The study was published Monday in the peer-reviewed journal Geophysical Research Letters, a publication of the American Geophysical Union. There has been lots of talk lately about Antarctica and whether or not the continent’s giant ice sheet is melting. ... not counting the contribution from Greenland and other glaciers. Monday 13 July 2020 20:18. September 25, 2020. Pine Island and Thwaites glaciers already contribute 5 percent of sea-level rise. This giant glacier in Antarctica is melting, and it could raise sea levels by 5 feet, scientists say By Leah Asmelash, CNN Updated 2110 GMT (0510 HKT) March 25, 2020 Overall, NOAA said global sea levels have risen about 8 to 9 inches since 1880, and about a third of that is coming in just the last 2½ decades. Between 1979 and 2017, the glacier experienced a cumulative mass loss of 268 billion tons of ice, according to the study, which was published on Monday. Researchers trying to understand what's happening have drilled down through seven-hundred metres of ice, to allow a robot submarine to gather information. Thwaites Glacier: Antarctica's colossal glacier is melting fast -- and scientists may have discovered why By Emma Reynolds, CNN 9/9/2020. Ice melt accelerating:Greenland and Antarctica are now melting six times faster than in the 1990s, accelerating sea-level rise. Scientists in Antarctica have recorded, for the first time, unusually warm water beneath a glacier the size of Florida that is already melting and contributing to a rise in sea levels. Antarctica's "most terrifying glacier" 04:19 Scientists have found warm water beneath Antarctica's "doomsday glacier," a nickname used because it is one of Antarctica's fastest melting glaciers. ... Todd Haugen 05 April 2020 17:37. Accessed February 5, 2020. International Thwaites Glacier Collaboration (2020) About the ITGC. “East Antarctica has long been thought to be less threatened (than West Antarctica), but as glaciers such as Denman have come under closer scrutiny by the cryosphere science community, we are now beginning to see evidence of potential marine ice sheet instability in this region,” said study co-author Eric Rignot, a scientist at the University of California-Irvine. The glacier acts as a buffer between the warming sea and other glaciers. The region contains enough ice to raise sea levels by 3 meters, and it’s melting faster each decade. Researchers used radar data from aboard a satellite to measure the ice loss. Thwaites Glacier, also known as the "doomsday glacier", is reported to be melting quicker than previously thought - scientists are now trying to find out why. As the global climate heats up, some of the great ice sheets and glaciers in Antarctica are melting, a few of them rapidly. Hospitals seek reinforcements as COVID surges.

Climate change: Worsened Australia's catastrophic wildfires, study says. Antarctica's Thwaites Glacier, described as the "most important" glacier in the world, is now melting faster than previously thought. Pine Island Glacier has a crack tens of kilometers long and is one of Antarctica's fastest flowing rivers of ice, moving 4,000 meters a year, according to the report. National Oceanic and Atmospheric Administration. Melting is especially marked in west Antarctica, according to WMO, and to a lesser extent along the peninsula and in east Antarctica. Scientists are studying why the Thwaites Glacier is melting quicker than previously thought. The Denman glacier experienced a loss of 268 billion tons of ice from 1979 to 2017, according to the study. Most of that rise is because of meltwater from glaciers and ice sheets and the expansion of seawater as it warms. It's getting warmer down at the bottom of the world. Thwaites Glacier: Antarctica's colossal glacier is melting fast -- and scientists may have discovered why By Emma Reynolds, CNN 9/9/2020. "If fully thawed, the ice in Denman would cause sea levels worldwide to rise almost 5 feet," the University of California-Irvine said in a statement. Richard Alley, a Penn State University glaciologist who was not involved in the study, told The Washington Post that “this study provides additional evidence that, based on current knowledge, we cannot exclude at least a slight possibility of much more sea-level rise than the most-likely value in (Intergovernmental Panel on Climate Change) projections.". Antarctica is home to some of the world's largest ice sheets and glaciers. Greenland and Antarctica are now melting six times faster than in the 1990s, accelerating sea-level rise.

Antarctic glaciers are beautiful and awe-inspiring. One, East Antarctica’s Denman glacier, has retreated nearly 3 miles in just the past 22 years, according to a new study. There are many glaciers in the Antarctic.This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. Scientists may just have identified Thwaites Glacier's Achilles heel. Thwaites Glacier is one of the largest and most unstable ice streams in Antarctica. Deep channels discovered under the Antarctic's so-called "Doomsday glacier" may be allowing warm ... Antarctica's colossal Thwaites Glacier is melting fast ... By CNN. Antarctica's colossal Thwaites Glacier is melting fast - and scientists may have discovered why ... By CNN.

Melting on the ice cap of Eagle Island, Antarctica, during a warm period between Feb. 4 and Feb. 13, 2020, seen in images gathered using the Operational Land Imager (OLI) on Landsat 8. But the Denman Glacier is so big -- at around 10 miles wide -- that its potential impact on sea levels is "just as significant," he said. It's important here in the United States because almost 40% of the U.S. population lives in relatively high population-density coastal areas, where sea level plays a role in flooding, shoreline erosion and hazards from storms, according to the National Oceanic and Atmospheric Administration. The Pine Island Glacier is one of the fastest-melting glaciers in Antarctica. Article bookmarked. Why Antarctica’s 'Doomsday Glacier' is Melting So Fast. Two major Antarctic glaciers are tearing loose from their restraints, scientists say. And globally, eight of the world’s 10 largest cities are near a coast, the United Nations' Atlas of the Oceans reports. Skip to main content. (CNN) – Scientists collecting data on sea-level rise have discovered that deep channels under Antartica’s “Doomsday glacier” may be allowing warn ocean water to melt the underside of the ice.

It's been melting about 10 feet per year, which is above average compared to other East Antarctic ice shelves. Glaciologists have described Thwaites Glacier as the "most important" glacier in the world, the "riskiest" glacier, even the "doomsday" glacier. ... the same wind patterns led to a lot of surface melting," he said. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day.

If it fully thaws, sea levels would rise almost 5 feet. "Because of the shape of the ground beneath Denman's western side, there is potential for rapid and irreversible retreat, and that means substantial increases in global sea levels in the future," said the study's lead author Virginia Brancato, a postdoctoral fellow with NASA JPL. The warm spell caused widespread melting on nearby glaciers. A large swath of ice might be on the verge of breaking off of Antarctica and drifting off into the sea, according to Sky News. New analysis of Antarctica's melting glaciers refines our understanding of climate change, while risks of global impacts remain significant.
