That's why she didn't think to ask her husband what he thought about the issue before they got married.
"It was about six months after we got married that we realized that we are not on the same wave length here," she recalled. Lengthy debates ensued between Hayhoe the scientist and her husband, evangelical Christian pastor Andrew Farley.
"So it was the most tremendous learning experience to talk with someone who I know shared my faith and my beliefs, who I knew was really smart and really educated to talk through why is it that we do or we don't think this thing is real," said Hayhoe.
Farley eventually changed his views on climate change and together they wrote the book "A Climate for Change, Global Warming Facts for Faith-Based Decisions."
