Staff Writer Paul Voosen talks with host Sarah Crespi about how Arctic sea ice is under attack from above and below—not only from warming air, but also dangerous hot blobs of ocean water.

Next, Damien Fordham, a professor and global change ecologist at the University of Adelaide, talks about how new tools for digging into the past are helping catalog what happened to biodiversity and ecosystems during different climate change scenarios in the past. These findings can help predict the fate of modern ecosystems under today’s human-induced climate change.

And in our books segment, Kiki Sanford talks with author Carl Bergstrom about his new book: Calling Bullshit: The Art of Skepticism in a Data-Driven World.
