Journalist and author David Brown joined a team of scientists for an expedition to the "Doomsday Glacier." In Antarctica, this particular glacier is viewed as critical for preserving a state of environmental balance. If climate change causes it to melt, the impact on sea levels will be enormous. So Brown and the team traveled on an ice breaker, spending weeks in the cold in an effort to get sensors under the glacier to measure signs of melt and change.
He joins us to talk about their dangerous and remarkable scientific expedition. Our guest:
- David Brown, contributor to the New Yorker, and the author of the book "The Mission"
