The West Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere. It is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice ...
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 Advisory Committee on Antarctic Names approved the name in 1962. West Antarctica is mostly covered by a massive ice sheet referred to as the West Antarctic Ice Sheet. In recent decades, this ice sheet has shown signs of decreasing mass. [4] The geologic history of West Antarctica was summarized in a 2020 publication. [5]
The West Antarctic Ice Sheet holds enough water to raise sea levels by about 5 meters – more than 16 feet — which would cause devastating flooding in coastal towns and cities around the world.
Scientists say warming trend in West Antarctica is already on a trajectory that cannot be reversed under various emission scenarios Future melting of Antarctic Ice Sheet ‘unavoidable ...
The Antarctic ice sheet is melting in a new, worrying way not taken into account by current models of future sea level rise, according to a new study. ... professor of Earth system science at the ...
The WAIS Divide is the ice flow divide on the West Antarctic Ice Sheet (WAIS) which is a linear boundary that separates the region where the ice flows to the Ross Sea, from the region where the ice flows to the Weddell Sea. It is similar to a continental hydrographic divide.
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
