Our guest this episode is author, environmentalist and activist Bill McKibben, whose 1989 book The End of Nature is regarded as the first book for a general audience about climate change. He is also a founder of 350.org, the first planet-wide, grassroots climate change movement, which has organized 20,000 rallies around the world. A former staff writer for The New Yorker, McKibben writes frequently for a variety of publications around the world, including The New York Review of Books, National Geographic and Rolling Stone. He is the author of more than a dozen books; his latest, published in April, is Falter: Has the Human Game Begun to Play Itself Out?

McKibben joined John Merino for an in-studio conversation shortly after he delivered his Aug. 15 lecture in the Chautauqua Amphitheater as part of a week themed “Shifting Global Power.”
