A temperature rise of three or four degrees doesn\\u2019t seem like a big deal\\u2026 Until you go back a few million years and start exploring what the world looked like the last time the Earth was that hot and CO2 levels were even higher than they are now.

\\n

Peter Brannen is an award-winning science journalist. His work has appeared in The New York Times, WIRED and The Guardian, among many other national publications. He is also the author of The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth\\u2019s Past Mass Extinctions. On this episode of Reversing Climate Change, Peter joins Ross to discuss his most recent article in The Atlantic, \\u2018The Terrifying Warning Lurking in the Earth\\u2019s Ancient Rock Record.\\u2019 

\\n

Peter explains what the planet was like during the Pliocene (the last time CO2 reached 400 PPM), the Miocene (500 PPM) and the Eocene (600-plus PPM), describing how rising levels of carbon dioxide might transform the Earth as we know it. Listen in for Peter\\u2019s insight on what an understanding of deep time can teach us about the impact climate change has on the planet and help us appreciate the difference three degrees can make.
