Katharine Hayhoe is a highly-respected expert on 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 a professor in the Department of Geosciences at Texas Tech University, 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 40 peer-reviewed publications and many key reports. From 2008 to 2009, she served as a lead author on the federal report, “Global Climate Change Impacts in the United States,” a report commissioned by the Bush administration and released under the Obama administration. This report provides the most up-to-date assessment of how climate change is already affecting, and will continue to impact, our public health, water resources, energy, agriculture and the natural environment. In addition to this report, she has led climate impact assessments for a broad cross-section of cities and regions, from Chicago to California. 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 serving as a lead author on an upcoming National Academy of Sciences report, "Stabilization Targets for Greenhouse Gas Concentrations." Most recently, she teamed up with Andrew Farley, noted 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.
