Summary

Story summary

The Journal of Geophysical Research study shows the Thwaites Eastern Ice Shelf is disintegrating, with fractures traced over two decades as a pinning point weakens.
The pattern may signal risks for other Antarctic shelves and could affect global sea levels.
A Nature Geoscience study finds the East Antarctic Ice Sheet retreated about 9,000 years ago due to warm currents, indicating cascading feedbacks that spread ice loss regionally.
