(Editor's Note: This file presents news and information from the Copenhagen climate change conference on Dec. 10, distilled from news outlet reports. Check for updates during the day.)

<Update>: At Copenhagen, the simplest idea for corraling climate change is this: don't cut the trees. Logging in tropical forests releases 1.6 billion tons of C02 each year. When it's in the ground, it's not in the atmosphere. Same principle for old growth forests in the northwest United States and in the Tongass National Forest.

<Update>: Here's an interesting take by the Washington Post on the EPA's announcement that greenhouse gases can be regulated. Says the Post: "The threat of the EPA regulating in Congress's stead should persuade lawmakers to look at climate-change afresh." The announcement was made as the Copenhagen conference opened Monday.

<Update>: The world's two biggest greenhouse gas emitters - China and the U.S. - squabbled in Copenhagen today over who is responsible and who should pay. Here's the latest on this story.

The Los Angeles Times reports that Interior Sec. Ken Salazar is leading a "charm offensive" in Copenhagen to sell world government and business leaders on the United States' increased commitment to renewable energy and combating climate change. Not charmed are Alaskan Natives who protested in Copenhagen over Salazar's approval of drilling by Shell Oil in the Chukchi Sea.

In Copenhagen it's all about the money—and there's not enough of it being proposed by rich nations to help poor nations deal with impacts of climate change, says American billionaire George Soros. He's got an idea.
