Climate Code Red The case for a sustainability emergency	Tom Athanasiou	06 Feb 2008	Gristmill
The pressure to soft-pedal is very, very high. I know because I feel it. I'm tempted. I do not wish to be dismissed as an apocalyptic. So when I read, in this fine and even astonishing report, that 'politics as usual' must be cast aside, and quickly, there's something in me that balks. After all, the mainline debate at Bali was about a '25-40% cut by 2020' for the developed countries. Isn't this enough? Doesn't it tell us that we're already moving as quickly as ...

Dr. Hansen to Dr. Merkel Carbon is forever -- so ban new traditional coal plants now	Joseph Romm	24 Jan 2008	Gristmill
Another clear statement (PDF) from the nation's top climate scientist on the scientific need for a dramatic change in global coal policy -- this time addressed to the German chancellor, a fellow physicist. He points out that: The fact that energy and climate advisors, in Germany, the United States, and elsewhere, do not understand the problem is starkly illustrated by repetition of goals to reduce CO2 emissions by a percentage (say 40% by 2020, 80% by 2050, or o ...

Hansen v. coal	David Roberts	07 Jan 2008	Gristmill
PRE-PUBLISHING UPDATE: After I wrote this but before I posted it, I got an email from Grist reader CD notifying me of the sad news that Mass.'s gov approved the coal gasification plant. Decisions like this are going to look awfully stupid in a few years. ----- I meant to mention this last week, but better late than never: Kudos to climate scientist James Hansen, not only for being a public advocate against coal, but doing so in a targeted op-ed in the Boston Globe, ...

Parting company with McKibben and, maybe, Hansen What is the safe upper limit for atmospheric CO2?	Joseph Romm	31 Dec 2007	Gristmill
The nation's top climate scientist, NASA's James Hansen, apparently now believes 'the safe upper limit for atmospheric CO2 is no more than 350 ppm,' according to an op-ed by the great environmental writer Bill McKibben. Yet while preindustrial levels were 280, we're now already at more than 380 and rising 2 ppm a year! Like many people, in the 1990s I believed 550 was the target needed to avoid climate catastrophe -- but now it's clear that: 550 ppm would lea ...

Points of no return ahead James Hansen talks about what to do now that we've passed the 'tipping point'	Kit Stolz	14 Dec 2007	Gristmill
For the last few years, James Hansen, the man who first warned Congress of global warming in testimony last century, and the man considered NASA's "top scientist" on climate questions, has been giving talks around the country asking can we avoid dangerous climate change (PDF)? But Hansen has changed his tune: no longer does he ask if we have passed the tipping points of climate change. In a press conference Thursday morning at the American Geophysical Union, h ...

Dear Prime Minister, Dear Chancellor A letter from James Hansen pleads for action on coal-fired power plants	Guest author	09 Dec 2007	Gristmill
The following is a draft letter from noted climate scientist James Hansen to UK Prime Minister Gordon Brown, on the subject of proposed new coal-fired power plants. (A similar letter is in the works to German Chancellor Angela Merkel.) The author would appreciate feedback. ----- Dear Prime Minister Brown, Your leadership is needed on a matter concerning coal-fired power plants in your country, a matter with global ramifications, as I will clarify. For the sake ...

Global warming and the Holocaust Is the analogy between climate change and Hitler's atrocities appropriate?	David Roberts	26 Nov 2007	Gristmill
Andy Revkin has an interesting post on Dot Earth about global warming and Holocaust analogies. On Oct. 22, climate scientist James Hansen testified before the utilities board in his home state of Iowa. He said, among 59 pages of other stuff, this: If we cannot stop the building of more coal-fired power plants, those coal trains will be death trains -- no less gruesome than if they were boxcars headed to crematoria, loaded with uncountable irreplaceab ...

More swiftboating of James Hansen Hansen's response to a claim that he accepted money from George Soros	Joseph Romm	02 Oct 2007	Gristmill
I don't know how NASA's James Hansen keeps up his pace of writing -- or how he puts up with the steady stream of disinformation launched against him. I am not trying to create a cult of personality around him, but I do feel under some obligation to give his writing as much attention as possible -- as I think he has done more than any other scientist to raise awareness on climate change, and deserves our thanks, not slander. 'The latest swift-boating,' Hansen expl ...

Another 'must read' from Hansen 'Long-term' climate sensitivity of 6 degrees C for doubled CO2	Joseph Romm	02 Oct 2007	Gristmill
The nation's top climate scientist is prolific: He has co-authored another important article: "Global Warming: East-West Connections" (PDF). And I'm not just saying that because he cites one of my articles. In fact, we've been having an email exchange and he strongly disagrees with me that it is too late, in a practical sense, to save the Arctic (and hence the polar bear). He believes strong and smart action now could work -- whereas I believe we need ...

A hoax based on a fraud Rush Limbaugh calls climatologist James Hansen a 'double agent'	Kit Stolz	29 Sep 2007	Gristmill
Earlier this week, the notorious Rush Limbaugh got in trouble for calling soldiers in Iraq opposed to the war "phony." Thursday he called the science of ozone depletion "phony" and the science of climate change "fraudulent." Limbaugh went on to accuse Dr. James Hansen, America's top climatologist, of being "dishonest," compared him to a "CIA double agent," and said he should be "drummed out of NASA." Does an ...

Did climate change contribute to the Minneapolis bridge collapse? The question must be asked	Joseph Romm	07 Aug 2007	Gristmill
The thought didn't cross my mind until my Minneapolis-based brother suggested it. I had asked him for his thoughts on the collapse, and that is the question he posed. I was skeptical at first, but after doing a Google search -- and after NBC reported Sunday that National Transportation Safety Board investigators are 'looking at everything' including 'the weather' -- I think it is a legitimate question to ask. First, though, why is it an important question to as ...

