The American Geophysical Union, a scientific organization with over 50,000 members, mostly earth scientists, just released a position statement on climate change.
It is a strong endorsement of the mainstream view of climate science, as articulated by the IPCC reports: the Earth is warming, humans are to blame for most of the recent warming, and future warming may be disastrous.
While this is a strong statement by itself, its true strength comes when you consider that this statement is just one of a spate of similar statements by other expert organizations: the American Meteorological Association, the American Association for the Advancement of Science, the U.S. National Academy of Sciences (PDF), as well as several others. Even the American Association of Petroleum Geologists, while not exactly embracing the connection between carbon dioxide and climate, cannot bring themselves to contradict it.
Then, of course, we have the "Inhofe 400." Whom should we believe? Jim Inhofe or virtually all of the world's experts? That's a tough one ...

Piles of coal, battling windmills, and political leaders descend on college campuses.
In Springfield, Mo., college students are about to see quite vividly how much energy they consume. Piles of coal will be on display in proportion to what's needed each day to power their dorms, computers, and dining halls.
At Radford University in Virginia, students may stumble upon a mock fight between a windmill and a smokestack (costumes courtesy of the campus Green Team).
At the University of Vermont in Burlington, audience members will be encouraged to bike or walk to a one-woman show in which the fictional first lady calls for a boycott against sex until the nation starts a serious dialogue about climate change.
The creative tactics are designed to draw students into a series of events this coming week known as Focus the Nation: Global Warming Solutions for America. Organizers bill the culminating day, Jan. 31, as the largest teach-in in the nation's history, drawing parallels to the civil rights and antiwar movements of the 1960s and '70s. More than 1,500 institutions, most of them colleges and universities, will host classes, documentaries, performances, energy-saving competitions, and discussions with political leaders.
Eban Goodstein, the man behind the mission, speaks about it urgently: "What our kids have to do is truly heroic," he says. "If they're going to stabilize the climate for their children, they have to rewire the entire planet with clean-energy technology."
Rewire the entire planet foreign policy, yes you could certainly say that. How about that.

The AGU has believed that climate change is real for many years. The latest statement, to which Andrew refers, is actually a reaffirmation and update of an earlier statement from December 2003.
http://www.agu.org/sci_soc/policy/positions/climate_chang ...
To quote the latest update: "An additional global mean warming of 1°C above the last decade--is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and--if sustained over centuries--melting much of the Greenland ice sheet with ensuing rise in sea level of several meters."
Posing problems in planning for and adapting to? Yes, if warming 1°C above present.
Disruptive? Yes, if warming exceeds 2°C.
Several meter sea level rise? Yes, if sustained over centuries
Disastrous? Cannot find this word.
Tipping point? Cannot find these words.
Sounds like a level headed assessment by a group of scientists and engineers that believe "the human footprint on Earth is apparent".
BTW, the original AGU statement was drafted by Marvin Geller, John Christy and Ellen Druffel.
As Andrew knows, one of the three authors is also on Inhofe's list, and is quoted in this report as having said, ""I don't see a catastrophe developing from our emissions into the air of what should be correctly identified as `plant food,'"

You asked of Alan Siddons:
"Where did Dr Dessler state that climate is static? Could you provide a quote?"
In context, whether the wise doctor did, or is alleged to have said that, is quite irrelevant. The fact is that Mann et al produced a lovely graph that cancelled the MWP and the LIA, and made the millennial climate look flat (almost static) until the recent warming. Thus the IPCC seized this as Manna in the 3AR, to show falsely that the current warming is unprecedented. Since Andrew and all you faithful regard the IPCC to be the gold standard of scientific truth, Alan's comment is appropriate. Just take it in context....go-on try hard!

In April 2007 James Hansen, director of NASA's Goddard Institute for Space Studies in New York, presented to the US House of Representatives a study showing that greenhouse gases emitted by human activities have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.
http://www.columbia.edu/~jeh1/testimony_26april2007.pdf
He predicted that a global temperature increase of 1 degree Celsius above today's level, which he equated to an increase of atmospheric CO2 from currently around 380 to 450 ppmv, would represent a dangerous "tipping point", from which the planet could likely not recover. In moving beyond his area of expertise, which has to do with temperature impact of greenhouse gases and development and application of global numerical models for the purpose of understanding current climate trends and projecting humans' potential impacts on climate, he predicted that there would be extinctions of many animal species. Sea levels would rise dramatically as major ice sheets broke up suddenly, presenting a major calamity for humanity itself. Among his proposed solutions: a "carbon tax".
In a more level-headed commentary, John R. Christy, director of the Earth Science System Center at the University of Alabama in Huntsville, has said it is possible increased warming will be offset by other factors, such as increased cloudiness that would reflect more sunlight. "Whatever happens, we will adapt to it," Christy said. Christy is also quoted as having said, ""I don't see a catastrophe developing from our emissions into the air of what should be correctly identified as `plant food,'"
This tipping point debate has stirred controversy within the administration; Hansen has claimed that senior political appointees are trying to block him from sharing his views publicly.
But judging from the many media reports that are quoting Hansen's dire predictions and his own prolific publications and blogs on his "tipping point" theory, it appears he is not being "muzzled" at all. In fact, the volume of rhetoric coming out of Hansen exceeds the volume from Christy by about 20 to 1. So much for being "muzzled".
In commenting on Hansen's increasingly shrill forecasts, many critics have said that these are in direct contradiction with the vast majority of the scientific reports cited in the IPCC report, and that the rhetoric in the global warming debate is being ratcheted up until it, itself, is dangerously close to reaching a tipping point, where disaster predictions become so exaggerated and bizarre that people begin to see that they are no longer credible.
A good analogy to this tipping point can be seen in a dump truck of manure. As the truck starts to tilt the bed, the manure at first does not move. It some point the critical "tipping point" is reached when the whole load of manure comes rushing out of the truck.
It looks like this is what is happening in the global warming debate today. We are being inundated not by the predicted high sea levels (which have been imperceptible so far) but by the manure from Hansen and the media that has reached the "tipping point".

