Katharine Hayhoe is an atmospheric scientist whose research focuses on understanding the impacts of climate change on people and the planet. She is the Chief Scientist for The Nature Conservancy and a Distinguished Professor at Texas Tech University.

Hayhoe believes that the most important thing each person can do about climate change is to talk about it. In her book, “Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World,” her newsletter Talking Climate, and her TED talk, she explains how.

She has authored four U.S. National Climate Assessments and been named one of TIME's 100 Most Influential People and a member of the American Academy of Arts & Sciences. Hayhoe is also a United Nations Champion of the Environment, the World Evangelical Alliance’s Climate Ambassador, and has received Climate One’s Stephen H. Schneider Award for Outstanding Climate Science Communication.
