Katharine Hayhoe’s influence on conversations about climate change is known to many through her vibrant and engaging social media presence. As a distinguished professor at Texas Tech University and the author of the recently published Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World, she uses her platform to educate and to inform. Katharine speaks openly as a deeply committed Christian about how she is called to be a scientist, using her work to shed light on the ways climate change affects the most vulnerable. Even in the face of crisis, she invites everyone to see that hope is not the same as optimism or wishful thinking; it is a practice that can encourage individuals to act and address pressing issues, including this one. She suggests that we are being called to care for each other and our world.
