IN 1987, CALIFORNIA was at the beginning of what would be a six-year drought – the second driest in the state’s history. Fittingly, that same year Peter Gleick helped to co-found the Pacific Institute, a global think tank that would become a leader in global environmental and California water issues. In 1987, Gleick had just finished a doctorate from the University of California, Berkeley, in the Energy & Resources Group, where his dissertation was the first to study the impact of climate change on water resources.
