Antarctica’s vast ice cap covers about as much of the earth as North America and is close to three miles (5km) thick. It holds more than half the earth’s fresh water. Some floats as sea ice, not destined to cause sea level rises in the way of ice melting from land yet subject to melting from above and below because of the warming sea.

Researchers examined how ice over land in the region can be expected to melt, and found a strong “hysteresis” effect, which makes it harder for ice to re-form than to melt. When the ice melts, its surface sinks lower down and sits in warmer air, so it requires lower temperatures for the ice to reform than it did to keep the existing ice stable.

If temperatures rose by 4C above pre-industrial levels, which some predictions say is possible if the world fails to reduce greenhouse gas emissions quickly, then the sea level rise would be 6.5 metres from the Antarctic alone, not counting the contribution from Greenland and other glaciers. That would be enough eventually to inundate all of the world’s coastal cities and cause devastation on a global scale. ... See more

Research says melting will continue even if temperature rises are limited to 2C
