...That's a marked departure from the Bush Administration, which sought to marginalize global diplomacy on carbon emissions. With a major U.N. summit on global warming just 10 months away in Copenhagen, the current shift is necessary if the U.S. is to regain leadership on climate issues and work toward an equitable international deal on reducing carbon emissions. "The U.S. is the only nation that can lead the world, and this is the most serious challenge the world has faced," said Gore...
...most of his prepared testimony, Gore ran through an abbreviated version of his famous Inconvenient Truth PowerPoint presentation on the threat of climate change - updated with new, increasingly scary data. He pointed out that the increase in global carbon emissions over the past few years is well above previous estimates from the U.N.'s Intergovernmental Panel on Climate Change, meaning that we are beginning to put ourselves on track for worst-case scenarios. He noted a sobering new paper published Jan. 27 in the Proceedings of the National Academy of Sciences, which indicated that even if we managed to stabilize...
...greens, that denial was a sign of just how intransigent the Bush Administration had become on global warming. Not only would the Bush EPA refuse to take action on its own to slow the growth in carbon emissions, it would actively prevent states - even ones with Republican governors - from taking steps on their own. Now, with Obama directing his EPA to reconsider the waiver - and new EPA head Lisa Jackson has said that she would "very, very aggressively" review the request - the door is open to California once again taking the lead on cleaner cars. "It's a tremendously important...
...that the layer of haze - which many have blamed for the world's increasingly extreme weather patterns - makes rain both more rare during the dry season and more intense during monsoons. And in South Asia, the cloud's net effect on climate change, says the study, rivals that of carbon dioxide...
...silver lining of this massive brown cloud is that a boost in those technologies could decrease soot emissions - fast. "We can't fix every environmental problem, but we can make a huge and immediate change by reducing black carbon," says Veerabhadran Ramanathan, Director of the Center for Clouds, Chemistry & Climate at the University of California at San Diego. (Black carbon manifests as soot particles that comprise brown clouds.) While carbon dioxide levels in the atmosphere respond on a sluggish 100-year timescale to reductions in emissions, soot particles, whose effects are equivalent to roughly half the warming damage that carbon...
