GM is planning to keep drivers and passengers of 2013 Chevrolet, Buick, GMC, and Cadillac cars cool with a sustainable air-conditioning refrigerant that lingers in the atmosphere for only days instead of years.

Honeywell has designed a new refrigerant, (HFO-1234yf), that lingers in the atmosphere for just 11 days and has a global warming potential (GWP) of only 4, a 99.7 percent improvement over current emissions.

On average, the refrigerant used in current GM models, R-134a, has an atmospheric life of more than 13 years and a GWP of more than 1,400.

The U.K. government on Thursday launched a Google Earth layer that models what Earth might look like in the event of a significant worldwide rise in temperature.

Specifically, the interactive map visually demonstrates what could happen if carbon emissions are not curbed, and as a result, Earth's temperature rises four degrees Celsius above the pre-industrial worldwide climate average. As a plethora of scientists and politicians have repeatedly stated, an increase in things like drought and agricultural disruption as a result of drought, could lead to instability and violence in some parts of the world.

WASHINGTON--Sen. John Kerry (D-Mass.) and Sen. Joseph Lieberman (I-Conn.) are scheduled to formally unveil on Wednesday a compromise U.S. climate change bill they want passed this year.

Besides bringing down emissions of carbon dioxide and other gases blamed for global warming, it would expand offshore oil drilling and nuclear-power production in a move to appeal to a broader number of senators.

Here are highlights of the bill, called the "American Power Act," according to a summary of the legislation being circulated to senators and obtained by Reuters:

Carbon emissions reductions By 2020, carbon pollution would be cut … Read more

LONDON--An inquiry cleared British climate researchers of wrongdoing on Wednesday after their e-mails were hacked, leaked, and held up by skeptics as evidence they had exaggerated the case for manmade global warming.

Former government adviser Ronald Oxburgh, who chaired the panel, said he had found no evidence of scientific malpractice or attempts to distort the facts to support the mainstream view that manmade carbon dioxide emissions contribute to rising temperatures.

The affair stoked the global debate on climate change and put pressure on scientists and politicians to defend the case for spending trillions of dollars to cut emissions and help … Read more

Senator John Kerry said a bipartisan climate change bill would emerge soon in the U.S. Senate, contradicting what he called the "conventional wisdom" that the legislation was dead this election year.

Kerry is working closely with the Obama administration and a bipartisan group of senators on a comprehensive bill to reduce U.S. carbon dioxide pollution blamed for global warming.

"We're on a short track here in terms of piecing together legislation we intend to roll out," Kerry told a climate policy forum, without giving details of his proposals.

The U.S. Senate is unlikely to pass a comprehensive climate change bill to reduce greenhouse gas emissions this year, according to a Reuters survey of 12 key Democrat and Republican Senators who could hold the swing votes.

While the Obama administration and a bipartisan core of senators still hope there is life for a climate change bill that would put a price on carbon emissions and help reinvigorate ailing international talks, the senators interviewed by Reuters this week were much more pessimistic.

The survey underscores that global warming--a scientific finding still hotly disputed by many Americans--could end up being … Read more

The White House has dropped projected revenue from a "cap-and-trade" mechanism to fight climate change from its new budget, an administration official said, bowing to the possibility that the Congress may not pass it.

Last year, the Obama administration forecast revenue of $646 billion in the years 2012-2019 from an emissions trading program that formed the crux of its proposal to fight global warming.

The legislation that contains that proposal is now stalled in the Senate, and cap-and-trade--which sets limits on greenhouse gas emissions and allows companies to trade permits to pollute--may be cut from a final bill … Read more

DAVOS, Switzerland--So far, wind turbines are not Sputnik. But one day they could be.

The global race to develop clean technology is not just about who can build the best solar parks or wind farms. It is also shaping up as a contest between Chinese-style capitalism and the more market-oriented approach fancied by the United States and Europe.

The question comes down to this: will China's highly capitalized command-and-control economy trump laissez-faire in a low-carbon shift that is widely portrayed as the next industrial revolution?

The failure in Copenhagen to agree to replace the Kyoto Protocol with a new global climate treaty when it expires in 2012 has thrown the focus on national measures. And by almost all accounts, the Chinese are coming on strong.

Beijing's top leaders have made clear their intention to have their nation dominate this new industry, up and down the value ladder. And in their quest for the prize, they are not burdened by concerns facing their Western counterparts--such as the impact of wind turbines on landscapes, higher energy prices for consumers, or investor returns.

President Barack Obama said on Wednesday that disappointment over the outcome of the Copenhagen climate change summit was justified, hardening a widespread verdict that the conference had been a failure.

"I think that people are justified in being disappointed about the outcome in Copenhagen," he said in an interview with PBS Newshour.

"What I said was essentially that rather than see a complete collapse in Copenhagen, in which nothing at all got done and would have been a huge backward step, at least we kind of held ground and there wasn't too much backsliding from where … Read more
