350 ppm or bust Hansen paper released; WaPo fails to link to Grist	David Roberts	07 Apr 2008	Gristmill
Several posts on this site have mentioned a recent paper from James Hansen et al. -- Target CO2: Where Should Humanity Aim? (PDF) -- which argues that the official E.U. target of 550 ppm global atmospheric CO2 is far too high, and that anything over 350 ppm risks putting human beings in a world radically different than anything they've ever known. The final version of the paper is now up, and there's been some good news coverage. For a good overview, see Ed Pil ...

Sorry, deniers Research finds (once again) that climate change is not caused by cosmic rays	Joseph Romm	06 Apr 2008	Gristmill
One more denier talking point has been debunked by scientists using actual observations. You can read the Science News article here, which explains, 'New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases.' You can read the original article, just published by the Institute of Physics' Environmental Research Letters, 'Testing the proposed causal link between cosmic rays and cloud co ...

Matt Drudge's misleading mashup bolsters right-wing fantasy World Drudge hijacks headlines to sell global warming denial	Brad Johnson	04 Apr 2008	Gristmill
From the Think Progress Wonk Room. Atop the Drudge Report right now: Do the stories behind these headlines tell the tale that global warming alarmists have 'hijacked' the political debate despite a 'lack of natural disasters' and no global warming 'since 1998'? No. Let's review: DRUDGE HEADLINE #1: REPORT: GLOBAL TEMPS 'HAVE NOT RISEN SINCE 1998' This claim has been thoroughly debunked every time it's popped up. The oil-backed global ...

More from the delayer-1000 du jour Why did Nature run Pielke's pointless, misleading, embarrassing nonsense?	Joseph Romm	02 Apr 2008	Gristmill
The usually thoughtful journal Nature has just published a pointless and misleading -- if not outright dangerous -- commentary by delayer-1000 du jour, Roger Pielke, Jr., along with Christopher Green, who, as we've seen, is another aspiring delayer. It will be no surprise to learn the central point of their essay, ironically titled 'Dangerous Assumptions' (available here [PDF] or here, with a subscription), is: 'Enormous advances in energy technology will be needed to s ...

The biggest source of mistakes: carbon vs. carbon dioxide A factor of 3.67 makes a big difference when discussing climate	Joseph Romm	25 Mar 2008	Gristmill
The biggest source of confusion and errors in climate discussions probably concerns 'carbon' versus 'carbon dioxide.' I was reminded of this last week when I saw an analysis done for a major environmental group that confused the two and hence was wrong by a large factor (3.67). The paragraph I usually include in my writing: Some people use carbon rather than carbon dioxide as a metric. The fraction of carbon in carbon dioxide is the ratio of their weights. The atomic ...

Fair and balanced? NASA's Hansen responds to NYT's Revkin	Joseph Romm	24 Mar 2008	Gristmill
This post ends with an exclusive look at James Hansen's response to NYT journalist Andy Revkin's piece commenting on Hansen's (draft) article on why we need a CO2 target of 350 ppm. But first the backstory. Revkin used me as the 'balance' for his piece: Some longtime champions of Dr. Hansen, including the Climate Progress blogger Joe Romm, see some significant gaps in the paper (it is a draft still) and part ways with Dr. Hansen over whether such a goal is remotely f ...

The Hansen (et al.) ultimatum Get back to 350 ppm or risk an ice-free planet	Joseph Romm	20 Mar 2008	Gristmill
Here is the draft [PDF] of the long-awaited defense of why we need an ultimate target of 350 ppm for atmospheric carbon dioxide, by NASA's James Hansen et al., titled 'Target Atmospheric CO2: Where Should Humanity Aim?' (Yes, they know we're already at 385 ppm and rising 2 ppm a year.) The paper does suffer from one analytical weakness that makes it a tad less dire than it appears -- and some people believe the core element of this analysis is wrong (see very end of ...

Going, going ... Record global glacial melt	Joseph Romm	18 Mar 2008	Gristmill
'Record Glacier Thinning Means No Time to Waste on Agreeing New International Climate Regime,' said the U.N. Environment Programme on Sunday. That statement is based on the data of the World Glacier Monitoring Service, which 'has been tracking the fate of glaciers for over a century. Continuous data series of annual mass balance, expressed as thickness change, are available for 30 reference glaciers since 1980.' Here's the mean annual specific net balance: The Servi ...

L.A. Times linked to lame climate coverage CO2's connection to global warming is not murky	Joseph Romm	14 Mar 2008	Gristmill
I like the L.A. Times. They do some of the best reporting on environmental issues. So I'm reading a pretty good piece on how the EPA administrator overruled his science advisers on the recent ozone ruling (more on that in a later post), and I come to this remarkable paragraph that shows how the president himself actually intervened to weaken the EPA regulations: President Bush intervened at the 11th hour and turned down a second proposal by the EPA staff that w ...

Climate change is back, baby! Where is the media coverage of February's incredible warming and extreme weather?	Joseph Romm	13 Mar 2008	Gristmill
Well, that record cooling trend in January, which was solid evidence (to some) that human-caused global warming was at an end, melted away as fast as the summer ice in the Arctic. Not only did February begin a frighteningly unsustainable warming trend for this year, it saw a record number of tornadoes. Climate change is making a comeback! In your face, delayer-1000s! And as Jon Stewart -- or the Pope -- might say, damn you, polluters! But where is the news covera ...

What price the future?	Ryan Avent	11 Mar 2008	Gristmill
Jim Manzi, with whom I have debated warming policy responses before, has a problem with The Washington Post's coverage of new studies on climate change. He writes: The premise of the story by Juliet Eilperin is well-expressed by its headline: 'Carbon Output Must Near Zero To Avert Danger, New Studies Say'. Eilperin prominently quotes Carnegie Institution senior scientist Ken Caldeira, co-author of one of the studies promoted by the article, who says: 'The question is, ...

