U.S. GHG emissions are about 17 percent of global emissions. If we apply the widely accepted MAGICC climate model developed at the National Center for Atmospheric Research, and if we assume the international Intergovernmental Panel on Climate Change midrange emissions path, an immediate cut in U.S. emissions by half would yield a reduction in global temperatures of 0.1 degrees Celsius 100 years from now.
