In late February 2022, an iceberg with an area of about 490 square miles, or slightly less than twice the size of the City of New York, calved from the Brunt Ice Shelf in the Weddell Sea section of Antarctica. Now, just under a year later, another iceberg has calved from the Brunt Ice Shelf. The new iceberg, with an area of 1550 square kilometers (about 600 square miles), is also roughly twice the size of New York City. The U.S. National Ice Center has named it Iceberg A-81. According to the British Antarctic Survey (BAS), the break occurred late on January 22, 2023.
The good news is that the split is a natural process and is not linked to climate change, the British Antarctic Survey says.
