More Than Half The Ice Shelves Currently Buffering Antarctica Are at Risk of Crumbling – ScienceAlert

More than half the ice shelves ringing Antarctica that prevent huge glaciers from sliding into the ocean and lifting sea levels are at risk of crumbling due to climate change, researchers said Wednesday.
Melt water running into deep fissures caused by warming air is undermining the structural integrity of these natural barricades, they reported in Nature.
“If the ice shelves fill up with melt water, things can happen very quickly,” said co-author Jonathan Kingslake, a glaciologist at Columbia …
