Thousands Negotiate New Climate Treaty | LiveScience

Description

Scientists studying the changing nature of the Earth's climate say they have completed one crucial task — proving beyond a doubt that global warming is real.

Now they have to figure out just what to do about it.

"It is critical for us to get a much better understanding of the impact of climate change in some parts of the world," Rajendra Pachauri, chairman of the U.N.'s Intergovernmental Panel on Climate Change, told The Associated Press in an interview Tuesday.

Scientific warnings of potential catastrophe have been the backdrop for talks among more than 10,000 delegates and environmentalists negotiating a treaty to control the emission of greenhouse gases, which have grown by 70 percent since 1970. The treaty, due to be completed in one year, would replace the Kyoto Protocol, which expires in 2012.
