The iceberg, known as A68a, had also broken off from the Larsen Ice Shelf, which has warmed faster than any other part of Earth's southern most continent.Ī68a, which was 160 kilometres long and 48 kilometres across, broke up before it could cause any damage to the abundant wildlife in the British Overseas Territory of South Georgia.Įarth's average surface temperature has gone up by one degree Celsius since the 19th century, enough to increase the intensity of droughts, heat waves and tropical cyclones.īut the air over Antarctica has warmed more than twice that much. In November last year, what was then the world's largest iceberg appeared to be on a collision course with a remote South Atlantic island home to thousands of penguins and seals, threatening to impede their ability to gather food. It takes the place as the world's largest from the A-23A iceberg - approximately 3,880 sq km in size - which is also in the Weddell Sea. The berg, which broke off the western side of the Ronne Ice Shelf, was originally spotted by the British Antarctic Survey and confirmed using images from the Copernicus satellite. The iceberg is around 170 kilometres (105 miles) long and 25 kilometres wide, with an area of 4,320 square kilometres, slightly larger than the Spanish island of Majorca.

“It’s important to monitor the frequency of all iceberg calving, but these are all expected for now.”ĮSA said the title of “largest iceberg” was previously held by the almost 1,500-square-mile large A-23A.Called A-76 and roughly the shape of Manhattan but more than 70 times bigger, it was picked up on satellite images and is "currently the largest berg in the world", the ESA said Wednesday. The iceberg broke off the western side of the Ronne Ice Shelf in Antarcticas Weddell Sea, the European Space Agency (ESA) said Wednesday. “A76 and A74 are both just part of natural cycles on ice shelves that hadn’t calved anything big for decades,” British Antarctic Survey’s Laura Gerrish tweeted on May 14. Nevertheless, experts told The New York Times on Thursday that A-76 may not have separated from the shelf strictly due to climate change. And over the longer term, of course, it will have wide-ranging impacts in different locations around Antarctica.” “Climate is responsible for these changes. “Parts of Antarctica are in arrears, and that’s largely a consequence of increase in temperature or large calving events that have removed ice and destabilized the ice shelves themselves,” ESA senior scientist Mark Drinkwater told The Associated Press. Quick image from showing #Sentinel1 imagery from today (14th). Scientists reported an increase of 0.8 trillion tons per year in the 1990s to 1.3 trillion tons per year by 2017.Ī January paper published in the journal Science Advances found that ice losses have soared from 760 billion tons annually in the 1990s to more than 1.2 trillion tons in the 2010s.Īnother big iceberg calving event in #Antarctica! #A76 has calved from the Ronne Ice Shelf and is currently the biggest iceberg in the world, taking the record from neighbouring A23a. While ice shelves pretty regularly lose ice, scientists tie worryingly rapid loss to the impacts of a warming climate.Ī University of Leeds study from January reported that the rate at which ice is disappearing has increased markedly. The 2,300-square-mile A-68 iceberg that calved from Antarctica’s Larsen C ice shelf in 2017 has since melted away. LiveScience reported on Thursday that the event would not directly impact sea levels. The 1,668 square-mile ice mass split from the Ronne Ice Shelf into the Weddell Sea and is anticipated to eventually drift into the South Atlantic where it would disintegrate. It was also confirmed by the US National Ice Center (USNIC), which tracks and names Antarctic icebergs that are at least 10 nautical miles long or 20 square nautical miles large. The iceberg is named A-76 and is more than 40 times the size of Paris, larger than the state of Rhode Island and 73 times as big as Manhattan.Ī-76, named for the quadrant in which it was first located - was first seen by researchers at the British Antarctic Survey using ESA’s Sentinel 1A satellite.
