What has been the global economic trend from 1980 to 2002?
The realities of global warming are hotly debated in many scientific circles. Some scientists insist that statistics show the warming trend had stopped and temperatures had returned to normal by 2002. Others insist the worldwide warming trend continues to this day. Available data seems to indicate that if there is a global warming trend, the overall rise in temperature will be no more than 2 or 3 degrees F, and possibly much less.
