Giant iceberg breaks off east Antarctica

The calving of the 1,636 sq km iceberg is not linked to climate change, scientists say, but could speed up further melting

A gigantic iceberg about the size of greater London has calved from the Amery ice shelf in east Antarctica, according to expert monitors.

The tabular iceberg, officially named D-28, separated from the ice shelf on 26 September. The iceberg is 1,636 square kilometres in size, or about 50 x 30km, the Australian Antarctic Division said.