Four hundred skeptics? Try 19 The Heartland conference recycles the usual climate change skeptics in its speakers list	Andrew Dessler	06 Mar 2008	Gristmill
The New York Times carried this interesting write-up of the Heartland Institute's 2008 International Conference on Climate Change. For those not familiar with this conference, it's like a scientific meeting on climate change -- without the science. The NYT article concluded with this statement, which pretty much sums it up: The meeting was largely framed around science, but after the luncheon, when an organizer made an announcement asking all of the scientis ...

Media enable denier spin, part two What if the MSM simply can't cover humanity's self-destruction?	Joseph Romm	06 Mar 2008	Gristmill
If those who counsel inaction and delay succeed, billions of humans will suffer unimaginable misery and chaos while most other species will simply go extinct. Maybe the best one line description of our current situation I have read is: It may seem impossible to imagine that a technologically advanced society could choose, in essence, to destroy itself, but that is what we are now in the process of doing. That's the final sentence in Elizabeth Kolbert's fine glob ...

A passing trend Hansen throws cold water on cooling climate claim	Joseph Romm	05 Mar 2008	Gristmill
NASA's James Hansen has weighed in (PDF) to ... ... expose the recent nonsense that has appeared in the blogosphere, to the effect that recent cooling has wiped out global warming of the past century, and the Earth may be headed into an ice age. On the contrary, these misleaders have foolishly (or devilishly) fixated on a natural fluctuation that will soon disappear. As Hansen explains: Weather fluctuations or 'noise' have a noticeable effect even on mo ...

Dismal science Do Big Oil and Big Tobacco share a similar smokescreen?	Miles Grant	04 Mar 2008	Gristmill
Stepping into the Heartland Institute's '2008 International Conference on Climate Change' was like walking into an alternate reality. To the rest of us, climate science is settled, the solutions are sensible, and the time for action is now. But in the Marriott Grand Marquis Times Square, the only science comes from industry-funded think tanks; climate action will destroy humanity; and the underdog in this fight is ExxonMobil.

California waiver update	David Roberts	04 Mar 2008	Gristmill
Earlier this year I wrote about a new (EPA-sponsored) study showing that increased CO2 in the atmosphere is directly correlated with increased ozone, particulates, and carcinogens in the air. Since California suffers disproportionately from those traditional air pollutants, it follows that California does have "extraordinary and compelling conditions" in the face of climate change, and the EPA's decision to deny Cali's waiver was bogus. Now the author of th ...

The plot to destroy America	Joseph Romm	04 Mar 2008	Gristmill
Suppose you knew about a plot whose inevitable outcome would be to undermine the health and well-being of your children, their children, and the next 50 generations. Yes, hundreds of educated people -- mostly Americans -- are assembling in New York right now for just two purposes: Sharing the techniques needed to block vital action that could save billions of people from suffering and misery. Spreading long-debunked disinformation while masquerading as exper ...

You're ridin' high in April, shot down in May Climate change skeptics say we should note, not hype	Sir Oolius	03 Mar 2008	Gristmill
Revkin: Mr. Morano, in an e-mail message, was undaunted, saying turnabout is fair play: 'Fair is fair. Noting (not hyping) an unusually harsh global winter is merely pointing out the obvious. Dissenters of a man-made 'climate crisis' are using the reality of this record-breaking winter to expose the silly warming alarmism that the news media and some scientists have been ceaselessly promoting for decades.' And then there's this: 'Earth's 'Fever' Breaks: Global Cooli ...

Media enable denier spin, part one A (sort of) cold January doesn't mean climate stopped warming	Joseph Romm	03 Mar 2008	Gristmill
I fully understand why spreaders of climate disinformation have hyped up a (sort-of) cold January as if it somehow provided scientific evidence to support their campaign to undermine the well-established scientific understanding of human-caused climate change. That's their job (literally, in many cases). But I can't understand why the media keep treating such disinformers as if they were a genuine part of the scientific process who deserve free publicity, rather ...

'Stabilizing climate requires near-zero emissions' A new climate science paper calls for dramatic action	Joseph Romm	28 Feb 2008	Gristmill
Avoiding climate catastrophe will probably require going to near-zero net emissions of greenhouse gases this century. That is the conclusion of a new paper in Geophysical Research Letters (subs. req'd) co-authored by one of my favorite climate scientists, Ken Caldeira, whose papers always merit attention. Here is the abstract: Current international climate mitigation efforts aim to stabilize levels of greenhouse gases in the atmosphere. However, human-induced cl ...

Disputing the 'consensus' on global warming Climate science doesn't rely on a consensus of opinion	Joseph Romm	27 Feb 2008	Gristmill
Salon liked my post 'How do we really know humans are causing global warming?' but wanted something more in-depth and ... serious. The result is 'The cold truth about climate change: Deniers say there's no consensus about global warming. Well, there's not. There's well-tested science and real-world observations [that are much more worrisome].' James Hansen read the first draft and wrote me back, 'Very important for the public to understand this -- why has nobody ar ...

Another one bites the dust Climate change myth debunked: scientists did not predict new ice age	Andrew Dessler	26 Feb 2008	Gristmill
Over on his blog, John Fleck dispatches one of the most ridiculous urban legends of climate change: that scientists in the 1970s were predicting that an ice age was impending. John and his colleagues, Thomas Peterson and William Connolly, point out that, even in the 1970s, most scientists thought that global warming was the dominant problem. It should also be pointed out that those worried about global cooling did not necessarily dispute the fact that carbon ...
