The Thwaites Glacier in western Antarctica is the widest glacier on Earth, spanning approx 80 miles. It’s also melting and rapidly becoming more unstable. The glacier is known as the 'Doomsday Glacier’ because if it were to break up entirely, global sea levels would rise by 2 feet. Its collapse could also trigger a string of glacial collapses in Antarctica, and if the surrounding glaciers were to fail with the Thwaites, global sea levels could rise by up to 10 feet.
