Andrew Revkin is one of America's most honoured and experienced environmental journalists and the founding director of the new Initiative on Communication and Sustainability at Columbia University's Earth Institute. He's written on climate change for more than 35 years, reporting from the North Pole to the White House, the Amazon rain forest to the Vatican - mostly for The New York Times. He has held positions at National Geographic and Discover Magazine. He's written books on the dawn of Earth's Anthropocene age, the history of humanity's relationship with weather and climate, the changing Arctic, global warming and the assault on the Amazon rain forest. His work has been turned into film including the triple-Golden-Globe-winning HBO film "The Burning Season,". This week's podcast covers what Andy learned living on a boat, thoughts on nuclear energy, how views have changed on the environment and climate change, and much more.
