism in which the tropical ice cloud cover opens and closes in response to tropical ocean temperatures to allow more heat to escape to space when the oceans are warm and less heat to escape to space when the oceans are relatively cool (much like the iris of an eye which opens and closes in response to varying light levels to try to maintain a constant level falling on the retina). Lindzen et al. proposed that the iris acts as a global thermostat that will keep the earth's temperatures from rising very far even as atmospheric concentrations of greenhouse gases increase.

    To give an idea of how strong this "negative feedback" or enhanced cooling mechanism is, "if it was operating on global warming, it would reduce estimates of future warming by over 75 percent," Spencer said. "The big question that no one can answer right now is whether this enhanced cooling mechanism applies to global warming."

    Spencer has summarized his findings in a more recent update, in which he concludes that the current climate models are projecting exaggerated warming from greenhouse gases by not taking this natural negative feedback into account:
    http://www.weatherquestions.com/Recent-Evidence-Reduced-S ...

    Just some facts on clouds that may be interesting to you.

  • Ome sea ice figures for Des Emery

    Hi Des Emery,

    Checked for some figures on Arctic and Antarctic Sea Ice
    http://icecap.us/images/uploads/SOLSTICE_SEA_ICE_UPDATE.p ...

    Most recent record of sea ice (June 2008) shows:
    ·    Arctic sea ice extent is 11.44 million sq km; this is 0.76 million square km below the 1979-2000 baseline mean for June
    ·    Antarctic sea ice extent is 15.5 million sq km; this is 1.0 million square km above the 1979-2000 baseline mean for June

    So in total sea ice extent has grown slightly as compared to the 1979-2000 baseline mean.

  • A correction for Des Emery

    Hey Des Emery,

    You are (as you say) "way out in left field" when you write: "If GH stopped back in 1998, ten years would be sufficient time for ice to at least start re-forming in its former environs."

    The temperature record is self-explanitory, i.e. no warming since 1998. There is no "accelerating rate", as you claim.  This is pure fiction. Just check the record.

    As far as sea ice is concerned, these things take time and are not directly related in any case, but, yes, ice has started reforming in the Arctic and has continued to grow in the Antarctic over the period.  Check the latest record compared to most recent earlier years (Arctic as well as Antarctic sea ice).

    Looks like there is no real need to be concerned despite all the hype.

    Just look at the facts on the ground. This will help you get a clearer picture despite all the hype out there.

  • Bye, Barry

    Hi Barry,

    I'm going to have to say it as it is: you are totally confused and this`exchange with you is getting repetitive to the point of being boring.

    All of your waffling on when a trend was started is irrelevant.  Get it through your head.  It has stopped warming since 1998.

    Now Black Wallaby may explain to you how after a peak high year we have had a couple of lower than average years. This appears to have happened in 1999 and 2000.

    But the main point is that the record shows that there has been no warming for the past 10 years.

    Is this the start of a new long-term trend? Who knows?  You don't.  I don't.  Black Wallaby does not.  Even the "gurus" at Hadley do not.

    Remember that the last warming trend only lasted 22 years (1976-1998), so 10 years is already a significant period of time.

    Face it, Barry.  As the lead article here stated back in November 2006, "Global warming stopped in 1998".  The 1-1/2 years since this site was opened have only confirmed this even more strongly.  The past 6 months since the start of solar cycle 24 have provided even stronger confirmation of this fact:

    "GLOBAL WARMING STOPPED IN 1998"

    Got it?  Is there some part of that which you are unable to grasp?

    We are wasting time in this discussion.

    Learn some basic skills (like Excel) and check things out for yourself.

    End of our discussion.

  • Explanation for Barry


    Hi Barry,

    You asked: "Please explain why you begin your trend analysis at 2001 and not 2000 or earlier."

    I began it with the start of the 21st century (officially January 1, 2001).

    Starting with 1998 has been criticized by some as "introducingan artifact" (since 1998 was the all-time record ENSO year).

    Any objection?

    If so, why?

  • Include all the data, Barry

    Hi Barry,

    You wrote: "Certainly. You have selected a different time series; 2001 - May 2008.

    Please explain why you have chosen this period."

    Because it is the most recent time period for which we have data.  

    To exclude the last 5 months of data in establishing the most recent trend would be silly, wouldn't it?

    We are trying to determine what is going on now, so we have to include all the recent data.

    Does this not make sense to you?

  • Welcome Des Emery

    Hi Des Emery,

    Welcome to the discussion (agree that the discussion with Barry has gotten a bit repetitive).

    You advised: "BTW, I trust you are using the correct method of recording temperature change.  Annual linear graphs are not reliable.  Averages have to be computed in cycles, that is (for instance) from l970 to l979, then from l971 to 1980, then from 1972 to 1981, and so on.  Comparisons between the results then mean something."

    Agree that one has to look at the multi-decadal warming / cooling cycles to make any sense of what is going on:

    1858-1879: 0.38C linear warming
    1879-1910: cooling
    1910-1944: 0.53C linear warming
    1944-1976: cooling
    1976-1998: 0.37C linear warming
    1998-2008: flat to slight cooling

    These are the cycles one has to compare. One should also try to find some link between what happened to temperature during these cycles to solar changes, volcanoes, changes in GHGs, etc., to see is there is any correlation.

    Doesn't have too much to do with Arctic or Antarctic sea ice, Kilimanjaro, Borneo, though.  These are interting (but separate) topics.

  • Let's look at the whole record, Barry

    Hi Barry,

    Looks like the Hadley assessment ignores the last 5 months of data (January through May 2008).

    My analysis does not.

    Can this be the cause for the discrepancy?

    Who knows?

    It would be foolish to ignore the last 5 months of data, so I cannot imaging that an updated Hadley analysis would do something so silly.  Can you?

    Must be an older (and now outdated) analysis.

  • Barry is wrong again

    Hi Barry,

    Just noticed that you posted the following statement: "As to Watt's top post, he also mixes science with politics and his 'trend', if there is any, is derived from picking just two months (June) in the whole series and comparing them. He neglects to mention that UAH and RSS both find a significant increased decadal temperature trend, even over the short period of readings."

    This is false, Barry.  Watts does an excellent job of substantiating his statements with the actual records he cites.

    Both UAH and RSS records do, indeed, show a cooling trend since 2001 (as does the Hadley record, which we have already discussed to death).

    Again, once you have mastered Excel, you can check this out for yourself.

    I already have, and have confirmed to my satisfaction that Watts' statements are absolutely correct on this cooling trend since 2001.

    Just stick with the facts, Barry, not a lot of "blather" about mixing "science with politics".

  • Excel test for Barry

    Hi Barry,

    Once you have mastered Excel, here is a test for you.

    Download the monthly Hadley global average land and sea surface temperature anomaly figures as they are published, starting with January 2001 and ending with May 2008.

    Plot them into Excel.

    Once you have plotted them, draw the linear regression trend line and under "options" click "display equation" and "display R squre value".  Both will appear on your curve.

    From the equation you will see a function that looks like: y = b*x + a

    b is the linear trend (this time in months, so you have to multiply by 120 to get a trend line per decade).  This will tell you what the linear trend has been from 2001 to today.

    You can then compare this with any trend that anyone else has either predicted or claimed for that period.

    Let me know what you find out once you have gotten that far, Barry. (I already know the answer, because I've already done the steps outlined above.)

    This will help you in being more rationally objective and in being to make up your own mind on what is going on out there, despite all the hype.

  • Facts are facts, Barry

    Hi Barry,

    You wrote: "BTW, as your trend analysis for the last decade is at odds with Hadley's (+0.1C), presumably using the same data, to what do you attribute the discrepancy?"

    Barry, there is no "discrepancy".  The records all show that the period 2001-2008 has shown a flat to cooling trend.  That is the established fact.

    That is why your statement (5:23 pm 5 July 2008)that "it has continued to warm since the TAR was published (2001)" is incorrect.

    Check the records yourself and you can confirm this. This is not that hard to do, once you have acquired the basic skills to do so.

    If "Hadley says otherwise" (as you claim), they are not telling the truth.  It's just that simple. Facts are facts, Barry.

  • Facts for Barry

    Hi Barry,

    Let's cut the crap (as they say) and get down to the basics of our discussion.

    The recorded facts show that it has not warmed from 2001 to 2008 despite record human emissions of CO2.

    The same is also true for the period 1998-2008, but let us ignore that for now.

    In fact, three of four records (UAH, Hadley, RSS) show it has actually cooled since 2001.

    The third record (GISS) shows it has been flat.

    Can you please confirm to me that you understand and accept this?

    If you do not accept the recorded facts, why not?

    Please avoid long-winded waffling and stick to the facts.

  • Minor correction for Barry

    Hi Barry,

    Sounds OK to me except your statement: "Clearly, the world's surface temperature has continued to increase since the TAR and the trend when computed in the same way as in the TAR remains 0.6°C over the 20th century."

    The second part of the statement (20th century trend) is OK, but the first part is not.

    The TAR came out in 2001.

    It is now 2008.

    The trend from 2001 (when TAR was published) until now has been one of slight cooling in all records, except GISS, where it is flat.

    So it is not correct to say that "the world's surface temperature has continued to increase since the TAR".  It would be more correct to say: "Clearly, the world's surface temperature has NOT continued to increase since the TAR", (since the records all show that this is what happened).

  • some more funny numbers for greyfalcon

    Hi Greyfalcon,

    Nice to see you back.

    The RealClimate link to "correcting for the ENSO signal" is a real "hoot"!  Cool.

    Just did the same sort of look-see for "correcting for the CO2 signal".

    Start of 1998, CO2 was 363 ppmv
    End of 2007, CO2 was 383 ppmv

    Ratio, End/Start, = 1.0551

    ln (1.0551) = 0.5363

    5.35 * 0.5363 = 0.2869

    (using IPCC figures for RF per Myhe et al)

    Stefan-Boltzmann = 5.4273

    Temperature rise due to added CO2 = 0.2869 / 5.4273 = 0.0529C

    So by cutting out 0.0529C over the 10-year period (on a year by year basis, of course) we can "correct the record for the CO2 signal".

    Trouble is, there was no increase in temperature over the period.  Hmmm...

    Just goes to show what you can do by jiggling numbers around.

  • Hadley record

    Hi Barry,

    You are starting to ramble here, Barry. Believe we have discussed this issue to death.

    The Hadley record is what it is.  It is available to the public.  Anyone who is so inclined can download the data directly.  It is very straightforward.

    The global average land and sea surface anomaly as currently published for the period 1901-2000 shows a linear increase of 0.65C over the period.  This is not an "interpretation" of the record.  It is the mathematical linear trend of the published record. Excel makes it easy to establish this trend line and equation without the drudgery of doing this manually.

    The record apparently gets "corrected" or "adjusted" after the fact from time to time.

    This is (according to you quoting a Jones 2001 study, I believe) what happened to the 1901-2000 record some time after IPCC published the TAR.

    The net result of this was that the linear warming over the entire period (1901-2000) changed from 0.6C (as was reported in TAR) to a linear warming of 0.65C in the current record.

    I cannot vouch for the earlier 0.6C figure but I can vouch for the current 0.65C figure (because that is what the figures show).

    Now to your statement:

    "Surely you can understand that it is entirely reasonable for me to trust a reputable institution (Hadley) at least as equally as an anonymous internet poster (you). Until I can do the math, this is the fairest position to take. If I simply swallowed what you said hook line and sinker, without the skill to verify, I wouldn't be a very good skeptic, would I?

    You are making the firm assertions here, not I. I am considering your points pending my own education on the matter. I can't think of a better way to go about it. You appear to want me to believe, and are impatient because I don't have complete, unquestioning faith in your abilities. Surely you're not asking me to take what you say on faith? Isn't that what 'alarmists' do regarding the IPCC?"

    Barry, I have no notion what you are trying to say here, but you are free to believe anything you want to.

    The record is the record.  That's all.  

    Take an Excel course and you'll be able to download the raw data and draw your own linear trend line and conclusions.

  • Some basic arithmetic for Barry

    Hi Barry,

    I'll try to be patient and clear up any confusion you may still have.

    "Still trying to get educated on running the trends myself, or getting an independent party to do it."

    Good idea, Barry.

    "That doesn't follow. If Hadley revised the 20th century trend upwards, in line with your calcs, the result would be less of an increase when compared to AR4, not more. If IPCC wanted to show an increasing trend, they'd want to revise the TAR trend downwards"

    Barry, it appears that you have a problem with arithmetical calculations.  Let's see if we can make this easier to grasp without getting into hypothetical discussions of what "they'd want to" do.

    Prior to TAR (2001) Hadley reports that the 1901-2000 linear temperature increase was 0.6C.  IPCC reports this figure in its TAR report.

    According to you (based on a report by Jones in 2001, which you cite) Hadley later revised their record for 1901-2000 from 0.6 to 0.65C, which is exactly what their current record shows.

    In other words, Hadley corrected the record "ex post facto" to show 0.65C warming rather than 0.6C warming over the 20th century period from 1901 to 2000.  This could not be captured in the IPCC TAR because it occurred after its publication.

    Are you still with me, Barry?

    In the later AR4 report of IPCC they "shifted" from 1901-2000 to 1906-2005 and reported the Hadley linear warming over this new period as 0.74C.

    So far, so good.

    They then insinuated (with the word "therefore") that the increase in the 100-year warming by shifting from 1901-2000 to 1906-2005 was a result of the warming, which occurred at the end of the period (i.e. 2000-2005).

    Are you still following, Barry?

    This was a lie. Did you get this?

    The record shows that the apparent 0.14C difference was caused by
    ·    The 0.05C "adjustment" described above
    ·    A 0.09C difference between the strong cooling trend 1901-1905 and the flat to slight warming trend 2001-2005

    Are you still following, Barry, or have I lost you?

    If you are having problems, go back to the top of this post and repeat.

    Don't try to play me for a fool, Barry.

  • Message for Barry Schwarz

    Hi Barry,

    Thanks for Hadley data.  This is same yearly data I have (and have used for the long term trends).

    For the most recent plateau I used monthly data, since these capture what has been happening since late 2007.

    You wrote: "Do you by any chance have a link to or copy of the data sets that Hadley used in 2000/2001? That should settle the matter of whether TAR screwed up, if the Jones 2001 study and the October 2001 Hadley report corroborating the TAR figure don't suffice for you."

    No, I have not checked this out.  It's not really a matter of "whether TAR screwed up" or not.  I can accept that Hadley made some "ex post facto" adjustments to their 1901-2000 record after TAR was published, if that is what the Jones 2001 study shows.

    So IPCC did not "screw up" in TAR.

    But IPCC lied in AR4 when it insinuated (with its word "THEREFORE") that the increase of 0.14C, which resulted from the shift from 1901-2000 (TAR) to 1906-2005 (AR4), came as a result of rapid warming from 2000-2005.

    In actual fact the apparent +0.14C increase came from:
    ·    Correcting an error of +0.05C in the Hadley record (1901-2000)
    ·    +0.09C from replacing a sharp cooling trend over the period 1901-1905 with a slight warming trend over the period 2001-2005

    But we've gone over that already.

    Good that you are getting Excel so you can go to the published source data directly.  It is really the best way to cut through all the hype out there.

    Hi amazingdrx,

    Your link to an 8-month old article about dwindling Arctic sea ice is out-of-date.

    You really should keep up-to-date on what is going on out there.

    The May 2008 link I cited shows no net reduction in Arctic sea ice from May 1989 to May 2008.

    And your link to the gristmill projection for what "could happen in the future" is total conjecture (besides having nothing to do with AGW).

  • Some answers for Barry

    Hi Barry,

    Thanks for long post.  Let's go through your queries / statements one by one.

    "I agree that the language in the SPM bit you cited is questionable."  Yeah, Barry, it is "questionable".  In fact it is downright dishonest.  It insinuates one thing (rapid warming 2000-2005) when this is not happening. Unfortunately, there are other examples where IPCC has used this approach.

    "In 2001, Hadley's trend for the 20th Century stood at 0.6C. I've corroborated that from the source study, and also from a Hadley newsletter, both from 2001. The TAR stated the trend as Hadley had put it then. The methodology used to arrive at that figure is probably a bit more complicated than whatever you're doing in Excel. Check the study, and read here on Linear regression."

    Actually, Barry, that is exactly what Hadley (and IPCC) do in order to calculate a linear trend. It is also exactly what I did.  Whether one does this manually (I've done these in the past before we had the good programs of today) or by using Excel, the answer is the same.  You end up with an equation that takes the form: y = b * x + a where y = temperature anomaly, x = year and a is a constant equal to y at year 0 or start of graph. So Hadley's approach to linear regression is not "a bit more complicated than whatever you're doing in Excel".  It is exactly the same, Barry. And it results in exactly the same answer.

    "I have good cause to question your methodology. You say there has been a flat trend in the last 10 years. Hadley says the trend has been 0.1C. Check this update from Hadley."

    The Hadley statement in the cited reference states: "A simple mathematical calculation of the temperature change over the latest decade (1998-2007) alone shows a continued warming of 0.1 °C per decade."  This (like the IPCC AR4 statement we analyzed earlier) is a misleading statement, Barry.  No mention is made of which type of "simple mathematical calculation of the temperature change over the last decade" is being referred to. It is certainly not a linear regression analysis (the normally accepted method of establishing trends).

    If we download and plot the last 120 months from the Hadley monthly record and plot these, the Hadley record shows there has been a flat linear trend in the last 10 years.

    Now, as I pointed out to you earlier, there are some people who object to starting the most recent linear trend with the all-time record ENSO year 1998, since doing this would "introduce an artifact".  So I have also taken the Hadley monthly record starting with January 2001 (start of the 21st century) and plotted it to today (April 2008).

    Both graphs are shown in the attachment.
    http://farm4.static.flickr.com/3134/2591260894_011a1a6c9c ...

    The 2001-2008 trend shows a bit more cooling than the trend starting in 1998 (despite the record ENSO year).

    Linear trend = -0.084C per decade
    Or -0.07C over 7+ year period

    As you can see, Barry, this is not a linear trend of +0.1C (warming) per decade, no matter what the Hadley "blurb" states. In fact, it is (starting with 2001) a linear cooling of almost -0.1C per decade!

    Sometimes it pays to go back to the source data, Barry, and draw your own conclusions, rather than relying on someone else's interpretation of what is going on out there.

    Hope this helps clear this up.

  • Check the facts amazingdrx

    Hi amazingdrx,

    The facts show that there has been no net decline in Arctic sea ice from May 1989 to May 2008 (19 years), due to the major increase this past year.

    At the same time Antarctic sea ice is growing steadily.

    But gristmill still "predicts" a sea ice disaster.

    Get serious, amazingdrx, it's a hoax.  Forget gristmill.  Check the facts out there, not the alarmist sites.

  • Some facts on Arctic sea ice

    Arctic sea ice extent for May 2008 was 13.18 million square kilometers, reaching the same level as in May 1989.

    This is 2.5% below the baseline level (1979-2000 mean May level of 13.6 million square kilometers) and around 4.5% above the record May low reached in May 2004

    The linear average rate of decline is 3.0%/decade (over the 30-year period since measurements have started).  If the decline continues at this rate, it will take 330 years for the entire Arctic sea ice to disappear.

    The most recent decline has however not continued at the 3.0%/decade rate, since the May 2008 extent is back to the May 1989 extent (i.e. zero net decline in 19 years).

  • Just one more point, Barry

    Hi Barry,

    Just one more point.

    You are apparently telling me that Hadley revised (i.e. corrected) their 1901-2000 number from 0.6C to 0.65C some time after IPCC published the TAR.

    So 0.5C of the apparent "increase" from shifting the 100-year period by 5 years (from IPCC TAR to AR4) comes from correcting an earlier error in the data.

    So when IPCC says the following:
    "Eleven of the last twelve years (1995-2006) rank among the 12 warmest years in the instrumental record of global surface temperature (since 1850).  The up-dated 100-year linear trend (1906 to 2005) of 0.74°C [0.56°C to 0.92°C] is THEREFORE" [caps. by me] "larger than the corresponding trend for 1901 to 2000 given in the TAR of 0.6°C [0.4°C to 0.8°C]."

    They are insinuating with the word "therefore" that the apparent 0.14C increase from shifting the 100-year period by 5 years comes from an increase in warming rate at the end of the period (2001-2005).

    In actual fact it comes from correcting an earlier error in the Hadley data (0.05C) and from removing a 5-year cooling period (0.09C)from the front end of the record (1901-1905).

    So IPCC conveys a false picture of increased warming in the early 21st century rather than telling the reader what really happened.

    Why do they not tell the reader the true story?

    This is shocking.

  • Bye Barry

    Hi Barry,

    You're right.  This exchange is getting repetitive.

    You wrote: "I asked you who made those graphs, and for some information on the methodology used.

    Who made the graphs? Who did the trend analysis? What was the method used?"

    I will repeat what I told you earlier:

    I simply downloaded the raw data as published by Hadley (source cited) into Excel, plotted the graph and put in a linear trend line, and calculated the equation for the decadal trend.  All part of the Excel software.  No black magic.  No voodoo.  No "levelling".  No "adjusting".  No "averaging". No "interpretation" of the data by any "scientist" or "computer nerd" who may be wanting to convey a hidden message.  Just the plain old unvarnished facts.  That's all.

    Shows a flat trend from 1998 to today and a slight cooling trend from 2001 to today.

    And it shows 1901-2000 linear increase of 0.65C, as I told you earlier.

    Hope that clears it up for you.

    It's really quite basic.

    "I could not find a reference at the UK Met office for the 1901 - 2000 series used in TAR having a warming trend of 0.65C, per your advice to check it. I went to the source study Hadley used at the time for the period (Jones et al 2001 - cited in TAR), where I found this;
    The 20th century experienced the strongest warming trend of the millennium (about 0.6C per century).
    I could find no reference to 0.65 for that period (1901 - 2000) from Hadley or anywhere else. Could you please provide a clearly referenced cite re Hadley 1901 - 2000 temperature trend of 0.65C to corroborate your claim that IPCC got it wrong?"

    Some advice, Barry: Download the actual Hadley data into Excel, as I did.  Then draw a linear trend line, as I did.  You will see this on the curve of Hadley data that I provided. It shows a linear trend of 0.65C over the period 1901-2000, which IPCC in the TAR (and possibly Jones et al) rounded down to 0.6C.  No big deal, Barry.

    It is very simple and basic, if you have basic Excel skills.  If not, get some help from someone who does.

    The point was that IPCC SPM 2007 insinuated with the use of the word "therefore" that the increase from 0.6C to 0.74C which resulted from the five-year shift was a result of the increased warming trend at the end of the period (2001-2005) rather that from eliminating a cooling trend from 1901-1905 from the record (which was the actual cause for the increase).  Did you understand that, or is this too complex for you?

    Try to use your head a bit, Barry.

    Hey Barry,

    I have given you the source of the data in the graphs.

    If you are too lazy or not competent enough to download the raw data yourself and check the graphs, that's your probem.

    Your long-winded waffle just shows you have not really understood any of this stuff.

    You claim that Hadley has said: ""A simple mathematical calculation of the temperature change over the latest decade (1998-2007) alone shows a continued warming of 0.1 °C per decade."

    This is hogwash.  Check the numbers yourself, if you are able to do so.  They show a flat to slight cooling trend, as the graphs of Hadley data I provided clearly show.

    Making silly claims and sending long-winded irrelevant waffles does not change the recorded facts, Barry.

    Grow up.

  • GIGO predictions from Christophersj

    Hohum!

    Christophersj posts another absurd "prediction" by noaa nerds concerning horrible droughts and floods we are already "beginning to see" (?) and will surely see increasingly in the future, because of human CO2 emissions, all based on IPCC reports.

    GIGO projections intended to arouse alarm and support for carbon taxes or cap and trade scams.

    That's what it is, Christophersj.

    Hey folks,

    Nucbuddy's right.  We don't need all those scaly, furry, feathery and six-legged critters around to survive.

    But the main point is that they are not in any real danger whatsoever from our CO2 emissions.

    Despite all the hype out there, they are doing jes' fine.

    And the GIGO predictions of their future demise in the future because of our CO2 emissions are just that.

    You wrote: "show me a climate scientist who does NOT say that temporary local and even global plateaus and pauses, and even slight reversals, in warming can occur, all the while the long term trend is up."

    This is entirely beside the point.

    The trend is "up". Duh! All you have to do is look at the record since 1850.

    There just isn't a real good correlation between CO2 and temperature, except for the 1976-1998 period.

    And, with a total 20th century increase of 0.65C (Hadley), there is not much evidence of any feedbacks.  You can arrive at that value just with CO2, CH4 and solar influence without any postulated or assumed feedbacks to create a "climate sensitivity" (2xCO2) of 3K. It's more like IPCC says (without feedbacks) = 0.7K.

    That's the point, Christopher.

    Not that there has not been warming.  Just that it is not very alarming and appears to have slowed down most recently, although no one (not even the GCMs) know for how long.

  • Recent decline in extreme weather events

    Catman asked (21 June) "I've been wondering if anyone has been keeping track of these climate extreme events for at least 20 years but never heard a word about it until this week."

    Yeah.  There is an excellent summary out there that goes back even further.  It shows that there has been a dramatic decrease in extreme weather events recently compared to earlier times, despite all the model projections to the contrary (pp.49-50).
    http://www.globalwarming.org/files/report_20.pdf

    Of course, it was published before the recent cold period starting last winter that brought snow to southern China, the Middle East, etc., extreme cold to Canada, plus strings of tornadoes to the US Midwest and floods on the Mississippi in its wake.  

    And of course the "model guys" aren't going to admit this.

    Hi Barry,

    Back to the "last 10 years plateau".  It's real, Barry, which should actually be good news for those concerned about a threat from AGW.

    I have plotted the raw monthly data from Hadley, GISS, RSS and UAH for the periods 1998-2008 as well as for the period 2001-2008 (since some people "object" to starting the period with the all-time record ENSO year 1998, as this would be introducing an "artifact").

    The curves are attached (references cited on each curve for your info if you want to go back and check the validity).

    Read `em and weep (or rejoice).

  • Reply to barry schwarz

    Hi Barry,

    Thanks for you long post.  I'll try going through it point by point.

    First you state, "I often find that values attributed to the IPCC are at odds with what it actually says."

    This checks with my experience, as well, in both directions, as a matter of fact.

    But I have also found that those who want to "believe" in the IPCC message often tend to overlook errors, omissions, exaggerations or outright inconsistencies in the IPCC reports, rather that to identify and challenge these, as a rational skeptic should do in following the scientific process.

    To your next point.

    In the TAR (2001) IPCC made reference to 20th century warming, which it defined as the period 1901-2000 (i.e. the "20th century, as we know it). It referred to the Hadley surface temperature anomaly record in saying that this showed a linear warming of 0.6C over the century.  Now, if one actually checks the linear increase over the period 1901-2000 according to the Hadley record, one sees that this was actually 0.65C, rather than 0.6C as reported by IPCC.  A minor error.

    Now to the latest IPCC SPM 2007 report.
    http://ipcc-wg1.ucar.edu/wg1/Report/AR4WG1_Print_SPM.pdf

    You will note that IPCC (p.5) now states:
    "Eleven of the last twelve years (1995-2006) rank among the 12 warmest years in the instrumental record of global surface temperature (since 1850).  The up-dated 100-year linear trend (1906 to 2005) of 0.74°C [0.56°C to 0.92°C] is THEREFORE" [caps. by me] "larger than the corresponding trend for 1901 to 200 given in the TAR of 0.6°C [0.4°C to 0.8°C].  The linear warming trend over the last 50 years (0.13°C [0.10°C to 0.16°C] per decade) is nearly twice that for the last 100 years."  

    Now, by the use of the word "therefore" (which I capitalized for emphasis), IPCC is conveying the impression that the 100-year increase of 0.14°C, from 0.6°C to 0.74°C (which should actually have been an increase of 0.09°C, from 0.65°C to 0.74°C) was caused by adding years 2001-2005 with rapid warming).

    A detailed look at the Hadley record shows that this is not true.

    The increase of 0.09°C over the 100-year period (not 0.14°C  as erroneously reported by IPCC) came from removing a cooling trend from 1901-1906, and NOT from adding a period of rapid warming from 2001-2006, as suggested by IPCC by inserting the word "THEREFORE".  In fact, the linear trend over the period 2001-2006 was essentially "flat".

    If you would like to see the graphs of the Hadley record confirming all of what I have said above, please let me know.  I will post them separately since they sometimes cause problems with the spam filter on this site if too many are posted together.

    Now to your point: "I note also that the IPCC averages from the 3 main instrumental temperature records, not just Hadley."

