Dr. Katharine Hayhoe
Hayhoe, a climate scientist and Evangelical Christian, is a professor in the Texas Tech Department of Political Science, and runs day-to-day activities of the university’s Climate Science Center, part of the Department of Interior’s South-Central Climate Science Center. Her research focuses on establishing a scientific basis for assessing the regional to local-scale impacts of climate change on human systems and the natural environment. She is founder and CEO of ATMOS Research, which bridges the gap between scientists and stakeholders to provide relevant, state-of-the-art information on how climate change will affect lives to a broad range of non-profit, industry and government clients. With her husband, pastor Andrew Farley, she wrote A Climate for Change: Global Warming Facts for Faith-Based Decisions, a book that breaks down the complex science and tackles many long-held misconceptions about global warming. Together with local PBS station, KTTZ, Hayhoe writes and produces a popular PBS short series, Global Weirding: Climate, Politics and Religion. She serves on the Executive Summary Committee of, and is a convening and lead author for several chapters in, the U.S. Global Change Research Program’s Fourth National Climate Assessment. The second volume is scheduled for release in November 2018. In 2017 Hayhoe was named one of FORTUNE magazine’s world’s greatest leaders, and in 2018 she was awarded the eighth Stephen H. Schneider Award for Outstanding Climate Science Communication.
