What's happening in the world of Brave Heresy? RPJr. is at it again	David Roberts	20 May 2008	Gristmill
Roger Pielke Jr., last seen bobbing and weaving in an online bout with an Actual Scientist -- and getting pummeled -- can now be found in a story in the Moonie-owned, far-right Washington Times: Roger A. Pielke, environmental studies professor at the University of Colorado, and not previously a global warming skeptic, reacted to the Nature article: 'Climate models are of no practical use beyond providing some intellectual authority in the promotional battle over ...

CJR panel on climate journalism	David Roberts	20 May 2008	Gristmill
The Columbia Journalism Review recently held a roundtable on climate journalism: There were three journalists: Andrew Revkin, the New York Times's lead climate reporter/blogger; Bill Blakemore, who has spearheaded climate coverage at ABC News for the last four years; and John Rennie, the editor in chief of Scientific American who recently helped craft two issues on climate change that have sold better any other issue in the magazine's long history. And there were two ...

Cause and effect Human-caused warming is resulting in a broad range of impacts across the globe	Joseph Romm	15 May 2008	Gristmill
Nature has published the first article to 'formally link observed global changes in physical and biological systems to human-induced climate change, predominantly from increasing greenhouse gases.' See news story here and the article, 'Attributing physical and biological impacts to anthropogenic climate change' (subs. req'd, abstract below). NASA's discussion of the piece here explains, 'human-caused climate change has made an impact on a wide range of Earth's natur ...

Our tails get in the way The problems and principles of energy descent	Sharon Astyk	15 May 2008	Gristmill
'How did you get there, Roo?' asked Piglet. 'On Tigger's back! And Tiggers can't climb downwards, because their tails get in the way, only upwards, and Tigger forgot about that when we started, and he's only just remembered. So we've got to stay here for ever and ever -- unless we go higher. What did you say, Tigger? Oh, Tigger says if we go higher we shan't be able to see Piglet's house so well, so we're going to stop here.' -- A.A. Milne, 'The House At Pooh Corn ...

The jewel of denial The delayers' paradox	Joseph Romm	14 May 2008	Gristmill
The primary goal of the global warming deniers and their disciples is to waste time and delay action, which is why I prefer to call them delayers. (This post is inspired by the surprising finding that only 27 percent of conservatives say the earth is warming because of human activity, such as burning fossil fuels.) The delayers' paradox The deniers and delayers are those who argue that failing to embrace strict reductions in greenhouse-gas emissions will not lead to s ...

The world at 350 A last chance for civilization	Guest author	12 May 2008	Gristmill
This guest essay from environmental author and activist Bill McKibben was originally published at TomDispatch, and is reprinted here with Tom's kind permission. ----- Even for Americans, constitutionally convinced that there will always be a second act, and a third, and a do-over after that, and, if necessary, a little public repentance and forgiveness and a Brand New Start -- even for us, the world looks a little Terminal right now. It's not just the economy. W ...

Coal moratorium now! Preventing dirty coal plants is the most urgent climate policy	Joseph Romm	07 May 2008	Gristmill
A livable climate can (probably) survive the burning of almost all of the world's conventional oil and gas -- but not if we also burn even half the coal (see here [PDF] and figure below). So the top priority for any climate policy must be to stop the building of traditional coal plants -- which is why that has become the top priority of NASA's James Hansen (see here). The next priority is to replace existing coal plants with carbon-free power, which could include c ...

In their humble overestimation ... IPCC likely too optimistic about recoverable coal	Andrew Dessler	06 May 2008	Gristmill
Anyone interested in the climate should watch this talk by Professor David Rutledge from Caltech. He makes the argument that there are a lot less recoverable fossil fuels than assumed by just about everyone, including the IPCC emissions scenarios. His conclusion is that even if we burn all the fossil fuels on the planet, atmospheric carbon dioxide will not exceed 500 ppm. Is he right? Perhaps, although his analysis considers only conventional fossil fuels and does ...

