Scambos said that the ice shelf was already floating in the sea before breaking off, so the event does not raise ocean levels, whereas glaciers and ice sheets, found on land, do raise sea levels when they break off into the ocean. Ted Scambos, a research glaciologist at the University of Colorado at Boulder, told Reuters that this calving does not appear to be linked to climate change. Periodic calving of ice shelves is part of a natural cycle. NASA Scientists studying one of the most crucial glaciers that's been deteriorating by climate change got a new look at what's going on underneath the surface. An iceberg nearly the size of Greater London broke off the Brunt Ice Shelf in Antarctica on Sunday according to the British Antarctic Survey. An animation shows iceberg A-76 breaking off from Antarctica. February 16, 2023, 4:13 PM 1:00 Thwaites Glacier is seen in this undated photo. That iceberg measured about 93 miles long and 30 miles wide. William Hodges, although the first artist to sail within the Antarctic Circle, never saw the continent. Iceberg A68a, which was at one point the world's largest, was set on a collision course with a remote South Atlantic island last November, threatening the home of thousands of penguins and other wildlife, but broke into smaller chunks before it reached the island. Looking into the Emptiest Continent William L. The event pushes iceberg A-23A, which is 1,305 square miles and also floating in the Weddell Sea, into second place for the world's largest icebergs.