You also describe such people in various insulting ways, and seem to get quite emotional when it is indicated to you that you have been wrong on some scientific issues that you have previously been emphatic about. Apparently too, you like teasing the trolls. I refer to various threads where you have issued forth.
A simple case in point was when you insisted repeatedly that IPCC 2007 had a cut-off for inputs in 2005. When Manacker showed you that there are a host of papers from 2006 in the said report, no matter, you are right and he is wrong. The cut-off was in 2005, despite the evidence PROVING that to be wrong.
Thus you posted a falsehood intending to provoke a response. According to one cyber-dictionary, this defines YOU as a TROLL. Should we tease you? no, you are probably adequately "confused" already. Black Wallaby

Hi Greyfalcon,
Andrew Dessler has made a convincing argument in his lead article that climate change is real without offering any practical solutions.
I realize that Bjorn Lomborg has been the bane of the AGW orthodoxy since he wrote his book "The Skeptical Environmentalist", which made the case that there are more pressing problems facing the world today than global warming. This book unleashed howls of outrage from "mainstream" scientific journals and journalists, some of which accused him of "scientific dishonesty".
His recent follow-up book, "Cool It", did not do much to endear him to those that support drastic policy measures such as taxes for stopping global warming.
Lomborg is not a "climate change denier" as some may have labelled him. He has been quoted as saying: "We should take climate change seriously. It is a big problem. It's only one of the big problems that we'll face throughout the 21st century, but it is a big problem."
While one can agree or disagree with Lomborg's analysis on priorities, there is no doubt that he is no dummy and has done some serious thinking about the many problems of today.
A few weeks before the recent Bali climate conference Lomborg wrote an op-ed on the failure of CO2 targets to bring desired results. His article proposed an alternate solution.
http://www.washingtonpost.com/wp-dyn/content/article/2007 ...
His premise is that the focus on rapid reductions in CO2 emissions has not succeeded in the past and is unlikely to do so in the future. The 1992 Rio commitments to reduce emissions by 2000 were overshot by 12%. The 1997 Kyoto commitments to reduce emissions by even more by 2010 are likely to be missed by an even larger margin of 25%. His analysis: "Making ever stronger promises on top of ever more failed promises is hardly the right way forward."
Lomborg proposes a revolutionary approach to solving the problem by getting binding commitments from all countries to invest a small percentage of GDP on research and development of non-carbon-emitting energy technologies.
In this plan the richer countries would pay the larger share and each country would be free to pursue its own direction in moving away from fossil fuels, be that energy conservation, renewable sources, nuclear energy, fusion, or other solutions.
Lomborg estimates that the cost today to cut one ton of CO2 is around $20, and this cost is too high for major CO2 emitting nations, such as China and India, to consider as they are placing their priorities on rapidly growing their per capita GDP through industrialization.
Lomborg postulates that this proposal would therefore have the added benefit that it would not automatically allow certain nations, like China and India, to escape from global commitments to curtail emissions, but would include all nations. This has been a major stumbling block for getting the agreement from the USA.
He estimates that an investment of just 15% of what the currently proposed carbon taxes and cap and trade schemes will cost will increase by more than ten-fold the worldwide funding for research directed at moving away from fossil fuels and CO2 emissions. He equates this with an investment equal to 0.5% of GDP.
This would reduce the effective "cost" of removing a ton of CO2 from $20 to $2, thereby making it affordable not only for the rich nations of the world, but for everyone.
This sounds like a good return on investment.
His strongest argument is that this proposal would be provide a more cost effective way to reduce CO2 emissions than Kyoto and that it would be politically easier to approve and implement.
Any comments on the logic of Lomborg's proposal? (Please address the proposal rather than making "ad hominem" attacks to discredit the individual.)

Max

Quoting 'facts and figures' which can't be independently verified since most people don't have geology, meteorology, biology, et al in their curricula, requires a leap of faith which shouldn't be expected by glib protesters to convert adherents. Pictures are still worth a thousand words.
Sure, CO2 is a normal, natural and necessary part of the atmosphere, allowing plant life to breathe and exhale the Oxygen we use as animals. H2O is also normal, natural and necessary, but I remind all of you that you can drown in the middle of the vast Pacific Ocean or in an inch of water in your own back yard.

I don't think it would be effective.
_
Even if they could collect the money. Coal Sequestration, BioFuels, Hydrogen, and Nuclear would likely eat up all of it if it was done that way. (i.e. A big pile of money, without much to show for it)
There's no real impetus on actually creating emissions reductions. And as MIT has pointed out, technology without a regulatory framework could even make things worse.
http://www.greencarcongress.com/2007/11/mit-study-rate-.h ...
Additionally, it doesn't really put any prohibition on things which will make our siutation even worse. Like Coal-to-Liquids, or Clear Cutting Rainforrest.
Frankly it sounds effectively the same as what all right wing pundits say:
"Technology is the answer, but Regulation is evil!"
Effectively what it would end up being is that government would determine the tax (And collect too little)
And government would figure out how to spend it all (Without making any real results)
_
By comparison, Cap-auction-and-trade
Technologies would be given preference based on their Reductions/Cost performance
There actually would be a prohibition against dirty technologies. (Especially if tariffs equivalent to the domestic market are involved with countries that are in noncompliance)
Scientists figures out the emissions reduction targets
The Market figures out all the pricing involved, and how to get there
Very little government involvement except for collecting money, and oversight

