The news is of particular concern because the ice in question acts as a sort of cork, preventing some of Antarctica's glaciers from flowing in to the ocean.

The crack has grown by over 17km during December alone and is now a total of 180km in length.If the ice does break away then it could lead to a global sea level rise of up to 10 centimeters.

"When it calves, the Larsen C Ice Shelf will lose more than 10 per cent of its area to leave the ice front at its most retreated position ever recorded; this event will fundamentally change the landscape of the Antarctic Peninsula," the researchers said in a statement.

"We have previously shown that the new configuration will be less stable than it was prior to the rift, and that Larsen C may eventually follow the example of its neighbour Larsen B, which disintegrated in 2002 following a similar rift-induced calving event."
