"President Barack Obama says the United States and China are looking for a comprehensive deal during next month's climate change summit that will 'rally the world.'"

"President Obama and other world leaders have decided to put off the difficult task of reaching a climate change agreement at a global climate conference scheduled for next month, agreeing instead to make it the mission of the Copenhagen conference to reach a less specific 'politically binding' agreement that would punt the most difficult issues into the future."

"At little noticed talks last week in Port Ghalib, Egypt, climate advocates were hoping to seal a global agreement for the phase down of super greenhouse gases and give next month's Copenhagen climate talks a can-do running start. But the annual meeting of the 198 nations of the Montreal Protocol began on a note of contention that five days of discussions could not overcome."

"Less than a month before negotiators will meet in Copenhagen with the lofty goal of crafting a deal to curb global greenhouse gas emissions, the Obama administration is considering endorsing a limited short-term climate pact and deferring more ambitious action until next year."

"Scientists sifting for trends in record high and low temperatures across the United States have found  more evidence of long-term warming of the climate, with the biggest shift coming through a reduction in record low nighttime temperatures."

"In the new economy created by global warming, forests are turning into a valuable commodity. Promising not to cut them down is one of the most popular ways companies would like to offset their emissions. Correspondent Mark Schapiro follows the trail of one of those offset projects deep into Brazil's Atlantic forest."

"With the clock ticking on the high-stakes Copenhagen climate summit, US President Barack Obama will try to salvage fading hopes for a deal as he meets this month with the leaders of China and India."

"As the world heads for tough negotiations over a global climate deal next month, an influential forecasting agency said on Tuesday that current energy policies were not sustainable, and that a vast transformation of energy use was required to fend off the worst consequences of global warming."

"The Senate climate debate shifts into a higher gear this week as advocates look beyond the partisan gridlock that engulfed the Environment and Public Works Committee and onto the broader quest of finding 60 votes for floor passage."

"This is the consequence of failure at Copenhagen: A marked shift in scientific effort from solving global warming to adapting to its consequences, a hodge-podge of uncoordinated local efforts to trim emissions – none of which deliver the necessary cuts – and an altered climate."

"The US has given up hope of reaching a global climate change treaty at Copenhagen and is working towards a deal late next year, the Obama administration said today. The decision ends hopes of a legally binding deal being sealed next month."
