In this eighth part of our mini-series on climate science, we tackle the subject of ice and melting, and how much sea-level rise it may produce. What if that viral story about a starving polar bear may not even have been accurate? What does it really mean when we say that a worst-case climate model projects 11 feet of sea level rise, and is that even a plausible scenario? What does it mean to say that sea ice is melting at the fastest rate in 1,500 years? How much sea level rise might actually result from ice shelves breaking off? And how can we relate the latest studies on melting glaciers and ice caps to degrees of global warming or meters of sea level rise? These aren’t easy questions to answer, but our guest in this episode has about as good a shot at answering them as anyone. His nuanced and deeply informed view of what’s happening to our glaciers and ice caps in this 90-minute interview is refreshing, thoughtful, and provocative, and offers an educational counterpoint to the usual simple projections of climate doom.
