The Thwaites ‘Doomsday Glacier’ is living up to its name, and scientists are officially freaking out. Cracks have doubled in length over 20 years, and now the ice shelf is basically hanging on by a thread. Warmer ocean water is making things worse, creating a vicious cycle of melting. If this keeps up, rising sea levels could be a real-life disaster movie for coastal cities. Mother Nature’s not playing around! #Science #DoomsdayGlacier #ClimateChange
