Katharine Hayhoe is an atmospheric scientist who studies climate change, one of the most pressing issues facing the planet today. An expert reviewer for the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change, her life’s work has been dedicated to discovering and communicating the realities of a changing climate to those who will be affected most by it.

As an associate professor in the Department of Political Science and director of the Climate Science Center at Texas Tech University, part of the Department of Interior's South-Central Climate Science Center, Katharine develops new ways to quantify the potential impacts of human activities at the regional scale. As founder and CEO of ATMOS Research, she also bridges the gap between scientists and stakeholders to provide relevant, state-of-the-art information on how climate change will affect our lives to a broad range of non-profit, industry and government clients.

Katharine's work has resulted in over 50 peer-reviewed publications and many key reports including the U.S. Global Change Research Program's 2009 report, “Global Climate Change Impacts in the United States”; the U.S. National Academy of Science 2011 report, “Climate Stabilization Targets: Emissions, Concentrations, and Impacts over Decades to Millennia”; and the upcoming 2013 U.S. National Climate Assessment. In addition to these reports, she has led climate impact assessments for a broad cross-section of cities and regions, from Chicago to California and the U.S. Northeast. The findings of these studies have been presented before Congress, highlighted in briefings to state and federal agencies, and featured in over 200 news and media outlets around the world.

Katharine is currently writing a guidebook and creating accompanying videos on how to incorporate climate projections into impact assessments for the U.S. Fish & Wildlife. Together with her husband Andrew Farley, author, professor and lead teaching pastor of Ecclesia, to write “A Climate for Change: Global Warming Facts for Faith-Based Decisions”, a book that untangles the complex science and tackles many long-held misconceptions about global warming. Her work as a climate change evangelist has been featured in the PBS documentary series, The Secret Life of Scientists and in articles including True Believer that appeared in On Earth magazine in 2012 and Spreading the global warming gospel that appeared in the LA Times in 2011. In 2012 she was named one of Christianity Today's 50 Women to Watch.

Katharine has a B.Sc. in physics and astronomy from the University of Toronto and an M.S. and Ph.D. in atmospheric science from the University of Illinois.
