Global Warming Meets Global Data by John R. Christy 14 September 2001 The issue of whether humans are having an impact on climate has been given considerable attention in the past few years. Most people think of human attribution when they hear the phrase "global warming". We shall examine the scientific information available now regarding this problem, including the results from microwave radiometers on polar-orbiting spacecraft which show little temperature change at all in the past 22+ years. This contradictory evidence regarding global warming will be presented as will other aspects of the climate change idea. Because there are policy implications (e.g. heavy taxation, or rationing of energy) for dealing with possible causes of a potential change in climate, the issue has found its way to the White House and Capitol Hill. Christy partnered with Dr. Roy Spencer (UAH, formerly of NASA) to produce the satellite temperature record. He has also testified before several House and Senate Committees, served on National Academy Panels and was selected as a Lead Author for the United Nation's Intergovernmental Panel on Climate Change 2001 Report on the science of climate.
