Despite her identity as an evangelical, climate scientist Katharine Hayhoe doesn't accept global warming on faith; she crunches the data, analyzes the models, and helps engineers, city managers and ecologists quantify the impacts. In her new book, Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World, Hayhoe argues that when it comes to changing hearts and minds, facts are only one part of the equation.  “The biggest problem we have is not the people who willfully decide to reject 200 years of basic science,” she says. “The bigger problem is the number of people who say, ‘it's real’ but they don’t think it matters to them.” Hayhoe says we need to find shared values with others to drive conversations and collective action on climate disruption.