    This is not correct.  If you take the time to download the Hadley record as is it reported, you will see that it is exactly the same as the IPCC record over the entire 20th century.  Other records are slightly different and no others go back to 1850.  But this is a minor point. The "odd-man-out" record (especially in the post 1980 period) is the GISS, managed by James E. Hansen.  With Hansen's shift from "objective scientist" to "AGW political activist" plus the recent disclosures of errors in the USA GISS record, I have a bit more faith in Hadley than GISS today.  The satellite records (UAH, RSS) also check more closely with Hadley trends than they do with GISS.

    Now back to your: "I often find that values attributed to the IPCC are at odds with what it actually says."

    We have seen from the above example that "what it actually says" must be expanded to include "what it actually implies by saying what it says".  By adding the word "THEREFORE" the clear implication is something totally different from the actual facts.

    But there is also the very important part of "what it doesn't say".

    A look at the Hadley record (or any other record) shows that temperature has gone through three periods of rapid warming between 1850 to 2005 with three periods of slight cooling in between and the current plateau since 1998, with an underlying linear trend of warming over the entire period.

    This is sort of a tilted sine curve.  Now anyone who thinks about this just a little bit can see that be properly picking shorter cycles within this overall period can demonstrate that these shorter cycles nave a steeper linear slope than the longer cycle (that incorporates more than just one sine curve).

    When IPCC tells us (see quote above) that the linear trend of the past 50 years (1956-2005) is steeper than that of the full 100 years (1906-2005) it is doing exactly this.

    One could do the same in reverse (a reverse "cherry pick") by saying the linear trend from 1910 to 1944 was steeper than the linear trend from 1910 to 2005, thereby insinuating that warming has slowed down over the century.  This would be as misleading as the IPCC statement hinting at the opposite conclusion.

    Again I can send you curves of all this if you are interested.  But I will just attach one curve from IPCC AR4 Chapter 3 FAQ 3.1 Figure 1, which is an extreme example of this "smoke and mirrors" approach.
    http://farm4.static.flickr.com/3221/2534926749_f2be35e86f ...

    Can you see the implication in this curve that things are getting worse as we move along in the 20th century?  It is clearly there (if only implicitly stated).  But if we start at the front of the overall curve and make linear trend lines of ever increasing increments always starting from the front, we will see exactly the opposite trend.

    This would be just as misleading as the IPCC presentation, of course.

    Now you get into something a bit more personal, and I don't know if you are addressing it to Black Wallaby or to me:

    "You both present them [curves of Hadley data?] as if they're authoritative. Can you understand that it's hard to give them credence?
    You've stated upthread that you use IPCC trend methodology. If I assume this is the case with the graphs you have referenced, how am I to reconcile the first 25 or 50 year higher trend with this;
    "The rate of warming over the last 50 years is almost double that over the last 100 years (0.13°C ± 0.03°C vs. 0.07°C ± 0.02°C per decade)."
    Either you, your source, or the IPCC is in error. I don't have the skills to do any analysis to see for myself whether this
    Obviously, this analysis is just as phoney as the one made by IPCC
    is true. But I think it's more reasonable to trust the IPCC trends over anonymous graphs, and not reasonable to credit claims that are demonstrably at odds with the source referenced (IPCC - but I'll wait for direction from you re IPCC statements that match your assertions)."

    Believe I have answered the "last 50 years is almost double the last 100 years" question above.  It is not at all inconsistent with "the first 25 (or 50) year is higher that the entire 100 years". Shorter periods picked out of a long-term sine curve (if properly selected) will always show steeper linear trends than the long-term curve.  Just look at the IPCC curve I linked above.

    As to the source of data, I believe in all of the curves I have linked I have shown clearly where the data have come from. If you have any specific questions, please advise, but do not come with "but I think it's more reasonable to trust the IPCC trends over anonymous graphs, and not reasonable to credit claims that are demonstrably at odds with the source referenced (IPCC - but I'll wait for direction from you re IPCC statements that match your assertions)", since this smacks of accusatory BS.

    I have made no "claims that are demonstrably at odds with the source referenced".  If you think that I have, please be a bit more specific, so I can clear up your obvious confusion on this point.

    I know you WANT to believe the IPCC claims, so it is reasonable to assume that you will automatically think that it is more reasonable to trust IPCC trends over someone's rationally critical appraisal of these IPCC claims, even if the critical appraisal is backed up by the same source data used by IPCC.  But this is all philosophical conjecture.  If you have specific points where you want more backup data, please state specifically what there are rather than just making "broad brush" disparaging remarks.  OK?

    Hoping to have answered most of your questions and looking forward to hearing back from you with something a bit more specific on those you feel are still unanswered.

    Best regard,

    Max

  • Temperature analyses for Barry

    Hi Barry,

    You're right.

    IPCC uses a more sound analytical method (linear regression over many years) than just taking short-term spot values for comparison.  The danger is always with "cherry picking" to prove a point, especially when comparing shorter-term with longer-term records.

    IPCC stated that "second half 20th century (redefined to exclude 5 years of cooling from 1951-1955) showed a higher linear trend of entire century (redefined to exclude 5 years of cooling from 1901-1905).

    Sounds like something significant is happening toward the end of the century due to increased CO2 emissions (that is the intended message, of course).

    Now if you turn that short-term/long-term comparison around, you can show that warming slowed down over the course of the 20th century, just as CO2 emissions accelerated.

    Taking a look at the IPCC's cherry-picked "20th Century", starting with 1906, and breaking it into the first 25 years (1906-1930), the first 50 years (1906-1955) and the whole 100-year period, confirms this:
    http://farm3.static.flickr.com/2295/2536244611_d817a54dea ...

    The steepest linear trend was for the first 25 years at 0.11°C/decade, followed by the first 50 years at 0.08°C/decade. The slowest rate of increase was observed over the entire 100-year period, (including the most recent warming period) at 0.07°C/decade.

    So based on this analysis one could paraphrase IPCC with, "the linear warming trend over the first 25 years, 1906-1930 (0.11°C per decade) is 50% higher than that for the entire 100 years, 1906-2006 (0.07°C per decade)".

    Obviously, this analysis is just as phoney as the one made by IPCC, but it just goes to show how figures and graphs can be manipulated to get any story across.

  • Temperature trend lines for Barry Schwarz

    Hi Barry,

    You asked: "Please show in detail how you arrived at the cooling trend line. What's your math?"

    It is precisely the same "math" used by IPCC in AR4 or SPM 2007 in arriving at a 0.74C linear temperature increase over the 100-year period 1906-2005, or the "math" used by IPCC when they state that the "linear warming trend over the last 50 years (0.13C [0.10C to ).16C] per decade) is nearly twice that for the last 100 years".

    Take the data as observed and published (without any smooting, adjusting or averaging) and draw a linear trend line.

    That's all, Barry.  Just observed facts and the same trend analysis used by IPCC.

    Now I'll admit that 100 years tells us more than just a 10-year trend (even a "20th century" that has been shifted by IPCC in somewhat "cherry-picked" fashion in AR4 from 1901-2000 with a linear increase of 0.65C per Hadley to 1906-2005 with a linear increase of 0.74C - by replacing a 1901-1905 cooling trend with a 2001-2005 essentially "flat" trend and somewhat naughtily insinuating with the word "therefore" that this apparent increase was due to adding in "end of the record" warming, rather than by cutting out "start of the record cooling").

    It also tells us more than IPCC's higher "trend over the last 50 years".

    The 30+ year 1910-1944 period that showed a linear trend of +0.53C (with little increase in CO2) probably tells us about the same as the 30+ year 1944-1976 trend of slight cooling (with significantly more increase in CO2) and a little more the shorter 20+ year 1976-1998 linear trand of +0.37C (with a much higher increase in CO2), but together with the most recent 10-year (or, if you prefer 7-year) plateau, they all paint a picture.

    And this picture raises serious doubts about CO2 (with assumed positive feedbacks) causing a "climate sensitivity at 2xCO2 of 3K, which is the whole rationale for the alarming AGW suggestion.

  • Extreme weather events linked to CO2?

    Tuning in kind of late here but a remark by Christopher S. Johnson caught my eye: "Virtually all climatologist who have peer reviewed published findings about Anthropogenic Global Warming have said this:  `While Global Warming cannot be linked directly to an individual weather event because of other factors, the science says that extremes in severity and number of both drought and wet storms are more likely with more CO2 in the atmosphere, than with less'."

    I have not seen such a statement from "virtually all climatologists" but, in any case,  it is a statement of "faith", rather than "science", because it is not backed up by physical observations. Projections for the future based on model studies do not represent any sort of evidence that something is "more" or "less likely", unless they are backed up by physical observations.

    Let's do a quick analysis of the IPCC SPM 2007 take on this (i.e. "the science"):
    http://ipcc-wg1.ucar.edu/wg1/Report/AR4WG1_Print_SPM.pdf

    IPCC makes claims linking AGW with increased droughts, floods, heat waves and other extreme weather events in the late 20th century, claiming a ">66% likelihood" that this  occurred "in some regions", that there is a >50% likelihood that the was a "human contribution" to this (of unassessed magnitude) and then adding the caveat that this is "based on expert opinion rather than attribution studies" (Table SPM.2., p.8).

    A recent report on extreme weather events by Indur M. Goklany shows that these have not increased in actual fact in the late 20th century as claimed by IPCC.
    http://www.globalwarming.org/files/report_20.pdf

    In fact, the report (pp. 48,49) shows that annual death rates from extreme weather events (in both absolute terms and per million) have declined drastically in the latter part of the 20th century rather than increasing.  This includes floods, droughts, extreme temperatures (cold as well as heat) and windstorms (including cyclones, tornadoes, etc.)

    For comparison, the actual record shows there has been no recent increase in US tornado activity due to global warming, but a significant decrease instead, with the worst year for tornado deaths in 1905 when 254 people died and yet there were far fewer people living in the tornado prone areas.
    http://www.spc.noaa.gov/faq/tornado/killers.html

    In its 2007 SPM report, IPCC has also made claims of increased and more intense tropical cyclone activity in the latter part of the 20th century, linking this to AGW (p.8).

    The actual record shows no such increase, but a slight decrease, both in the USA and elsewhere, with most Atlantic hurricanes occurring in the 1940's, not "in the latter part of the 20th century" and no increase in the Pacific.
    http://www.aoml.noaa.gov/hrd/Landsea/deadly/index.html
    http://ff.org/centers/csspp/library/co2 ... 109_15.pdf

    This covers the past and most recent record, which shows that there has been no physically observed increase in extreme weather events in the late 20th century, contrary to the claims by IPCC that these have "likely" occurred (>66%) and that a "human contribution" was "more likely than not" (>50%).

    Now we come to projections for the future, where Christopher states that "virtually all climatologists" say that "extremes in severity and number of both drought and wet storms are more likely with more CO2 in the atmosphere, than with less".

    Let's check again what IPCC ("the science") says:

    Based on an assumed - but not physically substantiated - increase in "heavy precipitation events" of >66% likelihood with a "human contribution" of >50% likelihood, IPCC states that the "likelihood" of future increases "based on projections for the 21st century using SRES scenarios" is "very likely", i.e. >90%.  

    How is it possible to have higher confidence in predictions for the future than in recent events?  This is only possible with a "belief" in the virtual reality of climate models.

    The same "leap of faith" is apparent in the IPCC claim for heat waves, droughts, etc.

    In addition there is the footnote (f) "Magnitude of anthropogenic contributions not assessed. Attribution for these phenomena based on expert judgement rather than formal attribution studies."

    So it appears that IPCC is telling us, "We have only >66% confidence that there is a recent trend, just >50% confidence in an anthropogenic component of some undetermined magnitude (based on "expert opinion" rather than formal attribution studies), but >90% confidence that things will get worse in the future. We have no idea how human activity figures in any of this and anyway it's based on guesswork rather the peer reviewed physical evidence."

    This whole argumentation is so weak that it can be dismissed (as can the lead article on this site by Joseph Romm).

  • Message to Brute (part 2)

    Here's a quote from Roy Spencer that may well be prophetic:

    "If tomorrow the theory of manmade global warming were proved to be a false alarm, one might reasonably expect a collective sigh of relief from everyone. But instead there would be cries of anguish from vested interests. About the only thing that might cause global warming hysteria to end will be a prolonged period of cooling... or at least, very little warming. We have now had at least six years without warming, and no one really knows what the future will bring. And if warming does indeed end, I predict that there will be no announcement from the scientific community that they were wrong. There will simply be silence." --University of Alabama climate scientist Roy Spencer

    Hi Brute,

    Your recent post on Dr. Itoh's new book provides yet another sneak preview of what is happening to the AGW movement as more scientists speak out and people become aware that they have been bamboozled by politicians, "climatologists" turned activists and a sensationalist press.  At the same time, alarming IPCC predictions of record-breaking warming in the early part of the current century have quietly been replaced with actual observations that show no such warming.  

    Are these leading indicators of what is happening to the AGW bandwagon?

    Here's something for us all to think about, as we ponder about the future of mankind and our planet.

    As little as six months to a year ago, the multi-billion dollar global warming bandwagon seemed to be rolling on with strong momentum as politically motivated Oscars and Nobel Prizes were handed out, Bali boondoggles were celebrated, 1,000-page pseudo-scientific IPCC reports (groan!) were published and the media, politicians plus activists were warning us of impending disaster unless we dig deep into our pockets and "ante up" to atone for our carbon footprint.

    But is a wheel slowly coming off and is the bandwagon headed for the ditch?

    At the same time that alarmists are shouting "tipping point" and "imminent inundation from 6 meter waves", the thermometers out there (even the ones next to asphalt parking lots and AC exhausts) are telling us something else: global warming has stopped!  Ouch!

    This is true if one looks at the past 10 years (1998-2008).  It is also true if one looks at the past seven years only, starting in 2001, rather than starting the trend with the arguably all-time warmest year ENSO of 1998.  

    This year (2008) has started off cooler than normal and the WMO predicts it will probably continue to remain cool.

    Of course there are howls of denial and proclamations such as "we are now at a global temperature not experienced in human civilization" and "ten (or seven) `cherry-picked' years do not make a new trend", but the fact remains: global warming has stopped (for now).

    Everyone realizes that 10 years is too short a period to establish a long-term climate trend, but IPCC Chairman, Rajendra Pachauri, is apparently concerned.  In a recent interview, he is quoted as saying he would "look into the apparent temperature plateau so far this century."

    "One would really have to see on the basis of some analysis what this really represents," he told Reuters, adding "are there natural factors compensating?"  (Or is the link between "global temperature" and increased CO2 concentration as the models predicted just not working out in actual fact?)  Pachauri also added that he hoped the current plateau would not lead people into believing that AGW was "hogwash".

    Hogwash or not, it is too early to tell what will really happen.

    Will the warming temperature trend continue to level off and "plateau" or even reverse itself to a longer-term cooling trend?

    But whatever happens, it does not bode well for the global warming doomsayers when people see TV reports from all over the northern hemisphere showing colder than normal weather at the same time we see an apparent increase in tornadoes and floods. These become increasingly difficult to "pitch" as effects of AGW when thermometers tell us it is no longer warming.

    How many more years of flat (or cooling) temperature trends will it take for the bandwagon to end up in the ditch?  

    Will this derail the whole multibillion dollar IPCC gravy train?

    We shall see.

  • Global warming stopped in 1998?

    Hi Black Wallaby,

    Looks like there are still a few folks out there that have a hard time accepting observed facts (ex. Hadley surface temperature anomaly record).

    These facts show that it has warmed over the past 150 years in several multidecadal warming/cooling cycles and an underlying warming trend of 0.6 to 0.7C per century.

    Notable warming cycles were from 1858-1879, 1910-1944, 1976-1998.  In between these we had cycles of slight cooling plus the most recent plateau.

    The cycle from 1976-1998 is the "poster cycle" for AGW proponents, because there was a rapid increase in temperature at the same time as human CO2 emissions and atmospheric CO2 concentrations rose.  Other cycles do not present a very convincing correlation.

    This site starts out discussing the thesis "Global warming stopped in 1998".  

    There is no doubt that the observed facts (from all four records) show that this is precisely what has happened for now.  That is not to say that global warming may not start again some time in the future, but for now all records show that it has either flattened out or reversed slightly since 1998 (or 2001, if one prefers not to start with the all-time record ENSO year).

    The attached graphs show pretty clearly what is going on.

  • A message for jbullfrog

    Hi jbullfrog,

    Since you are apparently "frustrated" because no one has specifically responded to all the points in your earlier post, here goes.

    1.    "All the folks on here who are trying to rely on the Hadley data as a counterargument to AGW seem to feel that "smoothing" data is "cheating." Yet they then talk about a "cooling trend" in the last 8 years."

    No one says "smoothing data" is "cheating".  It is just one way of looking at data.  The more obvious way to look at temperature data is the way that IPCC does this.  Take the raw data without any smoothing over various periods and draw the linear rate of change over this period.  And this approach shows clearly that global warming has stopped since around 1998, or 2001, if you prefer not to start with the previously (TAR) much-ballyhooed record year 1998.

    2.    "Listen, folks, smoothing is simply a graphical representation of the concept of a trend. If you say there is no more global warming because of a downward trend, clearly you are examining small samples of less than a decade at a time. Or in your own words, you would like to look year-by-year. That's fine, let's do that. If we take a one year sample, we may find that, say, 2004 was cooler than 2003. If you implement a very fundamental and uncomplicated type of reasoning you might predict that 2005 would continue this "trend". But this was not the case. It was significantly warmer. So is the "trend" now towards "warmer?" Because the next year reversed again, and 2006 was a lot cooler, and 2007 a bit cooler still."
    3.   
    Nothing new added here, except a bunch of blah-blah.  The current linear trend shows a plateau (since 1998) and slight cooling (since 2001).  Just the plain old facts without any rationalizations or "smoke and mirrors".

    4.    "In other words, if you go year-by-year, then yes, we have a one year cooling "trend" from 2006-2007. If you go back another year, we have a two year streak of one-year cooling "trends." If you go back another year that streak is over, so your argument is dead. By your own year-by-year logic, we have only been cooling for two years... "

    More blah blah.  Do yourself a favor and really look at the data.  You will see that the current linear trend is flat to slight cooling, and that has been the case for around 10 years.  This is admittedly a short period (and no one is claiming that this is the beginning of a longer trend).  Yet the IPCC's "poster period" of warming from 1976 to 1998 was only a bit more than twice as long as the current flat to cooling period, so the current period is really not that insignificant in comparison.

    5.    "...UNLESS you want to redefine "trend" to help us understand your theory, which is the "crime" of which you're accusing hundreds of scientists. Which will it be? Are you going to be scientific about this, or just quote the dictionary as if their definition of the word climate had ANYTHING to do with the true essence of this debate about rising temperatures and the credibility of the scientific community. No, you're stuck with two years of cooling, or else you are cheating, just like all scientists everywhere who ever say anything that sounds like it might not be any fun."

    This one hardly merits a response: "two years of cooling, or else you are cheating".  Look at the data, rather than making childish remarks about "cheating".

    6.    "I can't stand this juvenille approach. If you're going to argue a scientific theory, you have to use scientific data to support your argument. If you're going to use scientific data to support your argument, you have to use it as part of a legitimate and consistent scientific approach."

    "Juvenile approach?"  Hmmm...

    7.    "NiceGuy, you're a better man than me. (Have I already said this?) You continue to prove it is possible to argue your position with consistency, accuracy and depth without getting visibly pissed off. I just can't help getting mad. I feel as if the denial folks on here think I wouldn't listen if there were a serious scientific counterargument being presented, and as if they think they are presenting one. It's like watching poison at work as they co-opt useful terms and positive traits and use them for their own irresponsible purposes. Like when they mock the fact that you make your arguments with civility, as if that lends their argument credibility. Like when they take a term like cherry-picking, a term representing a concept used by the scientific community to identify an illegitimate argument, and apply it haphazardly and erroneously to any data they can't understand."

    I will agree that MNG is a very polite individual that does not resort to name calling, fits of rage or other juvenile emotional outbursts in his discussions (I have had several interesting exchanges with him, myself, and find his manners and approach to an adult dialogue impeccable).  In MHO he is sometimes a bit too naïve when it comes to believing all the climate hysteria that is out there and he sometimes tends to drift from the main issues at hand, but I have learned a few things from him and agree that he is a good representative for the AGW viewpoint in the ongoing debate.
    To the second part: "Like when they take a term like cherry-picking, a term representing a concept used by the scientific community to identify an illegitimate argument, and apply it haphazardly and erroneously to any data they can't understand", I would say that this cuts both ways.  IPCC itself, not to mention some of the more rabid AGW alarmists, have used "cherry picked" data, have ignored data that do not support the AGW message and have misleadingly equated their personal viewpoint with that of the "scientific community" (ignoring the scientists who do not support this point of view).  

    8.    "So frustrating."

    Been gone for a while and just read your semicoherent babbling: "Also, manacker, in an earlier comment you claim that you are not a "conspiracy theorist" and then immediately launch in to a detailed conspiracy theory surrounding the political agenda of the UN, how the IPCC is primarily concerned with self preservation, how thousands of scientists are focused on grants first and honesty second, how scientific journals are biased toward AGW just to increase their circulation.  Your writing defines 'delusional', no different to moon landing denial, evolution denial, or 9/11 was an inside job."

    No "conspiracy theory" required.  Just human nature, self-interest, agenda driven pseudo-science and several billions of dollars at work, with the jackpot in sight of hundreds of billions of dollars in carbon taxes and cap and trade schemes to be shuffled around by politicians and bureaucrats, with a few already wealthy and powerful individuals getting richer at the expense on everyone else (particularly those at the bottom of the pyramid today).

  • A correction of Peter's statement

    Hi Peter,

    Been away from this site for a few days.

    You wrote:

    'You write " Applying Stefan-Boltzmann: dT = 5.78 / [ 4 * 5.6705E-08 * (288.16^3) ]

    I seem to rememeber you posting a similar calculation on another forum and coming up with a figure 0.7 deg C for a doubling of CO2 from its pre-industrial level.'

    Duh! Your memory is a bit confused.

    2 X CO2 (according to Arrhenius, Stefan-Boltzmann and Myre et al [IPCC]) gives us an increase of 0.7C (actually 0.683C, to be more exact).

    Going from today's 380 ppmv to the absolute maximum-maximum worst case ever when all fossil fuels are gone gets us to around 1100 ppmv and 1.1C above today's temperature.

    Since the assumed "positive feedbacks" required to multiply this dT by over 4X are unproven and have even been challenged based on actual observations (water vapor/clouds), we can dismiss them for now and stay with the greenhouse theory "as is" for CO2 (and other GHGs) alone.

    Got it?

    It's really quite simple, once you look at the physical reality of the observed data out there(rather than the virtual reality of the GIGO climate models).

    Hey Katakanadian

    You wrote: "It may always be part of the energy mix but you can't get a few hundred nuclear plants built in the next five years which is when I expect the real wakeup call to the oil crisis to hit."

    Who knows if your pessimistic prediction is right or not?

    If the "greenies" keep opposing new nuclear plants (and the authorities are stupid enough to let this happen), we may indeed get into a "crunch" some time in the future (not the "next five years", but a few years later).

    The smart countries (like France) will become major power exporters, while the less astute ones (run by "greenies") like Germany will be the net losers.

    Many European countries are already considering quietly removing the mandated ban on nuclear energy.  

    What the USA will do is still an open question, as long as you have the environmental activist groups with their lawyers trying to stop any new nuclear plants due to "Three Mile Island" and "Chernobyl" hysteria.

    But I am a bit more optimistic on the future than you appear to be.

    Of course, we will both tell each other that we are being "realistic", while the other is not so, but history shows that things usually get resolved through common sense solutions before there is a major disaster.

    So cheer up and don't fall into the trap of relying on major taxes to solve any problems.  They don't.

    "What are the estimated rates of conversion to non-fossil energy sources in this model (if included at all) and are we really converting that quickly? I suspect not."

    Your suspicion may be flawed.

    History has shown us that we shift priorities as new challenges and opportunities arise, so there is no reason to believe that this history will not repeat itself.

    The "green" opposition to nuclear energy is already starting to crumble as it becomes clear that this is the most viable solution to the possibility of decreasing fossil fuel supplies.

    Look around you.  That is what is happening.

  • CO2 in atmosphere

    Hi Davkel

    The "Climate Myths" article you cited states:

    "About 40% of the extra CO2 entering the atmosphere due to human activity is being absorbed by natural carbon sinks, mostly by the oceans.  The rest is boosting levels of CO2 in the atmosphere."

    Let's do a quick "sanity check" on this statement.

    Human CO2 emissions are equal to 7.5 GtC per year.

    This equals 27.5 GtCO2 per year (as CO2).

    The troposphere represents a mass of 3,750,000 Gt.

    So this annual emission would represent an increased concentration of 7.3 ppm(mass).

    This equals 4.8 ppmv, after adjusting for the relative MW of CO2 and the atmosphere.

    But the measured increase is only 1.9 ppmv.

    This means that 1.9 / 4.8 or 39% stays in the atmosphere, and 61% (rather than 40%) goes somewhere else.

    So the article is exaggerating the impact of human CO2 emissions on the atmosphere by slightly over 50% (which is actually not too bad for that site).

    Most of this is absorbed by the oceans and the rest "disappears" elsewhere.

    Here's an interesting article that talks about the "half-life" of atmospheric CO2.

  • ClimateCriminal makes sense on conservation


    ClimateCriminal wrote some wise words on 7 May:

    "Anybody who thinks that limited resources means it's OK to plunder natural resources right up to the wire, without developing renewable alternative high efficiency generation and other technologies and better insulation ready to switch over to renewables, is heading for a hard landing and fooling themselves."

    All of this makes good sense.  Saving energy where possible, reducing dependency on imported oil from politically unstable regions, eliminating waste, replacing low efficiency power plants with newer high-efficiency plants, including renewables (where this makes economic sense), building new nuclear generation plants, growing motor fuel (as Brazil is already doing successfully with sugar cane ethanol), etc.

    40% of natural gas and 25% of petroleum go into higher added value non-fuel end uses (petrochemicals, plastics, fertilizers, etc) today.  This percentage will undoubtedly increase in the future.  Even coal will eventually become too scarce to just burn and it will be used for higher added value end uses.  South Africa (SASOL) already does this.

    And there is no practical limit of nuclear fuel as uranium available on this planet, just using today's fission technology, not to mention future "fast breeder" reactors that use less than 2% of the uranium used today per KWH generated.

    And then there is the long-term possibility of nuclear fusion if and when fuel for fission ever starts to run short several hundreds of years from now.

    This does not require that we "tax fossil-fuels and use those taxes to encourage develop[ment of] renewable [and other fossil fuel independent] technologies" as CC suggests.

    These developments will all occur because they make sense.  

    But all of this has nothing to do with taxing carbon to mitigate the the imaginary "threat from AGW", which does not make any sense at all.

  • Worst-worst theoretical warming from AGW

    Andrew Dessler's lead article pointed toward some interesting questions with regard to a suggested disastrous warming caused by CO2 generated from fossil fuel combustion.

    We have seen that burning all the fossil fuel available in this world would theoretically emit 1150 GtC, and that this would get us to around 670 ppm CO2 in the atmosphere, which would add around 0.6C warming from today, according to the radiative forcing for CO2 used by IPCC (and the greenhouse theory). [The study cited by Andrew limited CO2 to around 500 ppmv, so the warming would be a bit less.]

    This is based on the assumptions that (a) increased atmospheric CO2 concentrations are caused by human CO2 emissions and (b) the currently observed ratio of CO2 emission to change in atmospheric CO2 concentration will continue into the future (7.5 GtC emission cause an increase in atmospheric CO2 of 1.9 ppmv); at this observed ratio, only around 39% of the emissions remain in the atmosphere.

    IPCC SPM 2007 (p.16) states:
    "Climate-carbon cycle coupling is expected to add carbon dioxide to the atmosphere as the climate system warms, but the magnitude of this feedback is uncertain."

    The speculated (but admittedly "uncertain") positive feedback from "climate-carbon cycle coupling" would suggest in theory that a higher percentage of the CO2 emissions would remain in the atmosphere than has been physically observed to date (only around 39% remain in the atmosphere, as stated above).  A major portion is absorbed by the oceans, which contain 50 times as much CO2 as the atmosphere.

    IPCC goes on to say: Based on the current "understanding of climate-carbon cycle feedback, model studies suggest" that "to stabilize at 1000 ppm, this feedback could require that cumulative emissions be reduced from a model average of approximately 1415 GtC to approximately 1100 GtC".

    There is not enough carbon in all the fossils fuels in this world to ever reach a "model average of 1415 GtC", so the models are obviously wrong in their base assumption (the point made by Andrew Dessler's lead article).

