Summary

Story summary

Research shows that the stability of the Antarctic Ice Sheet is threatened by rapid sea ice loss, which occurs before major calving events.
A study identified that sea ice loss happened 6 to 18 months before three significant calving incidents, amplifying ocean swell impacts on ice shelves.
Mathematical models indicate that less sea ice allows ocean swells to flex ice shelves more than expected, increasing calving likelihood.
The 2025 Antarctic sea ice minimum was the second lowest on record, reflecting unprecedented retreat rates.
These findings suggest an increased risk of large-scale calving events, potentially raising global sea levels significantly.
