The Thwaites 'Doomsday Glacier' in Antarctica is melting way faster than scientists hoped, and if it collapses, it could raise sea levels by 65cm—enough to put major cities and millions of people at risk. The wild part? Over 40% of us live near the coast. Researchers are using underwater robots to track it, but the clock’s ticking. If the whole West Antarctic Ice Sheet goes, we’re talking a 3.3m sea level rise. Climate change just got real, folks. #Science #DoomsdayGlacier #ClimateCrisis
