Cox Title: Introduction: Facts and Uncertainties Classification-JEL: F0 Pages: 1-8 Volume: Volume 12 Issue: Number 1 Year: 1991 Abstract: The unusually hot summer and drought in 1988 in parts of North America stimulated wide discussions about the cause of these events. While most scientists now studying climate believe that the 1988 events were shortrun phenomenon, some scientists and many policy makers in the U.S. Congress and Administration suggest that this weather was linked to global warming caused by a build-up of the so-called greenhouse gases: carbon dioxide, nitrogen oxides, methane and chlorofluorocarbons.