    If we were to assume that (as a result of the hypothetical "climate-carbon cycle feedback") 100% of the CO2 emitted into the atmosphere remains in the atmosphere indefinitely, the total CO2 from burning all fossil fuels in this world would increase CO2 by 740 ppmv (from today's 380 ppmv to a maximum imaginable theoretically possible long-term concentration of 1120 ppmv).

    And there is another "unexplained" loss.  Not only does the ocean absorb a significant portion of the emitted CO2 (estimated to be around 1/3 of the amount emitted), but an equivalent portion apparently "disappears" elsewhere.

    The "e-fold lifetime" of CO2 in the atmosphere has been calculated to be around 55 years (the relationship is logarithmic and the half-life is 38 years).
    http://www.john-daly.com/carbon.htm

    The cited study also shows how IPCC models have made unrealistic assumptions concerning the amount of carbon theoretically available (Andrew's lead article) and have ignored the limited lifetime of CO2 in the atmosphere.

    But let's take the most absurd worst-worst case imaginable and apply the greenhouse theory (plus the RF estimate for CO2 used by IPCC);

    All the world's fossil fuels would generate 1,150 GtC.

    If this all stayed in the atmosphere indefinitely (i.e. no absorption by the oceans and an eternal lifetime of CO2 in the atmosphere), the maximum future CO2 concentration ever reachable is around 1120 ppmv.

    Using the greenhouse theory: ln (1120 / 380) = 1.08

    Applying IPCC's forcing factor for CO2: 5.35 * 1.08 = 5.78 W / m^2 (radiative forcing of increasing CO2 from 380 to 1120 ppmv).

    Applying Stefan-Boltzmann: dT = 5.78 / [ 4 * 5.6705E-08 * (288.16^3) ]
    = 1.1K (equals 1.1C)

    So the worst-worst ever imaginable theoretically possible warming from burning all of the world's entire fossil fuels results in a global temperature increase of slightly over 1 degree C.

    This does not sound like a disaster scenario to me, even if James E. Hansen and Al Gore see it that way.

  • Fossil fuel reserves and temperatures

    Further to the earlier post on fossil fuel reserves and atmospheric CO2.

    If we assume that the combustion of all fossil fuel reserves on Earth today will increase atmospheric CO2 from today's 380 ppmv to a level of 670 ppmv, what does this mean as far as temperatures are concerned?

    Using IPCC's estimated radiative forcing (RF) of 1.66 W/m^2 from the increased CO2 concentration from pre-industrial values of 280 ppmv in 1750 to values of 379 ppmv in 2006, we arrive at an additional RF from 2006 to the future date when all fossil fuels are gone equal to 3.05 W/m^2 (the relationship is logarithmic).

    This means that the burning of all the fossil fuels available on this planet will cause an additional temperature increase (from today until that time) of 0.56C.

    Even Andrew Dessler will have to agree that this is truly insignificant.

    Let's all go back to sleep and forget about this non-problem.

    Or better yet, let's forget about this non-problem and start to concentrate on solving some real problems that exist out there.

  • Fossil fuel reserves and CO2

    Andrew Dessler's lead article raises some interesting questions.

    There are a lot of estimates out there, but the Oil + Gas Journal estimates:

    Proven oil reserves word-wide are 157 billion tons
    Current use is 3.5 billion tons/year
    So at today's level of usage, there are 45 years
    This number includes a portion of the Canadian tar sands currently under development, but not the worldwide oil shale deposits (USA and elsewhere); these non-included sources are huge and could increase reserves by an additional 300-400 billion tons.
    1 ton of oil generates 0.85 tons of C (as CO2), and around 75% of the oil is used as fuel, so including oil shale the total oil reserves would generate around 290 GtC.

    Proven natural gas reserves are 176,000 billion cubic meters
    Current use is 2,800 billion cubic meters/year
    So at today's level of usage, there are 62 years
    1 cubic meter of natural gas generates 0.55 kg C (as CO2), and around 60% of the natural gas is used as fuel, so we have a total CO2 generation of around 60 GtC.

    Coal reserves (Wikipedia) are 909 billion tons
    Current use is 6.2 billion tons/year
    So at today's level of usage, there are 147 years
    1 ton of coal generates around 0.91 ton of C (as CO2), and around 95% all of the coal is used as fuel, so the total coal reserves would generate around 800 GtC.

    All together this represents around 1,150 GtC (as CO2).

    We are currently generating 7.5 GtC/year; at the same time atmospheric CO2 is increasing by 1.9 ppmv/year.   So, assuming the same ratio stays in the atmosphere, the world's total supply of fossil fuels would increase atmospheric CO2 by around 290 ppmv, from today's 380 ppmv to 670 ppmv.

    So it appears that the 500 ppmv, which Andrew Dessler quoted from Professor Rutledge's study, could be a bit low (possibly the oil shale was not considered in the reserves), but it is not that far off.

    How quickly this would occur depends on how quickly we switch from fossil fuels to other sources, such as nuclear.

    It also depends on the discovery of new fossil fuel deposits and the possible development of totally new technologies.

    The estimates of uranium fuel reserves for nuclear power generation vary greatly, and most reported figures state the quantities, which are currently recoverable at a given price. Most estimates agree, however, that there is enough recoverable uranium available to last well over 100 years (a recent German study says 200 years), even if a major portion of new electrical power generation is from nuclear.

    In the future there will be new nuclear technologies, as well, such as the "fast breeder" reactors, nuclear fusion, etc.

  • Check the thermometers, Pangolin

    Hi Pangolin,

    Of course the warming has stopped (for now).  All you have to do is look at the official records.

    There has been no warming since 1998 (or 2001, if you prefer not to start with the all-time record ENSO year, 1998).

    You sort of went into an emotional rant with, "If you want to believe Christian-fundie-whacko, weatherman, Anthony Watts and the mushrooms growing in his shade go right ahead. Just don't pretend it's science."

    No, Pangolin, I believe the thermometers out there (the same ones that were used a few years ago to sell us the alarming AGW storyline).

    To deny the current flat to slight cooling trend is just sticking your head in the sand.  Even Dr. Pachauri has said he would look into the reasons for this "plateau", adding that he hoped people would not use this to conclude that AGW is "hogwash".

    And nobody (including you, me or the fancy computer models) knows if it is going to continue cooling for a while, or start warming again.

    Isn't that exciting?  Isn't nature grand?

    Regards,

  • A bad time for AGW "believers"

    The 21st century has not started out well for "believers" in the AGW hypothesis, or for the politicians and bureaucrats that are hoping to use the AGW scare to implement hundreds of billions of dollars in carbon taxes or cap and trade schemes.

    The ink has barely dried on the IPCC's 1,000+ page AR4 WG1 report and it is already way out of date.

    While AGW alarmists are predicting model-generated imminent "tipping points" with disastrous consequences, the thermometers out there (even the ones next to AC exhausts or asphalt parking lots) are telling us a different story: global warming has stopped.

    Global land and sea surface temperatures have reversed the late 20th century warming trend and have cooled slightly since around 1998. The satellite temperature record of the troposphere shows the same slight cooling trend.

    Ocean temperature measurements from Argo robots show that the ocean has cooled significantly since 2003, when measurements started, essentially reversing the warming measured at spot locations over the previous 50 years.  Since the ocean holds 1,000 times more heat than the atmosphere, this is a sign of major cooling of our planet.

    The cold winter 2007/2008, that did not want to end, has broken records all over the world, and the WMO tells us that 2008 will continue to be colder than normal, as ENSO is in a cool cycle and Solar Cycle 24 starts out very slowly.

    And during all this cooling, human CO2 emissions are continuing at record rates, as the economies of new giants, such as China and India are booming, European emissions are continuing to rise and Americans are still driving around in their gas-guzzling SUVs.

    To make matters even worse for the AGW alarmists, there are increasing numbers of scientists and journalists that are daring to take the "non-PC" stand of questioning the science underpinning the AGW scare.  One such article by a top climate scientist:
    http://www.energytribune.com/articles.cfm?aid=828

    And, in this age of instant information, AGW skeptical sites like ClimateAudit, WattsUpWithThat, etc. are drawing the public's attention to weak points and errors in the science and data, which support the AGW hypothesis.

    No wonder the AGW alarmist sites like RealClimate, Grist, etc. are getting worried and are hoping to keep the scare going with articles (like the lead article here by Andrew Dessler) denying what the thermometers are telling us ("it's just a speed bump in the road") or diverting our attention with claims of overwhelming "consensus" in the "peer reviewed scientific community" for AGW, etc.

    The politicians are also getting concerned that the multibillion-dollar boondoggle may implode before it really gets off the ground and are shouting that "the debate is over" and "we must act now to save the planet before it's too late".

    Before it is too late, indeed...  Pop!

  • Do GHGs drive warming?

    Hi TP,

    You wrote, "But everyone agrees climate change (historically) has to do with GHGs. At least partially."

    Not really.

    There is no valid reason to believe that climate change (i.e. global warming) has had anything to do with (anthropogenic) GHGs in the past.  The record shows warming with no added CO2, cooling with lots of added CO2 and sometimes warming with added CO2.  

    Take your pick, but it is certainly not true that "everyone agrees climate change (historically) has to do with GHGs".

    Hi TP,

    You wisely said, "If ya think climate change revolves around just CO2 and fuel, then you're very wrong."

    Yep, An if ya think climate change (a.k.a. global warming) revolves around CO2 at all, "then you're very wrong", as the record shows.

    So why put in a "carbon tax" to "solve" the problem?

  • Correlation vs. causation (for MNG)

    Hi MNG,

    As we both know, correlation between two variables does not demonstrate causation.

    An example would be the correlation between rising temperatures from 1976 to 1998 and rising global consumption of hamburgers over this same period.

    It is, however, obvious that the LACK of correlation between two variables does clearly demonstrate the LACK of causation.

    In the case of atmospheric CO2 and global temperature, the observed record shows an apparent correlation for the period 1976 to 1998, which, as explained above, does not demonstrate a causation.  

    Yet this apparent correlation is used to support the AGW hypothesis, with the nonsensical rationale that "it must be so, since we can find no other explanation".

    The problem is that no other periods in the temperature and CO2 record since 1850 show such a correlation.

    The lack of such a correlation is a clear indication that the suggested causation is falsified.

    The attached graphs demonstrate this very clearly.
    http://flickr.com/photos/6959/2469181025/sizes/o/

    In the interest of enlightening you as well as other Grist readers (in a nice way, of course), I would (nicely) suggest that these readers (plus yourself) check out these data and then come to a rational decision regarding CO2/temperature causality.

    Hoping to have been nice in helping to enlighten you, MNG, plus other esteemed Grist readers with some real data (as opposed to computer-generated hype or "statements of faith").

  • Message for MisterNiceGuy

    Hi MisterNiceGuy,

    You have argued for "caution" rather than "certainty":
    "That desire for certainty is good, but it's very important that we realize we don't need to be anywhere close to "sure" about a potentially bad outcome to justify caution."

    This is the classical politicians' argument for justifying an unpleasant political agenda through fear.

    US citizens were told by a group of politicians that weapons of mass destruction in the hands of a Middle Eastern tinhorn dictator constituted an imminent threat to their security.  The specter of a "mushroom cloud smoking gun" was evoked unless immediate action is taken (a preemptive strike that ended up becoming a dragged out war without end costing trillions of dollars and many thousand lives).  The "intelligence" information concerning the WMD turned out to be incorrect, but the war could still have been justified, if one applies MNG's "caution rather than certainty" principle.

    The world's citizens are now being told by another group of politicians that their emissions of CO2 constitute an imminent threat to the environment, other species and even humanity itself.  The specter of "6 meter waves swallowing New York City" is being evoked unless immediate action is taken (the implementation of draconian carbon taxes or cap and trade schemes that will plunge the world into a major depression and make a few already wealthy individuals richer and give politicians and bureaucrats trillions of dollars to shuffle around).  Even if the "scientific basis" for potentially disastrous anthropogenic greenhouse warming turns out to have been incorrect, MNG argues that "I don't need to be `sure' that CO2 and other human-caused GHG's are accelerating the rate of global warming in order to justify caution."

    My (very nice) precautionary advice to MNG:  
    ·    watch out for politicians (or environmental activists or AGW snake oil salesmen) that are using fear mongering to frighten the public into accepting an unpleasant political agenda
    ·    be skeptical of their claims and make absolutely sure that the "imminent disaster" projections they use to generate this fear are based on sound science and not agenda-driven pseudoscience.

  • No evidence of early GHG increase

    Sorry, TP.

    Check it out yourself and you will see that IPCC does not show any major increases in other GHGs over these early periods.

    The data they show on CO2 would indicate an increase of about 2 ppmv over the 1858 to 1879 warming period and about 15 ppmv over the 1910-1944 warming period.

    "Off the top of your head" is nice, but quantified information supported by hard data is a lot better. The late 19th century increase in coal use compared to today's SUVs, etc.?  Gimme a break, TP.

  • A picture is worth...

    In his discussion with Black Wallaby, MisterNiceGuy has given us some links to "smoothed out" temperature records, in order to demonstrate to Grist readers that the observed "plateau" in global warming over the past decade is actually just an "anomaly" (in the anomaly) - to put it nicely.

    Other contributors to this site have questioned whether or not global warming has stopped.  Then there are those (i.e. jbullfrog) that have drawn our attention to Hadley comments about the effects of their methods of data smoothing, while others (i.e. MichaelTobis) defend "climatology" without directly addressing the CO2/temperature causality issue or the current flat trend.  

    Some of these contributors (jabailo, Black Wallaby, myself, etc.) have called attention to the cyclical nature of the temperature record, and commented on the lack of clear observed evidence of CO2/temperature causality.

    To make these cycles easier to visualize I've plotted them.

    Below are links to these data showing the overall linear trends, plus the linear trends during the various multi-decadal warming and cooling cycles observed since the record started.

    The seven multi-decadal warming and cooling cycles since 1850
    http://flickr.com/photos/6959/2465302088/sizes/o/  
    We can also see the correlation over these cycles between CO2 increase and temperature rise:
    1850-1858: negligible increase in CO2
    1858-1879: 2 ppmv increase in CO2
    1879-1910: 6 ppmv increase in CO2
    1910-1944: 15 ppmv
    1944-1976: 23 ppmv
    1976-1998: 33 ppmv
    1998-2008: 20 ppmv

    What can be seen from these data is that
    ·    There has been an overall warming trend since 1850
    ·    There have been three multi-decadal cycles of warming (and four cycles of cooling) since 1850, when the record started
    ·    Warming over the most recent cycle (1976-1998) is not at all unusual, when compared to warming over two earlier cycles (1858-1879 and 1910-1944), when there was very little impact of CO2 or other GHGs

    As has been pointed out earlier on this site, there is an inconsistency in the logic of the IPCC in stating its case for AGW.  The warming of the most recent cycle is attributed (by IPCC) to CO2 (and other anthropogenic GHGs) because models show that "no other explanation can be found", yet no explanation has been found for the other two warming periods (when there was very little or no increase in CO2).  

    In other words, the logic goes something like this:

    1.    We cannot explain what caused the late 19th century and early 20th century warming.
    2.    We know that CO2 caused the late 20th century warming.
    3.    Why?
    4.    Because nothing else explains it.

    And, one could add:  we also do not know what has caused the current plus mid-20th century flat to cooling trends.  

    The clear "take home" is that there are multi-decadal cycles of climate change, that have very little to do with CO2 (or other man-made GHGs), that are ignored by IPCC, because they cannot be explained by AGW.

    Hoping to have helped by plotting the Hadley data in graphs that show the various warming/cooling cycles and linear trends (rather than just tables of data), so that Grist readers and contributors can more easily visualize the data and make up their own minds.

  • MNG (nicely) gets it wrong on CO2

    Other Grist contributors may have noted an apparent strange confusion on the part of a very nice contributor to this site when confronted with an inconvenient, yet unexplained, warming period that could not have been caused by CO2.

    When it was pointed out that during the late 19th century warming cycle, temperature records show a linear increase of temperature of around 0.38C over a 21-year period 1858-1879 (very close to the 0.37C linear increase observed during the 22-year period 1976-1998), during which time frame there was essentially no increase in atmospheric CO2 concentration (only around 2 ppm), so that the warming could hardly have been caused by CO2 (as is being suggested by default for the late 20th century period, where CO2 concentrations rose by 33 ppmv).

    You (very nicely) pointed out that there was an atmospheric CO2 concentration of 280 ppmv in 1850 (based on IPCC reports citing ice core data), so that there was not "essentially no CO2".  

    May I very nicely ask you what that has to do with the earlier conclusion that CO2 could hardly have had anything to do with the late 19th century warming cycle, as there was "essentially no" increase in CO2 concentration over this warming period?

    This also begs the second question, which is: if the causes for the early warming cycle cannot be explained, how can we be sure that the same "unexplained" factors, rather than CO2, have not also caused the late 20th century warming.

    Hope I asked this nicely enough.

  • The IPCC poster years

    Message to Bob Tisdale

    Thanks for your info.

    You are 100% right.  There are many explanations for the 1976-1998 warming cycle beside increased CO2.  In fact, CO2 has only been incriminated by IPCC because "model studies" supposedly show that there is no other explanation".

    But, as you say, these model studies have failed to consider the factors you mentioned (ENSO, PDO and AMO) and they do not mention the solar cycle and downgrade TSI impact to less than 1/10th of CO2

    For me the weakest part of the IPCC argument for AGW causality is this:  they admit they cannot explain the early 20th century warming cycle when there was very little CO2 (and they do not even mention the late 19th century warming cycle, when there was essentially no CO2), yet they attribute the late 20th century warming to CO2 (and other GHGs) because models indicate that "no other explanation can be found".

    The logic goes like this
    1.    We cannot explain what caused early 20th century (and late 19th century) warming
    2.    We know that CO2 caused late 20th century warming
    3.    Why?
    4.    Because nothing else explains it besides CO2

    To me this is a fatal flaw in the causality argument.

  • Confused despite "background in science"


    Hi Tasermons Partner,

    Looks like you still "believe" in the AGW theory (or hypothesis), even though the temperature / CO2 record does not give much support for this theory, with the notable exception of the period from 1976 to 1998, when the two curves coincidentally happened to correlate.

    The latest (1998-2008) flat to cooling period with record CO2 emissions does not lend much confidence in the robustness of the CO2/temperature causation.

    The fact that earlier warming periods cannot be explained by AGW, yet the 1976-1998 period is attributed to AGW "because no other explanation can be found" is a serious flaw in the whole rationale for AGW caused warming.

    Sorry, TP, the hypothesis is starting to fall apart and people all over the world are starting to realize it, too.

    Believe me, TP, his whole AGW hysteria will be buried on the trash heap of history in a few more years and you can move on to a new "imminent disaster" (caused by evil mankind, of course).

    What'll it be next time?

  • Examining climate change over decades

    In his lead article, Andrew Dessler advises us: "Climate change must be examined over decades, not years."

    This is sound advice.  Fortunately, we have a record (Hadley) that goes back to 1850, so that gives us plenty of decades to look at.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    If we follow Andrew's advice, we see that there has been several multidecadal cycles of warming and cooling over the record, with an underlying warming trend of slightly under 1C over the entire 150+ year record.

    There were three warming and four cooling cycles:
    1850-1858 (8 years), -0.091C/decade; -0.07C cooling over period (part of an earlier cycle?)
    1858-1879 (22 years), +0.172C/decade, +0.38C warming over period
    1879-1910 (31 years), -0.074C/decade; -0.23C cooling over period
    1910-1944 (35 years), +0.150C/decade; +0.53C warming over period
    1944-1976 (33 years), -0.013C/decade; -0.04C cooling over period
    1976-1998 (23 years), +0.159C/decade; +0.37C warming over period
    1998-2008 (10 years) -0.021C/decade; -0.02C cooling over period (beginning of a cooling cycle?)

    Over these cycles we had the following increase in atmospheric CO2 concentrations:
    1850-1858, <1 ppmv increase over period
    1858-1879, 2 ppmv
    1870-1910, 6 ppmv
    1910-1944, 15 ppmv
    1944-1976, 23 ppmv
    1976-1998, 33 ppmv
    1998-2008, 20 ppmv

    So we have the most recent warming cycle (1976-1998), which shows warming with increased CO2.

    The early 20th century warming cycle shows even more warming with little increase in CO2, while the late 19th century warming cycle shows warming and essentially no increase in CO2.

    The mid-century cooling cycle shows slight cooling with significant increase in CO2, while the latest decade (beginning of a new cycle?) shows slight cooling with a very high rate of increase in CO2.

    The only cycle that really fits the AGW theory is the period 1976-1998.  This has been the AGW "poster" period.  It has been used to "sell" the story.

    No wonder that earlier warming and cooling cycles that do not fit the AGW theory are not discussed by IPCC.

    And no wonder AGW aficionados (like Andrew) are scrambling to try to keep the image of continued warming alive, even when the record shows it has stopped.

  • Andrew's imaginary monster

    In claiming that global warming has not really stopped ("it just looks that way"), Andrew Dessler wrote: "but like an axe-wielding psycho from a cheap horror flick, it just keeps coming back."

    A good analogy (Andrew likes these).

    It is indeed an imaginary "axe wielding psycho from a cheap horror flick", rather than a reality. Like you tell your kids, "Don't be frightened - it's only a movie." The "axe wielding psycho" only exists in the virtual world of computer models.

    But Andrew gives us some sound advice: "At times like this, it is always useful to look at the data."

    Now Andrew has not really shown you the "data".  He has shown you a curve based on a "smoothing" of the data.  But all those thermometers out there do provide the data to look at, and they tell a different story than Andrew's curve.

    They tell us that the warming stopped in 1998.  Or if you prefer (since 1998 was the all-time high ENSO year), it has stopped since 2001.  All four temperature records agree: three (Hadley, UAH, RSS) show a cooling trend, while GISS, the odd man out, shows a flat trend).

    And 2008 has started off even cooler, with the WMO predicting that the cooler temperature will continue throughout the year.

    Denying an inconvenient fact does not make it go away, Andrew.  Global warming has stopped (for now).

    What will happen in the future is anyone's guess.  The IPCC forecast of 0.2C increase per decade (for the first two decades of the 21st century) has died quietly, with eight slightly cooling years so far.

    And the suggested link between CO2 and temperature has become much more tenuous that during the AGW heyday period 1976-1998.

    So while AGW aficionados like Andrew are scrambling desperately to fog up the facts and keep the AGW story alive, those thermometers out there (even the ones next to AC exhausts and asphalt parking lots) are telling us: global warming has stopped.

    And, as the old saying goes, "You can fool some of the people all of the time and all of the people some of the time, but you can't fool all the people all of the time" (as the blogger response to Andrew's article on this site) shows.

  • Has global warming stopped (for now)?

    Hi MNG,

    You wrote: "The red trend line, which is a 5 year average, seems to be just starting to level off at its rightmost end, which is roughly 2 years ago."

    Unfortunately, you cannot use a 5-year trailing average to determine what has happened over the last years of a trend.

    If you look at the Hadley data, we see that there has been a flat trend over the 10-year period since 1998.  But some may object that starting the trend with the record year 1998 introduces an "artifact".

    So if we start the record with 2001 we show a slight cooling trend in three of the four records (Hadley, UAH, RSS) and a flat trend in GISS.

    And the WMO tells us 2008 is likely to continue to be cooler than average. So we have an 8-year flat to cooling trend.

    Whether this is the start of a longer-term flat or slight cooling trend is anyone's guess.

    As you point out, the record shows that the planet has been warming since records started (and long before any significant anthropogenic CO2) in 1850, and that this warming has occurred over three multidecadal warming cycles with intermittent multidecadal cooling cycles and an overall warming trend of 0.6 to 0.7C per century.

    I agree fully with you that it is logical to assume that this warming trend will continue (for whatever reasons) into the 21st century.

    Until we really understand what caused the earlier warming cycles of the late 19th century and the early 20th century, plus what caused the intermittent cooling periods and the current "plateau", we cannot really be sure that this all has anything to do with CO2.

    The point here is that you cannot look at 5-year trailing averages to see what is happening at the curve's "rightmost end".  You have to go to the actual data points.  And, yes, these data show that the warming has stopped (for now).

    IPCC Chairman, Dr. Pachauri, has said he would look into the reasons for the most recent "plateau", adding that he hoped this would not influence people into thinking that global warming is "hogwash".

    So let's see what his conclusions will be and what will happen over the next few years.

    It is probably safe to predict that, if the flat to cooling trend continues for a few more years while CO2 emissions continue, many people will start concluding that the suggested link between temperature and CO2 is tenuous (particularly since it was only really observed during the most recent warming cycle) and that AGW is not really the serious threat some would have us believe.

    We shall see.

  • Expanding MNG's agenda

    MNG's agenda is spot on, but it needs a bit of "fleshing out" to be more specific.

    I hope (nicely) that this will give Grist readers a clearer understanding of this (very nice) agenda:

    1.     Do no harm.  (i.e. do not engage in unsubstantiated fear mongering to the general public to sell a multi-billion dollar political agenda that will benefit a few at the expense of everyone, particularly the least affluent in the world, and otherwise accomplish nothing)
    2.     If you have time left over, try to make things better than they were when you arrived. (i.e. direct your resources to solving the real problems humanity faces today plus anticipating any unfavorable climate changes that may occur in the future and prepare for these potential changes before they occur). While attempting to do this, try not to violate hidden-agenda item 1, noted above.

    I hope I expressed this nicely, MNG.

  • Michael is wrong on IPCC

    Sorry, Michael, your last post was not very convincing.

    IPCC is trying to sell a message to the world (i.e. that increasing human CO2 emissions are causing temperatures to rise to dangerous levels).

    This is being done to justify draconian carbon taxes or cap and trade schemes (which UN would like to implement across all nations).

    This message still had some semblance of validity a few years ago, but recent developments show that it is now very doubtful.

    It will only be a matter of time until this whole bubble bursts and it becomes clear to one and all that (as you put it) the whole concern was based on nothing but hype to justify a political agenda.

    Will this happen in one year, in two years or in five years?

    My guess it is closer to one year than five years.

    What is your guess on this?

  • The AGW hypothesis of Mister Nice Guy

    How sound is the AGW hypothesis?

    AGW aficionados, even the "very nice" ones like "Mister Nice Guy" are beginning to have problems defending the AGW hypothesis, as the facts on the ground (i.e. the temperature record for the past 10 years) no longer support this hypothesis, and the whole AGW story is beginning to become unraveled.

    These individuals resort to rationalizations in support of their "belief" that become more and more bizarre.

    To put it bluntly:  atmospheric CO2 has continued to increase over the past 10 years at record rates, yet temperatures have actually decreased slightly.  Why is this?

    Prior to 1998 there was a 22-year period when both temperature and CO2 increased.  These years are the "golden period" of AGW, when warming and CO2 appeared to be really in sync.

    Before this, there was a 30+ year period when CO2 increased and temperature declined (1944-1976).  How can this be explained?

    And prior to this period there was a 30+ year period (from 1910 to 1944) that recorded around 60% of all the warming observed over the entire 20th century, when there was only a minor increase in CO2.  What caused this temperature increase, and, if it cannot be explained, how do we know that these same "unexplained" factors did not cause the 1976-1998 warming (rather than increased CO2)?

    The answers to these questions are obviously missing.  Even very nice persons like MNG avoid addressing these basic questions (because they cannot find answers).

    Yet, despite these observed facts to the contrary, AGW supporters (including the very nice ones like MNG) are (nicely) urging Grist readers to believe that anthropogenic CO2 emissions are the principal drivers of climate despite any real solid supporting evidence.

    Are these AGW supporters (even the very nice ones like MNG) trying to bamboozle us (nicely, of course)?

    Dear Grist readers, I suggest you make up your own minds on this and not rely on (very nice) individuals (like MNG) to do your thinking for you.  They may have a (not so very nice) hidden agenda.

  • Weather and climate

    Jabailo discussed this topic (April 23), but I believe his blog needs further clarification.

    Webster (online) tells us:

    Weather: state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness

    Climate: The average course or condition of the weather at a place usually over a period of years as exhibited by temperature, wind velocity and precipitation

    In other words, weather comes first, and is then integrated over a period of time to define climate "at a place".

    In today's world where "climate" has become a multibillion-dollar business the meanings have shifted a bit and the words have gotten a new spin.

    Climate is now the integration of the weather, not only over a period of years (as Webster tells us), but also globally over all places from Antarctica to Congo to Siberia, etc. (rather than just one place, as Webster defines it) and usually refers to periods of at least ten years (rather than just years), depending on what is going on.

