Facebook/Instagram: The last remaining section of Antarctica's Larsen B Ice Shelf is likely to break up before the end of the decade. The first part of the ice shelf collapsed spectacularly in 2002, leaving behind a 625-square-mile remnant, which is about the size of Lake Superior and Lake Michigan combined. Scientists thought the remaining shelf was stable, but a new NASA analysis discovered that it's flowing faster than expected and has developed large cracks. Ice shelves act almost like dams for the glaciers behind them, so the final loss of Larsen B means the glaciers behind it can accelerate and increase the pace of global sea level rise.
