Michael MacCracken received his B.S. in Engineering degree from Princeton University in 1964 and his Ph.D. degree in Applied Science from the University of California Davis/Livermore in 1968. His dissertation used a 2-D climate model to evaluate the plausibility of several hypotheses of the causes of ice ages. Following his graduate work, MacCracken joined the Physics Department of the University of California’s Lawrence Livermore National Laboratory (LLNL) as an atmospheric physicist. His research in the ensuing 25 years included numerical modeling of various causes of climate change (including study of the potential climatic effects of greenhouse gases, volcanic aerosols, land-cover change, and nuclear war) and of factors affecting air quality (including photochemical pollution in the San Francisco Bay Area and sulfate air pollution in the northeastern United States).

From 1993-2002, MacCracken was on assignment as senior global change scientist to the interagency Office of the U.S. Global Change Research Program (USGCRP) in Washington D.C. From 1997-2001, he was executive director of the USGCRP’s coordination office for the US National Assessment. He also coordinated the official U.S. Government reviews of several of the assessment reports prepared by the Intergovernmental Panel on Climate Change (IPCC), and has been a co-author/contributing author of various chapters in some of the reports. MacCracken retired on September 30, 2002 from LLNL, and is currently engaged in several part-time tasks, including serving on the integration team for the Arctic Climate Impact Assessment. As president of IAMAS, MacCracken served on the Executive Committee of International Union of Geodesy and Geophysics (IUGG). MacCracken is a fellow of the American Association for the Advancement of Science (AAAS) and a member of the American Meteorological Society, the Oceanography Society, and the American Geophysical Union, for which he is currently serving as Vice-Chair of their Focus Group on Global Environmental Change.
