Summary
Published in Nature, this collaborative work reveals that more than half of Antarctica's ice shelves could become unviable due to ocean warming. We demonstrate that subsurface ocean temperatures are rising faster than expected, accelerating basal melt and destabilizing the ice-sheet gates.
Key Takeaway
"60% of Antarctic ice shelves are at risk of losing their structural integrity, a critical tipping point for global sea-level rise."
