Abstract
In the 1980's and 90's, considerable emphasis has been placed upon climate and environmental issues in the United States. Much air pollution legislation has been put into force. Long-range climate trends have been observed and predicted. Dire scenarios of dramatic warming with attendant droughts and coastal flooding have been predicted. At the same time, devastating displacements of population centers and agricultural consequences due to a possible new "Ice Age" have been presented to the public by other experts.
