“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.
