The world’s largest iceberg, A68a, will melt in three years, satellite data show | Climate News

According to satellite data, the world’s largest iceberg has virtually melted.

A block of 5,800 square kilometers (2,239 square miles) of ice known as A68a Antarctic Larsen Ice Shelf on the Peninsula in July 2017.

However, satellite imagery now shows that the iceberg is split into smaller pieces, which are too small to be tracked further, the US National Ice Center said.

The iceberg spent two years without moving far before being caught up in the powerful currents that propelled it northeast.

Its structure attracted attention when it looked like that last December May hit South Georgia, While traveling on the Antarctic front.

There was concern that if it had an impact, it would threaten the island’s diverse wildlife.

The Royal Air Force reconnaissance aircraft was created to capture images of the A68a and predict where it will move.

At this point, the A68a was 4,200 square kilometers (1,622 square miles), but this year it has shrunk further, with several icebergs delivering since January.

The climatic situation is “very urgent”

The last clear image of the A68a was taken on Friday. It showed that the iceberg had shrunk to just 3 x 2 nautical miles.

The US National Iceberg, which names, tracks, and documents Antarctic icebergs, is studying only icebergs that measure at least 20 nautical miles or 10 nautical miles on the longest axis.

The center told Sky News that it would not issue an official statement about the end of the A68a, but confirmed that it was below the minimum size standard used to track icebergs.
