An ice shelf the size of New York City has collapsed in East Antarctica, an area long thought to be stable and not hit much by climate change, concerned scientists said Friday. The collapse ...
An ice shelf protecting a key Antarctic glacier is breaking up faster than before, scientists say.
The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea. [1] As a smaller part of Antarctica, WAIS is also more strongly affected by climate change. There has been warming over the ice sheet since the 1950s, [3] [4] and a substantial retreat of its coastal glaciers since at least the ...
Antarctica's Thwaites Glacier is held back by a quickly melting underwater ice shelf that sits on a sea mount. Scientists say it is cracking. Antarctic ice shelf could crack, raise seas by feet ...
The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula [1] from Cape Longing to Smith Peninsula. It is named after Captain Carl Anton Larsen , the master of the Norwegian whaling vessel Jason , who sailed along the ice front as far as 68°10' South during ...
The calving of A-68 reduced the overall size of the Larsen C shelf by 12 percent. [5] [6] Historical data shows that many icebergs that break off from the Antarctic Peninsula reach South Georgia and the South Sandwich Islands. [7] The name "A-68" was assigned by the US National Ice Center. It broke into parts with the mother berg dubbed A-68A.
Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
The collapse of the 463-square-mile Glenzer Conger ice shelf, which occurred last week, came as temperatures rose in the eastern section of Antarctica by as much as 70 degrees Fahrenheit above normal.
