Doomsday Scenarios, ep. 2: The glacier actually nicknamed 'Doomsday'

This episode of KYW Newsradio In Depth is part two of a mini series called Doomsday Scenarios, where we ask very smart people if this, that, or the other thing could destroy life as we know it. Today: Have you ever heard of the Thwaites Glacier in Antartica? If not, you will soon enough and won’t like why. It's massive, it's collapsing, and when it goes - sea levels are going to rise by a significant amount. We asked Dr. Amanda Grannas, Villanova University chemistry professor and the vice provost for research and chief research officer to come on the podcast and talk about why the Thwaites Glacier is important.
