Thwaites Glacier: Eastern Ice shelf could break up within five years

The Thwaites Glacier, also known as the Doomsday Glacier, is a critical ice mass in Antarctica. It acts as a dam, slowing ice flow into the ocean. However, it is currently thinning and developing fractures, which could lead to its collapse within five years. This would release large sections of the glacier into the ocean, significantly raising global sea levels. The glacier's collapse could eventually lead to the loss of the entire West Antarctic ice sheet, causing a 3.3-meter rise in sea levels. The situation is likened to a windshield with cracks that suddenly shatter.
