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 (https://en.wikipedia.org/wiki/350.org) and Third Act. He has authored a dozen books about the environment, including his first, The End of Nature (https://en.wikipedia.org/wiki/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.
