China News Service, April 21. According to a report by the British Broadcasting Corporation, satellite images show that the A68, once the largest iceberg in the world, melted and decomposed into "numerous small fragments", and actually no longer exists.
When A68 separated from the Antarctic continent in 2017, it covered an area of nearly 6000 square kilometers.
According to reports, A68 broke away from the Larsen C ice shelf at the edge of the Antarctic and barely moved for a year.
But then it began to drift northward at faster and faster speeds with the help of strong ocean currents and winds.
The iceberg entered the South Atlantic and reached South Georgia.
Many icebergs melted here, but A68 escaped this fate.

According to reports, what caused the final disintegration of the A68 iceberg was the waves in the Atlantic Ocean, warm sea water and higher air temperature.
It breaks down into smaller and smaller pieces.
Adrian Lukeman of Swansea University in the United Kingdom said, "When an iceberg moves in the ocean, it is very flexible and fragile... the iceberg splits into 4 to 5 pieces, and then these fragments also split."
The National Glacier Center said that the A68 fragments are no longer worth tracking.
Many glacier experts believe that the formation of A68 is a natural product and has nothing to do with climate change caused by humans.
But the changes in A68 do show how global warming may destroy the ice structure.
