A huge iceberg, named as D28, in Antarctica broke off last 3 years in 2019. This caused a lot of changes in the movements of the icebergs. But according to scientists, it is a normal phenomenon and climate change isn’t to blame.
Based on the observations from European and American satellites, the ice calving of Amery ice shelf happened on September 25.
The iceberg measures 632 square miles or 1,636 square kilometers. Meanwhile, in terms of thickness, it is about 210 meters, containing 347 billion tons of ice.
A glaciologist and professor at the Scripps Institution Scripps Institution of Oceanography in San Diego, Helen Amanda Fricker, shared the news on Twitter Monday, September 30.
Fricker said the figures are really massive; however, the production of iceberg is only a part of the normal cycle of ice shelves.
“Ice shelves have to lose mass because they gain mass. They want to stay the same size,” she said.
The mass gains of D28 were from the snow that fell on the continent and from the glaciers that approached the shore.
Eastern Antarctica, where the iceberg broke away, is not similar to the Western part and Greenland, which are rapidly warming because of climate change.
“It’s really important that the public doesn’t get confused and think that this is climate change,” Fricker advised.
The professor said this as breaking off of an iceberg called A68 of about three times the size of D28 alarmed people two years ago.