Thanks for your fast response.
I see you favor the approach of "regulation to curtail emissions" rather than "incentive to develop new technologies" (i.e. the "stick" rather than the "carrot").
Which approach would be more effective? One is based on "positive" approach of providing incentives to encourage people to do the right thing; the other on the "negative" approach of policing people to discourage them from doing the wrong thing.
Let's go through your points.
"Even if they could collect the money. Coal Sequestration, BioFuels, Hydrogen, and Nuclear would likely eat up all of it if it was done that way. (i.e. A big pile of money, without much to show for it)"
I think the types of projects covered could be pre-determined, keeping out the "red herrings" but allowing each country to pick those areas within this pre-determined list, which make most sense for their economies.
Lomborg was talking about R+D for developing new technologies, so simply investing in existing nuclear technology could be excluded. While it does not generate any CO2, current nuclear technology is limited by reserves of uranium, which are estimated to be 35 million tons. If the world doubles the amount of nuclear generation by 2025, this would mean a 3.5% per year growth. At that growth rate, the world would use up the reserves shortly after 2100, so this is not the long-term solution.
This means we would need new technologies, such as fast-breeder reactors or totally new fusion technology. Developing these new technologies could be included.
Wind/solar/waste currently represent just under 1% of total power generation worldwide. With better R+D funding these could economically represent maybe up to 15% of the total in 25 years. This could also be included.
Geothermal energy is currently limited by deep drilling technology and other practical problems. It also represents just under 1% of total power generation today. This could possibly be increased several-fold if the technical problems could be solved with R+D funding.
Conventional hydroelectric power is limited in growth, but the use of tides to generate power could be an option that could require some prior R+D to develop optimum solutions.
Brazil does a very good job with sugar cane ethanol as a motor fuel. Currently corn ethanol in the USA is very inefficient (and may never become economically viable). Biomass could be another story, provided the R+D effort is made to develop this alternate.
I agree with you that hydrogen as a motor fuel is probably not a good prospect, since there are too many real safety problems with hydrogen and the overall efficiency of converting electrical energy to a motor fuel is too low. Fuel cells sound nice, but they will not solve the safety problem.
Whether or not net reforestation projects get funding could be considered, although this question could be handled in some other way to encourage reforestation and discourage deforestation.
To your point: "Frankly it sounds effectively the same as what all right wing pundits say:
"Technology is the answer, but Regulation is evil!"
I don't think you can argue with the fact that technology is the answer.
This has nothing to do with "right wing" or "left wing"; it is just common sense. Whether regulation is "evil" or not is a moot point; it just isn't the answer, since it will not solve any of the problems we face.
When you say: "Very little government involvement except for collecting money, and oversight", you must be kidding. How many folks are currently working at the US IRS or the German "Finanzamt" "collecting money and providing oversight", but not providing any added value to the economy (and this in countries, where corruption is dealt with fairly harshly)? This is the most inefficient way to channel money into real technical solutions for the problems we face. And if the "oversight" is provided by the UN, it will become even more inefficient, as we have seen from past experience when UN bureaucrats and politicians are involved in shuffling large sums of money and a portion ends up in personal offshore bank accounts. A bad solution.
"Scientists figure out the emissions reduction targets." This is a real loose cannon. Which "scientists" and on what basis? This puts scientists in the position of dictating policy - a very poor place for scientists. Would you agree with John Christy or Richard Lindzen being the "scientists" that make this call? Would I agree that it is James Hansen or Michael Mann? Forget that one, Greyfalcon. Scientists are not elected by the public and, as such, have no accountability to the public. Keep them in their laboratories, where they belong, not dictating policy. A really bad solution.
"The market figures out all the pricing involved and how to get there." What market? Last May the International Herald Tribune reported that the global market for greenhouse-gas emission permits more than doubled to $30 billion in 2006, as hedge funds and other new entrants tripled the European trading volumes (still in their infancy). These hedge funds as well as the companies such as the one set up by Al Gore are going to make big bucks on this whole money-shuffling exercise, without reducing one gram of CO2 emission. This would end up being pure "friction loss".
You have not been able to demonstrate to me that the "regulatory stick" (as espoused by IPCC and Al Gore) will provide the world a better long-term solution to this problem than the "technological carrot" (as proposed by Lomborg).
But I welcome your thoughts on my comments.

Max

Another Uranium source for Forsmark is the Rossing Mine in Namibia. A description of the operations of the mine is available here. The Rossing mine produced 3037 tonnes of Uranium in 2004, which is sufficient for 15 GigaWatt-years of electricity with current reactors. The energy used to mine and mill this Uranium was about 3% of a GigaWatt-year. Thus the energy produced is about 500 times more than the energy required to operate the mine.

