World’s largest iceberg melts away
A68, as it was known, covered an area of nearly 6,000 sq km (2,300 sq miles) when it broke away from Antarctica in 2017. atellites show the mega-berg has now virtually gone, broken into countless small fragments that the US National Ice Centre says are no longer worth tracking.
A68a, an iceberg roughly the size of the state of Delaware, split off from Antarctica’s Larsen C ice shelf in July 2017. Since then it had been drifting towards the remote island of South Georgia, which is a British Overseas Territory. The had iceberg spent two years not moving far before it got caught in a powerful current that propelled it northeast.
The iceberg was larger than 66 countries or territories, including Singapore, Luxembourg and Brunei. The calving of an iceberg is a natural event and is not a result of climate change. According to some predictions, a warming Antarctica in the future could mean more calving events because of ice shelves and glaciers retreat.
