About this episode

Brent Minchew discusses his plan to stop the Thwaites Glacier from contributing to sea level rise.

Brent Minchew could have a plan to stop Thwaites Glacier, AKA the “Doomsday Glacier”, cold in its tracks. That’s good news because if this one glacier slips into the sea, it could flood coasts across the planet. The Caltech glaciologist covers what makes the “Doomsday Glacier” the single biggest wild card in sea level rise, the simple idea that could freeze it back to its bed, and his own improbable journey from 9/11 first responder to two of the world's top science institutions. It's a conversation about glaciers, courage, and what it takes to change the story.
