Climate Change

"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.'"

"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."

"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."

"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."

"A coalition of conservation groups are calling on international climate negotiators in Copenhagen next month to develop land-use policy incentives intended to encourage governments to protect natural carbon storehouses -- especially those in northern boreal forests and peatlands found in Canada, Scandinavia and Russia."

"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."

"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."
