On the latest episode of Bernie: The Podcast I speak to environmentalist Bill McKibben. Bill is an activist and writer who is one of the leading voices on the impact of climate change and a dear friend of mine. He is the founder of the climate campaign group 350.org and Third Act. He has authored a dozen books about the environment, including his first, The End of Nature (1989. We discuss the record heatwaves sweeping the globe as we speak, the growth of renewable energy and how much time we have to save our planet, and what a second Trump term would mean for climate change.