Thanks for interesting info.
The report I cited on current proven and "reasonably assured speculative" uranium reserves is:
http://nuclearinfo.net/Nuclearpower/WebHomeAvailabilityOf ...
This report says that these recoverable reserves were:
· Proven: 4.7 million tons (as uranium)
· Speculative: 35 million tons
The nuclearinfo report defines "reserves" as those that are "recoverable with current technology and for the specified price" (which the report defines as $US130/kgU).
As I understand it, the reports which you cite list the world's estimated total uranium available from all sources, but that most of these sources do not meet the definition from nuclearinfo, in that it will take new technology to recover uranium from them at an economically viable price. Have I got this right?
The nuclearinfo report does say that with current technology, U235 is the only fuel for nuclear reactors, and this is only 0.72% of natural uranium, with the balance being U238.
Future technological developments could allow other nuclear fuels to be used, such as Thorium232, which is more abundant than uranium.
Future fast breeder reactors, also requiring new development work, could extend the life of the reserves by several hundred years. The report says "If reactors could be made to utilize Pu239 [plutonium], the potential of known reserves of uranium would be greatly extended since U238 could then be turned into a fuel."
The report say that the development of these new technologies would "provide enough fuel for many centuries of energy production". You mentioned a "trillion years"; maybe it's only a "billion", but who cares? It's a long, long time.
The point I made to Greyfalcon was that with current technology we have a limited supply of economically viable nuclear fuel (U235). R+D efforts will be required to develop commercial reactors to extend our fuel reserves (adding thorium, fast breeder reactors, etc.). New technology will also be required to commercially recover uranium at an economically feasible cost from many of the low grade sources mentioned in the first report you cited.
The second report you cited is very interesting. It shows that there is a lot of R+D work going on today worldwide to develop more efficient reactors beside the few major developments mentioned in the nuclearinfo report.
On top of all of this there is potential new nuclear fusion technology. What do you think of this as a long term alternate?
The R+D efforts required to develop all these new technologies could be partially funded by the proposed plan Lomborg describes.
(BTW your reference to the mine in Namibia and the numbers on the Forsmark power plant are interesting.)
From all the above it looks like we are not going to run out of electricical power in the foreseeable future.
Let's just hope we can get electrical power and, with it, clean drinking water to the hundreds of millions of people in the world that do not have access to either today.
Even though it is getting a lot less media attention today, this sounds to me to be a bigger problem than another 1 degrees C global warming over the next 50 or 100 years.

Hey josullivan58 and MarkUK,
You guys have to keep a sense of humor in this whole AGW debate. Don't take these things too seriously. Some of the true AGW believers are such dour pessimists that they have completely forgotten how to laugh.
These poor, unhappy souls are giving us the same, dismal "THE END IS NEAR!" message like the old pessimistic fundamentalist religious doomsday crackpots that you sometimes see on street corners or in places like New York's Central Park or London's Hyde Park.
These are the honest, but relatively harmless, individuals.
Some of them truly believe we are headed for imminent disaster due to AGW because we have sinned, and that we must repent now and this is no laughing matter.
Then there are others who are using this whole hysteria and guilt trip to their own personal advantage, i.e. to keep the public in fear and guilt so they will support a desired political course of action, which will bring them personal benefit.
And then there are those who can keep their sense of humor through this whole circus.
And you can both relax, it will all blow over in a couple of years and we will have a new "THE END IS NEAR!" hysteria for the media and politicians to feed on.
It's actually quite funny, but you've got to keep your sense of humor.
Just a bit of friendly advice.
Regards,
Max

However, you don't seem to get many responses, I guess for several reasons.
One is that it tends to be off topic
Another is, that although many sympathise with your message, I think it is bewilderingly too difficult for the audience you are addressing.
Another is that I don't recall you suggesting what might be doable and useful.
What is your audience supposed to do here with your latest shout below?
OVERPOPULATION ISSUE OVERLOOKED BY PRESIDENTIAL CANDIDATES
I think you might do better at a broader Greenie website, where climate change is a lesser subject of debate. For example, try GREEN OPTIONS and their associated sites
Several of us have mentioned the need for action to relieve the suffering of many millions in Africa as a much more important issue than the hysteria on AGW, and one such lengthy post directed to you was ignored by you in that part. Incidentally, such improvements would likely eventually reduce the birth-rate
So what is your recommendation for Africa?
Let AIDS really take over and reduce the population?
Send the CIA in and assassinate the Pope, then make a profit selling condoms?
But as I say this is not the best venue to discuss these things

No. It defines "Reasonably assured reserves (or proven reserves)". This is an industry term. Industry has no interest in proving reserves beyond what would be needed for a few decades. As soon as industry finds what it needs for the immediate future, it stops exploring. However, we know that finding more "reasonably assured reserves" at any time would easy, since uranium exploration is inexpensive in relation to oil exploration.
world-nuclear.org/info/inf75.html
From numerous published sources, the finding costs of crude oil have averaged around US$ 6/bbl over at least the past three decades. When finding costs of the two fuels are expressed in terms of their contained energy value, oil, at US$ 1050/MJ of energy, is about 300 times more expensive to find than uranium, at US$ 3.4/MJ. Similarly, the proportion of current market prices that finding costs comprise are lower for uranium. Its finding costs make up only 2% of the recent spot price of US$ 30/lb ($78/kgU), while the oil finding costs are 12% of a recent spot price of US$ 50/bbl.
By these measures, uranium is a very inexpensive energy source to replenish, as society has accepted far higher energy replacement costs to sustain oil resources.
Manacker wrote: it will take new technology to recover uranium from [the world's estimated total uranium available from all sources] at an economically viable price. Have I got this right?
No.
Please try reading the links again. Uranium mining is economically viable down to 1ppm -- which would provide an energy-return factor of 1.6, scaling current operations at the Rossing mine in Nambia -- using current technology. Therefore, current technology alone gives us an economically-viable uranium resource of 40 trillion tons. At an energy value that would put oil at $100, one kilogram of uranium is worth $1 million, and an average square meter of the earth's continental crust is worth $1 billion -- equal to a layer of pure solid gold, 6 feet thick -- just for the uranium and thorium it contains. Yet, mined uranium is sold today for only $20-$200/kg.
The price of mined-uranium could rise by more than a thousand-fold, and mined-uranium would still be economically viable.
Manacker wrote: there is potential new nuclear fusion technology. What do you think of this as a long term alternate?
Technologies are easier to develop, the greater the power-consumption of society. If fission-energy is continuously ramped-up at a rate of 10-trillion-fold-per-millennium (3.04% per year), fusion should be fairly easy to develop 4 or 5 centuries from now. There would be no need for fusion until then, and it probably would not be competitive until then. Any present directing-of-resources to fusion research is therefore irresponsible.
If the energy-consumption-growth of Earth-based civilisation levels off several centuries from now, then there will be no need for fusion energy for several thousands or millions of years.

