Heat from the deep ocean is shifting toward Antarctica posing a growing threat to the continent’s delicate ice shelves, lining its coast and helping stabilize the ice sheet. Ice shelves act as barriers that hold back Antarctica’s inland glaciers and ice sheets. Together, these frozen reserves contain enough water to raise global sea levels by about 190 feet (58 meters).
