In her 2009 book, co-authored with husband Andrew Farley, Climate for Change: Global Warming Facts for Faith-Based Decisions, Katharine Hayhoe wrote: “Most Christians are not scientists, and it’s hard to say how many scientists are Christians. In our family, we are both.” The Texas Tech atmospheric physicist, who’s also an Evangelical Christian, has long been one of the most vocal evangelists for the environment. Hayhoe has been featured in the James Cameron-produced TV series Years of Living Dangerously and once nominated as one of the most influential people in the world by TIME. She talks to WIRED about president Trump, clean energy, and, of course, climate change.