Hansen on 'trains of death' Yeah, coal again	Joseph Romm	26 Jul 2007	Gristmill
Still more from James Hansen's email: Ed Wilson explains that the 21st century is a "bottleneck" for species, because of extreme stresses they will experience, most of all from climate change. He foresees a potentially brighter future beyond the fossil fuel era, beyond the peak human population will occur if developing countries follow the path of the developed world to lower fertility rates. Air and water can be clean and we will learn to live wi ...

NASA's Hansen on Live Earth, Gore, and coal It's all about coal	Joseph Romm	25 Jul 2007	Gristmill
More from James Hansen's email: I was invited to go on stage at "Live Earth" at the Meadowlands, between Jon Bon Jovi and Smashing Pumpkins performances. I agreed to this, on the condition that I could bring my grandchildren, Sophie and Connor. I assumed it would be like last year when I appeared with Al Gore before a young audience, with a rather impromptu discussion of global warming. Bad assumption. When I asked "Where's Al?", I was told th ...

More of NASA's James Hansen on Old King Coal How coal CO2 is different from oil CO2	Joseph Romm	24 Jul 2007	Gristmill
Our top climate scientist has sent out a really, really long email (where does he find the time?), mostly discussing comments on his recent essay on coal. I think Hansen is the clearest thinker on climate among the top scientists in the field, so I will reprint the email, breaking it up into several postings. The first one addresses "Coal-CO2 versus Oil-CO2": My statement that releasing a coal-CO2 molecule into the air is more harmful than setting ...

Coal is the enemy of the human race: James Hansen edition A guest essay	David Roberts	12 Jul 2007	Gristmill
A week or so back, climate scientist James Hansen passed this essay along to a few folks. It's about the need to rein in coal, and the puzzling lack of involvement from young people on the issue. I thought I'd pass it along. ----- Scientific data reveal that the Earth is close to dangerous climate change, to tipping points that could produce irreversible effects. Global warming of 0.6�C in the past 30 years has brought the Earth's temperature back to about the ...

Science: Eh, who cares? Hansen says scientists need lovin', too	Kate Sheppard	26 Jun 2007	Gristmill
NASA climate scientist James Hansen has a new paper out, titled 'How Can We Avert Dangerous Climate Change,' which is actually a slightly-edited version of his testimony before Congress in April. The paper is available online here (PDF), and it's worth checking out, of course. But also interesting is the preamble Hansen included in his email announcing the new paper: President Eisenhower was arguably the last United States President to seek and value advice of scien ...

Hansen keeps sounding the alarm Is anyone listening?	David Roberts	19 Jun 2007	Gristmill
James Hansen has a new paper out, co-authored with six other scientists: "Climate Change and trace gases." It appears in the current issue of the Philosophical Transactions of the Royal Society, and Hansen says: "In my opinion, among our papers this one probably does the best job of making clear that the Earth is getting perilously close to climate changes that could run out of our control." Steve Connor has a writeup in The Independent. Sounds l ...

NASA administrator says stupid things Hard to believe he's part of the Bush administration!	David Roberts	31 May 2007	Gristmill
Everybody and their cousin has already posted on this, so I won't spend a lot of time on it, but yesterday on NPR, NASA administrator Michael Griffin said some extraordinarily stupid things. To wit: I'm aware that global warming exists. ... Whether that is a longterm concern or not, I can't say. ... ... I am not sure that it is fair to say that it is a problem we must wrestle with. To assume that it is a problem is to assume that the state of Earth's climate t ...

Yet another must-read by James Hansen On 'scientific reticence' and sea-level rise	Joseph Romm	25 May 2007	Gristmill
Sea level rise of 5 meters in one century? Even if most scientists will not say so publicly, that catastrophe is a real possibility, according to the director of NASA's Goddard Institute Of Space Studies. It may seem like I single Hansen out for recommended reading. But that's only because he: is the nation's top climatologist writes prolifically speaks with unusually bluntness for a scientist has been more right than just about any climat ...

Peak oil and climate change New Hansen paper	John McGrath	22 May 2007	Gristmill
Today the Oil Drum linked to a James Hansen released paper analyzing the impact of peak oil, peak gas, and peak coal on the likely emissions of carbon. Hansen notes that most of our emissions scenarios have thus far failed to account for whether the carbon will even be there to burn. Plenty of graphy goodness, but what I took away was this: There's just enough oil and gas left in the ground to take us up to, or maybe a bit over, the 450 parts per million of CO2 that ...

Clarion Caller An interview with renowned climate scientist James Hansen	Kate Sheppard	15 May 2007	Main Dish
James Hansen. Photo: nasa.gov James Hansen, NASA's top climate expert, believes scientists have an obligation to speak out when their findings have important implications for the public -- and he certainly put that belief into practice last year when he told The New York Times that the Bush administration was trying to muzzle his calls for reducing greenhouse-gas emissions. Hansen has been ...

Inundated with information on sea level rise How high and how fast?	Joseph Romm	30 Mar 2007	Gristmill
How high and fast will sea levels rise? An important piece (PDF) by Stefan Rahmstorf in Science concludes: A rise of over 1 m by 2100 for strong warming scenarios cannot be ruled out, because all that such a rise would require is that the linear relation of the rate of sea-level rise and temperature, which was found to be valid in the 20th century, remains valid in the 21st century. These scenarios, which are really nothing more than business-as-usual emissions plus ...
