The Primary Cause Of Climate Change

"New evidence found by teams of climate researchers leaves no doubt that industrial emissions of greenhouse gases are responsible for increasing global temperatures -- an ominous trend that has speeded up in the past 50 years and threatens to continue for centuries, according to a report by two of the nation's leading atmospheric scientists...Thomas Karl, a meteorologist at the National Climatic Data Center in Asheville, N.C., and Kevin Trenberth, chief of the climate analysis section at the National Center for Atmospheric Research in Boulder, Colo., are publishing their analysis in Friday's edition of the journal Science.Neither scientist criticized the Bush administration's refusal to ratify the Kyoto treaty, which is designed to regulate emissions of heat-trapping greenhouse gases worldwide. But their published comments reflected the growing concerns of most climate experts over the White House stance."
