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.

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.
