Vast Iceberg poised to crack off Antarctica

A rift, slowly developing across the Larsen C ice shelf on the Antarctic Peninsula in recent years, expanded abruptly last month, growing by about 18 km. It is now more than 80 km long with just 20 km left before it snaps, scientists said.

“The Larsen C Ice shelf in Antarctica is primed to shed an area of more than 5,000 square km following further substantial rift growth,” scientists at Project Midas at the University of Swansea in Wales said in a statement.

The iceberg “will fundamentally change the landscape of the Antarctic Peninsula” and could herald a wider break-up of the Larsen C ice shelf, the statement said.

Ice shelves are areas of ice floating on the sea, several hundred metres thick, at the end of glaciers. Scientists fear the loss of ice shelves around the frozen continent will allow glaciers inland to slide faster towards the sea as temperatures rise because of global warming, raising world sea levels.
