For eight years, America's attitude towards international action against climate change was the less the better, with Bush famously abandoning the Kyoto Protocol early in his presidency and spurning all efforts later to cut emissions worldwide. But with President Obama talking up a more active approach to combating climate change and putting his money where his mouth is in his budget, which includes a cap and trade program, environmentalists are growing excited about the possibility of a new global effort to reduce emissions. According to The New York Times, Obama's chief negotiator on climate change aims to have a treaty ready to sign in Copenhagen in December. “The No. 1 thing will be for everyone to see that the U.S. is on an urgent and transformational path to a low carbon economy — that would have a galvanizing effect,” John Ashton, Britain's special representative for climate change, told the Times.