    Weather is pretty much as Webster has defined it with one notable exception:  weather is now perceived to be the result of climate, i.e. more droughts, floods and storms are caused by global climate change.  

    This is a basic philosophical difference: Webster tells us that weather comes first to define climate; today's new spin tells us climate changes first, causing weather changes to follow.

    There is another factor that has been introduced by "climate scientists" who support the hypothesis of anthropogenic greenhouse warming (AGW), also known as "man-made global warming".

    This is the "universal inverse C:W relationship of climatology", which works as follows:

    If it is Warming ("W"), it is "Climate ("C")

    If it is Cooling ("C"), it is "Weather" ("W")

    Once you understand the basics, jabailo, it's really quite easy.

  • A nice tip for MNG and other Grist readers

    Hi MNG,

    You wrote (very nicely):
    "Those who feel the 21-point smoothed trend does not meet their needs are welcome to look at this 5-year-average trend line, or to ignore the portion of the 21-point smoothed trend line which extends beyond 1997."

    Rather than using manipulated, adjusted or "smoothed" data, I would suggest that those who want to know what is really going on should go to the original source of the data as published and look at what these data points indicate, doing their own analyses of trend lines, etc.

    A tip for Grist readers:  by going to the original data you have the advantage of being able to make up your own mind on what the data indicate, rather than letting someone else (even a very nice person like MNG) do this for you.

    I hope I communicated this tip nicely, and that you, MNG, will not be offended.

    "IPCC is not a big employer or a major funding agency."

    Not directly, anyway.

    But if there were no UN there would be no IPCC.

    If there were no IPCC there would be no highly publicized AGW scare.

    If there were no highly publicized AGW scare, there would be no need for billions of dollars of taxpayer-funded climate research (better spend all that money on a real problem).

    And if the research shows that there is no AGW problem and that everything is likely to be OK it does not get repeat government funding (no crisis = no funding).

    That's the connection.

  • Note to jbullfrog

    Hi jbullfrog,

    It's true that the Hadley record shows only a very slight cooling from 1998 to 2008, and it is anyone's guess whether this will continue and, if so, for how long.

    No really big deal, but it makes the IPCC projection of 0.2C warming per decade (for the next 2 decades) look rather dubious, but, what the hell, you can't guess them right every time, even with fancy computer models.

    But at least Hadley learned a lesson.

    Rather than predicting that "next year will be a record scorcher" as they did twice in a row (and then have to crawl back with a rationalization why it did not turn out that way), they did not fall into that trap for the year 2008 (I guess the handwriting was already on the wall).

    But one does learn from past mistakes.

  • CO2 and temp link for MNG

    Hi MNG,

    Liked your automobile analogy.

    Also liked your statement: "Just because recent changes in temperature anomaly don't seem to correlate linearly and in sync with changes in CO2 at Mauna Loa, that doesn't mean rising atmospheric CO2 concentrations have no effect on temperatures."

    I could rephrase this is follows:
    "Just because recent changes in temperature anomaly don't seem to correlate linearly and in sync with changes in CO2 at Mauna Loa, that doesn't mean rising atmospheric CO2 concentrations do have any effect whatsoever on temperatures."

    Both sentences make sense.

    The second one may even make just a little more sense than the first one, although that is just my opinion.

    I could add:
    "Just because none of the cycles of warming and cooling observed over the past 150+ years, with the notable exception of the 22-year period from 1976 to 1998, show any correlation between atmospheric CO2 concentrations and temperatures, that doesn't mean rising atmospheric CO2 concentrations have no effect on temperatures."

    Nor does this observed fact show that rising CO2 concentrations do have any effect on temperatures.

    But it sure raises an inconvenient question, leading to the statement:

    And, until IPCC or anyone else can show what caused the warming cycles prior to the increase in CO2 concentrations and why these same factors were not responsible for the most recent warming cycle it makes the case for CO2/temperature causality very weak.  

    In fact, without such a detailed analysis eliminating any other unexplained factors, this causality is based on greenhouse theory, computer models and conjecture alone.

    But I welcome your links to scientific studies that have determined the reasons for the "pre-CO2" warming cycles and have specifically concluded that these reasons could not also have caused the most recent warming.  

    I am sure that other Grist readers beside myself are eagerly awaiting your response in order to clear up this most important issue that lies at the heart of the entire AGW hypothesis.  

    If possible, I would nicely suggest that you stick to the specific issue here and avoid side issues and analogies, even though these may all be very interesting.

    Hope I said this nicely enough.

  • Cycles in the temperature record

    Mister Nice Guy has very nicely helped enlighten Grist readers with some very polite words of wisdom:

    "Hopefully by looking at these three graphs, showing monthly linear trend, yearly linear trend, 5-year moving-point-average trend, and 21 point smoothed trend, Grist readers can see the effect of the various time spans used in the trend calculations and weigh the significance of the various downswings and upswings in the temperature anomaly over the past 150 years."

    Jabailo has also shed some very helpful light on long term versus short term trends in the record.

    As MNG has informed Grist readers there have been distinct "downswings and upswings in the temperature anomaly over the past 150 years".

    The record shows that this is, indeed, true, as MNG suggests.  If we use the Hadley record that goes back to 1850 we can identify these multidecadal "downswings and upswings" more closely.  We see that there were three cycles of warming and four cycles of lesser cooling, with an underlying overall trend of warming over the entire period.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    If we correlate the linear rate of change of the temperature anomaly and the linear temperature change with the change in atmospheric CO2 over these cycles, we see the following:

    1850-1860:  linear cooling trend of -0.112C/decade, linear change -0.11C, negl. change in CO2

    1860-1879: linear warming trend of +0.176C/decade, linear change +0.35C, 2 ppm CO2 increase

    1879-1906: linear cooling trend of -0.039C/decade, linear change -0.11C, 5 ppm CO2 increase

    1906-1940: linear warming trend of +0.130C/decade, linear change +0.44C, 14 ppm CO2 increase

    1940-1976: linear cooling trend of -0.006C/decade, linear change -0.02C, 25 ppm CO2 increase

    1976-1998: linear warming trend of +0.159C/decade, linear change +0.35C, 33 ppm CO2 increase

    1998-2008: linear cooling trend of -0.021C/decade, linear change -0.02C, 20 ppm CO2 increase

    Most rapid rate of increase was in the 20-year cycle 1860-1879, followed by the 22-year cycle 1976-1998 and the 36-year cycle 1906-1940.

    Roughly 30% of the total warming occurred in the most recent warming cycle (1976-1998), another 30% in the late 19th-century warming cycle (1860-1879) and roughly 40% in the early 20th-century warming cycle (1906-1940).  Intermittent cooling cycles reversed roughly 10% of the warming over the entire 150+ year record, for a net overall linear warming of somewhat over 1C.

    The data do not show an apparent correlation between warming and CO2 over the individual cycles.  

    Hope this, together with the input from MNG helps Grist readers see the cyclical nature of the "downswings and upswings" mentioned by MNG and the correlation between temperature and CO2 over these cycles.

  • jbullfrog got it wrong again

    Actually, jbullfrog, you got it wrong. I am not a "conspiracy theorist".

    Read what I wrote, don't try to re-phrase it with your spin on it.

    IPCC was set up by the UN, a political body, to investigate anthropogenic influences on climate (i.e. primarily the impact of human CO2 on warming) and to report whether these changes would have any negative impacts on humanity and the environment, with the underlying agenda to find ways to mitigate any identified potential problems by implementing political solutions.

    The existence of the IPCC depends on (a) the identification of anthropogenic climate forcing factors and (b) the projection that the impact of these is likely to be more negative than positive, unless (c) mitigating steps are taken.  

    No anthropogenic forcing with potential for negative impact = no need for IPCC to exist.   Bureaucratic committees do not easily disband voluntarily, so it is a matter of self-preservation to keep a level of alarm alive that AGW could cause serious problems.

     "Climate scientists" must get taxpayer-funded grants to do their work.  If the work meets the political agenda of the IPCC, it will get funding.  If not, it has a lower chance. The motto here is: "no crisis = no funding".  Billions of dollars are at stake here and the smart researchers know what is necessary to get the funding they need.  The most effective reports conclude with statements such as "the problem could become more serious, but additional work is required to identify the magnitude of this potential problem" (guaranteed to get more funding from politicians who also benefit from a potential crisis).

    Some of these "climate scientists" have gotten stuck in the AGW paradigm that pays their salaries.  To challenge the paradigm is to risk losing their funding and getting scorn from colleagues who are also stuck in the paradigm or fear for their funding.

    In such an "in-bred" society the "peer review" process is often just a rubber-stamping by like-minded colleagues as was demonstrated by the Mann hockey stick scandal.

    "Serious scientific journals" also fall into the trap.  Papers that defend or support the AGW paradigm are more eagerly accepted for publication than those, which challenge this paradigm.

    This is not to say that many of these "climate scientists" do not truly believe there could be a problem, and some may actually have the warm feeling that they are doing something good to "save the planet".

    Some of these "climate scientists" become "activists" or "alarmists".  A classical example is James E. Hansen, paid by the US government to give un-biased weather and climate information to the US public, but instead of doing his job he is spreading scare stories of imminent "tipping points" with horrible consequences for humanity, other species and the planet itself unless carbon taxes are implemented immediately.  In other cases it is the politicians, such as Al Gore or Ban Ki Moon, that do the scare mongering in order to get public support for their personal, financial or political agendas.

    We even have Hollywood and the Nobel committee handing out politically motivated prizes.

    This is not a "conspiracy".  It is "agenda driven science" and plain old human nature.  Remember that politicians, bureaucrats and scientists are all just human beings.

    You accuse the oil and coal lobbies of doing the same.  The managers and directors of these companies are also just human beings.  I cannot disagree in principle that both sides use the same approach.  I have just seen a much lower volume of "agenda driven science" from these lobbies than from the AGW lobbies that are spending billions of dollars annually to sell their message.  

    AGW has truly become "big business", and the vast majority of papers out there on climate change support the AGW viewpoint.  Several billions of dollars go a long way toward building "consensus".

    And then you have the media (also directed by human beings).  Nothing sells as well (and brings in profits as surely) as a good "imminent disaster" story.  Here again there may be some individuals who think they are doing something good for humanity by alarming the public to a problem that is sure to come.  Others are in it for the "bucks".

    No conspiracy required, jbullfrog.  Just plain old folks, billions of dollars and "agenda driven science" at work.

  • jabailo is right

    Of course jabailo is right.

    If this whole AGW debate were just a scientific discussion among atmospheric scientists, astronomers and physicists, there would not be too much public interest and these blog sites would not exist.

    What has made it everyone's business is that it is a political discussion involving policy measures that would cost hundreds of billions of dollars and achieve absolutely nothing.

    IPCC was set up by politicians and bureaucrats to help justify these policy measures.

    The IPCC charter is not to find the "truth" about what drives changes in climate, it is to find the "proof" for anthropogenic causes of climate change and project that these will have adverse effects unless "measures are taken" to reduce GHG emissions (primarily CO2).

    The "measures" involve carbon taxes or cap and trade schemes with very large sums of money being shuffled around by bureaucrats and politicians, hedge funds, carbon trading companies, etc., with "big bucks" to be made.  Al Gore and others are already lined up at the trough, hoping to make a killing on carbon trading.  Other public figures are relishing the thought of the prestige and power (and maybe a bit of financial gain on the side) they will get from having billions of dollars to shuffle around.

    Many of the so-called "climate experts" have sold out to the IPCC, responding to the axiom in publicly funded research of "no crisis = no funding".  This has made the so-called "peer review" process a sham (sort of like a court proceeding in the old Soviet Union).

    Then there are the activists who pose as "climate experts" (Hansen Schneider, etc.) to spread the message of impending disaster unless we "act now".  "Act now" = take "measures" (see above).

    The media love a good hysteria wave because it generates good public interest and profits.

    Who will pay for this whole circus?

    Everyone.  

    The worst hit will be those already at the bottom of the pyramid, who will continue to be denied access to clean drinking water and electrical power, in order to "save the planet" from the added CO2 this would generate.

    What positive results will the implementation of these measures have?

    None.

    That's why jabailo is right when he says everyone needs to get involved in this discussion and not rely on only the opinions of the so-called "climate experts", who have sold out to the IPCC or the climate alarmists, who hope to gain from this wave of hysteria.

  • Reply to jbullfrog

    Hi jbullfrog,

    You wrote: "This temperature record you keep talking about, Max, is not "observed facts."

    IPCC believes in it jbullfrog.  Don't you?  It may have some built in human errors and UHI distortions, etc., especially in later years as AC units were put in next to thermometers and asphalt parking lots were put in.  But these records are all we have as far as observed surface air temperature records are concerned.  So they are as close to "facts" as we are going to get.

    IPCC uses this record to sell its AGW story.  Problem is, they cherry pick the part of the record they want to talk about and ignore the part that does not support their AGW story.

    You wrote: "Who are you to say this one temperature record is correct, or more brashly, to say that it proves anything, when there are so many other temperature records that suggest the opposite? Clearly there is some explanation, but who are you to decide what it is?"

    Which other records "suggest the opposite"?  Please specify what you are talking about.
    The two satellite records (UAH, RSS) agree with flat to slight cooling since 1998. GISS is the "odd man out" and shows flat to slight warming. Over the past seven years (2001-2008) all records agree with flat to slight cooling.

    The two satellite records can obviously not be used to track the early 20th-century and late 19th-century warming cycles, because they did not exist.

    I personally have more faith in Hadley than GISS, in view of the recent disclosures of errors in the GISS record for the USA, which had to be corrected quietly.  I also have a bit of a problem with the objectivity of James E. Hansen, since he has become an AGW activist preaching "tipping point" stories instead of giving the US taxpayers unbiased information on weather and climate.  And, as noted above, I have seen that when comparing trends (particularly over the past 10 years), the GISS record is "odd man out" compared to the other three (Hadley, UAH and RSS).

    Hope this clears things up for you.

  • atreyger's aversion to facts

    Hi atreyger,

    You apparently do not like discussing observed facts (such as the Hadley temperature record), when these facts do not support your preconceived notions.

    As I showed you, this record shows that there have been several multidecadal warming/cooling cycles over the past 150+ years that have nothing to do with AGW.

    It further shows that the late 20th century warming is not unusual when compared to other warming periods prior to increased CO2 concentrations.

    It confirms that warming before this latest period was at least twice as great as during this period.

    And finally it shows that warming has essentially stopped since 1998 despite continued increase in CO2 concentrations.

    That is the observed truth, even if it is a bit "inconvenient" for you to accept, atreyger.

    But cheer up.  We will not fry or drown because of AGW.  (I'm actually more concerned that AGW has reversed and we may freeze, instead, which I view as a much more serious problem for humanity).

  • What "other scientists" think

    Hi jbullfrog,

    You wrote:
    "Furthermore, it definitely does matter whether other scientists find the work to be robust and legitimate."

    Not really.

    "Other scientists" at the time thought Alfred Wegener's theory of "continental drift" was not "robust and legitimate".  

    They were even in "overall consensus" of this view, as is being claimed now for the AGW hypothesis.

    And that was before there was a multi-billion dollar AGW industry paying scientists to find the AGW paradigm "robust and legitimate".

    Wake up to the facts, jbullfrog.  It's a multibillion dollar scam.

  • Facts for atreyger

    Go back to the source, atreyger.  You will see that no data have been "fudged".

    The record shows that there have been three major warming periods since 1860, two cooling periods and one most recent flat period.  Those are the unvarnished facts.

    The record also shows that there is no apparent correlation of the temperature change with the change in atmospheric CO2 concentration over these periods.

    Just facts, that's all.

    Everything else is model gibberish and hype.

  • Message for jbullfrog

    Hi jbullfrog,

    You got it wrong when you wrote:
    "The question at hand is not whether we like these scientists' ideas or the consequences they imply. It is whether their work is legitimate and robust based on the opinions of other scientists, not Joe Schmo bloggers."

    Here's what's wrong with that.

    The work does not have to be "robust based on the opinions of other scientists (or bloggers)", it has to be "robust based on sound observed physical evidence".

    The AGW link between anthropogenic GHGs (primarily CO2) and temperature is not.

    This hypothesis cannot explain earlier periods of global warming (late 19th, early 20th centuries), the mid-20th-century cooling period and the current "plateau" in warming.  In fact, over the entire 150+ years of the temperature record, it only shows good correlation for the 22-year period 1976-1998.  22 out of 150 is about a 15% hit rate; not too "robust".

    Forget "opinions of other scientists", bring evidence.

  • Some CO2 facts for Pangolin

    Here's one for you, Pangolin, since you seem to be getting lonely.
    Correlation between CO2 and temperature

    Here is a way to get a good visual look at the correlation between atmospheric CO2 concentration and temperature.

    Take the data below (from the Hadley global temperature record and the atmospheric CO2 record according to Mauna Loa and IPCC) and plot them into Excel with a 2-axis chart.

    The correlation will become obvious.

    Period......Dtemp......DCO2
    1860-1879...+0.39......2
    1879-1906...-0.13......5
    1906-1940...+0.56......14

    1976-1998...+0.39......33
    1998-2008......0.00......20

    Dtemp is linear temperature change over period in degrees C
    DCO2 is increase in atmospheric CO2 concentration over period in ppmv

    Why do we not see this simple chart in any IPCC report?

  • Coby Beck was wrong

    Coby Beck made this statement (some time back): "I am not aware of a temperature record that shows warming starting in 1850, it does not get going until around 1900."

    This statement is incorrect.  Coby should check the Hadley record, which goes back well before 1900.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...  

    The Hadley record shows a period of slight cooling from 1850, when its record began, to around 1860.

    From 1860 through 1879 there was a period of rapid warming.  If Coby were to download the Hadley data into Excel and plot a trend line, he would see that the warming trend over this period was 0.196 degC per decade (while CO2 rose by 2 ppmv), higher than any subsequent period, INCLUDING the much-ballyhooed period starting in 1976 and ending in 1998, which had a warming trend of 0.175 degC per decade (while CO2 rose by 33 ppmv).

    The 20-year 1860-1879 period accounted for around 30% of all the warming since the record started.

    IPCC (like Coby) ignore this early period of warming.

    It is an "inconvenient" period, since it cannot be explained by AGW.  It cannot be explained by unusual solar activity.  In fact, it cannot be explained.

    The second period of warming started in 1906 and ran to around 1940.  This period is very briefly mentioned in passing in AR4 WG1 Chapter 9 (p.691): "Detection and attribution as well as modeling studies indicate more uncertainty regarding the causes of early 20th-century warming than the recent warming."

    40% of the total temperature rise occurred during this 34-year period, although the linear trend was somewhat lower than in the other two periods at 0.161 degC per decade.  CO2 rose by 14 ppmv over this period.

    IPCC states (Chapter 3, p.240): "The picture prior to 1976 has essentially not changed and is therefore not repeated in detail here."

    Now IPCC also states (p.681) "The simulations also show that it is not possible to reproduce the large 20th-century warming without anthropogenic forcing regardless of which solar or volcanic forcing reconstruction is used, stressing the impact of human activity on the recent warming" and (p.685) that the warming during the most recent period "can only be reproduced when models are forced with combinations of external forcings that include anthropogenic forcings".

    The logic"
    1.    We cannot explain what caused the warming of two earlier periods (1860-1879 and 1906-1940)
    2.    We are not interested in clearing up the "uncertainties" of any unexplained forcing factors for these periods, in fact we are not going to talk about them at all.
    3.    We know that AGW largely contributed to the warming from 1976 to 1998.
    4.    We know this is the case, because our models cannot explain it otherwise (i.e. AGW is guilty by "default").

    Until IPCC investigates in detail both earlier periods, which together account for 70% of the total warming since records began, they cannot name CO2 (and other GHG) as the culprit by default for the most recent warming period, which accounts for the remaining 30% of the total warming.

    This is the fatal flaw in the AGW hypothesis.

  • Andrew will not answer

    Hi Black Wallaby,

    Thanks for tip.

    Unfortunately, Andrew Dessler's track record has shown me that when the discussion gets "dicey" and too close to actual facts he prefers to avoid participation.

    He is, undoubtedly, an acknowledged "expert" in his field of climatology, and it would be beneficial for all who are tuned into this thread to have him share his expertise with others that do not have this knowledge in an open debate.  

    But, since he is also an engaged advocate rather than just an impartial scientist, it has become clear that he is reluctant to engage in debate on the facts, since he may be aware that these will not support his position.

    I have had good discussions with Andrew on other climate-related issues in the past, but I seriously doubt that he will take up the challenge to answer this time, because the risk of losing the debate is just too great.  The facts are stacked against him.

    As we say here in Switzerland, "c'est la vie" (or "so isch es ebbe", depending on where you live).

  • One for Andrew Dessler

    Here's one for Andrew Dessler.

    Several years ago Danish scientists, Henrik Svensmark and Eigil Friis-Christensen proposed a theory linking global climate with the activity of the sun, via cosmic rays.

    Svensmark's subsequent lab results demonstrated an observed link between cosmic rays and cloud formation.  Whether the CLOUD study now underway at CERN will confirm this on a larger scale is a matter of conjecture at this point.

    Critics of Svensmark's theory point out that, while it may have shown fairly good correlation with global temperature in earlier years the link after around the mid-1980s is poor.

    This is often referred to as the "fatal flaw" in Svensmark's theory.

    This argument may be valid, but it raises the question:
    Is there an actually observed link between atmospheric CO2 concentration and global temperature?

    The Hadley Centre has a published record of "monthly globally averaged land and sea surface temperature" that goes back to 1850.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ... ...

    Actual measurements of atmospheric CO2 concentration only started in 1958.
    http://www.esrl.noaa.gov/gmd/ccgg/trends/co2_data_mlo.htm ... ...

    IPCC estimates based on ice core readings go back to pre-industrial times. These show an estimated gradual increase from around 285 ppm in 1850 to 315 ppm in 1958, when actual measurements started.  See the IPCC 2007 SPM report:
    http://ipcc-wg1.ucar.edu/wg1/Report/AR4WG1_Print_SPM.pdf

    CO2 concentrations have risen steadily over the entire period.  The rate of increase has accelerated slightly over the period, particularly following WWII.

    Global temperatures have risen over the period, but a closer look at the record shows that this has been anything but steady.

    Period.........Trend..Years..Change    

    1860-1879    +0.196    20    +0.39    
    1879-1906    -0.047    27    -0.13    
    1906-1940    +0.161    35    +0.56    
    1940-1976    -0.020    36     -0.07

    Trend is linear decadal trend in degreesC/decade
    Change is linear change over period in degreesC

    Over the past 150 years since the record started temperature has increased by around 1.1C.

    Between 1850 and around 1860 there was a slight cooling trend.  

    This trend reversed to a warming trend for the next 20 years until around 1879 (at +0.196C per decade this period shows the highest decadal rate of increase since records have been taken) and represents around 30% of the total warming recorded since 1850. There was essentially no increase in CO2 during these "horse and buggy" years.  

    This was followed by another cooling trend until around 1906 (-0.047C per decade).  

    Then came another warming trend until around 1940 (+0.161C per decade), representing around 40% of the total warming recorded since 1850.

    This period was followed by a slight cooling trend until around 1976  (-0.02C per decade), during the post-war boom period of rapid increase in CO2

    Following this, we had a trend with the second highest decadal rate of increase (+0.175C per decade) from 1976 to around 1998.  This trend occurred during a period of rapid CO2 increase and represented 30% of the total warming from 1850 to today.  This period has gotten a lot of attention as evidence of anthropogenic greenhouse warming (AGW).

    Since the end of the 20th century, this rapid warming trend has stopped.  Over the ten-year period since 1998 there has actually been a very slight cooling trend, despite the continued high rate of increase of CO2.  Starting the trend with the year 2001 rather than the strong El Niño year 1998 shows the same flat to slight cooling trend.

    In summary, there were three warming periods that contributed to the overall warming plus two periods of cooling and the most recent "plateau" showing essentially no change.

    And it appears that last 25 years of the 20th century provide the only observed link between CO2 and temperature.

    The immediately preceding period had CO2 increase with cooling.

    The immediately ensuing period since the end of the 20th century shows slight cooling with high increase in CO2.

    The late 19th century warming period showed the highest rate of temperature increase of all periods recorded, with essentially no CO2 increase whatsoever.

    The early 20th century warming period also showed warming, with relatively small increase in CO2.

    In summary, the actually observed data show that there does not appear to be a very "robust" link between atmospheric CO2 concentration and global temperature.

    IPCC has used the late 20th century warming cycle to demonstrate the anthropogenic cause stating in its AR4 WG1 report Chapter 9 (p.681):
    http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/ar4-wg1- ...

    "The simulations also show that it is not possible to reproduce large 20th-century warming without anthropogenic forcing regardless of which solar or volcanic forcing reconstruction is used,... stressing the impact of human activity on the recent warming."

    In other words, since no other cause can be identified to explain the observed warming other than anthropogenic forcing (from greenhouse gases), this must be the cause by default.

    This assumption is based on the rather weak foundation of greenhouse theory, 25 years of observation, model studies, and conjecture.  

    Most damaging for this assumption is the fact that no analysis has been made of the two prior warming periods in order to support this suggestion, despite the fact that these periods together count for 70% of the warming observed over the entire record.

    Strangely IPCC does not even mention the late 19th century period that showed the highest decadal rate of temperature rise of all periods since measurements started.  Nor has an analysis been made to determine the causes for this period of rapid warming.  It is obvious that it could not have been caused by increased CO2, as there was no significant increase.  Sunspot records show no unusual solar activity that could have been a factor. What, then, were these "unexplained" causes?  Why have they not been investigated?

    As regards the warming period of the early 20th century, IPCC states (p.691):
    "Detection and attribution as well as modelling studies indicate more uncertainty regarding the causes of early 20th-century warming than the recent warming."

    Again there are apparently "unexplained" causes resulting in "uncertainty", but, again, no studies have been made to clear up this uncertainty and attempt to understand how large an impact these "unexplained" causes might have had.

    Could these same "unexplained" causes have been the principle forcing factor for the late 20th century warming, rather than the assumed "anthropogenic forcing" from greenhouse gases?  How can we be sure this is not the case?

    Only by making these analyses and clearly identifying that there were no major "unexplained" factors in the two earlier warming periods can one make the claim that AGW is the predominant forcing factor for late 20th century warming

    To simply assert that this is so "by default" since no other explanation can be found is no argument at all.

  • Some FAQ for amazingdrx

    Hi amazingdrx,

    Here are some FAQ concerning the current "global warming" scare:

    Q: What do politicians like?
    A: Shuffling around large sums of public money to enhance their personal power and prestige.

    Q: What do "scientists" (outside the private sector) like?
    A: Getting large sums of public money in grants to support their work and pay their salaries.

    Q: What do politicians need to justify research grants to "scientists"?
    A: The specter of a potential disaster if this research work is not done to identify and solve the potential "problem" for society.

    Q: What do the media like?
    A: Potential disaster stories (i.e. climate hysteria) to sell copy or TV ratings (and earn higher profits).

    Q: What do politicians want to achieve with the current climate hysteria?
    A: Support by the general public for taxes, etc, that will generate large sums of public money at the taxpayers' expense for them to shuffle around.

    Q: Who will pay for this circus?
    A: Everyone, especially those at the bottom of the pyramid today. This includes the hundreds of billions in the very poorest regions who will be denied access to electrical power because of overriding "greenhouse gas" global climate considerations.

    Q: Who will benefit?
    A: Beside the "climatologists" this includes the media, politicians, "low carbon footprint" industries, hedge funds and those individuals plus their corporations that are involved in (and will be earning profits from) carbon trading schemes (such as the Nobel Prize winner, Al Gore).

    Q: Why should we fight against this?
    A: Because this is a money-making scam for the already wealthy few at the expense of many, which we will all otherwise be forced to finance, and most importantly, because it will have absolutely no impact whatsoever on the future climate on this planet.

    Hoping this has cleared up some questions related to the current AGW hysteria...

    Whaddaya think?

    Checked out your info on UV exposure / melanoma / Vitamin D / etc. and agree.  The correlations are not straightforward.  I had always been led to believe that the link was fairly strong (at least for the non-melanoma skin cancer), but it looks like there are mixed data even there.  And heredity is one of the big factors.

    This is where Andrew Dessler may have (accidentally) gotten it right this time in comparing this with man-made global warming, where the correlations (this time between man-made CO2 and global warming) are also not straightforward.

    But Andrew likes to make these analogies which sometimes end up backfiring on him, in order to "sell" his personal take on potentially disastrous anthropogenic greenhouse warming (AGW) to an audience of non-experts, without having to defend the AGW theory itself or the sometimes spotty data used to support it.

