Did you know our world has ended five times? It has been broiled, frozen, poison-gassed, smothered, and pelted by asteroids. And in each of these catastrophic occurrences, climate change has been the culprit.

You may be wondering, how do asteroids have anything to do with climate change? We will leave the details to our guest this week, but essentially there is a triggering event (asteroid, volcano, humans) that causes the oceans to become more acidic and very soon after the entire world dies. This is what happens every time...and it may be happening again.

This week on the show we interview award-winning science journalist Peter Brannen about his new book, The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth's Past Mass Extinctions. In his book and in this interview, Peter takes us on a tour of the 5 ways that the Earth has died, as well as what may be to come. Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave and casts our future in a completely new light.

Peter Brannen is an award-winning science journalist whose work has appeared in the New York Times, The Atlantic, Wired, the Washington Post, Slate, the Boston Globe, Aeon, among other publications. A graduate of Boston College, he was a 2015 journalist-in-residence at the Duke University National Evolutionary Synthesis Center and a 2011 Woods Hole Oceanographic Institution Ocean Science Journalism Fellow.
