Fighting climate change as an evangelical Christian Dr. Hayhoe is an Atmospheric Scientist whose research focuses on understanding the impacts of climate change on people and the planet. She doesn't accept global warming on faith: she crunches the data, analyzes the models and helps Engineers, City Managers and Ecologists quantify the impacts. Katharine doesn't let politics get in her way, but uses a scientific approach to address climate change rather than using a faith based approach that counts on God solving the climate crisis, or even denying it in the first place.