It's a long, long time.
The total amount of the resource matters, even if it seems to be very large, when considering an exponentially-evolving energy scenario. I calculated that the 200 trillion tons of currently-economically-viable uranium and thorium in the earth's crust would fuel our current nuclear-electric power level for half a trillion years (or a full trillion years, if we use Bill Hannihan's figures). If civilization ramps up its power-consumption at a rate of 20-fold-per-century (3.04% per year), then that same 200-trillion-ton resource will last only half a millennium.
Manacker wrote: fast breeder reactors
These have no relevance for the present century, and little relevance several centuries into an exponentially-evolving energy-consumption scenario. If and when they are needed, it will be apparent enough. They will also be easy to develop at that time, since (as will be the case with fusion) resources needed for such development will be far more available. As is the case with regards to fusion, direction of resources toward the development of breeder reactors any time in the present century is, and would be, irresponsible.
Manacker wrote: It shows that there is a lot of R+D work going on today worldwide to develop more efficient reactors
Such R+D work is irrelevant. What needs to be currently researched is how to get rid of the Nuclear Regulatory Commission (NRC). If not for the NRC, nuclear reactors would be as ubiquitous, and evolve as fast, as automobiles.

Hey nucbuddy,
I got your point. Thanks for filling me in.
You wrote: "Technologies are easier to develop, the greater the power-consumption of society."
No argument on that observation; it has been confirmed by the historical record. Many have argued that there would have been no atomic bomb (and end of WWII) by 1945 if there had not been a TVA with all its surplus electrical power.
You wrote: "If fission-energy is continuously ramped-up at a rate of 10-trillion-fold-per-millennium (3.04% per year), fusion should be fairly easy to develop 4 or 5 centuries from now. There would be no need for fusion until then, and it probably would not be competitive until then. Any present directing-of-resources to fusion research is therefore irresponsible."
This makes sense and I assume you are also including solutions to the problem of safe disposal of nuclear waste.
Are you saying the same for development of reactors that can use thorium or fast breeder reactors, or do these technologies already exist on a commercially viable basis?
And if I understand you correctly, the R+D projects that are now underway are primarily for increasing fuel efficiency and reducing costs, not for developing basically new technology.
So, from what you have written, it looks like the current nuclear power generation technology can take over all future growth of electrical power generation in the developed world for the foreseeable future and gradually start to phase out older, less efficient fossil fuel plants.
With over 70% of its total power from nuclear plants, France has shown us that this can be done safely, cost effectively and efficiently. No "China syndrome" or "Chernobyl" here.
This is good news.
With all this being true, I cannot understand why all the environmental activist and lobbying organizations that are trying to curb CO2 emissions have not jumped on this bandwagon. It seems like a natural to me. Do you have an explanation for this?
Do they really want to solve the problems of dependency on dwindling fossil fuel resources and CO2 emissions, or is there some other hidden agenda?
Some of these same "green" groups fought against nuclear generation in the past with their "China syndrome" scare campaign. Are they now having a hard time changing stories to fit the new AGW campaign?
Why does IPCC not come out with a firm recommendation in support of nuclear generation for the bulk of all future power generation (at least in the developed world)?
This all does not make sense to me.
Got any answers?

