Scientists looked deep under the Doomsday Glacier. What they found represents a potential disaster for the planet

Scientists using ice-breaking ships and underwater robots have found that Antarctica's Thwaites Glacier is melting at an accelerating rate and could be on an irreversible path to collapse, spelling disaster for global sea-level rise. Since 2018, a team of scientists making up the International Thwaites Glacier Collaboration has been studying Thwaites – often called the “Doomsday Glacier” – up close to better understand how and when it might collapse.

Their findings, presented in a set of studies, provide the clearest picture yet of this complex, ever-changing glacier. The outlook is "bleak", the researchers said in a report published on Thursday, which reveals the key conclusions of their six-year research. (Laura Paddison, more at edition.cnn.com)
