Melting the World’s Biggest Ice Cube

Antarctica has 90 percent of the world’s ice–and it’s melting. Ice sheet guru Bob Bindschadler talks about climate change in Antarctica, and rising sea levels across the globe. Plus, biologist Diana Wall talks about hidden life in the barren Dry Valleys, and microbe hunter John Priscu talks about “bugs in the ice.”
