It seems that the Antarctic ice sheet came close to collapse in the past. In a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica due to winds blowing from the cooler sea to the warmer land. This could trigger processes that accelerate further ice loss. Rain falling on the ice sheet can cause fracturing, surface melt and extra freshwater running off the continent, which, in turn, can cause deep-sea temperatures to rise — potentially influencing Antarctic ice from beneath.
