UN Panel's Global Warming Report May Win U.S. Support

American officials are planning to back a new United Nations document that says governments and businesses will have to spend billions of dollars a year to reduce global warming and adapt to its effects.

The report will be discussed this week at a meeting of the United Nations Intergovernmental Panel on Climate Change, or IPCC, the group of scientists producing the most detailed study yet of global warming. The group's recommendation will guide talks in Bali, Indonesia next month of the UN body charged with writing a successor to the Kyoto Protocol, an international accord that set carbon gas emission limits for some countries.

By agreeing with the draft document, a copy of which was obtained by Bloomberg, the U.S. is indicating a need for faster action to slow climate change. As the largest emitter of gases blamed for global warming, the U.S. is seen by other nations as critical to the creation of a new worldwide response when the Kyoto agreement expires in 2012.
