Climate change has been a hard sell among some communities of faith. Katharine Hayhoe is a Climate Scientist and an Evangelical Christian. She has spent years trying to convince other Christians that climate change is real. She told NPR that "the people we trust, the people we respect, the people whose values we share, in the conservative community, in the Christian community, those people are telling us, many of them, that this isn't a real problem - that it's a hoax. Even worse, that you can't be a Christian and think that climate change is real. You can't be a conservative and agree with the science." Hayhoe says that caring about climate change is one of the most Christian things you can do.
