From the preface: "The extent, magnitude and impacts of the drought of 1988 in the United States and Canada were recently discussed at a seminar jointly organized by the National Climate Program Office (NCPO), Resources for the Future (RFF) and the Board of Atmospheric Sciences (BASC) of the National Academy of Sciences (NAS). Information presented in this proceedings was drawn primarily from the seminar. Additional background material was provided by federal agencies, especially the Climate Analysis Center (CAC), the National Climate Data Center (NCDC) of NOAA, Regional Climate Centers (RCC), the Atmospheric Environmental Service (AES) of Canada, and the Congressional Research Service. [...] This proceedings focuses on the climatology of the drought over the North American continent, its historic context, and its relationship to global climate warming. The RCC's provided specific case studies of impacts at regional levels. A summary of Congressional actions related to the drought is also given."
