@dailymail: Antarctica's 'Doomsday Glacier' is even more dangerous than scientists had previously thought, a new study has found. The Thwaites Glacier in western Antarctica is a huge river of ice covering an area larger than Great Britain. If it were to collapse completely, it has the potential to raise sea levels by a staggering 26 inches (65 centimetres) and impact the world's coastal regions. While researchers don't believe a total collapse is imminent, they warned the glacier is now accelerating towards disaster. New predictions reveal warming ocean waters are eroding its base faster than expected, and could add up to 1.2 inches (30mm) of sea level rise by 2100 - doubling previous estimates. #glacier #ice #antarctica #climate
