Scientists issue warning as 'Doomsday Glacier' nears tipping point: 'Every single day we have a look'
The Cool Down••science
Key Points:
- A study published in the Journal of Geophysical Research reveals that the Thwaites Eastern Ice Shelf in Antarctica, part of the rapidly changing Thwaites Glacier, has weakened structurally due to expanding fractures over two decades.
- The collapse of Thwaites Glacier could cause sea levels to rise by approximately 65 centimeters (over two feet), with the ice shelf retreating nearly 1 kilometer annually over the next 40 years.
- Arctic ice is melting at an accelerated rate, warming three times faster than the global average, leading to a 60% decline in sea ice since 1900 and contributing to rising sea levels that threaten parts of the U.S. with up to 2 feet of increase by 2050.
