WASHINGTON -- Starting Monday, negotiators in Copenhagen will try to nail down all of the main elements of a treaty to curb global warming, but a final agreement won't be possible until the United States figures out what it is willing to do to reduce emissions of heat-trapping pollution.
President Barack Obama plans to visit the talks on their final day to promise that the United States will cut its share of emissions and to press for a strong agreement. The world, however, will be watching to see whether he also signals a willingness to pressure Congress to enact the law that's needed to make that happen.
Despite charges by some critics that data on global temperatures have been altered, the evidence of climate change is conclusive and worsening.
