What's Really Under Antarctica's Ice?

Check out our Patreon: https://www.patreon.com/cw/PBSWeather... If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - which holds around 5 METERS of sea level rise - is melting a lot faster than scientists once thought. And, a new study warns of a sinister threat buried deep beneath the melting ice - one that may cause a feedback loop that speeds up the melt of the already precarious West Antarctic ice sheet. Stay tuned to find out what new maps reveal about the under-ice world of Antarctica, and how a tiny octopus can help us understand the South Pole’s ice-free past. ***** PBS Member Stations rely on viewers like you.