    When he gets into defending a specific AGW claim (such as on an earlier thread concerning the link between hurricanes and AGW) he sometimes gets into trouble.

    On a previous thread he used an analogy to "obesity" (and got irate responses from contributors who felt personally attacked).

    His other ploy has been to "trash" an individual or group of individuals who have spoken out against the IPCC or some of the more ridiculous predictions of disaster from AGW.  These individuals are not "qualified" to have a relevant opinion on such matters. There was a series of these threads around the end of last year.  These threads serve to sell the concept of "scientific consensus" on AGW by attempting to discount those individuals who do not share the so-called consensus view.

    Direct discussion with Andrew is interesting, however.  In a direct interchange he brings his ideas across very well and one can learn from them.  And he is certainly more than knowledgeable when it comes to "climate science" concepts.

    But, unfortunately, he often makes his initial comments to get a discussion started and reacts to the first few responses and, after that, prefers to remain aloof and let others do the debating.

    But I'm glad you are on the site and contributing.  We need as many rational and involved contributors as possible. And you'll have fun.

  • Aussie humor

    Hey amazingdrx,

    As a neutral observer and contibutor here, I kinda like the occasional Aussie humor from BW to cut through some of the blog-fog hysteria of the clim-alarmists that post here.

    And then again, sometimes he brings (shudder!) FACTS.  I know that these may be discomforting to some when they show that the AGW scare is misguided, but, hey fella, that's what this AGW debate (and this and other sites) are all about.

    Right?

    Hi GF,

    You have not taken a stand on the relative "fatal flaws" of Svensmark's cosmoclimatology hypothesis and the AGW hypothesis.

    Much has been written about the former, while far less is reported about the latter.

    Can you point out the observed differences between the two, if any?

  • Climate vs. weather in early 2008

    World-wide weather versus climate in early 2008

    Milwaukee resident, as he shovels the snow from his driveway:  It's Easter and we have to hide the kids' Easter eggs in the snow.  What the hell happened to "global warming"?

    Wife (an ardent AGW supporter):  Silly, this snow is just "weather", not "climate".

    Chinese garment worker in Guangdong Province, China, waiting in the first snow in many decades to catch a delayed train back to her native province in the north during Chinese New Year vacation, translated from Mandarin:  What is going on here?  The Central Committee tells us there is "global warming", not snow, here in Gaungdong Province.

    Other stranded passenger, who believes in "global warming": Important difference, please:  this snow is just "weather", not "climate".

    Iraqi shop-owner, clearing the first snow he has ever seen from the steps leading to his shop (during moderate sniper fire), translated from Arabic:  By Allah, I have never seen this white stuff here; don't we have "global warming"?  What is going on here?

    Wife (an AGW believer):  Hassam, dear, this snow is only anomaly of unusually "cold weather"; global warming, on the other hand, is absolutely certain  (inshallah) "climate change".  Believe me.

    Farmer, to his son as he is trying in vain to start his pickup truck in Minnesota:  By golly, it's 40 below zero this morning - never ever been so cold here; where's the "global warming" they promised us?,

    Son (a college student, who has read and supports IPCC):  Relax, Dad this is only cold "weather", but we are actually experiencing warmer "climate".

    Greek goat herder to his wife as temperatures fall to an all-time low of minus 18C and snow blankets the grazing field for his shivering goats:  Never seen such cold before.  Are we not having "global warming"?

    Wife (who reads and believes IPCC reports): Kostas, you must understand the difference.  What we now see is cold "weather". What we are certain to feel in the future is warm "climate".

    Tampa area orange grower:  It's below +20 degrees (F) here this morning and tomorrow is supposed to get even colder.  My oranges are dying.  Where is "global warming" when we really need it?

    Son, who is a University of Tampa environmental science major:  But Dad you must realize that this current cold snap is just a temporary change in the "weather", while the unequivocal "climate" trend, as confirmed by IPCC climate models, is one of warming.

    Etc.

  • JCross does not believe IPCC either

    Hi John,

    I figured you would turn down the bet that 2020 would be warmer than 1998.

    Shows me how much confidence you really have in AGW and the IPCC.

    Looks like we agree on something here, John, and it is not AGW or the IPCC forecasts.

    It is quite simply that the warming over the 14-year period from 2006 (when IPCC put out their February 2007 report) to 2020 will be less than 0.106C.

    In other words, you are not even confident that the warming rate will be 0.076C/decade, when IPCC says it will be 0.2C/decade (or 2.6 times this rate).

    So much for your confidence in IPCC. Kinda agrees with mine.

    You have waffled around, John, but have backed down on this bet because you are not sure that AGW is really happening as IPCC claims. I can fully understand that.

    Maybe one of your supporters out there wants to take up the bet. By all means, it is open to anyone who is a strong enough believer in the IPCC version of AGW to be interested.

    How about it, josullivan58, Robco1, Pangolin, MisterNiceGuy?  Or even the venerable Dr. Andrew Dessler.  Any takers?

    Probably not.

    It was nice blogging with you anyway, John, as it gave me some insight into how strongly you really do have confidence in all this AGW stuff.

  • Tamino tale for JCross

    Hi John,

    A side issue.  You cited a Tamino tale.  Good for a chuckle.

    But let's examine the Tamino allegory (Wikipedia; comment by me).

    Prince Tamino has got lost in the forest [i.e. T. is having difficulty statistically seeing the forest for the trees] and now finds himself in a country which is ruled by the Queen of the Nights [also known as "never-never land"]. A huge monster [anthropogenic greenhouse warming] chases him and he is very frightened [in fact, he is hyterically terrified of certain doom]. He falls down in a faint [happens to the best of guys, when you are hysterically terrified of certain doom]. Three ladies who work for the Queen of the Nights come and kill the monster [the ladies are called "Sun", "Cloud" and "Reason"]. Then they see the handsome prince and they argue about which one of them will stay to look after him [Who will win? "Sun": the brightest, "Cloud": the coolest or "Reason": the most logical?   Actually, they all agree to share Tamino in a never-ending circle of happiness and love.  And they all live happily ever after...].

    I like stories with happy endings, don't you?

  • Bet for JCross

    Hi John,

    It sort of looks like you really do not want to make a bet on global warming.

    You apparently believe that it is going to get warmer due to AGW.  So does IPCC.  In fact, they project that it will warm on average at 0.2C per decade (over the next two decades).  

    They published this in early 2007, when 2006 global temperature data were in.  The Hadley record showed that the average annual temperature anomaly in 2006 was 0.421C.  So from 2006 to 2020 is 14 years.  At the projected average decadal rate of warming this means that 2020 should be at 0.421 + 0.28 = 0.701C, according to IPCC.

    But rather than holding your feet to the fire to go with the IPCC projection (which we apparently both feel is ridiculously high), I'm giving you a break by picking the much lower actual number for 1998 (the year warming stopped according to the Hadley record).  This number is only 0.526C, which is 0.175C lower than the IPCC projection for 2020.  If you really believe IPCC, you should jump at such a deal.

    IPCC projects that it should be 0.701C by 2020.

    You apparently believe IPCC. Or do you?

    I do not believe and bet you that IPCC is wrong in their projection.

    And I even "spot you" 0.175C, which just happens to be the actually observed amount of increase per decade over the last 25 years of the 20th century (the period which IPCC uses to "prove" accelerated global warming due to AGW). So I'm "spotting you" 10 years of warming.

    Now here's my problem with GISS.  I just do not have any faith in GISS numbers.
    ·    There have been disclosures of "funny numbers" coming out of GISS.  
    ·    James E. Hansen is no longer scientifically objective and neutral, since he has started acting like an AGW activist selling "tipping point" hysteria, rather than as a government employee who provides the U.S. public unbiased and accurate weather/climate data.  
    ·    The GISS record has been the "odd man out" compared to the other three records on warmest year, rate of warming/cooling, etc. (always erring on the high side).  

    And finally, if I had made a bet with you in 1984 that the temperature in 14 years (1998) in the USA would not be higher than it was in 1934 (the warmest year until then), I would have lost, only to find out long after you had cashed in the bet that the record had been "fudged" and that 1934 really was warmer than 1998.  

    Get the point?

    But rather than insisting that we use the UAH record, which I trust fully, I am willing to use the Hadley record.  It may not be transparent, and may have some built-in UHI distortion, but at least there are no indications that it has been compromised.

    So that's the deal.  If Hadley says 2020 has a higher annual globally averaged land and sea temperature anomaly than 0.526C, you win.  If not, you lose.  If the record is exactly 0.526C, we use the average between 2019 and 2020.

    If you really believe in AGW and in the IPCC, you should take the deal.

    If not, lets forget it.

    Can we move on?

    Thank you for your recent blog, Black Wallaby.  

    That was helpful input, especially your input on the Antarctic, and the very pertinent explanation of the wiggly black line as an arbitrarily selected 20-year smoothing of apparently unpublished code, which was selected to give a desired low frequency smoothing.  

    Solarmeter, thanks very much for taking the time to improve my understanding of the long time changes that are due far more to solar cycles than to man-made influences and the futility of tax increases to help stop global warming.   That helps a lot.

    Hi MNG,

    It's really great that you are "hoping to be nice", in agreeing with those that happen to share your own opinion, like josullivan58 or jcross.

    While this conduct is certainly admirable (provided one agrees with your position on things), it has nothing to do with critically challenging the AGW hype that is out there to really establish what the facts are.

    Being "nice" does not equate with being right.

    But I have to admit that you are really nice (provided others agree with your own opinion).

  • Some food for thought on global warming

     
    Hey folks,

    We have published records of "globally averaged land and sea surface temperature anomalies" (Hadley, GISS).

    We have records of the same "anomalies" based on the tropospheric record, as measured by satellites (UAH, RSS).  For many people these records are more pertinent than the surface record, for three reasons:

    ·    Greenhouse theory says that warming should start in the troposohere rather than at the surface.
    ·    Tropospheric measurements do not have the urban heat island distortion of the surface record.
    ·    Satellite measurements (which measure the entire land and sea) give a much more comprehensive measurement than the surface measurements, which are relatively spotty, especially over the oceans.

    All of these records show that there has been no warming over the past seven (or even ten) years.

    Three of the four records show that there has actually been a cooling (Hadley, RSS, UAH), while the fourth record (GISS) shows no warming.

    These are the (using an IPCC expression) "irrefutable" (if uncomfortable or inconvenient) facts.

    Now there are many rationalizations as to why these facts have been observed.  There have been claims that these seven years mean nothing.

    But there have been no valid refutations to date of the observed facts.

  • Nope, JCross

    Nope, JCross.

    Hadley annual is Hadley annual.  It gets reported for all to see. That's the basis without any fudging.

    1998 is 1998.  For most normal folks this starts on January 1 and ends on December 31.

    This year (1998) was the end of global warming, according to 3 of the 4 records.

    That's the basis for your claim of more warming and my claim of no more warming, not an "initial value on an average of several years (say 3 or 5)".

    Do not waffle on your bet as you did on the other discussion, JCross.

  • josullivan58 is wrong, yet once again!

    Hey josullivan58,

    What you claim is not really true. (In fact, it is totally untrue.)

    The source of the data is the globally averaged surface land and sea temperature anomaly records published for all to see by Hadley, UAH, RSS and GISS.

    These records all show a flat (or cooling) temperature trend over the past 7 years (since January 2001).

    Can you bring any evidence to refute this?  

    If so, please do do.

    If not, back off on your somewhat stupid comment that "commenters are knocking themselves out to convince everyone that there has been a plateau in global warming".

    A tip: the actually measured record shows irrefutably that there has been a "plateau".

    Those are the facts, josullivan58.  Enjoy the good news rather than despairing!

  • Bet with JCross

    Hi John,

    Back to our bet.

    You wrote: "In regards to our bet, what I propose is exactly what I said.  We use 1998 as the benchmark.  We use either the GISS dataset or the Hadley with some sort of allowance made for its exclusion of the polar region - your pick.  We use the annual temperature (meteorological year) for 2020.  If it is larger than 1998 I win, if it is smaller then you win.  In the case of a tie, we average the 2019 and 2020 and see how that compares."

    Allowances and adjustments for this or that are complicated.  Let's stick with a simple, easily understood published record.

    I would agree to the Hadley annual globally averaged surface land and sea anomaly as it is reported. Presume this is what you mean when you say "meteorological year".  If not, please explain.  For the year 1998 this was +0.515C.  Every year since then has been cooler, with 2005 the closest at +0.479C.

    You apparently believe this is going to change and future temperatures will again become warmer.

    You probably have the long-term odds on your side, while I may have the shorter-term record in my favor.

    I was once told by my grandfather, "Don't ever bet on the weather."  Looks like I am going against this sage advice.

    The Hadley anomaly is currently based on a baseline period, which I believe is the average from 1961 to 1990.  If this should change in the future or if Hadley make any other changes that change the reported anomaly in either direction, we would need to figure out what impact this has on the anomaly as published, and correct accordingly.

    We agreed that the amount of our bet would be $1,000 (US).

    So if we can agree on the basis for our bet, we can then start looking at the mechanics and details of setting it up.

    That might best be done offline.

  • Facts are facts, TP

    Hi TP,

    You wrote: "Let's go ahead and for the sake of argument, say that I don't `understand' the record, but that I would like a climatologist to explain it to me."

    By all means , TP, if you have problems with simple data sets or how to plot them into Excel and draw trend lines, etc., get someone to help you.  Doesn't necessarily need to be a "climatologist" (whazzat?).  Any high school math teacher can help you.

    Some facts:

    Over the last 25 years of the 20th century there was a global warming trend of 0.175C per decade.  This trend is referred to by IPCC.  On this basis, IPCC predicted a warming of 0.2C per decade for the next 2 decades.

    All four temperature records show that there has been a "plateau" in global warming over at least the past seven years (since 2001).

    Three of the four records show a cooling trend (Hadley, RSS, UAH), and the fourth (GISS) shows a flat trend.

    Hadley: -0.108 deg C per decade
    RSS:   -0.060 deg C per decade
    UAH:   -0.004 deg C per decade
    GISS:  0.00 deg C per decade

    Now TP, these are not opinions.  They are observed facts, out there for one and all to see.

    Even Dr. Pachauri has said he will look into the causes for this apparent "plateau", so he is not denying the fact that it exists.

    Sorry, TP, the facts are the facts, even when they do not directly support the theory.

    The lead article here says the WMO believes the rest of this year will continue to be cold. Are they right?

    I am not saying that this 7-year slight cooling trend will continue beyond 2008.  Who knows what will happen?  The "climatologists"?  Maybe.  Maybe not.

    IPCC has used the surface temperature record, despite all its "warts" (such as the UHI), uneven coverage, and uncertainties, rather than the tropospheric record as measured by satellites (and to a much smaller extent) by weather balloons.

  • When the facts don't fit the theory...

    Hi John,

    The Lynas article is an excellent example of "bending the facts to fit the theory".  
    ·    Our theory tells us it should be warming.  
    ·    The observed facts show us it is not warming.  
    ·    Something must be wrong with the facts; let's adjust them to fit our theory.

    Another good example of this approach is hidden in the IPCC Chapter 4 FAQ section to rationalize the mid-century cooling trend from around 1940 to around 1976 as having been caused by "anthropogenic aerosol emissions". (But let's not get into that discussion here; it is a whole new chapter.)

    I have just presented the fact, based on the observed temperature records of Hadley, UAH , RSS and GISS, that there has been a "plateau" in the global temperature trend.  First I started the trend with 1998, and it showed no temperature increase over the past 10 years.

    Another blogger criticized the choice of 1998 as the starting year, since it was a record warm year and, thus, introduced an "artifact".

    So I re-ran the data starting in 2001, the "first year of the 21st century".

    Three of the four records show a cooling trend (Hadley, RSS, UAH), and the fourth (GISS) shows a flat trend.

    Hadley: -0.108 deg C per decade
    RSS:   -0.060 deg C per decade
    UAH:   -0.004 deg C per decade
    GISS:  0.00 deg C per decade

    Now John, these are not opinions.  They are observed facts.

    You raise all sorts of irrelevant side issues (correcting for the length of the month, R2 factors).  You tell me that you have established that the "R2 is .004" (apparently using a GISS annual data set).  I explain to you that in the case of the monthly Hadley set the "R2 is .0125".

    So by now, we are beginning to see how this discussion is developing.

    I bring facts, i.e. all 4 records show no global warming since January 2001.

    You do not refute these facts.

    How can you, they are out there for one and all to see?

    Even Dr. Pachauri has said he will look into the causes for this apparent "plateau", so he is not denying the fact that it exists.

    Instead, you counter with nit picks and obfuscations, treatises on statistics, blah, blah.

    Face it, John.  The past 7 years show no global warming, even a possible cooling.

    Whether this is the start of a longer term cooling cycle (as we have experience before, most recently from around 1940 to around 1976) or whether warming will again take over, and, if so, when this renewed warming trend will start is anyone's guess.  

    I am not going to make any predictions, and I would advise you to stay away from prophesies, as well.  

    As Warwick demonstrated pretty effectively, predictions can come back to haunt you.

    So that just leaves us with our bet to settle.

    You started the whole topic of a bet with: "In fact I am confident enough to offer you a bet that in - say - 2020 the annual temperature will be more than it is this year (2008)."

    You "cherry pick" 2008. The first months of 2008 have been unusually cold, as confirmed by all temperature recors, with snow in southern China, the Middle East, record snows in parts of North America, etc.  Even Grist tells us that the "World Meteorological Organization is expecting global temperatures to drop this year thanks to a strong La Niña."
    http://www.grist.org/news/2008/04/04/world_temp/index.htm ...

    So I respond to your "cherry pick" with one of my own: 1998, the year that the global warming trend of the late 20th century ended, and you agreed, "Regarding the bet, yes, I am willing to take it up with the year being 1998."

    You come back with, "First, I gave in to you and instead of using an average temperature for the last - say 10 years, you got to cherry-pick the year with the largest el-Nino of the century."

    Now you object to the use of the Hadley record (rather than GISS). I explained to you why recent events had shown that GISS may be unreliable in some areas, so that is why I usually prefer the Hadley record for global surface temp.

    Now you tell me the Hadley "global" number is not really as "global" as the GISS number.

    Lots of waffling here, John.

    State what you want to bet on and which parameters will be used.

  • Fatal flaws for Greyfalcon

    Hey GF,

    Please address the "fatal flaw" of the AGW theory, Greyfalcon, as I pointed out.

    It is every bit as convincing as the "fatal flaw" of Svensmark's theory.  Right?

    If not, why not?

  • Tasermons Partner should check the record

    Hey TP,

    Check the record.

    You are smart enough (I hope).

    Believe me, you do not need an "established climatologist" to tell you what the record shows.

    It is painfully obvious.

    Globally averaged land and sea surface temperature according to the Hadley Centre have cooled over the past seven years, i.e. over the period from January 2001 to February 2008.

    But, hey, I'm not saying this is part of a 100-year or 1000-year trend.  It's just the facts for now.

    Got it?  Really not that hard to grasp, TP.

  • Bet with JCross

    Hey JCross,

    We have obviously reached an impasse on the most recent global temperature developments and trends.

    Let's talk about the "bet" you proposed.

    "I am confident enough to offer you a bet that in - say - 2020 the annual temperature will be more than it" was in 1998, based on the Hadley annual record of globally averaged land and sea surface temperature anomaly. (Year changed from 2008 to 1998 and Hadley record rather than GISS.)

    My record tells me the Hadley anomaly in 1998 was +0.526C.  Do you agree?  If not, which number do you propose?

    Let's make sure we also establish what this "anomaly" is based on.  As I understand, it the "baseline" here is the base period 1961-90. Do you agree?

    If Hadley changes their "baseline" period in the future (such as "20th century average" or something else) we would have to make that adjustment.

    Now, I am not a rich man, but I would be willing to put $1,000 (U.S.) on the line.

    We could deposit this $1,000 in a bank somewhere, with our "bet contract", so that in the year 2020, if the globally averaged land and sea surface temperature anomaly compared to the base period 1961-90 (according to the Hadley annual record) is higher than 0.526C, you win; if it is lower, I win.

    Would you agree?

    Then all we have to do is draw up the contract and select the bank to "hold the money".

    Let's move to the next step, JCross.

    Best regards,

    Hi John,

    You asked: "How did you adjust for the month length."  I did not.  Can you show me how big an error this has introduced?

    My R2 was .0125 not .004 as you say it was in your set of data.

    1998 as the start year.  Great!

    But I prefer Hadley unvarnished monthly data averaged over the year (they also report the annual average, as you know) to anything GISS puts out, in view of their "odd man out" status and the problems we have seen recently with "fudged" GISS records.

  • Some "fatal flaws" for Greyfalcon

    Hi Greyfalcon,

    Svensmark's lab results showed an observed link between cosmic rays and cloud formation.  Whether the CLOUD study at CERN will confirm this, is a matter of conjecture at this point.

    Critics of Svensmark's theory point out that, while it may have shown fairly good correlation with global temperature in earlier years the link after around 1980 is poor. This is often referred to as the "fatal flaw" in Svensmark's theory.

    This argument may be valid, but it raises the question:

    Is there an actually observed link between atmospheric CO2 concentration and global temperature?

    The Hadley Centre has a published record of "monthly globally averaged land and sea surface temperature" that goes back to 1850.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    Actual measurements of atmospheric CO2 concentration only started in 1958.
    http://www.esrl.noaa.gov/gmd/ccgg/trends/co2_data_mlo.htm ...

    IPCC estimates based on ice core readings go back to pre-industrial times. These show an estimated gradual increase from around 285 ppm in 1850 to 315 ppm in 1958, when actual measurements started.
    http://ipcc-wg1.ucar.edu/wg1/Report/AR4WG1_Print_SPM.pdf

    CO2 concentrations have risen steadily over the entire period.  The rate of increase has also accelerated slightly over the period, particularly following WWII.

    Global temperatures have risen over the period, but a closer look at the record shows that this has been anything but steady.

    Between 1850 and around 1860 there was a very slight cooling trend.  

    This trend reversed to a warming trend for the next 20 years until around 1879 (at +0.196C per decade this period shows the highest decadal rate of increase since records have been taken). There was essentially no increase in CO2 during these "horse and buggy" years.  

    This was followed by another cooling trend until around 1906 (-0.047C per decade).  

    Then came another warming trend until around 1940 (+0.161C per decade), followed by a slight cooling trend until around 1976  (-0.02C per decade), during the post-war boom period of rapid increase in CO2

    Following this, we had a trend with the second highest decadal rate of increase (+0.175C per decade) from 1976 to around 1998.  This trend occurred during a period of rapid CO2 increase and has gotten a lot of attention as evidence of anthropogenic greenhouse warming (AGW).

    Since the end of the 20th century, this rapid warming trend has stopped.  Over the seven-year period since 2001 there has actually been a very slight cooling trend, despite the continued high rate of increase of CO2.

    So it appears that last 25 years of the 20th century provide the only observed link between CO2 and temperature.

    The immediately preceding period had CO2 increase with cooling.

    The immediately ensuing period since the start of the 21st century shows slight cooling with high increase in CO2.

    The period from 1860 to 1879 showed the highest rate of temperature increase of all periods measured, with essentially no CO2 increase whatsoever.

    In summary, the actually observed data show that there does not appear to be a very "robust" link between atmospheric CO2 concentration and global temperature.

    Is this the "fatal flaw" in the AGW theory?

    Just some food for thought, Greyfalcon.

  • Greyfalcon gets it wrong again

    Hey Greyfalcon,

    You wrote to Black Wallaby: "Last I checked, Svensmark admitted that IF there is any effect from cosmic rays, that it's so inconsequential that it falls within the margin of error."
    http://news.bbc.co.uk/2/hi/science/nature/7327393.stm

    You got it wrong, Greyfalcon.  Better check again.

    Nowhere in your linked BBC blurb does it say "Svensmark admitted that IF there is any effect from cosmic rays, that it's so inconsequential that it falls within the margin of error."

    Some other guy named Sloan from the University of Lancaster made that claim and Svensmark replied that Sloan "failed to understand how cosmic rays work on clouds".

    Just to clear up an apparent misunderstanding on your part.

  • Agreeing to disagree with JCross

    Yep, looks like we will have to agree to disagree.

    Three records (Hadley, RSS, UAH) show cooling from January 2001 to February 2008.

    The fourth record (GISS) show a flat trend.

    Those are the facts, John.

    They are based on the monthly values as reported by each record.

    Taking annual values introduces an unnecessary time lag.  Stick with monthly figures, John.  You will get better trend info over shorter periods that way.

    Warwick points out where IPCC model projections have been poor.  This was true in earlier IPCC reports.  Whether it continues to be true in the latest report remains to be seen.  I observed that the latest IPCC projection of 0.2C per decade warming for the "next 2 decades" isn't starting out that way, but, who knows what will happen?

    To your offer of a bet: "In fact I am confident enough to offer you a bet that in - say - 2020 the annual temperature will be more than it is this year (2008).  So I don't think it is a new flat or cooling trend - do you?"

    How about replacing 2008 with 1998?  Bet still on?

  • Nice blogging with you, MNG

    Hi MNG,

    You sure used a lot of nice prose to say absolutely nothing about the observed recent "plateau" in global warming.

    Since someone said it would be introducing an "artifact" by starting the most recent decade with the year 1998, I also started the trend with the year 2001 (coincidentally the first year of the 21st century).

    No matter how you slice it, it is apparent that the warming trend of the latter part of the 20th century has stopped and flattened out or even reversed itself to a cooling trend over the past 10 years.

    These are just observed facts.  No fancy prose needed.  No "climate expert" needed to rationalize why this has occurred.  Just the facts, that's all.

    And you have been unable to refute these facts.

    The lead article on this thread predicts that this cooling trend will continue through 2008 (whether this is correct or not is anyone's guess).  

    Believe Black Wallaby has answered your rather strange remark on "tiny data subsets", so there is no point in my repeating it all.

    Now to the future.

    Who knows what the temperature trends will be going forward (let's say for the next decade)?

    I do not.  You do not.  The IPCC does not.   WMO Secretary-General Michel Jarraud does not.  "2,500 climate experts" do not.  A whole lineup of supercomputers does not.  Check the "Farmers' Almanac".  They have the best track record to date.

    There is an old farmers' saying in German:
    "Wenn der Hahn kräht auf dem Mist
    Dann ändert das Wetter, oder es bliebt wie's ist."

    (When the rooster crows on the dung heap, the weather will change, or stay as it is.)

    I think our discussion on this topic has ended, but it was nice chatting with you.

    Max

  • Why is JCross silent?

    Hi John,

    You have been kind of quiet for a while.  Is everything OK?

    Since all records show that global warming stopped in January 2100 (the official beginning of the 21st century), do you have any comments?

    Do you believe this is the beginning of a new flat or cooling trend or just a temporary 7-year "blip" in the curve?

    Appreciate your thoughts on this.

    If you prefer not to comment, I can understand.

  • GreyFalcon's forecast

    Hi Greyfalcon,

    Thanks for your weather (`scuse me, climate) forecast.

    So maybe 2008 will continue the observed cooling/flat trend of the past seven years. That will make it an eaight-year "blip" in the curve.

    And I really hope you are right that it will start warming again (or at least not continue to cool) after 2008.

    But what if you are wrong?

    Could happen.  Happens to the best of guys when they are forecasting the weather (`scuse me, climate).

  • 21st century warming?

    Hi MNG,

    BTW January 1, 2001 is the official beginning of the "21st century" (Wikipedia), so it is accurate to say that all four temperature records confirm that there has been no trend of global warming in this century, right?

    (Maybe one should add a "so far" disclaimer, to be on the safe side.)

    But it does raise a question about the sub-headline of the lead article here: "Global temps may drop this year, but, alas, world still warming"

    Hmm... Just something to think about.

    But I have enjoyed our exchange on this and other subjects, and you are a nice guy.

  • One more point for JCross

    Hi John,

    I raised the question regarding when the recent warming trens stopped (if not in 1998).

    Going through all four records, they all pretty much show that the most recent global warming trend stopped in 2001.

    The linear trend of the 4 records from January 2001 to today is:

    Hadley: -0.108 deg C per decade
    RSS:   -0.060 deg C per decade
    UAH:   -0.004 deg C per decade
    GISS:  0.00 deg C per decade

    So maybe 2001 is when the warming trend stopped (for now).

    Whether these past seven years are the beginning of a new cooling (or flat) trend or whether they just represent a "blip" in the curve is anyone's guess today, and I do not want to make any forecasts.

  • Message for JCross

    Hi John,

    Let's see if we can continue our discussion on the global temperature record in good faith and resolve any differences we may have.