Max

Looks like our discussion on Lomborg's proposal vs. the UN proposal has come to an end with neither of us having convinced the other, but let me throw this one at you, which is related. It basically boils down to: Andrew's statement that "climate change is real" is undoubtedly true, but is "climate change" relevant as one of the most important issues of our time, as some would have us believe?
I'll just toss out one example that puts this premise in question, for your comments.
All "extreme weather events" took around 20,000 lives per year over the period 2000-2006. These included: droughts, floods, windstorms (tornadoes, hurricanes, cyclones), slides, waves/surges, extreme heat, extreme cold and wild fires. This number has come down by a factor of ten as compared to the period 1900-1989, so it is highly unlikely that these deaths can be attributed to recent increased warming from anthropogenic greenhouse gas emissions.
http://www.csccc.info/reports/report_20.pdf
The World Health Organization (WHO) estimates that there are around 2.2 million per year worldwide who die from diarrheal diseases caused by poor sanitation and lack of clean drinking water.
http://www.who.int/water_sanitation_health/diseases/diarr ...
The WHO also estimates that another 1.6 million annual deaths in developing countries are caused by indoor air pollution from solid fuels, where there is no access to electrical power for cooking.
http://www.sciencedaily.com/releases/2006/02/060215090413 ...
Together these two factors cause almost two hundred times as many deaths worldwide as all extreme weather events combined.
Now these are not in trendy spots like Europe or the USA, but hundreds of millions of people (maybe as many as a billion) in the poorer countries of this world lack access to clean drinking water and electrical power today.
To solve this problem there will need to be new water treatment and distribution systems as well as new power generation plants and distribution systems in these developing countries.
To put this in perpective, the world average annual per capita power consumption is around 2,600 kwh. The top 10 countries average 17,000 kwh (USA is #9 at 13,000 kwh). The bottom twenty countries average only 140 kwh per person per year, and the very poorest are at around 30 kwh. That's one-third as much electrical power as a single 60-watt light bulb would use over a whole year if it burned 4 hours per day.
http://www.csccc.info/reports/report_20.pdf
The average for all the developing nations, including giants such as China and India, has been estimated at less than 1,500 kwh today. The most rapid growth in energy demand from 2004 to 2030 (2.5% per year) is projected for nations outside the OECD, compared with a growth rate of 0.6% per year in OECD energy use. GDP in purchasing power parity terms is expected to increase by 5.3 % per year on average in non-OECD nations, as compared with an average of 2.5 % per year for the OECD economies. So the good news is that "prosperity" is growing at a faster rate than energy demand in all economies, but particularly in the OECD nations. Are energy conservation actions working in the industrialized world? It sure looks like it.
http://www.eia.doe.gov/oiaf/ieo/highlights.html
The report forecasts that coal's share of total world power generation use is projected to increase from around 50% in 2004 to 54% in 2030. Nuclear generation is expected to decrease from currently 16% of the total to around 12%, as some EU countries start the politically mandated policy of phasing out existing nuclear plants. This is not too good for the EU members' stated goal of reducing CO2 emissions, but fortunately France is not following this "phase out" policy, and will probably meet its CO2 goals.
But we are talking about the very poorest countries at the bottom of the list, which currently have per capita GDP of less than $1 per day. Most of the growth in these countries will probably come from non-nuclear plants, primarily for political and security reasons, since many of these countries have unstable governments and some suffer from chronic tribal, ethnic or political warfare.
Some local power generation can come from diesel generators or "renewable" wind, solar and bio-mass generation and there may still be some potential hydroelectric projects, but the bulk will have to come from conventional power stations, most likely from coal-fired plants.
On balance it is clear that the higher CO2 emissions resulting from these new power plants will have a far smaller adverse affect on humanity than the benefit they will bring to these hundreds of millions of people that are deprived of clean water and electrical power today.
A computer model projected potential increase in extreme weather events from AGW is a "rich man's" problem that may cost a few thousand more lives worldwide some time in the future (although a direct cause-effect relationship is far from scientifically proven, and it may have no effect at all on climate-related deaths).
Dying from polluted drinking water and indoor air pollution are a "poor man's" (and woman's) problems, which directly cause millions of deaths per year today (with a well-established and undisputed cause-effect relationship).
So let's get our priorities right. If we take 75% of the money currently funding "climate research" and divert it into projects to provide clean drinking water and electrical power for these people, we will be doing far more to help humanity.
Climate scientists and others who earn from the current AGW industry will not like this proposal. There may also be those who argue that we should continue to let the people in these poor countries die, because this would help the global overpopulation problem, but this is a callous and inhumane argument.
What are your thoughts on all this?
Thanks for your input.

He assumes Funding climate science/tech/policy is mutually exclusive to funding other humanitarian efforts.
Lomborg loves to focus his analysis only on the short term. And if you do that, of course it's impossible for any long term issue to compare to a short term issue, IN the short term.
Especially when Lomborg assumes that climate change will have virtually no negative impact.
And those flawed assumptions as the basis of all of his arguments.
_
That said, have you had the chance to read through this webpage?
It goes over pretty much every point Lomborg puts forward, and counters it with a clear refutation.
http://lomborg-errors.dk
_
For instance his use of the IPCC Sea Level rise table as a corner stone of many of his arguements.
Meanwhile the IPCC points out:
"Because understanding of some important effects driving sea level rise is too limited, this report does not assess the likelihood, nor provide a best estimate or an upper bound for sea level rise. The projections do not include uncertainties in climate-carbon cycle feedbacks nor the full effects of changes in ice sheet flow, therefore the upper values of the ranges are not to be considered upper bounds for sea level rise."

Went through the critique of Lomborg's "The Skeptical Environmentalist" on the site which you cited.
Only took the first twenty "critiques" of Chapter 1: "Things are getting better".
Out of these I found 6 listed under the category "FLAW". On closer examination, 4 of these 6 were not refuted in the critique, but there was some objection to the wording used by L (examples: referring to equal "rights" for animals, rather than equal "consideration", use of word "categorically" where the critics found this was unjustified). One FLAW was refuted with references (fertilizer use). Another FLAW was incorrectly refuted (no increase in hurricanes); L has been validated on this claim by reports, which the critics ignored.
So far the score is 5:1 for Lomborg.
Then there was one "ERROR" listed, where L wrote 1% of Indonesia forests had been destroyed and the critics referred to a report that states that this should have been 4 to 5%.
Assuming the critic's report is correct, L was refuted.
So the score is now 5:2 for Lomborg
Then there were 7 listed under "COMMENT". Of these, 3 were simply "comments" (not refuting errors); 2 were statements by L that were questioned (without any facts to refute them), 1 was an objection to L's use of word "entirely" (without providing any specific references to refute this word). One COMMENT quoted a WWF report that confirmed 1997 as record forest fire year. Assuming this report is correct, L was refuted.
So the score is now 11:3 for Lomborg.
There were 4 listed under "GROUNDLESS DEROGATION". In none of these was L refuted, but he was chided for his wording and criticized in one case for not providing detailed backup.
So the score is now 15:3 for Lomborg.
There was one listed as "UNDUE PRECISION". Again, L was not refuted with any facts or counterclaims but was questioned for the precision of his sources.
So the score is now 16:3 for Lomborg.
A final critique was listed as "INCONSISTENCY". L was not refuted but was critiqued for discussing "local" food shortages, when he should have discussed "global" shortages.
So the score ended up 17:3 for Lomborg.
I do not plan to go through the hundreds of other items in this critique, as I suspect the ratio will be about the same throughout.
This is a very weak critique of Lomborg's book that really does not say much.
Will get back to you on your other points.