Nature article on 'cooling' confuses media, deniers Next decade may see rapid warming, not cooling	Joseph Romm	04 May 2008	Gristmill
The Nature article ($ub. req'd) that has caused so much angst about the possibility that we are entering a decade of cooling -- 'Advancing decadal-scale climate prediction in the North Atlantic sector' -- has been widely misreported. I base this in part on direct communication with the lead author. In fact, with the caveat from the authors that the study should be viewed as preliminary, and should not be used for year-by-year predictions, it is more accurate to say t ...

Has global warming stopped? Climate change must be examined over decades, not years	Andrew Dessler	02 May 2008	Gristmill
There has been a lot of nonsense written about the lack of much if any warming over the last few years. It's not a new argument -- in fact, I blogged about it here -- but like an axe-wielding psycho from a cheap horror flick, it just keeps coming back. At times like this, it is always useful to look at the data. The figure below shows the temperature anomalies (relative to the 1961-1991 average) from 1850 to 2007. The data are the Hadley HadCRUT3v analysis. A ...

Skeptics lie; news at 11 DeSmogBlog uncovers Heartland lies	David Roberts	02 May 2008	Gristmill
The right-wing Heartland Institute has been making a big fuss about "500 Scientists with Documented Doubts of Man-Made Global Warming Scares." Five hundred skeptical scientists? Sounds bad! Kevin Grandia at DeSmogBlog had the radical idea of actually contacting the scientists, to see if they are being accurately characterized by Heartland. You see where this is going, right? In less than 24 hours, Grandia received three dozen outraged replies from scienti ...

650 million years in 94 minutes A History Channel production on climate is worthwhile	JMG	01 May 2008	Gristmill
A coworker lent me an amazing piece of work called A Global Warning? It does an excellent job illustrating the chaotic nature of terrestrial climate and explaining the theories behind some of the most dramatic climate transitions. It's not a perfect movie, but if you won't read With Speed and Violence, it's probably the best thing there is. It gets into both ocean clathrates (methane hydrate crystals) and the melting permafrost (more methane). Best of all, not a single d ...

Is 450 ppm (or less) politically possible? Part 3: The breakthrough technology illusion Existing technology is faster and far more practical than hypothetical new inventions	Joseph Romm	30 Apr 2008	Gristmill
This post will explain why some sort of massive government Apollo program or Manhattan project to develop new breakthrough technologies is not a priority component of the effort to stabilize at 450 ppm. Put more quantitatively, the question is, what are the chances that multiple (4 to 8+) carbon-free technologies that do not exist today can each deliver the equivalent of 350 gigawatts baseload power (about 2.8 billion megawatt-hours a year) and/or 160 billion gallo ...

Cool as a Still-Warming Cucumber Next decade could be cooler than expected, says study		30 Apr 2008	News
Posted at 11:56 AM on 30 Apr 2008 Natural shifts in ocean circulation may trump human-caused warming over the next decade, causing global temperatures to cool slightly, says new research published in the journal Nature. But hang on to your pessimism: "Just to make things clear, we are not stating that anthropogenic climate change won't be as bad as previously thought" over the long run, says research ...

Me on a podcast	David Roberts	29 Apr 2008	Gristmill
I am on this week's podcast from PolticalAffairs.net. I'll confess when the PA guy called me I didn't know it was a record of 'Marxist thought online,' but hey, let a thousand flowers bloom. As it happens I was talking about a market-based carbon policy, kind of an odd subject for a Marxist podcast, but it was fun. If you listen closely, you can hear me stirring my lunch on the stove as I talk. Multitasking might explain why I was talking so damn slowly. It sounds like ...

