Antarctic ice growing, not shrinking.Byline: ANI Sydney, April 18 (ANI): New analysis has indicated that contrary to the belief that there is large-scale melting of ice over most of Antarctica, ice is actually expanding in a large portion of the continent. Antarctica has 90 per cent of the Earth's ice and 80 per cent of its fresh water. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica West Antarctica, or Lesser Antarctica (), is one of the two major regions of Antarctica, lying on the Pacific Ocean side of the Transantarctic Mountains and comprising Marie Byrd Land, Ellsworth Land, and Antarctic Peninsula. . The destabilisation Noun 1. destabilisation - the action of destabilizing; making something less stable (especially of a government or country or economy) destabilization of the Wilkins ice shelf generated international headlines this month. However, according to a report in the Australian, the picture is very different in east Antarctica, which includes the territory claimed by Australia. East Antarctica is four times the size of west Antarctica and parts of it are cooling.

The Scientific Committee on Antarctic Research (SCAR) is a committee of the International Council for Science. report noted that the South Pole had shown "significant cooling in recent decades". According to Australian Antarctic Division The Australian Antarctic Division (AAD) is a division of the Department of the Environment and Water Resources. This is the Australian Government agency which manages Australia's Antarctic and sub-Antarctic stations and territories as part of the Australian Antarctic Program - glaciology glaciology Scientific discipline concerned with all aspects of ice on landmasses. It deals with the structure and properties of glacier ice, its formation and distribution, the dynamics of ice flow, and the interactions of ice accumulations with climate. program head Ian Allison, sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica. "Sea ice conditions have remained stable in Antarctica generally," Dr Allison said. The melting of sea ice - fast ice and pack ice - does not cause sea levels to rise because the ice is in the water. Sea levels may rise with losses from freshwater ice sheets on the polar caps. In Antarctica, these losses are in the form of icebergs calved from ice shelves formed by glacial movements on the mainland. Dr Allison said there was not any evidence of significant change in the mass of ice shelves in east Antarctica nor any indication that its ice cap was melting. "The only significant calvings in Antarctica have been in the west," he said. Ice core drilling in the fast ice off Australia's Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m. A paper to be published soon by the British Antarctic Survey Based in Cambridge, the British Antarctic Survey (BAS) is the United Kingdom's national Antarctic operator and has an active role in Antarctic affairs. BAS is part of the Natural Environment Research Council and has over 450 staff. in the journal Geophysical Research Letters Geophysical Research Letters is a publication of the American Geophysical Union. GRL is the organization's only letters journal. Since its introduction in 1974, GRL has published only short research letters, typically 3-5 pages long, which focus on a specific discipline or is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded.