Back to part 2 of my response to your blog on Lomborg.
You wrote: "He assumes Funding climate science/tech/policy is mutually exclusive to funding other humanitarian efforts."
I cannot chide Lomborg for his assumption that there is a finite amount of money available for doing things. To put it in one pocket you have to take it out of another pocket somewhere. An undue emphasis (by the media, by the governments, etc.) on a perceived climate crisis means that other crises are getting less emphasis and funding.
A good example of this is the budget of the USA. The high level of emphasis and spending on the war in Iraq took away from spending on other (mostly domestic) programs and has taken away from future generations by running up record deficits; the counterargument that taxes could have been raised to cover the costs of the war just means that it would then have come out of taxpayers' pockets today rather than in the future.
You also wrote: "Lomborg loves to focus his analysis only on the short term. And if you do that, of course it's impossible for any long term issue to compare to a short term issue, IN the short term."
I read both of his books and many of his published articles. I do not see this purely short-term focus. What I do see is an emphasis on solving problems that have real immediate consequences that can be well defined and which can be resolved by acting now rather than on those that may have long term consequences that are only vaguely defined and which can probably not be changed very much by actions taken today.
In other words, if you truly believe (a) that AGW is the most important problem of our planet today and (b) that we will face certain disaster in the near to intermediate future due to this problem if we do not take specific action today and (c) that we have defined the specific action required and (d) that if we do take this specific action today we can avert the disastrous consequences which will otherwise occur, then the time to act is certainly now, and all other programs become relatively inimportant.
This would be true crisis management (a.k.a. "blood, sweat and tears"), such as the governments of the UK and USA were forced to do during WWII.
If you do not believe (a) through (d) above, which Lomborg plus many others in this world do not, then AGW no longer represents a greater challenge than many others out there today.
I would specifically exclude the related challenges of increasing energy efficiency, reducing waste, eliminating pollution, reducing dependency on a dwindling fossil fuel supply coming from politically unstable areas, etc. Responding to these challenges may have an effect on AGW but they have justifications of their own, which have little to do with AGW per se.
Coming back to my earlier post, I also think it is difficult to argue that the AGW crisis which may be responsible for 20,000 deaths per year worldwide today (with a highly speculative cause and effect relationship) is more important than the crisis of no supply of clean drinking water and electrical power for hundreds of millions of people, which directly leads to the death of 3.8 million people annually.
It is all a matter of perspective and I think the AGW proponents have lost this perspective in trying to promote their favorite cause to the "greatest potential future disaster facing our planet".

One more point regarding Lomborg. In your critique of his statements you said: "For instance his use of the IPCC Sea Level rise table as a corner stone of many of his arguments." You cite a gristmill "what do we know?" reference that supposedly clears this up and hints at much higher sea level rise than that projected by IPCC.
Quoting from your gristmill reference:
"Because understanding of some important effects driving sea level rise is too limited, this report does not assess the likelihood, nor provide a best estimate or an upper bound for sea level rise. Table SPM.1 shows model-based projections of global average sea level rise for 2090-2099. The projections do not include uncertainties in climate-carbon cycle feedbacks nor the full effects of changes in ice sheet flow, therefore the upper values of the ranges are not to be considered upper bounds for sea level rise. They include a contribution from increased Greenland and Antarctic ice flow at the rates observed for 1993-2003, but this could increase or decrease in the future."
This says there are "uncertainties" because the "understanding of some important effects driving sea level rise is too limited".
This is anything but a disaster prediction. It is simply an admission that scientists do not know what is going to happen to sea levels.
But the weakest point in the above disclaimer is the statement that the projections for the future "include a contribution from increased Greenland and Antarctic ice flow at the rates observed for 1993-2003".
In SPM 2007 IPCC claims a net mass loss of Antarctic ice 1993-2003 due to anthropogenic global warming (AGW) with a corresponding rise in sea level over the same period (pp.5,7) equivalent to a sea level rise of 0.21 mm/year over the period. The record based on 11 years of continuous actual measurements covering the same period shows no shrinking, but an increase with a corresponding lowering of sea level over the period. This report was ignored by IPCC.
http://bowfell.geol.ucl.ac.uk/~lidunka/EPSS-papers/djw3.p ...
IPCC claims a net mass loss of Greenland ice 1993-2003 due to AGW with a corresponding rise in sea level over the same period (pp.5,7) equivalent to a sea level rise of 0.21 mm/year over the period.. The record based on 11 years of continuous actual measurements covering the same period shows no shrinking, but an increase with a corresponding lowering of sea level over the period.
http://www.eurekalert.org/pub_releases/2005-11/esa-eas110 ...
http://www.sciencemag.org/cgi/content/abstract/1115356v1
So the "rates observed for 1993-2003" actually showed net GROWTH of both ice sheets, based on the published reports cited above, yet IPCC claimed net LOSS in both ice sheets, and used this 1993-2003 "contribution from increased Greenland and Antarctic ice flow" in arriving at its "model-based projections of global average sea level rise for 2090-2099".
Hmmm...
This certainly does seem to confirm their statement that there are "uncertainties" because the "understanding of some important effects driving sea level rise is too limited".
But it does not in any way discredit Lomborg.