    You have written that you generally agree with points 1, 2 and 3:

    1. that temperatures have been in an overall slow rising trend since 1850
    2. that there are multidecadal swings from slight cooling to warming
    3. that the recent warming trend from 1976 to 1998 is not unusual when compared to earlier warming periods, which occurred prior to AGW

    You did put in the caveat "although I would say that the recent warming trend does not end in 1998. Depending on which data set you take there are years since 1998 which are warmer than 1998."

    Which years are warmer than 1998 in which record?

    If I go back to the source of the data, I see that the "odd man out" is GISS.  All the other records show no years after 1998 that were warmer than 1998.

    The past 120 months show a flat linear trend in three out of four records (GISS is "odd man out" again, with a slight warming trend).

    The past 60 months show a cooling trend in all four records (including GISS).

    So, in light of the observed records, when would you say that the recent warming trend ended, if not in 1998?  Maybe we can agree on a date here.

    We were still not in agreement on two points:

    1. that the impacts of various "forcing" components on the global average temperature are not as simple as IPCC would have us believe
    2. that the ability of climate models to predict temperature trends is limited

    Believe we agreed with your statement on point 4:
    "I would not agree with your statement that the IPCC thinks the various forcing components are simple.  There are a large number of factors involved and this is an active area of research."

    I did not mean to imply that IPCC states that forcing components are "simple".  They do however present a rather simplistic view on which forcing factors play the largest role in climate change, and these are identified as anthropogenic greenhouse factors.  These are also the principal factors used in projecting future climate change, using climate models with various scenarios and storylines.

    My point was that there must be something fairly significant at work here other than just AGW, since the correlation between atmospheric CO2 (plus other GHG) and temperature is not really that apparent when observed over the entire temperature record.  

    What are these as yet unidentified forcing factors that caused rapid warming in the late 19th century and early 20th century, mid-20th century cooling and the current slowdown (or reversal) of warming?  Are we missing something basic here?

    Point 5 is simply that the climate models have not shown a very good "hit rate" in the past on projecting temperatures (there have been several "global warming scorecards" published on this).  Here is one:
    http://www.warwickhughes.com/hoyt/scorecard.htm

    My direct observation was that the models projected warming at a decadal rate of +0.2 degrees C for the early 21st century (higher than over any extended period to date), yet the current trend is actually flat or even cooling.

    You have written, "In regards to the climate models, I have not yet entered a discussion on this topic that has come to any rational conclusions."

    I can live with that statement.  The danger with any computer models is the old GIGO problem.

    Someone once observed that had we had supercomputers back in the 1860s, when urban centers in England started exponential growth with ever-increasing "horse buggies", someone could have projected that within 100 years (by 1960) Manchester would be covered by two meters of horse manure.

    So where are we still in disagreement?

    Max

  • Response to JCross

    Hi John,

    You asked me, "From what you said, you appear to have used the monthly data, if so may I ask how you corrected for the fact that different months have different lengths?"

    Yes, I used the monthly data.  This gives the most representative information available on what is really going on, don't you agree?

    Tell me, JCross how does the fact that "different months have different lengths" influence the trend in your opinion?  Is this a major factor?  If so, how?  How would you correct? lease give details.

    You wrote: "In regards as to whether GISS is the "odd man out" there may be an argument for it, but the link you posted does not make that argument"

    Sorry, John, if you really take the time to read it, you will see that it does indeed address the issue why GISS does not agree with the other three records.

    But the main problem many people have with GISS is that it has been shown to have faulty records (i.e. hottest U.S. year 1998 vs. 1934), other "ex post facto" adjustments made to the record, and people have frankly become suspicious relating to the objectivity of James E. Hansen, since he has become an activist, rather than an objective scientist on the U.S. taxpayer's payroll, who is being paid to give the U.S. taxpayer unbiased input on temperature trends.

    My advice to you (if you want some semblance of objectivity):  rely on the other records first; they have a higher probability of being "objective" than the GISS record.

    But, in any case, you cannot deny that ALL records (even the somewhat suspect GISS record) show a significant slowdown (or an actual stop) of "global warming" since 1998.

    Now you may point out that some folks may have a  problem with the fact that the last 10 years (or decade) started in 1998.

    They insinuate that it would be "unfair" to start the record in 1998, because this was an unusually warm year, calling this an "artifact".

    Interestingly enough, none of these people had problems with this back in 1998, when this "unusual warmth" was being used to prove that AGW was causing accelerated warming.

    So let's only look at the record for the past five years (2003-2008), instead of the past 10 years.

    We find that:

    The Hadley record shows a cooling trend of -0.28 degrees C per decade
    The RSS record shows a cooling trend of -0.24 degrees C per decade
    The GISS record shows a cooling trend of - 0.11 degrees C per decade
    The UAH record shows a cooling trend of -0.09 degrees C per decade.

    Again, 5 years (or even 10 years) do not constitute a new long term "trend", but they do give us reason to question the IPCC projections of 0.2 degrees C per decade future warming over the first two decades in the 21st century.

    Has global warming really stopped?

    It certainly may look like this is the case, but I agree that the jury is still out on this question.

    Personally, I am not too happy that this appears to be the case, and I am actually hoping that those who predict a reversal of the current trend are right.  I would much rather see a bit more warming than a real cooling trend.

    We definitely do NOT need another Little Ice Age; much better would be a slight warming to get us back up to the temperatures of the Medieval Warm Period or, even better, the Roman Optimum.

    What do you think?

  • A message to Sarah81

    Hi Sarah,

    While I fully agree with your premise that "it make sense to be proactive", I can also endorse Black Wallaby's remark to you.

    The 4 million deaths annually attributed by the WHO to lack of clean drinking water and electrical power among the hundreds of millions of poorest individuals of this world is a horrible problem, as you will surely agree.

    The 20,000 individuals that lose their lives from "extreme weather events" (including extreme cold) annually are an insignificant drop in the bucket in comparison.

    The real problem here, Sarah, is that "global warming" is a "rich man's (and woman's)" problem involving billions of dollars of research grants, etc. and potentially hundreds of billions of dollars in carbon taxes or cap and trade schemes, ( i.e. really big bucks) being shuffled around by politicians, bureaucrats, carbon trading companies, hedge funds, etc.  This translates into big bucks for some already rich folks.

    The problems of the poorest who are dying every year from the lack of clean drinking water or electrical power to cook without inside burning of wood, dung, etc. is less "sexy", because it is a "poor man's (and woman's) problem.  No "big bucks" being shuffled around by already well-to-do individuals.  No big PR or media campaigns. No big bucks to be made by already well-to-do folks.

    My suggestion would be: let's solve the real problems first, before we get distracted by the virtual computer generated "maybe future" problem of possibly alarming "global warming".

    What do you think, Sarah?

  • 3 out of 4 records say warming stopped in 1998

    Hi John,

    Since there appears to be a significant difference between the GISS record and the other two (Hadley and UAH), I checked the fourth record (RSS).  It shows an essentially flat trend from 1998 to today, agreeing with Hadley and UAH.  It appears that the GISS record is "the odd man out here".  

    There has been some discussion of why this may be so on the site below:
    http://wattsupwiththat.wordpress.com/2008/02/27/a-look-at ...

    The most significant thing is that none of the records show anything close to +0.2 degrees C per decade (as projected by IPCC). This trend was true from 1976 to around 1998, but since 1998 one record shows that the warming trend has slowed down significantly and the other three show that it has stopped.

  • Agreeing with JCross

    Hi John,

    Believe we can truly agree on one thing:  Your statement that "Agreement is a tricky thing".

    Now I have been using the Hadley surface record and comparing with the UAH satellite record, but your totally different result from the GISS record made me curious, so I went back to the source of the data.

    If I plot all the monthly anomaly readings from January (or March) 1998 to February 2008 (the last reading available in all three records), I get:

    Hadley: 0.00 degrees C per decade
    UAH: +0.01 degrees C per decade
    GISS: +0.08 degrees C per decade

    Nowhere do I see anything even close to +0.2 degrees C per decade.  This value may have been the "generally accepted value" at one point, but it is no longer the actually observed value.

    Am I missing something here?  Did you include all the most recent data points in your analysis?  Did you use "12-month average" values rather than the monthly points?  How can you explain such a major difference?

    Now to the trend: I have not said that the latest decade represents a "new long term trend".

    It is less than half as long as the previous 22 year trend from 1976 to 1988, so we will have to wait and see.

    Follow the money trail indeed.

    How about 10-12 billion $ per year globally today on AGW (50% in USA).

    AGW really has become a "multibillion dollar big business".

    And just wait until the hundreds of billions from carbon taxes and cap and trade schemes start really kicking in.

    Robco1 is right: Follow the money trail.

  • MNG is waffling

    Hey MNG,

    Do you realize that you are avoiding the issue here?

    Rather than talking about what is an "IPCC graph" and other obfuscations, just do yourself a simple favor and actually download the Hadley Centre raw data.  It is actually very easy for anyone to do, without the need of expert opinion or advice from climate experts.

    You made a statement: "Grist readers should be aware that there is more than one "data set" of temperature data in use by climate researchers.  Hadley and NASA GISS are two of them.  The data sets apparently don't precisely agree with each other and each data set has its supporters and detractors."

    Duh!  This is a rather obvious statement that has nothing to do with the issue here. UAH is another data set.  This also has nothing to do with our discussion.

    You will see, MNG, that all of these "data sets" agree that the temperature trend from January 1998 to February 2008 was flat. "Flat" means no increase in temperature for 10 years (= 1 decade). Is this difficult to grasp?

    Just admit this fact and then we can move on.

    Otherwise, bring evidence why this is not correct.

    This is called "put up or shut up".

    "Hoping to be nice, anyway."

  • Almost in agreement with JCross

    Hi John,

    Thanks very much for your reply.

    Objectionable sentence deleted.

    Glad we could agree to the first three points of my conclusion.

    You wrote: "I would say that the recent warming trend does not end in 1998. Depending on which data set you take there are years since 1998 which are warmer than 1998".

    What will happen in the future is anyone's guess.  The warming trend may again accelerate, or it may turn down into a real cooling trend.  Nobody knows, and I certainly do not want to make any predictions.

    But for the past trend I have used the Hadley record, which shows that 1998 is the record warmest year, as does the UAH satellite record.  Which record do you feel shows which years to be warmer than 1998?

    Do you feel that the Hadley (or UAH) record somehow is not representative of what is actually going on, and, if so, why not?

    The rapidly warming trend from 1976 to 1998 is irrefutable.  There was a linear decadal warming trend of somewhere between 0.14 and 0.18C per decade over this 22-year period, depending on which set of data is taken.  I used the Hadley trend of 0.175, which I believe is also the basis used by IPCC.  

    But whether or not 1998 was the all time record year, the leveling off since 1998 is also irrefutable, based on all records.

    Let's not fall into the trap of "my record is better than your record", but let's concentrate on the decadal linear rate of change over the period 1998 through February 2008.  This clearly shows a flat trend, which is the point I was making. I believe this is true no matter which record is used.

    You stated: "I would not agree with your statement that the IPCC thinks the various forcing components are simple.  There are a large number of factors involved and this is an active area of research".

    I agree with your statement.  I do not believe that "IPCC thinks the various forcing components are simple".  My point was that the impacts of various "forcing" components on the global average temperature are not as simple as IPCC would have us believe (i.e. in its emphasis on anthropogenic CO2 as the principal driver of climate change).  

    But I am glad we can both agree that there may be other very important factors that are still unknown to us all that are affecting global temperature trends and that the temperature record shows that there is something else going on besides just AGW.

    And we apparently do not disagree basically on the ability of climate models to predict temperature trends accurately since you say "I have not yet entered a discussion on this topic that has come to any rational conclusions".

    So where do we actually disagree?

    We may be closer to agreement that we both thought at the onset.

    Appreciate your feedback.

  • Go to the source, MNG

    Sorry, MNG.  You have not explained why:

    The Hadley trend from January 1998 to February 2008 is flat.

    The Hadley record from January 2000 to February 2008 shows a warming trend of +0.05C/decade.

    The Hadley record from January 2001 to February 2008 shows a cooling trend of -.11C/decade.

    Go to Hadley, the source of the data, MNG, not to a Gristmill graph or to an IPCC report. These will only confuse the issue.  

    This is what I have advised TP to do, but he has not done so. Maybe it is because he knows full well what the data show.

    The data are the data and that is what they tell us has happened over the past decade including the most recent data points.

    It's actually quite simple.

    The trend has been flat for the past decade.

    I am still awaiting your comments on the actually observed temperature record per my earlier post.

    If you have nothing to say, I can understand that. It could be unpleasant to admit that the observed link between temperature and human CO2 emissions is tenuous.

  • TP is waffling but refuses to face the facts

    Hey TP,

    Don't be impolite and call me "dummy".

    Just get someone who can work Excel to download the Hadley temperature anomaly figures from January (or if you prefer March) 1998 to February 2008 and put in a linear trend line.

    YOU WILL SEE THAT THE GLOBALLY AVERAGED SURFACE LAND AND SEA TEMPERATURE ANOMALY TREND HAS BEEN FLAT FOR THE PAST DECADE.

  • A look at global temperature facts for JCross

    Here is one for JCross, who has recently shown his face on this site.

    Hi John,

    As one who is evidently concerned about climate change and its impacts, I would appreciate your comments on the statements below.

    If you have no opinion, or if you are in agreement, you do not really need to reply.

    There has been a lot of "hoopla" lately about "global warming".  The latest records show that it has essentially stopped over the past 10 years, which skeptics are eager to point out, but supporters of the global warming hypothesis are crying "foul".  It has not really stopped, and we are still at the highest levels of temperature anomaly today, therefore global warming is still a very real and apparent threat to humanity, the environment and our planet.

    So let us see if we can cut through the hype from both sides and look at some facts.

    Since global temperature records have been kept (based on the UK's Hadley Centre), and we have been emerging from the Little Ice Age, there have been several multi-decadal cycles from warming to cooling, with an overall slight warming trend.
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    Period    Trend    Years    Increase    
    1860-1879    0.196    20    0.39    
    1879-1906    -0.047    27    -0.13    
    1906-1940    0.161    35    0.56    
    1940-1976    -0.020    36    -0.07    
    1976-1998    0.175    22    0.39    
    1998-2008    0.000    10    0.00    
    Trend is linear decadal trend in degreesC/decade
    Increase is linear change over period in degreesC

    Between 1850 and around 1860 there was a very slight cooling trend.  

    This trend reversed to a warming trend for the next 20 years until around 1879 (the highest decadal rate of increase since records have been taken).  

    This was followed by another cooling trend until around 1906.  

    Then came another warming trend until around 1940, followed by a slight cooling trend until around 1976 (this one has been very briefly rationalized by IPCC, without any supporting evidence, as having been caused by anthropogenic aerosol emissions).  

    Following this, we had a trend with the second highest decadal rate of increase from 1976 to 1998.  This trend has gotten a lot of attention as evidence of anthropogenic greenhouse warming (AGW).

    This trend appears to have reached a "plateau" from 1998 to today, in sharp contrast to the IPCC projections from model studies, which predicted a record rate of increase of 0.2 degrees C per decade for the first two decades in the 21st century.

    The longer-term trend over all these cycles has been an increase of somewhat more than 1 degree C over the 150+ years of measurement.  

    In its TAR (2001) IPCC reported an increase over the 20th century (1901-2000) of 0.6 degree C.

    If one "jiggles" the definition of the 20th century (as IPCC did in its 2007 SPM report) to replace the 1900-1906 cooling trend with an essentially flat trend from 2000 to 2006, one can show a 100-year increase of 0.74 degrees C.

    Interestingly, the highest decadal rate of increase occurred over the 20-year period from 1860 to 1879, in the "horse and buggy" days long before AGW was a problem.  

    The multidecadal cycles are apparent in the record, as is the underlying warming trend over the entire period.

    Whether or not the past 10 years are the beginning of a new "flat" or cooling cycle remains to be seen.

    What is apparent, however, is:
    ·    that temperatures have been in an overall slow rising trend since 1850
    ·    that there are multidecadal swings from slight cooling to warming
    ·    that the recent warming trend from 1976 to 1998 is not unusual when compared to earlier warming periods, which occurred prior to AGW
    ·    that the impacts of various "forcing" components on the global average temperature are not as simple as IPCC would have us believe
    ·    that the ability of climate models to predict temperature trends is limited

    John, I would appreciate your comments on the above, if you have any.

  • A followup for TP

    Hi TP,

    Once you have absorbed the fact that the temperature trend over the past decade has been flat, you may wish to check out my other post covering longer term trends and fluctuations.

    You won't find much about these in the IPCC reports either.

    But follow my advice. Eliminate the "middle man".

    Go to the SOURCE of the data, not to IPCC, if you want facts on global temperature trends.

  • Go to the source, Tasermons Partner

    Hey TP,

    You wrote: "Please provide a link to the section of the latest IPCC report that indicates that temperatures have remained flat durin' the first 6 years of this century to verify your claims."

    I am not talking about the "first 6 years".  I am talking about the latest decade, i.e. 1998 to 2008.

    The IPCC report?  Duh!

    Of course they have not brought anyone's attention to this fact.  

    You need to go to the SOURCE of the data, in this case the Hadley record of the globally averaged land and sea surface temperature anomaly:
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    Then you need to download the data for the period January 1998 to February 2008.

    You need to plot this actually observed temperature trend into Excel and then put in a linear trend line.

    You will see that the trend is flat (as I am sure Dr. Pachauri is fully aware, since it is his business to be aware of what is going on in "global temperatures").

    It's not too hard to do this to convince yourself of what is REALLY going on out there, TP. If you are not able to do these steps yourself, get someone who knows how to work Excel to do it for you.

    Just try it, and you will see that there has been a "plateau" since 1998.  

    And Pachauri has said he will let us know the reason for this observed "plateau"

    Get it?

  • Silly proposals

    Hi MNG,

    There was an April Fool's joke recently on another gist thread.
    http://gristmill.grist.org/story/2008/3/31/155730/362

    Believe you also saw it and reacted.

    It was interesting how many people thought the suggestion (of wiping out all penguins by relocating the allegedly threatened and "overheated" polar bears to Antarctica) was for real.

    But it just shows how ridiculous proposals get made to "solve" a possible (but maybe unlikely) future problem by creating a certain immediate problem.  

    Many of the "get rich quick" carbon sequestration proposals of injecting CO2 into the oceans or into permeable geological formations (rather than leaving the CO2 in the atmosphere, where it is a natural trace component and the source of all life on this planet) are out there for real, not as April Fool's jokes.

    One proposal calls for "sequencing the genomes" of microbes that produce fuels such as methane and hydrogen or aid in carbon sequestration, to allow an evaluation of their potential use to produce, for example, methane or hydrogen from either fossil fuels or other carbonaceous sources, including biomass or even some waste products.

    Another calls for capturing the CO2 with lime.  Another one (probably a joke) calls for covering the planet with concrete, which will gradually absorb CO2 as it cures and ages.

    Now I am certainly not against developing new energy efficient technologies or planting new forests and stopping rampant destruction of tropical rainforests, etc., but I believe that there are some truly hare-brained schemes out there.  

    Why do such silly schemes even pop up?  

    Wikipedia gives us a clue when it tells us, "This concept of CO2 sinks has become more widely known because the Kyoto Protocal allows the use of carbon dioxide sinks as a form of carbon offset."

    Oops!

  • Thoughts on the AGW debate for MNG

    Hey MNG,

    Just read your well-expressed thoughts on the contribution of the various threads to the ongoing debate surrounding anthropogenic global warming, and I admit that I agree with almost every single point you have made.

    Let me give you one rational skeptic's view on what is going on here to see if we can find any common ground.

    There is an on-going debate surrounding the current AGW "scare" (you may prefer to categorize this as an "awareness" rather than as a "scare", but unfortunately the fear factor has been injected into the discussion, so it is more than just an "awareness").  

    This debate covers not only the accuracy, completeness and objectivity of the "science" supporting the suggestion that humans are causing major changes in climate, but also the veracity and credibility of computer-generated predictions of future changes allegedly arising from these anthropogenic causes and, finally, the political measures that are being proposed in order to mitigate these potential future problems.

    This site (as well as many others) was set up to convey one particular viewpoint.  As can be seen from the lead articles, this site it is clearly supportive of the so-called "consensus" position that anthropogenic factors (primarily the emission of carbon dioxide from burning fossil fuels, etc.) are causing significant changes in our planet's climate, that these will have, on balance, more negative consequences than positive ones on the environment, on mankind and on other species and that these changes could become alarming if something is not done to address the root cause (i.e. human CO2 emissions).

    This view is summarized in the various reports of the IPCC, a UN body that was specifically set up to evaluate the anthropogenic impact on climate and, as a result, has "a dog in the race", (i.e. no anthropogenic impact = no need for IPCC to continue to exist).

    Another premise of many of the proponents of this view is that "the science is settled" (because a majority of climate scientists support a "consensus view"), and it is now time for "action", rather than for further debate. "Action" is vaguely defined, but it goes much further than the very sound steps of conserving energy where possible, eliminating waste and pollution of the environment, etc. (which every rational human being should fully embrace).  In this context, however, "action" means implementing draconian political policy steps (carbon taxes or cap and trade schemes) involving hundreds of billions of dollars being shuffled around by politicians and bureaucrats, hedge funds, carbon trading companies, etc., where a few individuals will enhance their personal and financial power at the expense of everyone else.  These are the steps that many rational skeptics of the AGW scare oppose as unnecessary and ineffective.

    There are other, more alarmists, views, expressed by politicians, such as Al Gore (in his Oscar winning film) and UN Secretary General, Ban Ki Moon, (in newspaper articles warning of imminent inundations) or by scientists turned activists, such as James E. Hansen (in his many publications and "tipping point" testimony before the U.S. congress). These individuals proclaim, "Time is rapidly running out; we must act now or we will certainly be doomed!"  Many of the more vocal contributors to this site support these more alarmist views and believe that IPCC is being far too conservative and lackadaisical in describing the future disaster that awaits our planet.

    There are also many sites, which support the view of rational skepticism and oppose the more alarmist predictions that are floating around (climate audit, etc.).  Individuals supporting both sides contribute to these sites, as well.

    It has been my observation (as I believe it has been yours) that the discussion of these topics by individuals who hold different views is, in effect, a debate of the issues.  Each side states its arguments, premises and conclusions and in some (rare) cases finally agrees on a point of view that both parties can embrace.  Undoubtedly, both sides can learn from such a discussion, as you have pointed out.

    You point out: "But recently some of the threads have drifted quite far from that style, toward "winning of arguments" instead of exchanging information or perspectives".  Yes, MNG, there is a "debate" going on, and the point of a debate is for each participant to listen to the opponent's arguments and premises, "get his/her points across" and, yes, in the end to "win the argument".

    "Winning the debate" would appear to be a natural tendency when topics are discussed that could have far-reaching consequences.  

    It becomes especially true when emotions are involved.  In a debate the appeal should be to reason rather than to emotion.  But when an argument is based on the emotion of fear (we will soon all be inundated!) or guilt (we are all at fault for being so disrespectful of our planet and other species!), then the discussion automatically becomes emotional rather than rational.

    There is also the tendency of both sides to "dig in and hold ground" rather than conceding even a small bit.  I have seen this very clearly whenever (for example) a weak point, error or omission in an IPCC report is brought up.  The "IPCC supporter" will go to all extremes to point out that IPCC could not have been in error or could not have intentionally omitted important scientific data from its report.  Semantic distinctions between "made an error" and "cherry picked" become all-important.  (I had a recent exchange on another site on such an issue.)  

    The debate can easily degenerate into a debate of "belief", much like a debate with a religious fundamentalist: "the Bible says so, the Bible is the word of God, so the Bible cannot be wrong" (exchange "IPCC Report" for "Bible" and "2,500 scientists" for "God").

    It is also obvious that the longer an individual exchange goes on the more pointed the debate becomes.

    There are some contributors to this and other sites that start off with "ad hominem" attacks, accusing the other party of being a "troll", a "denier", a "delayer", a "flat-earther", a "stooge" for big oil, etc. and making all sorts of personal insults.  The individuals who fall into this trap have difficulty keeping their personal emotions (anger, fear, disgust, hate?) out of the discussion.

    In this context you remarked that it disappoints you that, "Many of the comments have been characterized by intense disrespect".  I agree that this is disappointing and that we should all avoid making disrespectful comments about the other individual.

    But, MNG, I believe that what is going on is just human nature.  AGW is more than just a theoretical scientific discussion and a "multibillion dollar industry", it is an issue that can and may affect and involve us all.  That is why there are so many sites covering various aspects of this issue out there.

    Fortunately we live in a democratic system, where issues can be discussed openly and dissent is not squashed.

    And that is why the rational debate on these issues must continue.

  • Why MNG is wrong on fear-driven priorities

    Hi MNG,

    In your "fear or desire" post you revealed the basis of your fear.  And the logical fallacies of your argument became apparent.

    Premise 1 is that "We and the other species on this planet are well adapted to the current climate."  This statement implies that we are now in the "goldilocks position of having a `just right' climate", and that any change will more than likely have a negative impact on our own lives, the other species and the environment around us.  This assumption is unfounded.  Certainly history has shown us that "warmer is better" (the MWP was a better time for humanity on balance than the ensuing LIA, when millions faced hardships, economic loss and even starvation due to harsher climate).

    Premise 2 is that "we are causing unpredictable changes", rather than "unpredictable changes are occurring over which we have no control".  This premise is also expressed in your statement "human-accelerated climate changes are expected to happen over the span of decades".

    This is an anthropocentric assumption (i.e. "humans are responsible for climate change"), appealing to the emotions of guilt and fear.  Many natural disasters, starting with the Great Flood and going through to the advancing glaciers and crop failures of the LIA appealed to the emotion of guilt that "the evils of man have caused the Almighty (or Mother Nature) to punish us".  We take ourselves much too seriously here, MNG.  Mother Nature is going to do what she wants to and we do not have much to say or control here.

    Premise 3 is that we can change the course of climate change by "changing our behavior".  This is the most arrogant and foolish of the premises.  In actual fact, regardless of all the hype out there, we cannot change anything.  There are surprises out there that our most educated scientists have no clue about, and there is absolutely nothing we can do about changes in the climate of our planet other than adapt to these changes when they occur.

    Premise 4 is that by enforcing a political course of action (carbon taxes or carbon cap and trade schemes) we can achieve beneficial changes in the future climate of this world so that "future generations inherit a healthy planet".  There is absolutely no valid reason to believe that these actions will ensure a "healthy planet for future generations", or even more importantly, that not taking these actions will risk that future generations will not inherit a "healthy planet".

    There will be a few who benefit enormously both politically and financially from these policies (companies, individuals, hedge funds, politicians), and these individuals and organizations are the ones that are crying out most loudly that these policies are essential for our survival. But, unfortunately, the general public will lose from these policies, in particular those at that are already on the bottom of the economic pyramid.  And, most importantly, there is no reason to believe that there will be any change in future climate.  

    But these policies will certainly take away funding from the more urgent real problems of today.  I can mention just two, both of which cause some 4 million deaths annually in the poorest countries of this world:

  • MNG is right

    Hi MNG,

    Of course you are right in saying we do not know what is going to happen.  By "we", I am including the IPCC and the many scientists out there.

    We do not know for sure that atmospheric CO2 has anything to do with warming (even though IPCC thinks this is "very likely").

    We do not know whether we are now entering the beginning of a cooling cycle, caused by some factor that we also do not know. And we do not know for sure what the effects of a colder climate would be on humanity, although we do have some recent historical evidence that it would not be too positive on balance.

    To say "be cautious" implies that caution is the same as reducing CO2 emissions drastically because we do not know for sure that these may not be causing temperatures to increase, which we do not know for sure could cause sea levels to rises more rapidly than they have been ever since records started and which we do not know for sure could cause an increase in extreme weather events and tropical cyclone frequency and intensity, etc. etc.

    We also do not know whether or not a warmer world would be a better place than today's world, whether higher atmospheric CO2 levels and moderately higher temperatures would not increase plant, forest and crop growth, whether it would enable arid and semi-arid reagions of the world to become green due to improved plant water use efficiency, whether or not there would in fact be fewer extreme weather events and tropical cyclones and fewer droughts, etc. etc.

    To "excercise caution" in the hopes of being able to maintain the current status quo does not make much sense to me, if it includes making a significant sacrifice in our standard of living and in being able to address other, more important problems of this world that the computer generated virtual problem of anthropogenic climate change.

    Just some thoughts from one who is less afraid of an unknown future than you appear to be.

  • Some more on temp for Tarsemons Partner


    Hi TP,

    Here's some more stuff on temperatures that might interest you.

    Since global temperature records have been kept (based on the UK's Hadley Centre), and we have been emerging from the Little Ice Age, there have been several multi-decadal cycles from warming to cooling, with an overall slight warming trend.

