50 4 Full Breakdown

Summary

Story summary

The Thwaites Eastern Ice Shelf, also known as the Doomsday Glacier, shows cracks forming and accelerating toward collapse based on more than two decades of satellite and GPS data.
Its loss would raise global sea levels by up to 65 centimeters.
The ice shelf stabilizes the glacier, so weakening could trigger issues in other Antarctic regions and threaten low-lying coastal areas worldwide.
The research is part of the TARSAN project.
