Doomsday Glacier: New Seafloor Map Reveals Accelerated Ice Loss

New seafloor map shows that ‘Doomsday Glacier,’ which scientists had thought was already on the brink of disaster, is even more dangerous than they originally believed.

Robots under the sea peered at Antarctica’s Thwaites Glacier (nicknamed \”Doomsday Glacier\”). They saw that it may be doomed sooner than expected due to an extreme spike in melting ice. The detailed map of seafloor around the icy giant has revealed that it experienced periods of rapid retreat in the past few centuries. This could be triggered by melting driven by climate changes.

Researchers said that the glacier’s total liquidation could result in global sea levels rising between 3 to 10 feet (0.93 and 3.0 meters). This is why it has been given its ominous name. According to the International Thwaites Glacier Collaboration, climate change is causing the massive frozen mass to retreat twice as fast as 30 years ago. It is also losing about 50 billion tons of ice per year.

Thwaites Glacier is held in position by jagged points of the seafloor, which slow down the glacier’s descent into the water. The \”grounding point\” is a section of the seafloor that grabs hold of the underbelly of a iceberg. It plays a crucial role in how fast a calving glacier can move.