Earth Day preachin' By caring for God's creatures, we avert a second flood	Ken Ward	29 Apr 2008	Gristmill
This is a speech I delivered on Earth Day, April 20, 2008, at the Unitarian-Universalist First Church in Jamaica Plain, Mass. A software glitch prevented its publication on that day, but I believe it's still worth sharing. As Kurt Vonnegut once said, 'I wish I could bring light ... but there is no light. Everything is going to become unimaginably worse. If I lied to you about that, you would sense that I'd lied to you, and that would be another cause for gloom, and w ...

NOAA news isn't good news Atmospheric carbon dioxide, methane rise sharply in 2007	Joseph Romm	24 Apr 2008	Gristmill
The news from NOAA is that all our dawdling on climate action this decade is having real impact on the atmosphere: Concentrations of CO2 jumped 2.4 ppm in 2007, taking us to 385 ppm (preindustrial levels hovered around 280 through 1850). That is an increase of 0.6 percent (or 19 billion tons). If we stay at that growth rate, we'll be at 465 ppm by 2050 -- and that assumes (improbably) that the various carbon sinks don't keep saturating (see here and here). L ...

Burning ice, ice, baby Methane hydrates: What's the worst -- and best -- that could happen?	Joseph Romm	17 Apr 2008	Gristmill
Methane hydrates (or clathrates), 'burning ice,' are worth understanding because they could affect the climate for better or worse. You can get the basics here on ... ... a solid form of water that contains a large amount of methane within its crystal structure [that] occur both in deep sedimentary structures, and as outcrops on the ocean floor. The worst that could happen is a climate catastrophe if they were released suddenly, as some people believed hap ...

The flaccid mind of Stephen Johnson National Journal on the EPA tailspin	Joseph Romm	17 Apr 2008	Gristmill
The following post is by Earl Killian, guest blogger at Climate Progress. ----- The U.S. Environmental Protection Agency has been failing spectacularly to do what the law requires, as determined by numerous federal judges (including the Supreme Court). For a more in-depth look, consider a pair of articles by Margaret Kriz in the National Journal. 'Vanishing Act' looks at many of the failures of the EPA. 'The President's Man' presents an interview with EPA Administrat ...

Notable quotable	David Roberts	17 Apr 2008	Gristmill
'Emissions are growing much faster than we'd thought, the absorptive capacity of the planet is less than we'd thought, the risks of greenhouse gases are potentially bigger than more cautious estimates, and the speed of climate change seems to be faster.' -- Nicholas Stern, author of the seminal Stern Review on the Economics of Climate Change, on why he thinks his report underestimated the danger of global warming

A decarbonization story: Part 1 Why a carbon price beats technology breakthroughs	Joseph Romm	15 Apr 2008	Gristmill
The decarbonization data makes clear that if you want to beat 450 ppm and avoid catastrophic climate impacts, a significant price for carbon (plus aggressive technology deployment) is much more important than technology breakthroughs. That is a central point of this post. That is what I learned in the mid-1990s when I helped to run the billion-dollar office at DOE in charge of federal clean energy technology breakthroughs and deployment -- and had the chance to wor ...

Breaking: The great ice age of 2008 is finally over -- next stop, Venus! One month's worth of data laughable as proof of global cooling	Joseph Romm	14 Apr 2008	Gristmill
A top NASA scientist just emailed me the breaking news: 'The ice age expired!' Even more shocking: the rate of warming this year has been just about unprecedented in the historical record -- even faster than I had predicted just last month based on the NASA data from February. Just look at the NASA Goddard Institute for Space Studies dataset. While January's land-ocean global temperature was a mere +0.12 degrees C above the the 1951-1980 average and the February ...

What's Your Hurricane? Link between climate change and stronger hurricanes becomes fuzzier		14 Apr 2008	News
Posted at 3:24 PM on 14 Apr 2008 Climate change may not in fact make hurricanes more frequent and intense, says new research published in the Bulletin of the American Meteorological Society. While other climate models have reached similar conclusions, this study is notable for having as its lead author atmospheric scientist Kerry Emanuel, who was one of the first to suggest a link between warming and stro ...
