Ice shelves around the Antarctic Peninsula are
retreating
[5]. These ice shelves are warmed from below by changing ocean currents, thinning them and making them vulnerable. During warm summers, ice shelves calve large icebergs – and in some cases, can catastrophically collapse.
What has happened to the Wilkins ice shelf in Antarctica?
In March 2008, the Wilkins Ice Sheet on the Antarctic Peninsula
lost more than 400 square kilometers (160 square miles) to a sudden collapse
. Following that event, the Wilkins continued to break up, even as the Southern Hemisphere winter brought frigid temperatures to the fragile ice shelf.
What is happening to Antarctica's ice shelves?
Ice sheet tipping points
Since the early 1990s, Antarctica has lost roughly three trillion tons of ice. Today,
the rate of loss is accelerating as warm ocean water melts and destabilizes
the floating ice shelves that hold back West Antarctica's glaciers, causing those glaciers to flow more quickly into the sea.
Will there be another ice age?

begin within 1,500 years
. They go on to predict that emissions have been so high that it will not.