Looks like you have lost interest in our discussion on the relevance of climate change, Lomborg, etc.
But let's go back to Andrew's lead story:
"Climate change is real"
This has been true for our planet for billions of years, including major ice ages, periods much warmer than today, etc.
For a good snapshot of climate changes during historical times, read the chapter "Warming and Cooling in Human History" in the Singer/Avery book, "Unstoppable Global Warming".
For a good explanation why Earth does not resemble either Venus or Mars, read the chapter "Habitable Zones of the Universe" in the Ward/Brownlee book, "Rare Earth".
Good background info.

Did you see that report that they emit lots of ultra-micro-fine particles which are a health hazard that becomes concentrated in most office air re-circulation environments?
Is it possible that corporate interests are mainly interested in the bottom line and that academic institutions do not want to offend their peer institutions etc ad nauseam carborundum?
Oh thou simplistic soul TGOT!

Unfortunately much of the water in the troposphere is in the form of ice crystals and this makes it difficult to accurately measure the humidity there according to papers I have read on the subject. Another difficulty is that accurate data on tropospheric humidity is almost nonexistent for any substantial time period.
I think that the main contributor to watch in this case is jet exhaust. The CO2 and water vapor produced by jet engines is produced and injected directly into the upper troposphere which bypasses all of the natural mechanisms for getting these gases up there. So jet exhaust establishes an unnatural level of these gases and then keeps replenishing and/or increasing that level of gases.
At the same time burning fossil fuels at ground level creates enough water vapor to change the concentration of water vapor at that level and this might make it significantly less likely for excess tropospheric water to drop into lower regions of the atmosphere. Once air is saturated with water it cannot hold any more so no water from higher levels could move down until the lower water drops as rain.

Now that was an interesting contribution, but what you are scratching the surface of is very complicated.
Do you have any information that reaches an understanding of the total system starting at the surface(s) through to the limits of Cirrus clouds?
Even if not, I hope you keep in touch with developments in that science and keep us up to date.
Incidentally, is this topic not very close to Dr Dessler's speciality?

1) A nice powerpoint presentation http://209.85.165.104/search?q=cache:OcFRM93wvuoJ:www.cos ...
There is debate on the accuracy of data retrieved from various sources http://www.ghcc.msfc.nasa.gov/irgrp/UTH_details.html
A very nice collection of papers on related topics
http://www.gfdl.noaa.gov/reference/bibliography/authors/s ...
Good paper from NASA http://www.nasa.gov/centers/goddard/news/topstory/2004/03 ...
This one is based on Radiosonde data and has a good collection of references http://ams.allenpress.com/perlserv/?request=get-document& ...(2002)003%3C0026%3ALTHTRI%3E2.0.CO%3B2&ct=1
This one is on measuring Tropospheric humidity from aircraft http://www.aero.jussieu.fr/~sparc/News11/TroposphericH2O. ...
Wade through all this and you will have a pretty good idea on where we are with the subject. At the moment there are several satellites recording data on Tropospheric humidity and as this data accumulates I think a much better picture will emerge but unfortunately the data record only goes back for a relatively short time and that makes it more difficult to show definite long term trends.

The normative transitive verb 'troll' has several extensions including several diverse nouns. In the blogosphere it's accepted vi meaning is to: Lure an on-line response with a deliberately false statement. This is derived from: to go fishing by trailing an artificial lure.
What pray were you attempting to define?

give me time to go through all that! It looks very interesting but I'm not very familiar with it, so I need more time to respond, unless someone else can step-in.
My intuitive feeling is that the effect of aircraft vapour trails up there must be rather tiny in the scale of that huge huge sky up there, but I have absolutely no data to confirm my intuition.
Another thing that I'm aware of but also without any sense of scale is the break-down of methane to also add H2O up there.
There is also talk of dimers and trimers of H20, but again, I'm not top gun on this.
Max, if you are around, can you help with the chemistry; ions and all that S**t?

If your main interest is in aircraft vapour trails, I would think it would be valuable (if possible) to compare high traffic areas such as Europe/USA with the sparse.
This made me remember the following post over at ClimateResistance highlighting that the IPCC's WG2 report (repeat 2 not 1) discusses among other things regional variations in data, seemingly apolitically, that might be relevant. It also takes you to another independent opinion piece, which is at the very least very thought provoking.
http://www.climate-resistance.org/2007/12/physician-heal- ...
Wasn't there some stuff to compare before and after 9/11?.....I forget the details but perhaps you could do an advanced Google. (dimming?)
Concerning your referenced links, I don't have power-point set-up or a great deal of time available, but briefly:
Was VERY interesting, and is co-authored by Andrew Dessler. I doubt if he (as host here) would discuss it openly here with you.....perhaps try private Email.....he does like to send Emails to others?
May be a bad link?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I think you could do better at a scientific forum such as at ClimateAudit Bulletin Board (BB) @:
http://www.climateaudit.org/phpBB3/index.php (Its main index)
This place is crawling with physicists and other scientific types. The index lists many families of "climate" topics, for instance if you click "Physics Issues" there are currently 30 topics and almost 1000 comments, or there is "Unthreaded" with 93 topics etc. where you can toss-in anything scientific you like. I'm sure you could cut and paste your stuff from here and shoe-horn it in over there and get a lot more help than is the potential here. (Here is a not very scientific)
The BB is quite separate to the main Web-log of ClimateAudit, and there may well be other threads there of interest. The separate forum is apparently intended to divert distractions or clutter from the main blogs. Nevertheless, some participants enjoy greater flexibility on the BB.
I hope to meet-up with you there,
Regards, Bob
