Soot pollution a big contributor to climate change, study finds

Soot pollution contributes significantly to climate change and is second only to carbon dioxide as a climate-warming factor, according to a new study published in the journal Nature Geoscience. The study estimates that the Intergovernmental Panel on Climate Change may have underestimated soot’s role as a climate-warming factor by about three or four times. If […]

For fossil fuel fans, bleak is the new black

The U.S. Chamber of Commerce is on a barnstorming tour, holding a series of innocuously-named "State Climate Dialogues." While the promotional materials sound forward-looking -- conservation, clean energy, efficient technology -- make no mistake about the purpose of the events. The national chamber is trying to derail the Lieberman-Warner Climate Security Act or any other legislation that puts a price on greenhouse-gas emissions.

How's the tour being received so far? Not so well:

Claims of dramatic job losses and rising prices for consumers were quickly dismissed by environmentalists, Gov. Brian Schweitzer's office, Montana economists, and others. Those forecasts fail to account for new technology and emerging economies that will reduce carbon emissions and keep Montana's economy humming.

"It's fake and it's not realistic," Eric Stern, senior counselor to Gov. Brian Schweitzer, said of the industry forecast. "There is a clean-energy future, and Montana sits at the center of that."

...

In the audience, former Billings Mayor Chuck Tooley, who began offering public presentations on climate change and the need for action two years ago, said he was taken aback.

"He's from upside-down land," Tooley said of ["Frontiers of Freedom" President George] Landrith. "I wasn't sure if he was serious or not."

As oil prices top $109 a barrel, it's quite an odd time to make the case that climate action will destroy our economy:

Does refuting deniers only strengthen and empower them?

Science journalist Chris Mooney, author of must-read The Republican War on Science, has a post at Science Progress titled "Enablers: Sometimes refuting unscientific nonsense reinforces it." This is a provocative and timely post, given the recent tussles I've been having with deniers and delayers.

I've talked to Chris, and his occasional co-blogger Matthew Nisbet (who has a related post here) many times. And while we are probably 95 percent in agreement on most things climate, I don't quite buy their argument here:

So we've reached a point where we may well be wasting our energies if we continue to battle climate skeptics. Indeed, we run the risk of propping them up far more than they deserve.

For that's the other problem with constantly rebutting anti-science forces -- not only does it waste our time, but it may play right into their hands. Consider: Over at his blog, Framing Science, Matthew Nisbet makes a very strong case that the rhetorical strategy of the Heartland Institute is exceedingly similar to that of the anti-evolutionist think tank the Discovery Institute. If so, it follows that the defenders of climate science ought to be at least as leery of outright engagement with Heartland as the defenders of evolutionary science are when it comes to engaging with Discovery.

The reason is that if you actually bother to rebut the Heartlands and Discoverys of the world, you instantly enter into a discourse on their own terms. The strategic framing these groups employ to attack mainstream science heavily features the rhetoric of scientific uncertainty ...

The magic mouse of Guy Caruso

Want to kill one coal plant? Use a lawyer.

Want to kill a hundred? Use a spreadsheet.

On March 4, without fanfare, a bureaucrat named Guy Caruso caused 132 coal plants to disappear with a wave of his magic mouse.

Report by Australia economist suggests ambitious climate policy

An interim report on the economic impact of climate change on Australia — Oz’s version of the Stern Review — has been produced by economics professor Ross Garnaut. The government-commissioned Garnaut Review, which will be published in full in September, points out that Australia’s dry climate, heavy reliance on agriculture, and tight trade relationships with […]

Australia’s pivotal Garnaut climate report to back 100 percent permit auctions

The bar for national climate policy just inched up again. In April of last year Australia’s State and Territory Governments commissioned a comprehensive independent study from economics professor Ross Garnaut. The Garnaut Climate Change Review is meant to be Australia’s version of the U.K.’s influential Stern Review: it will examine the economic impacts of climate […]

Arctic ice alarmingly scarce, say NOAA, NASA, NSIDC

Yes, I know you've all heard that we've had "record" refreezing of Arctic ice. Big shock there. We had record melting followed by a temporary cooling La Niña event. What those denier/delayer-1000 talking points don't tell you is that the refrozen ice is very thin and still at record low levels following the staggering ice loss this summer.

To set the record straight, on Wednesday, the National Snow and Ice Data Center and NASA had a teleconference to show the surprising and alarming new data from NASA's ICESat satellite, which revealed over the past year "the steepest yearly decline in perennial [i.e., old, thick] ice on record" (click to enlarge):

One can be anti-nuclear subsidy without being “anti-nuclear.”

Messing with nature more won’t fix the messes we’ve already made

This post is by ClimateProgress guest blogger Bill Becker, executive director of the Presidential Climate Action Project.

[JR: Geo-engineering is to mitigation as chemotherapy is to diet & exercise. You can find some more specific reasons geo-engineering is unlikely to make sense at these posts: "Geo-engineering remains a bad idea" and "Geo-engineering is not the answer." I will be blogging again on this shortly. In the absence of strong mitigation efforts, geo-engineering will not stop catastrophic outcomes, like the end of most ocean life.]

Time magazine has declared geo-engineering one of "10 ideas that are changing the world."

"Messing with nature caused global warming," Time wrote. "Messing with it more might fix it."

Early-springing spring is a climatic consequence

You may have gone to bed last night in one season and woken up in another, as spring officially began at 1:48 a.m. EDT Thursday. (Yes, apparently “they” know the exact time.) We kind of feel like its about damn time the sun came out, but in fact trees are blossoming and birds are singing […]