    Period    Trend    Years    Increase   
    1860-1879    0.196    20    0.39   
    1879-1906    -0.047    27    -0.13   
    1906-1940    0.161    35    0.56   
    1940-1976    -0.020    36    -0.07   
    1976-1998    0.175    22    0.39   
    1998-2008    0.000    10    0.00   

    Trend is linear decadal trend in degreesC/decade
    Increase is linear increase over period in degreesC

    Between 1850 and around 1860 there was a very slight cooling trend.  

    This trend reversed to a warming trend for the next 20 years until around 1879 (the highest decadal rate of increase since records have been taken).  

    This was followed by another cooling trend until around 1906.  

    Then came another warming trend until around 1940, followed by a slight cooling trend until around 1976 (this one has been very briefly rationalized by IPCC, without any supporting evidence, as having been caused by anthropogenic aerosol emissions).  

    Following this, we had a trend with the second highest decadal rate of increase from 1976 to 1998.

    This trend appears to have reached a "plateau" from 1998 to today, in sharp contrast to the IPCC projections from model studies, which predicted a record rate of increase of 0.2 degrees C per decade for the first two decades in the 21st century.

    The longer-term trend over all these cycles has been an increase of somewhat more than 1 degree C over the 150+ years of measurement.  

    In its TAR (2001) IPCC reported an increase over the 20th century (1901-2000) of 0.6 degree C.

    If one "jiggles" the definition of the 20th century (as IPCC did in its 2007 SPM report) to replace the 1900-1906 cooling trend with an essentially flat trend from 2000 to 2006, one can show a 100-year increase of 0.74 degrees C.

    Interestingly, the highest decadal rate of increase occurred over the 20-year period from 1860 to 1879, in the "horse and buggy" days long before AGW was a problem.  

    The multidecadal cycles are apparent in the record, as is the underlying warming trend over the entire period.

    Whether or not the past 10 years are the beginning of a new "flat" or cooling cycle remains to be seen.

    What is apparent, however, is:
    ·    that temperatures are in an overall slow rising trend
    ·    that there are multidecadal swings from slight cooling to warming
    ·    that the impacts of various "forcing" components on the global average temperature are not as simple as IPCC would have us believe
    ·    that the ability of climate models to predict temperature trends is limited

    Hi TP,

    You wrote: "Just because someone looks into somethin', that doesn't mean they acknowledge it's existence."

    The temperature "plateau" is an established fact, supported by the actual global land and sea surface temperature anomaly record, as measured by Hadley and others.

    All you have to do to confirm this is download the data, plot it in Excel and put in a linear trend line.

    The trend for the past decade has been "flat".

    This is true even if you eliminate the record year 1998.

    It is true if you start with the 21st century.

    Pachauri is well enough informed to know about these things.

    He said he would look into the reasons for this apparent plateau (i.e. "are there natural factors compensating?"), not that he would confirm that it actually exists (since no confirmation or acknowledgement of an established fact is required).

    Whether the past decade constitutes a new trend or is just a 10-year "blip" in the curve is a matter of conjecture and not really pertinent to the discussion at this point.

    IPCC projected linear rate of increase of 0.2C per decade for the first two decades of the 21st century.  So far the first 8 years of the 21st century have been flat.

    Pachauri will let us know his take on what the causes are for this plateau.  Let's see what he tells us.

  • Read more than just chapter 5

    Hi Andrew,

    You started off with the statement to Black Wallaby that there was no paper out there that discussed a positive feedback resulting in higher atmospheric CO2 concentrations due to out-gassing of CO2 from a warmer ocean.  This turns out to have been incorrect based on two links I cited (Hansen, Ahlbeck). So we can lay this argument to rest, OK?

    So now you have moved the discussion to the second topic:
    "I get tired of saying this, but the scientific basis for ocean acidification is in the IPCC report.  I know that the last time I told you to read the IPCC, you reacted angrily ... but I feel strongly that everyone should take responsibility for getting to know the facts themselves.

    Here's a hint: read chapter 5 of the IPCC report.  You can find the entire report on-line at www.ipcc.ch. "

    I don't recall getting angry, Andrew.  Maybe you are thinking about someone else.  I am also surprised that you are getting tired.  But your and my emotional or physical state is another discussion.

    I have read IPCC chapter 5 in some detail, even before you gave me this helpful hint.

    Chapter 5 suggests that the "surface waters of the ocean will become more acidic" (which is actually to say "less alkaline") due to higher CO2 content.  The physical evidence presented for this suggestion in Chapter 5 is not very robust, i.e. a few spot measurements starting in 1985.  According to the data presented, the three measurement locations started measuring around 1985, 1990 and 1995, respectively.

    At the station with the shortest record, pH was actually measured and, from this pCO2 was calculated.  At the other two stations, values of pCO2 and pH were calculated from direct observations of oceanic dissolved organic carbon (DIC, i.e. the sum of CO2 plus carbonate and bicarbonate).  

    The statement is made that "DIC reflect changes in both the natural carbon cycle and the uptake of anthropogenic CO2 from the atmosphere". (This seems to be a rather strangely worded statement, since it would appear that the CO2 uptake by the ocean could be either of natural or anthropogenic origin, as there is no evidence that the small amount of anthropogenic CO2 would be absorbed preferentially to the very much larger amount of natural CO2.)

    The suggestion is made that the change in pH is attributable to the recent uptake of anthropogenic carbon in the ocean.  No physical evidence is presented for this suggestion.

    The assertion is made that: "Changes in DIC between two time periods reflect the anthropogenic carbon uptake plus the changes in DIC concentration due to changes in water masses and biological activity".  No evidence is provided to support this assertion.

    There are calculations of past trends since 1750, but these hardly represent physical evidence, since there are no data from actual observations.

    So, all in all, we have a very limited set of data points in three spots of the vast ocean plus some suggestions and calculations to tell us that the ocean is becoming "more acidic" (sounds a bit more serious than "less alkaline", which would be more scientifically correct) , that this is caused by the uptake of anthropogenic CO2 and that this trend started around 1750 (i.e. with the beginning of the Industrial Revolution).

    So IPCC Chapter 5 is weak. Let's see is we can find some more data out there that IPCC may have overlooked.

    A study starting with the statement: "ocean plankton have been ignored in most climate change models until now" suggests that higher carbon dioxide levels mean that ocean plankton will prosper and in doing so will soak up more and more of the carbon emissions absorbed from the atmosphere.  This biological "negative feedback" is not mentioned by IPCC.
    http://robertkyriakides.wordpress.com/2008/03/07/plankton ...

    Another study has shown that higher CO2 levels and temperatures in the upper ocean promote coral calcification, and boost coral-symbiant photosynthesis, again providing a biological "negative feedback" to pH decrease, also not mentioned by IPCC.

    This study points out that corals prosper at warmer temperatures (no real surprise, when one looks at their latitudinal distribution), so that warmer ocean temperatures will be beneficial.

    The study concludes: "In the Great Barrier Reef, growth rates of corals have been shown to be increasing over the last 100 years, at a time when water temperatures have risen. This is not surprising as the highest growth rates for corals are found in warmer waters."
    http://www.onlineopinion.com.au/view.asp?article=6134& ...

    The above are just two examples of important biogeochemical "negative feedbacks" (i.e. buffering or mitigating effects) not mentioned in chapter 5.

    So, in summary, chapter 5 does not provide compelling physical evidence for:
    ·    An overall "acidification" of the ocean
    ·    An anthropogenic cause

    And it overlooks some documented biogeochemical "negative feedbacks" that could completely change any projections drawn from the limited physical data provided.

    Buy hey, Andrew, it's a good read and one source of information among many others ("e pluribus unum").

  • Just the facts on warming

    So far no one has been able to refute the fact that the Hadley temperature record shows no warming trend since 1998.

    If anyone has any data that refute this, please bring it now.

    Otherwise admit that this is the case.

    Global warming showed major temperature increase during the 22-year period from 1976 to around 1998 (following a cooling trend during the 31-year period from around 1945 to 1976).  Now it has started to level off (or even cool down) in the 10-year period starting in 1998.

    Whether this trend will continue is anyone's guess.

    You can go back even further and you will see multidecadal swings from warming to cooling, with an underlying warming trend of around 1 degree C over the past 150 years.

    Those are the facts, folks.

    Everything else is conjecture and hype.

  • Andrew is not always wrong, just this time

    Hey Andrew,

    You wrote: "Max selectively quotes the Hansen article.  Why not quote the entire sentence in, Max?  Because it wouldn't make your point?"

    Sorry, Andrew.  Your argument is weak.  You said that there were no papers saying that warmer oceans would cause release of CO2 which would cause an increase in global warming.

    I showed you two examples that disproved your statement, one from Hansen.

    Now you waffle around that I did not quote everything that Hansen said.

    Face it, Andrew.  Hansen said that a "GHG feedback" could come from CO2 released from the oceans due to higher temperatures.  Right?

    He even said this could be a most effective GHG feedback.

    And you said earlier to BW that there were no scientific papers that stated this.

    So you were wrong, Andrew.

    Admit it.  It can happen to anyone.  Even you.  Don't take it so seriously.  You are not wrong all the time.  Just this time.

    Just to make sure readers (including "lurkers") understand what is going on here.

    The record over the past 10 years shows that global warming has stopped.

    The IPCC Chairman has acknowledged that there has been a "plateau" in global warming.

    So let's all accept this fact and be happy.

    Isn't that good news, folks?

  • Andrew is wrong, yet once again!

    Hi Andrew,

    Sorry to cut into your exchange with BW, but you are wrong when you say: "Thanks for your response.  It's now crystal clear that you completely made up the "theory" that a warming world would lead to degassing of CO2 from the ocean.   For the lurkers: there's only one legitimate scientific theory, and that's increasing CO2 leads to ocean acidification.  If you want to see the science behind it, you can read the IPCC reports.  See Chapter 5 of the WGI report. "

    Ummm... Maybe you should encourage your "lurkers" to read what James E. Hansen had to say:
    "Most effective GHG feedback is release of CO2 by ocean at higher temperature"
    http://www.columbia.edu/~jeh1/2008/TargetCO2_20080407.pdf ...

    Then read what J. Ahlbeck had to say about this subject:
    http://www.john-daly.com/oceanco2/oceanco2.htm

    It's out there, Andrew.  All you gotta do is look for it.

    Now I'll admit that you can probably tell your "lurkers" that Hansen's dire predictions of "positive feedback from ocean `outgassing' of CO2 at higher temperatures" may be wrong, but this theory is out there by an otherwise respected (if somewhat hysterical) climate scientist.

    The analysis by Ahlbeck may be less interesting for you and your "lurkers", but it's out there, too.

    So your statement that BW "completely made up the 'theory' that a warming world would lead to degassing of CO2 from the ocean" is not true.

    Hansen and others made it up and published it.

  • Still warming?

    The lead article passes out some sage advice:
    ""When you look at climate change you should not look at any particular year. You should look at trends over a pretty long period and the trend of temperature globally is still very much indicative of warming." You know, lest your friendly neighborhood skeptic needs reminding."

    Both the surface and satellite records show that there has been no warming in the past decade (1998-2008).
    http://vortex.nsstc.uah.edu/data/msu/t2lt/tltglhmam_5.2
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    To confirm this, all you have to do is download the monthly data from January 1998 to today into Excel and put in the linear trend line.

    You will see that it is flat.

    When the IPCC Chairman was recently asked about this, he said he would check if there were possibly natural factors that had caused this observed "plateau".

    The prior trend from 1976 to 1998 has been used by IPCC as the basis for claiming accelerated global warming caused by anthropogenic greenhouse gases.

    This record covers 22 years, or 2.2 times the time span of the most recent flat trend.

    On this basis IPCC projected temperature increase of 0.2 degrees C per decade for the first two decades of the 21st century.

    Is the most recent 10-year record a "trend"?  Is it a temporary "anomaly"?  Who knows?
    We will have to wait and see.

    But it does raise serious questions about the ability of the IPCC climate models to project future temperature increase.

    Now there are those that will "debunk" the statement that global warming appears to have slowed down by accusing me of introducing an "artifact" by choosing January 2008 as the start of the "past decade", since 1998 was the warmest year on record.

    So I did the same analysis with different starting points.

    If I plot the trend starting January 1999 I get a linear trend of +0.009 degrees C per decade (less than 5 percent of the +0.2 degrees C per decade as projected for the first two decades in the 21st century by IPCC in its 2007 SPM report). Looks pretty close to "flat" to me.

    Then I also checked the actual trend with later start dates:
    Starting in 2000, the warming trend is +0.004 degrees C per decade
    Starting in 2001, the cooling trend is -0.009 degrees C per decade
    Starting in 2002, the cooling trend is -0.018 degrees C per decade
    Starting in 2003, the cooling trend is -0.023 degrees C per decade

    It looks like the IPCC Chairman is correct when he refers to the recent flat trend as a "plateau" in global warming and the "debunkers" of the flat trend are "flat wrong", based on the facts.

  • Record shows global warming has reached a plateau

    The lead article raises questions about the statement that global warming has stopped, but unfortunately the "artifact" claim does not hold (1998 was an unusual record year, so cannot be used as the starting point).

    The statement was made that the claim of no warming since 1998: "has been thoroughly debunked every time it's popped up". A link to a statement by James E. Hansen is cited.

    I prefer to go to the actual source of the data rather than relying on sites like gristmill or individuals like Hansen to tell me a message they want to get across.

    So I downloaded the Hadley record:
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    I then plot the most recent record with different start dates:
    If I plot the last 10 years (starting January 1998, ending February 2008) I get a totally flat trend.

    If I plot the trend starting January 1999 I get a linear trend of 0.009 degrees C per decade.  Taken over the 9 years this is a linear increase of 0.008 degrees C per decade (not 0.2 degrees C per decade as projected for the first two decades in the 21st century by IPCC in its 2007 SPM report).

    Then I also checked the actual trend with later start dates:

    Starting in 2000, the warming trend is +0.004 degrees C per decade
    Starting in 2001, the cooling trend is -0.009 degrees C per decade
    Starting in 2002, the cooling trend is -0.018 degrees C per decade
    Starting in 2003, the cooling trend is -0.023 degrees C per decade

    It looks like the facts show that the IPCC Chairman is correct when he refers to the recent flat trend as a "plateau" in global warming and the "debunkers" of the flat trend are "flat wrong" (if you'll pardon the expression).

    Starting in 2003, the cooling trend is -0.023 degrees C per decade

  • The trend is flat, MNG

    Hi MNG,

    You took issue with my statement that global warming has leveled off since around 1998, by referring me to a gristmill site.

    You wrote: "The data on the graph illustrates the artifact of year selection.  If, instead of looking at 1998 and 2007, you compare the temperatures of 1999 and 2007, you see a temperature increase of almost 0.27 degrees.  But that temperature difference is no more significant than the lack of difference during 1998 and 2007.  It is the trend that matters, not comparisons between discrete years."

    Sounds good, MNG, but I prefer to go to the actual source of the data rather than relying on sites like gristmill to tell me a message they may want to get across.

    So I downloaded the Hadley record:
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    If I plot the last 10 years (starting January 1998, ending February 2008) I get a totally flat trend.

    If I plot the trend starting January 1999 I get a linear trend of 0.009 degrees C per decade.  Taken over the 9 years this is a linear increase of 0.008 degrees C, not 0.27 degrees C as grist has erroneously stated.

    You are absolutely correct; it is the trend that matters.  If you take the full decade you get a flat trend, if you start in 1999 you get an almost flat trend.

    This is also why the Chairman of IPCC acknowledges that there has been a "plateau" in global warming.

    This record covers 22 years, or 2.2 times the time span of the most recent flat trend.

    On this basis IPCC projected temperature increase of 0.2 degrees C per decade for the first two decades of the 21st century.

    Is the most recent 10-year record a "trend"?  Is it a temporary "anomaly"?  Who knows?
    We will have to wait and see.

    But it does raise serious questions about the ability of the IPCC climate models to project future temperature increase.

    What do you think, MNG?  Has "rampant" global warming really stopped?  Is the AGW bubble about to burst?

  • MNG is still worried - but does not need to be

    Hi MNG,

    You wrote:"The above-stated inability of this particular researcher to accurately determine the `average' ocean pH, and the accompanying conclusion that changes to the `average' pH can't be determined, seems to enhance, rather than reduce, the general risk-aversion urge that leads people to proceed with caution when faced with uncertainty."

    Not really, MNG.

    It just points out that all the "hype" about pH reduction in the ocean is just that: hype.  

    Other reearchers have been unable to come up with definitive 'average' numbers, while this researcher showed that there was no overall pH reduction in the ocean.

    Don't fret, MNG.  There is nothing to really worry about. "Not being able to determine a lowering in pH" does not equate to "maybe we should proceed with caution" (whatever that means), because there may be a pH problem, does it?

    The buffering capability of the ocean and all its contents is such that the current and future CO2 emissions from the paltry human fossil fuel consumption could not do much to decrease the ocean pH significantly.

    But if you enjoy worrying and fretting about imaginary future disasters, by all means, enjoy!

    I just do not believe that it makes much sense.

  • Don't worry about ocean pH, MNG

    Hi MNG,

    See in your discussion with Black Wallaby that you are apparently concerned about possible future lowering of ocean pH due to anthropogenic CO2 emissions.

    I've seen many "predictions" of future changes in ocean pH but very few actual measurements of what is really going on today to support these forecasts for the future.

    The site below provides some good information.
    http://www.seafriends.org.nz/issues/global/acid2.htm#how_ ...

    I have quoted the conclusion below:
    "How acidic are the oceans?
    As this map suggests, ocean pH measurements have been done all over the world and in the most unlikely places. The false colour scale on the right suggests a range from 7.9 to 8.2 (personally I have measured a wider range from 7.8 to 8.3). The lowest pH occurs in upwelling areas whereas highest pH occurs in the centres of ocean gyres.

    From this extensive mix it would be difficult to state what the 'average' pH is for the oceans, let alone whether the oceans have become more or less acidic.

    Note that upwelling areas are more acidic because high-CO2 bottom water surfaces, warms up and makes CO2 more readily available, a bonus for photosynthesis by marine plankton."

    The key conclusion here is "one cannot really say that the ocean has become more or less acidic".

    So there is probably much less to worry about than some alarmists would have us believe.

    Hope this bit of good news helps allay your concerns.

    Regards,

    Max

  • Some thoughts for MNG

    Hi MNG,

    Sometimes it's good to clear the mind from all the day-to-day hype and take the "satellite view" on what is going on.

    All of the fossil fuel we are burning today was originally atmospheric CO2.

    So in our little way, we are returning to the atmosphere very slowly what was there a long time ago.

    Of course, the whole cycle is much more complicated.  As atmospheric CO2 concentrations increase (either from human emissions or from natural degassing as oceans warm up ever so imperceptibly), the natural cycle (which is so much greater than our human input) takes over.

    This perspective sort of lets me see just how puny and insignificant we really are on this planet, despite our high intelligence and bloated egos.  Insects generate more CO2 than humans.

    There are some who have the arrogance of believing that they can "predict" where this is all leading us, and it will obviously be "bad" if not downright disastrous.  But do these self proclaimed "prophets" really know what they are talking about?  Should we really take them seriously and fear for the future of our planet?

    Should we take out an expensive "insurance policy" to attempt to stop this imagined threat "just in case"?

    I do not believe so.

    All throughout human history there have always been prophets of doom.

    Often they have tied their predictions to the wrath of an Almighty for the transgressions of man, using guilt and fear to sell their "repent now or die" message.

    One of the earliest written records of ancient Sumeria (later rewritten by the Jews), tells us of a climate disaster (the Great Flood) caused as a result of the sins of man.

    This latest scare is no different, MNG.

    And after this one has passed into oblivion, there will certainly be a new one.

    That's human nature.

    But I would not take all this stuff too seriously, MNG.  There is no impending disaster from human CO2 emissions.

    "Too much of a good thing" in the case of clean drinking water is about two lungs full, I would guess, while for CO2 it is apparently somewhere between 5,000 and 10,000 ppmv with prolonged exposure (or two lungs full at 100%, as you pointed out in the case of asphyxiation).

    Hi Robco,

    Let's carry your "fill the car with CO2 analogy" a step further: "Okay, Fill a plastic bag with CO2 from a tank (I know it doesn't come from the car's tailpipe; you just love the red-herrings, don't you?) and stick it over your head."

    With this brilliant statement you have shown me that CO2 is "pollution".

    Filling your car up with clean drinking water (with or without red herrings) while you are sitting inside would not be too smart, right?

  • Some temp. facts for Robco1

    Hi Robco1,

    Yesterday you wrote me: "Over the past decade global temp. has increased dramatically, in line with the worst projections from credible scientists."

    I sent you the links to the Hadley and UAH globally averaged surface and tropospheric land and sea temperature records, so you could check some actual data (not just "the worst projections from credible scientists").  

    Did you download the record for "the past decade" (i.e.the period 1998-2008)?

    Did you copy the data into Excel and establish the linear trend line over this period?

    Did you see that the trend line is flat?

    You should do this before you make claims about dramatic increases in global temp. over the past decade.

    Keeps you from shooting yourself in the foot with incorrect statements.

    Just a tip.

    Hi Pangolin,

    At the risk of "feeding a troll", I will respond to your post.

    Everything you have written about "dose response" makes sense.

    You also wrote: "Outside of a narrow band climate patterns change and flora and fauna can become isolated populations or go extinct."

    To which "narrow band" of climate are you referring?  Which evidence is the basis for determining this range?  Which flora and fauna have become isolated due to climate change caused by anthropogenic GHG emissions?  Which have become extinct due to climate change caused by anthropogenic GHG emissions?  Please list specific examples with evidence that the isolation/extinction was caused by climate change caused by anthropogenic GHG emissions.  Thanks for your response.

    My point, which you did not address related to a fallacy in Andrew Dessler's analogy,  i.e. the basic difference in the "robustness" of the cause and effect relationship between UV radiation and skin cancer as compared with human CO2 emissions and more frequent and intense tropical cyclones or extreme weather events.

    In one case we have the reality of countless case studies based on the past experience of actual patients; in the other case we have the greenhouse theory and the virtual reality of computer climate models plus "expert opinion rather than attribution studies" to project future climate changes.

    Would you like to address this point as well with some specific evidence that can refute my statement?

    Thanks in advance for your reply.

  • Cancer link is robust

    Hi MNG,

    Agree with you that not everyone who exposes him/herself to UV radiation will get cancer.  

    The case studies based on actual patients have shown, though, that incidence is much higher for melanoma among those individuals who had sunburn during childhood/adolescence; likewise, the incidence of nonmelanoma skin cancer is linked to the level and degree of exposure to ultraviolet radiation.  (Sort of like the studies linking smoking and lung cancer.)

    This is what I would call a pretty robust cause/effect relationship.

  • Sounds good, MNG, but...

    Sounds pretty good, MNG, until you consider that the "association between sun exposure and skin cancer" is extremely robust while the "association between greenhouse gases and climate change" (i.e. increased incidence of intense tropical storms and other severe weather events) is not very robust at all.  In fact, it is very weak or even non-existent.

    So staying away from excessive UV exposure to avoid the risk of skin cancer as an individual makes excellent sense, while attempting reduce the risk of hurricanes and other severe weather events by reducing global CO2 emissions does not.

  • Message to Andrew Dessler

    Hi Andrew,

    The analysis of your lead article in the very first comment by benp was very much to the point regarding the "poverty of climate change ethics" as exposed by the attempts to link the climate change debate with other, totally unrelated issues. An earlier example of this fallacy was the "holocaust denier" analogy.

    But I think another, more basic, fallacy in your analogy is the basic difference in the "robustness" of the cause and effect relationship between UV radiation and skin cancer as compared with human CO2 emissions and more frequent and intense tropical cyclones or extreme weather events.

    In one case we have the reality of countless case studies based on the past experience of actual patients; in the other case we have the greenhouse theory and the virtual reality of computer climate models plus "expert opinion rather than attribution studies" to project future climate changes.

    You made the statement that: "The association between sun exposure and skin cancer is every bit as robust as the association between greenhouse gases and climate change. And that means it's pretty damn robust."

    But therein lies your fallacy.  The "association between sun exposure and skin cancer" is extremely robust while the "association between greenhouse gases and climate change" (i.e. increased incidence of intense tropical storms and other severe weather events) is not very robust at all.  In fact, it is very weak or even non-existent.

    Do you have any counterargument to refute my statement?

  • Robco1 gets it wrong again


    Wrong again, Robco, when you say: "Just because it occurs naturally does not mean it can't be a pollutant. As you well know, CO2 is pollution when you have too much. Don't believe me? Fill your car with CO2 and sit inside with the windows shut. Which you must already be doing to come up with a series of factual errors."

    Sorry Robco, looks like the "red herring" is yours.  Here's a brief lesson in Chemistry 101:  when you sit in your car and fill it with exhaust gas it is NOT CO2 that kills you.  It is CO.  (That's carbon monoxide, not carbon dioxide).  Got the difference?

    CO2 could be dangerous to humans above 5,000 ppmv, but there is not enough fossil fuel on this planet to ever reach this level in the atmosphere.

    Over the past decade (1998-2008) CO2 has gone up steadily but global temp has not increased at all, as you claim.  Check the records:
    http://vortex.nsstc.uah.edu/data/msu/t2lt/tltglhmam_5.2
    http://hadobs.metoffice.com/hadcrut3/diagnostics/global/n ...

    Plot it for yourself and you will see that the linear trend is flat.

    The "worst projections from credible scientists" said it should increase by 0.2 degrees C per decade for the first two decades in the 21st century.  Looks like they were flat out wrong, Robco, doesn't it?

    You wrote: "The key words there are `honest' and `credible.' You folks should try to become familiar with them sometime."

    This statement is a bit fuzzy.  Tell me what you are trying to say here, Robco.  

    Were the incorrect projections of your "credible scientists" "honest" and "credible"?

  • You got it wrong, Robco1

    Sorry Robco, it appears you are missing the point.

    SO2 is pollution.  It does not exist naturally in the atmosphere to any significant extent.  It is a cause for respiratory problems in humans, for destruction of plant life at higher concentrations and is believed to be a principal cause for acid rain.

    CO2 is not pollution.  It is an essential trace component of the Earth's atmosphere; no CO2 = no life.

    There is no evidence that a reduction of CO2 emissions will have any significant impact on future intensity or frequency of tropical cyclones or future frequency of other extreme weather events.

    There is no compelling evidence that a slight warming trend (if it continues) will be more harmful than beneficial for mankind, for the environment and for the future of "our planet".

    Over the past 10 years CO2 concentrations have increased annually, but there has been no increase in the "globally average surface (or satellite) land and sea temperature anomaly.  Why is this?

    The IPCC chairman has indicated he would look into why there has been a plateau in temperatures, and we are all awaiting some answers.

    So that it the basic difference here.

    Got it now?

    Hey Robco1,

    Just so you know where I stand on "delaying progress", here is what I wrote on another Grist thread.

    I am certainly NOT in favor of being a "delayer" when it comes to:
    ·    Improving energy efficiency in power generation (i.e. revamping or replacing old inefficient plants with newer plants)
    ·    Reducing waste on all levels
    ·    Reducing real air and water pollution (not CO2 emissions)
    ·    Reducing dependency on imported oil coming from politically unstable regions
    ·    Improving fuel efficiency of automobiles
    ·    Developing new energy-efficient sources of automotive fuels
    ·    Developing and installing more cost-effective renewable power generation sources
    ·    Building more nuclear power plants, and ensuring these are safe, of course)
    ·    Developing new fast breeder technology
    ·    Developing nuclear fusion technology
    ·    Etc.
    But I am in favor of being a "delayer" when it comes to the implementation of draconian carbon taxes or cap and trade schemes, which will cost everyone a lot of money and will make some people, organizations, hedge funds or money shufflers rich, but will accomplish none of the above.

    Hope this clears it up for you.

    But this is all sort of off the topic of this thread, which has to do with an analogy of skin cancer with AGW.

  • Weakness in the analogy

    The analogy between skin cancer (caused by exposure of the skin to ultraviolet radiation) and global warming (caused by increase of atmospheric carbon dioxide) is, at first glance, compelling.

    The analogy is made, "the sunlightscam website talks about how there is an enormous conspiracy between dermatologists and sunscreen manufacturers to promote this scam. It's all about the money. That's just like the conspiracy between climate scientists and politicians to create the fake problem of climate change."

    Leaving aside the "conspiracy chatter", we see that there are some basic differences if we dig a bit deeper into the facts,.

