Antarctica's ice shelves could be melting faster than we thought

Phys Dot Org 12 Aug 2022
The model accounts for an often-overlooked narrow ocean current along the Antarctic coast and simulates how rapidly flowing freshwater, melted from the ice shelves, can trap dense warm ocean water at the base of the ice, causing it to warm and melt even more ... the West Antarctic Peninsula (WAP).

Researchers Warn of Melting Antarctic Ice Sheet

Beijing News 11 Aug 2022
SYDNEY - Australian and other scientists are warning that runaway climate change could melt the East Antarctic Ice Sheet, causing sea levels to rise by up to 5 meters.
