The Thwaites Glacier (aka the Doomsday Glacier) in Antarctica is melting way faster than scientists thought. New research shows cracks are speeding up the ice flow, making the glacier less stable and raising the risk of major sea level rise. If this giant goes, cities like NYC and London could face serious flooding. Basically, the planet just got a big, icy warning sign. Anyone else suddenly worried about beachfront property? #Science #DoomsdayGlacier #ClimateChange
