Career Gleick received a B.S. from Yale University and an M.S. and Ph.D. in Energy and Resources from the University of California, Berkeley, with a focus on hydroclimatology. His dissertation was the first to model the regional impact of climate change on water resources. Gleick produced some of the earliest work on the links between environmental issues, especially water and climate change, and international security, identifying a long history of conflicts over water resources and the use of water as both a weapon and target of war. He also pioneered the concepts of the soft water path, and peak water. Gleick worked as the Deputy Assistant for Energy and the Environment to the Governor of California from 1980 to 1982. In 2003, he was awarded a MacArthur Fellowship for his work on water resources, and in 2006 he was elected to the U.S. National Academy of Sciences.
