Climate Deal

“The prospects of a global deal on climate change were raised dramatically on Friday night when Barack Obama, US president, said he would attend the final negotiating stages of the Copenhagen summit, which begin next week. All of the world’s big economies, including leading developing nations such as China and India, have now set objectives for curbing their greenhouse gas emissions. This fact was believed to be instrumental in persuading Mr. Obama he needed to be present at the end of the talks.”
