Dr. Katharine Hayhoe is a climate scientist who leads the Climate Science Center at Texas Tech University and is the host and producer of the PBS series Global Weirding. I asked her everything you want to know about climate change but were afraid to ask. Hayhoe has a positive, upbeat manner that leaves listeners feeling as if she’s talking about planning the best birthday party ever rather than warning about climate change. Perhaps that is her appeal. She has earned a reputation—she’s been named to Time’s 100 most influential people list and Fortune added her to their World’s Greatest Leaders list—for being able to communicate climate science better than most. She explained why a difference as small as two degrees actually matters, why she calls it global weirding, how she explains climate science to skeptics who are religious, and the respective roles of big business, entrepreneurs and individuals in fighting climate science. Customarily, I think it is my role as a Forbes contributor to distill a source’s insights into digestible bites for my readers. Hayhoe is such an effective communicator that I’ve instead chosen to provide you with a lightly edited transcription of most of our conversation (I still hope you’ll watch or listen to the full interview.)
