Thwaites Glacier melting at 300 times normal rate

The Thwaites Glacier in West Antarctica, frequently referred to as the ‘Doomsday Glacier’, is melting at an exceptionally high rate, approximately 300 times faster than normal. Scientists aboard the South Korean icebreaker Araon observed that seawater beneath the ice was nearly 6.5 degrees Celsius warmer than the freezing point of glacier ice in seawater.

The glacier is losing roughly 90 meters of thickness annually, a significant increase from the typical loss of less than 30 centimeters. Thwaites contains enough ice to raise global sea levels by 75 to 90 centimeters. Furthermore, the glacier acts as a dam for the West Antarctic ice sheet; its collapse could lead to a sea-level rise of approximately 3 meters.

Research efforts are currently facing challenges as funding for crucial climate studies comes under pressure. In the United States, government cuts to a primary scientific icebreaker vessel threaten to reduce Antarctic research capabilities.
