President Bush has re-entered the global warming debate by unveiling his alternative to the 1997 Kyoto agreement on global warming. His plan offers incentives to businesses to voluntarily reduce U.S. greenhouse gas emissions by an estimated 4.5 percent over 10 years and to reduce power plant emissions.

Bush's plan is dramatically lower than the estimated 33 percent mandatory reduction sought by the Kyoto agreement for the United States, the world's largest producer of greenhouse gas emissions.

Asian and European nations have strongly criticized Bush's decision in 2001 to abandon the Kyoto treaty, which commits 37 industrialized nations to cut gas emissions. Bush has criticized the treaty, saying it set unrealistic goals and could damage the U.S. economy. But other nations worry about scientific concerns that climate change could lead to severe floods and droughts, rising sea levels and an increase in malaria and respiratory disease.
