Antarctica’s topography changed by major fracture – linked to global warming

A 5800 square kilometre iceberg, that weighs over a trillion tonnes, has broken away from the Larsen C Ice Shelf in Antarctica. It now stands as one of the biggest icebergs in recorded history. 

Scientists, who have been monitoring a growing fracture, announced that sometime between Monday 10th and Wednesday 12th July, the fracture completed, resulting in what they describe as a ‘calving’, meaning the iceberg is no longer connected to mainland Antarctica.

It is predicted that the iceberg, estimated to be twice the size of Luxembourg, will in the months and years ahead continue to break-up with portions floating northwards towards warmer waters.

The break is so massive that its separation has reduced the Larsen C Ice Shelf by approximately 12 per cent, changing the landscape of the Peninsula forever.
