Huge iceberg breaks off, but…
A more than 600-square-mile iceberg broke off Antarctica in recent days, but relax, the event is part of a normal cycle and is not related to climate change.
The iceberg, dubbed D28, broke away from the Amery ice shelf between September 24 and 25, according to observations from European and American satellites.
It measures 1,582 square kilometers (610 square miles), according to the European Copernicus program.
It is about 210 meters (yards) thick and contains 315 billion tonnes of ice. The figures are huge, but iceberg production is part of the normal cycle of ice shelves, which are an extension of the ice cap, she said.
The gain in mass comes from snow falling on the continent and glaciers that move slowly toward the shore.
The east of Antarctica — where D28 broke off — is different from the west of the continent and Greenland, which are rapidly warming due to climate change.
An iceberg that was three times larger broke off Antarctica two years ago.
The average thickness of Antarctic ice is about 1.6 kilometers and its Ice Sheet is the largest single mass of ice on Earth.