    These relate to the "levels of evidence" (linking the cause with the effect).
    http://www.meb.uni-bonn.de/cancernet/304733.html

    The evidence linking the incidence of nonmelanoma skin cancer to the level and degree of exposure to ultraviolet radiation is provided by
    ·    Controlled trials
    ·    Case-control analytic studies
    ·    Opinion of experts based on clinical experience

    The evidence linking the incidence of cutaneous melanoma to the incidence of exposure to sunburns, especially in childhood and adolescence is provided by
    ·    Case-control analytic studies
    ·    Ecologic studies with a cancer incidence link
    ·    Opinion of experts based on clinical experience

    In other words, the evidence is in the form of observed effects directly linked to actual physical causes.  

    A description of one case-control study shows how a sample of subjects "were interviewed about their lifetime sun exposure, including exposure to the site of the squamous cell carcinoma (sites for controls were assigned randomly). Analysis was restricted to 132 cases and 1,031 controls born in Australia and with no ancestors from southern Europe. The total site-specific exposure was strongly related to risk of melanoma; the odds ratio increased to a maximum of 3.3 at 65,000 hr of exposure before falling slightly. Site-specific exposure during childhood and adolescence was more strongly associated with SCC than exposure during adulthood. The number of blistering sunburns to the site was positively associated with SCC. Use of sunscreens and hats showed inconsistent effects. Sun exposure, especially during childhood and adolescence, increases the risk of SCC."
    http://www.meb.uni-bonn.de/cgi-bin/mycite?ExtRef=ICDB/983 ...

    There have been many such studies, all showing an observed direct link between skin cancer and exposure to ultraviolet radiation.

    In the case of anthropogenic global warming we are missing this direct link.  

    The link is suggested by the greenhouse theory and computer generated climate model studies, which project future changes in globally averaged land and sea surface temperatures, based on projected future atmospheric concentrations of anthropogenic greenhouse gases. These are then linked to projections of a higher incidence of more intense tropical storms more severe weather events and accelerating sea level rise in the future.  These possible future developments are said to be "likely" or "more likely than not" to occur as a result of human influence based on "expert opinion rather than attribution studies".

    In effect we are comparing observed physical evidence with conjecture based on theory and the virtual reality of computer models.

    This is the key difference and, therefore, the key weakness in this analogy.

  • Here's some history for Andrew

    "Accentuate the positive, eliminate the negative."

    Hi Andrew,

    This was before your time, but James E. Hansen was only 2 years old when this 1943 hit by Johnny Mercer hit the charts.  

    He is now heading the NASA Goddard Institute for Space Studies (GISS).  As you know, these are the guys that put together temperature records and model studies for the future, under Hansen's leadership.

    But this song has obviously made a lasting impression on him over all these years.

    He is now "accentuating" the "positive feedbacks" in climate change and "eliminating" the "negative" ones.

    Kinda `splains this bizarre behavior, doesn't it?

    Yeah.  I read all the latest IPCC stuff (no "huff", though).

    Guess if their next reports come out in 2013, we'll know more by then about the current "temperature plateau" (as their Chairman calls it) and whether this was the start of a long term flattening or even downturn of the curve.  Maybe IPCC will even share some thoughts on what caused it.

  • Achilles Heel of science

    Josullivan58 is correct in saying that scientists should "follow a high standard of behavior" and therefore should not "be dishonest".

    The problem arises when science is mixed with politics and is being driven by an agenda that is fueled by large sums of money.

    It would be a wonderful world if all scientists really were able to "follow a high standard of behavior" and be totally honest all the time.  

    But money and politics drive this world, josullivan58, whether this is the "coal lobby", the "green activist" lobby or UN bureaucrats and politicians.

    This danger of being misused to achieve a political agenda is the real "Achilles heel" of science.

  • Taxes as solutions to problems

    GonzoDon raised some interesting questions.

    There have undoubtedly been periods in history where taxes were implemented to finance a specific solution or political course of action.

    Forgetting the classical example of the rise and fall of the Roman Empire (both of which came about to a great extent due to taxes), one can look at U.S. history.

    The first federal income tax was imposed in 1862 to finance the costs of the Civil War.  It was repealed in 1872.

    Shortly before WWI Congress reenacted a federal income tax, which was then increased to finance WWI.  This one never got repealed.

    During the Great Depression the top marginal tax rate was increased in an effort to "level" the wealth between rich and poor and to finance large public works projects to help reduce massive unemployment.

    And during WWII the rates were increased again, this time to finance the costs of the war.  Payroll withholding and quarterly tax payments were also implemented to accelerate tax revenue cash flow.  

    Since 1935, the Social Security "tax" is actually a federally mandated retirement savings plan or "social insurance program", covering the benefits for retirement, disability, survivorship, and death.

    In 1965 Medicare and Medicaid were added to provide medical insurance coverage for seniors and indigent patients, and in 1972 the coverage was extended to ceratin disabled persons under the age of 65.

    So yes, these "taxes" were all enacted to "solve a problem".

    The gasoline "taxes" go toward financing the roadways, so are actually more of a "user's fee" than a real tax.

    The proposed "carbon tax" would be a similar tax on all carbon-containing fossil fuels, but what would they, in fact, finance?  And even more important, what "problem" would these taxes solve?

    Cap and trade schemes are even less transparent.  These caps supposedly generate a market value for carbon.   It is clear who will pay for all of this (everyone).  Who will be the beneficiary is a bit less apparent.  These schemes will undoubtedly earn a lot of money for some individuals, companies, hedge funds and other money shufflers.   Platitudes such as "the atmosphere is owned by all humanity" are being used to justify these schemes as a part of an "equitable, ethical and politically effective climate policy".  The question must again be asked: what specific "problem" would these schemes solve?

    GonzoDon is correct in his statement.  The Civil War, WWI, the Great Depression,WWII, public health care for the elderly, the disabled and the indigent, building and maintaining the roadway network are all examples of real problems and issues that were "solved" by providing adequate financing through taxation.

    In the case of a climate policy including carbon taxes or cap and trade schemes to "solve" global warming it is not evident:
    ·    That global warming is indeed a real problem that needs to be "solved"
    ·    That the proposed political action (tax or cap and trade) will have any net beneficial effect

    To me that is the big difference.

  • Why is delaying a bad thing?

    So far I have not seen any compelling arguments against "delaying" action until we can truly see whether or not the current (1998-2008) flat or even cooling temperature trend is the beginning of a longer term trend.

    The "imminent disaster" and "tipping point" hysteria calls for immediate action. This alarmist position is based on the premise that "positive feedbacks" dominate the climate system.

    New scientific findings show that strong "negative feedbacks" from clouds tend to regulate the climate system instead. These have been overlooked by the many climate model studies that show alarming projections.

    These findings, plus the fact that temperatures have reached a plateau (or are even beginning to drop), would tell me, as a rational skeptic, that now is the time to first find out what is really going on before rushing to implement draconian measures that may not bring us any benefit at all, but will undoubtedly be very costly for everyone.

    That is why I believe being a "delayer" may not be such a bad idea, after all. Let's get all the facts before we rush into action.

    If anyone has any rational arguments against this position, I would be glad to hear them.

  • Message to LegumeSam

    Pardon the expression, LegumeSam, but you are (as your name implies) "full of beans".

    First, your claim that 10 years is too short to make a trend, I can only add that 22 years (1976 to 1998) is only 2.2 times that long, and this period is being used to sell the whole AGW story.

    Your statement "The energy production sector is damaging ecosystem integrity in order to make a buck" is totally contrived.

    The question is not "whether any technical upgrade would `throw the whole world into a major recession'", it is whether we need to implement carbon cap and trade schemes or taxes to achieve this.  I really do not think so.  And I do not think you have brought me any evidence that this is the case.

    We will have "technical upgrades" (because these make good economic sense as they always have in the past).

    Draconian carbon taxes or cap and trade schemes will neither reduce the world's "carbon footprint" nor resolve any "peak oil" problems.  I have never heard of a case where a heavy tax has solved any problem.  Have you?

    Switching to alternate energy sources (domestic clean coal, nuclear, renewable sources and others) as imported oil becomes too expensive or geopolitically risky makes a lot of sense.  But we do not need any carbon taxes or cap and trade schemes for this to happen.

    You wrote: "New energy technologies will, in themselves, do nothing to deal with the problem of abrupt climate change."  What problem?  What abrupt climate change?  Where is this and how do you document that it exists at all?

    You closed with, "If we want to be ecosystem stewards, we need to move away from an economy that makes stuff to make a buck, toward an economy that does otherwise."

    What do you mean by "otherwise"?  Does this mean "move toward an economy that does not make stuff to make a buck or to make stuff that does not make a buck"?

    What kind of an economy is that?

    Who pays for the wages and salaries of the people who are "making the stuff"?

    Taxes?

    Who is paying the taxes?

    Get real, LegumeSam.  You need an economy to support all these good ideas, not on government regulation and taxes.  Wake up to the real world out there.

  • Sicks and stones for josullivan58

    Hey Josullivan58,

    It's getting late here, but since you have responded to my post, thought I would help clear your memory before retiring.

    I had always assumed you were rather young, but in light of your apparent memory lapses, I may have been wrong, i.e. "I don't think I wrote those things. I have never even heard of the expression `sock puppet'".  So I thought I would refresh your memory.

    On 20 Mar you wrote in an eloquent treatise referring to me and Black Wallaby "Don't feed the trolls".  You also wrote "manacker and his sock puppet Black Wallaby".

    On 1 Mar on the gristmill "Hurricane" thread you wrote, again in referring to me that "trolls get paid by the comment".

    On 1 Feb on the "Climate change is real" site you opined, "it's amazing how arrogant manacker is".

    On 10 Feb, again on the "Hurricane" thread you pointed out that "manacker is firmly in the 38% of people not entitled to have an opinion"

    On 24 Jan on the "Inhofe skeptic of the day" thread you told the world that manacker is a "black knight" and that "manacker hates freedom".

    And finally on 27 Dec on Andrew Dessler's infamous and totally bogus "Inhofe 400" site you explained in referring to me that "contrarians" don't have facts on their side.

    It's OK, though jo.  Don't fret.  I'm not angry with you.

  • Are "delayers" really bad?

    Joseph Romm's critique of the Pielke et al paper misses a key point.

    Pielke's paper simply states the case that it may be not as easy to stabilize CO2 emissions as we may have been led to believe, and that the technological advances that will be required to achieve this stabilization may take longer to achieve than has been optimistically assumed.  

    For this he is lumped together with "Bush/Lomborg/Gingrich" as a "delayer", with the implication that delaying action is tantamount to courting disaster for our planet.

    The even more pertinent question should be raised: "why should we spend billions (or as many suggest hundreds of billions) of dollars and throw the whole world into a major recession in order to stabilize CO2 emissions (at an arbitrary level of 450 ppmv?) when we are not even certain that this will have any beneficial impact on the future of our planet?"

    Let's look at what is going on out there in the real world (not the virtual reality of climate models) and ask some basic questions.

    Is the global warming paradigm collapsing? (There has been no warming trend since 1998, despite steady increases in atmospheric CO2 concentrations).

    Are the hypotheses that "positive feedbacks" dominate, upon which the whole global warming scare is based, coming unraveled?  (Latest satellite findings confirm earlier theories that natural weather processes automatically regulate temperatures to prevent runaway warming.)

    Are some doomsayers becoming shriller and shriller in a "last ditch" attempt to keep the global warming hysteria alive? (Imminent computer-generated "tipping points" from which the planet will not be able to recover are being predicted, unless immediate actions are taken).

    How many more years of flat temperature trends (or even cooling) will it take until the multibillion-dollar global warming bubble bursts?

    Will this bring the dissolution of the IPCC and the collapse of the current boom in taxpayer-funded "climate research"?

    Will there be a new "anthropogenic disaster" prediction to replace global warming when it dies?

    Will we return to the "disastrous global cooling" scare of the 1970s, or will the new imminent man-made disaster be something other than climate-related?

    These are interesting questions of our times (2008), which cast in doubt the sinister consequences of being a "delayer".

  • Skeptics can be convinced by facts

    "Skeptics can be convinced by the facts."

    One the one hand we have "tipping point" predictions (to be reached when atmospheric CO2 levels reach 450 ppmv?).

    Arrhenius and Stefan-Boltzman tell us the increase from today's value to 450 ppmv will cause a whopping 0.16 degree C temperature increase.

    On the other hand we have the fact that over the most recent 10-year period since 1998 there has been no linear trend of warming in either the troposphere (UAH record) or at the surface (Hadley record).

    "The delayers, however, are very different and far more dangerous. They are trying to persuade people not to take action on a problem that has not yet become catastrophic, but which will certainly do so if we listen to them and delay acting much longer."

    The statement is correct that AGW has not (yet) become catastrophic.  The key fallacy is in the claim that it "will certainly do so".

  • Response to josullivan58

    Hey josullivan58,

    You asked for examples.

    Just going through some recent gristmill sites, you have called me (and what you call my "sock puppet, Black Wallaby") a "troll", written that I am "arrogant", that I "hate freedom", am a "black knight" or a "contrarian" and am "part of the 38% that are not entitled to have an opinion".

    These are all "ad hominem" arguments, which Wikipedia describes in its section covering "fallacies" as consisting "of replying to an argument or factual claim by attacking or appealing to a characteristic or belief of the person making the argument or claim, rather than by addressing the substance of the argument or producing evidence against the claim."

    Wikipedia goes on to say, "The process of proving or disproving the claim is thereby subverted, and the argumentum ad hominem works to change the subject.

    It is most commonly used to refer specifically to the ad hominem abusive, or argumentum ad personam, which consists of criticizing or personally attacking an argument's proponent in an attempt to discredit that argument. It is also used when an opponent is unable to find fault with an argument, yet for various reasons, the opponent disagrees with it. Many times, an opponent's use of an ad hominem attack is an indication that the opponent realizes that the argument itself is correct and cannot be refuted."

    Maybe you would like to point out where you feel that I have been guilty of the same on occasion.

  • Message for JCross

    Cherry picking versus making a mistake (or "screwing up").

    Hi John,

    Our Antarctica exchange is closed (partly thanks to the intervention of MNG).

    But I did want to clarify one point that seems to have caused you to react negatively.

    I started off discussing cherry picking in a more neutral sense than is apparently being assigned to it in the rather pointed on-going scientific debate surrounding AGW.

    During the middle of our latest exchange on Antarctica, Josullivan58 provided a definition of "cherry picking" from Wikipedia that was a bit more specific than the one I cited from Webster (which essentially defined it as simply "selecting the best"):

    "Cherry picking is used metaphorically to indicate the act of pointing at individual cases or data that seem to confirm a particular position, while ignoring a significant portion of related cases or data that may contradict that position."

    If, as this definition suggests, "cherry picking" implies that the selection of some data and the omission of other data have been done intentionally or even maliciously in order to deceive the reader, then (although this might appear to a neutral observer to be the case) it would be difficult to prove that this is what IPCC did when they ignored (or rejected or refused to accept as correct) the conclusions of the Davis and Wingham reports in making their contradicting claim of net mass loss in the AIS over the period 1993-2003.

    Since I cannot prove that a malicious intent to deceive was actually there on the part of IPCC, I agreed (after having seen Josullivan58's Wikipedia definition) that IPCC could just have made a mistake in ignoring the data from these reports (or it could just have been a "monumental screw up").

    The next time I use the expression "cherry pick", I will make sure that it includes the implication of malicious intent to deceive; if this malicious intent is not apparent, then I will use some other term.

    We can both stick to this rule, if you agree.

    Regards,

    Max

  • JCross' last obfuscation

    Hi John,

    You just wrote: "Max:  I note that your only reply to my points was to continue to misquote the IPCC report.  
    And I note that you have completely ignored the whole "honest mistake" equal "cherry picked".  That still requires some explanation.  I look forward to more conversations on this in the future."

    Sorry, John, that is not how debating an issue works.

    Please refer to my post of 31 March, 5:55PM for a summary.

    I presented an argument (IPCC ignored reports when making its claim).  I backed this argument with three premises, which I proved with backup references.

    From this I drew the conclusion that my argument was well founded.

    In an attempt to refute this, you countered with four premises.

    Two of these were irrelevant to the discussion (other similar reports included, review period still open), which I pointed out to you.

    The other two were incorrect (deadline missed, range of error included), as I pointed out to you in detail.

    Your gambit has been to obfuscate by bringing in new waffles and premises (moving goalposts, slightly pregnant, misquoting IPCC, relevance of cherry pick vs. mistake), in order to drag this discussion on ad nauseum rather than accepting that you have been unable to refute my original argument or premises.

    In addition, Black Wallaby has shown you in excruciating detail how and why IPCC selectively picked "IPCC message friendly" spot studies (showing mass loss) while, at the same time, rejecting or ignoring more relevant but "IPCC message unfriendly" studies (showing mass gain over the entire 11-year period).

    John, I cannot force you to step up and act like a man by admitting you lost this one.

    But I also do not intend to play your "obfuscation ad nauseum" game.  By the way, this is listed as one of the fallacies used in debating an issue.

    Sorry, game over.  You lost.

    Wingham/Davis showed "mass gain".

    Therefore, IPCC ignored (or rejected or refused to accept as correct) Wingham/Davis.

    Hi Josullivan,

    In going through your link I identified a few "fallacies" sometimes used by IPCC supporters in debating with AGW skeptics:

    Ad hominem (attacking the person instead of the argument)
    Appeal to motive (calling into question the motives of the opponent, i.e. "stooge for big oil")
    Appeal to ridicule (make fun of opponent, i.e. "troll, flat-earther, denier" or his/her argument)
    Bare assertion (AGW is true because IPCC, i.e. 2,500 "scientists", say it is true)
    Irrelevant conclusion (argument does not address the issue in question)

    Do you ever use any of these?  

    Think about it.

  • Identifying JCross' fallacies

    Hi John,

    Since you apparently like the more formal approach of identifying "fallacies", let's play your game.

    My "argument" is that IPCC ignored (or rejected or refused to accept as correct) the conclusions of one or more published reports, which directly contradicted its claim.

    The first "premise" is that IPCC made a claim of net mass loss of the Antarctic Ice Sheet equivalent to a sea level rise of 0.21 mm/year over the time period 1993-2003. (Proof of this "premise" is the 2007 SPM report.)

    The second "premise" is that Davis et al made continuous measurements of the AIS over the entire time frame of the IPCC claim, and that they concluded that these measurements showed a net mass gain of the AIS over this period. (Proof of this "premise" is the written Davis et al report.)

    A third "premise" is that Wingham used these same continuous measurements of the AIS over the entire time frame of the IPCC claim and added calculated estimates for marginal regions that could not be measured accurately; Wingham also concluded that there was a net mass gain of the AIS over this period. (Proof of this "premise" is the written Wingham et al report.)

    The "conclusion" is that in making its claim of net mass loss of the Antarctic Ice Sheet equivalent to a sea level rise of 0.21 mm/year over the time period 1993-2003, IPCC ignored (or rejected or refused to accept as correct) the conclusions of one or more published reports (Davis/Wingham), which both directly contradicted its claim. (Proof is provided by the three premises, which show that the claim by IPCC is incompatible with the conclusions of the reports.)

    You countered with a first premise that Wingham was published after the initial deadline for reports to be included and was not included for this reason.

    Since there were several other reports on this subject that were published after the initial deadline, yet were considered by IPCC, it is apparent that IPCC did not consider its initial deadline to be an "absolute" deadline, beyond which no reports could be considered, therefore, in fact, it was not a deadline at all.  This is the fallacy of your first premise.

    Your second premise is that Wingham was published before the close of the review period for Expert Reviewers.  This argument has no direct relevance, and in no way refutes the conclusion or any of the premises I listed.

    Your third premise is that the IPCC has published work in the past that was very similar to Wingham.  This argument also has no direct relevance, and in no way refutes the conclusion or any of the premises I listed.

    Your fourth premise is that while IPCC made a claim that was in direct contradiction with the conclusions of the two reports (Davis/Wingham), i.e. "mass loss" instead of "mass gain", the fact that IPCC worded its claim in such a way to include a "range of error" that could be construed to include the "range of error" of the two reports shows that IPCC did not ignore (or reject or refuse to accept as correct) the conclusions of the Davis/Wingham reports.

    This premise is weak for three reasons:
    ·    The claim made is a claim of a "net mass loss", regardless of the margin of error
    ·    The reports whose conclusions were ignored (or rejected or refused to be accepted as correct) concluded that there was a "net mass gain"
    ·    The margin of error of the IPCC claim does not include the entire margin of error of the Davis/Wingham reports, in other words it ignores (or rejects or refuses to accept as correct) both the conclusions and the margin of error as concluded by these reports.

    In other words, it is clear that none of your premises has been able to refute any the premises I made or the conclusion of my argument that in making its claim of net mass loss of the Antarctic Ice Sheet equivalent to a sea level rise of 0.21 mm/year over the time period 1993-2003, IPCC ignored (or rejected or refused to accept as correct) the conclusions of one or more published reports (Davis/Wingham), which both directly contradicted its claim.

    The fallacy here in your "argument" is that the premises you have given for your conclusion do not provide the needed degree of support required to refute my stated premises and conclusion. As shown above, two are totally irrelevant and the other two are unsound due to errors in reasoning.

    Hope this clears it up for you.

    Max

  • John's "killer argument"

    Hi John,

    Let's look at your "killer" argument:

    "the range of values published by the IPCC includes the number that they are supposed to be ignoring"

    Davis reports a range of -5 to +85Gt/year
    This is based on millions of ESA satellite altimetry data points taken continuously over the entire time frame of the study.
    (Wingham adds in calculated estimates for marginal areas, using the same data.)  
    Both reports show a significant net mass gain over the entire period.

    IPCC reports a range of sea level change of -56 to +14 mm/year which equals
    a range of -194 to +50Gt/year (i.e. a net loss of -77±127 Gt/year)
    This is based on (who knows?) a cobbled together record, including a PORTION of Davis' range, none of Wingham's input,and a bunch of spot studies, which all together cover at best 13 months of the entire 11-year time frame, all cobbled together to (voila!) show a net mass loss rather than a net mass gain.

    So much for your "killer" argument.

    1. It does not include all of Davis' range.

    2. It is a "cobbled together" range based on adding up, averaging and adjusting "apples" with other fruit (including some "cherries?"), i.e. it is meaningless.

    Give up, John, your "killer" argument is a "dead duck" (or maybe, more appropriately, a "dead penguin").

  • JCross talks goal posts

    Hi John

    You wrote:  "Nice movement of the goal posts.  The argument was framed as the IPCC cherry picked because they did not cite Wingham."

    If you go back to read what I wrote, you can read: "As I told you, I am not saying that this proves that IPCC intentionally "cherry picked" reports that agreed with their desired message, although it might appear that way to the unbiased observer.  It could well have been that they just made an honest mistake when they ignored the Wingham report."

    I also told you that I frankly did not care whether IPCC intentionally "cherry picked" to prove their point, made an honest mistake (these guys are just human beings, John), or made a "monumental screw up" (to err is human).

    Just to refresh your memory, I wrote that IPCC ignored (or rejected or refused to accept as correct) the conclusions of both the Wingham and Davis reports, which both showed a net gain of the AIS over the entire time period 1993-2003, when they made their claim of net loss of the AIS over the exact same time period.  If one accepts Wingham/Davis as correct, one cannot, by definition, make a directly contradicting claim.

    I also pointed out to you that these two reports are the only two that covered the entire time period of the IPCC claim.  Other reports do not provide compelling information concerning the mass balance of the AIS over the entire time period covered by both Davis and Wingham, since they only cover small portions of the overall time frame.

    I also pointed out to you that your "December 2005 deadline" argument for Wingham is weak as a rationalization why this most important and relevant report was not included, since several less relevant reports that came out after this initial deadline were considered by IPCC.

    You have not been able to refute my statements, so any silly arguments about "moving goalposts" simply do not wash.

    Refute my statements above, if you think you can.  Otherwise, admit that you cannot.

  • A question for MNG

    Sorry to bother you again, MNG

    Does this causal context [ x causes y, thus if y, then x ] also work in the negative sense (assuming we are not talking about an illogical relationship)?

    An example:

    X = Globally averaged sea levels are rising at an accelerating rate
    Y = Low lying islands (Maldives) become inundated

    If globally averaged sea levels are rising at an accelerating rate
    Then
    Low lying islands (Maldives) become inundated

    Low lying islands (Maldives) are NOT becoming inundated
    Therefore
    Globally averaged sea levels are NOT rising at an accelerating rate

    Is this one logical?

  • Philosophy for MNG

    Hey MNG,

    This is fun!  Never had time to do too much abstract philosophizing, so thanks for the input: ."A causal context [ x causes y, thus if y, then x ] which is only logically correct if x is the only possible cause for y, and that depends on the specific case in question, as shown in the illogical relationship found in the previously posted example of Bill Gates and Fort Knox."

    Is this sort of like:
    X = human CO2 emissions
    Y = increased globally averaged land and sea surface temperature

    If human CO2 emissions increase
    Then globally averaged land and sea surface temperature will rise

    Globally averaged land and sea surface temperature is rising
    Therefore
    Human CO2 emissions are increasing

    Or is this a specific case where X is not the only possible cause for Y?

    Or is it simply an illogical relationship?

    Thanks for input.

    Regards,

    Max

  • Bill Gates is rich

    Thanks for your input, MosterNice Guy.

    How about this one?

    If Bill Gates is rich, then he has a lot of money.

    Bill Gates has a lot of money.
    Therefore, Bill Gates is rich.

    Does this one work better for you?

  • Forget Wingham, John

    Forget Wingham, John, and move on to something else, where you may have a chance of making a more valid argument.

    You have lost this part of our discussion, because you could not demonstrate that IPCC did not cherry pick when it ignored the only continuous set of data that refuted its claim of AIS mass loss over the period 1993-2003.

    Your arguments were feeble and, frankly, contrived.

    Both BW and I have provided ample evidence of this.

    So do yourself a favor and move on to another argument where you may fare better than you did on this one.

  • Some circular A-B logic for JCross

    Hey John,

    Still trying to cut through your "logic" double talk.

    The argument "if A then B" is logical, then "B therefore A" is not logically valid.

    Let's say A: If (A) it looks like a duck, it quacks like a duck, it walks like a duck, it swims like a duck, then (B) it is a duck.

    Now let's go to B: It (B) is a duck, therefore (A) it looks like a duck, it quacks like a duck, it walks like a duck, it swims like a duck.

    Sounds logically valid to me John.  Do you have any problems with this?  If so, what?

    Regards,

    Max

  • "A then B logic" for JCross

    Hi John,

    Sorry for cutting in to your dialogue with Black Wallaby, but since you mentioned my name...

    Your argument "if A then B" is logical, then "B therefore A" is not logically valid is a bit circular for me, but I am not going to get into this discussion

    You agree that my "premise" is logical and, you are right, I cannot prove that it is true.

    Nor can you prove that it is not true.

    You also cannot prove that it is not logical (in fact, you say it is).  As far as I can see, there lies the "fatal flaw" in your argument.

    But let's examine the reasoning.

    IPCC was set up (by the UN) to examine anthropogenic impact on climate (it's their "charter")

    No "anthropogenic impact on climate" = no need for IPCC.

    The law of self-preservation of bureaucratic committees is well documented in many treatises.  After all, trips to Bali, "swaning around" the world and staying in nice resort hotels at taxpayer expense is nice work (if you can get it).

    Now let's assume that the UN would like bureaucrats and politicians (including themselves) to be able to shuffle around hundreds of billions of dollars from carbon cap and trade schemes, taxes or whatever.

    Is this a logical assumption?  Do politicians and bureaucrats enjoy the power of being able to shuffle around large sums of public money?  Or do they abhor the mere thought of doing so?  Or are they totally indifferent?  What does the historical record show?  I think we know.

    So, if this assumption is correct, what do the UN politicians and leadership want the IPCC to conclude and report to the world regarding anthropogenic impact on climate:
    1.    That there is no impact
    2.    That there is an impact but it is beneficial on average
    3.    That there is an impact which could be negative, but is likely to be very minor
    4.    That there is an impact which is likely to be negative and could be alarming but there is absolutely nothing we can do about it
    5.    That there is an impact which is likely to be negative and could be alarming unless the "money shuffling" actions are implemented

    I think we can conclude that the logical choice is #5, (even if we cannot "prove" that this is the case).

    So we now have the UN "management" as well as its IPCC committee with an "agenda" to show the world that the anthropogenic impact on climate (from GHG) is likely to be negative and could be alarming unless mitigating steps are taken.

    Of course there are other individuals and organizations (politicians, the media, activist groups, etc.) that might also see a personal or financial benefit, but let's ignore these for now.

    So far we are talkin
