Almost one-quarter of the ice in the West Antarctic ice sheet has been classified as "unstable," according to a new study released this week. This is due to the huge volume of ice . A new study by researchers at NASA and the University of California at Irvine finds a rapidly melting section of the West Antarctic ice sheet appears to be in an irreversible state of decline.

For half a century, climate scientists have seen the West Antarctic ice sheet, a remnant of the last ice age, as a sword of Damocles hanging over human civilization.. The great ice sheet, larger.
Although the Antarctic Ice Sheet is a continuous mass of ice, but it is sometimes helpful to think of it as two separate masses known as the West Antarctic and East Antarctic ice sheets, which are separated by the Transantarctics. Ice on the west side of this line flows west, while the opposite happens east of the divide. If the ice sheet collapses, even only partially, that's a tremendous amount of ice that will go into the planet's oceans, causing sea levels to rise around the globe. It's estimated that West Antarctica contains about million cubic kilometers of ice, which if the entire ice sheet goes, could lead to more than three meters of sea-level rise.

InHughes published a closer look at the Amundsen Sea region specifically. He called it "the weak underbelly of the West Antarctic ice sheet." Here's the cause for concern: When the ice sheet is attached to a bed below sea level, ocean currents can deliver warm water to glacier grounding lines, the location where the ice attaches to the bed.
Most researchers had believed that the West Antarctic ice sheet hadn’t been much smaller than it is now for at leastyears. “We were really surprised,” says Reed Scherer. The WAIS Divide ice core project (West Antarctic Ice Sheet Divide ice core project) investigated past climate changes, ice sheet dynamics and cryobiology.
The project was completed by the United States Antarctic Program (USAP) and was funded by the National Science Foundation (NSF). The focus of the project was to develop records spanning the last ~ 80, years of the concentration of greenhouse gases in the atmosphere and Antarctic.

The West Antarctic Ice Sheet alone could boost sea levels an average of 10 feet if it melts – an increase that would occur over hundreds to thousands of.
The fragile Antarctic environment consists of a closely linked system of the lithosphere, atmosphere, cryosphere, hydrosphere and biosphere. Changes in this system have influenced global climate, oceanography and sea level for most of Cenozoic time. The geological history of this region therefore provides a special record of important interactions among the various components of the Earth System.
The Marie Byrd Land mantle plume formed 50 to million years ago, long before the West Antarctic ice sheet came into existence. At the end of the last ice age aro years ago, the ice sheet went through a period of rapid, sustained ice loss when changes in global weather patterns and rising sea levels pushed warm water closer to the.
Recent ice loss from the West Antarctic Ice Sheet has been caused by ocean melting of ice shelves in the Amundsen Sea. Eastward wind anomalies. The Los Angeles Review of Books is a (c)(3) nonprofit.
Help us create the kind of literary community you’ve always dreamed of. In telling the story of the West Antarctic ice sheet for. ‘The West Antarctic Ice Sheet is one of the tipping elements in our climate system.
Ice loss is accelerating and might not stop until the West Antarctic ice sheet is practically gone.’. While the important connection between heat and water has long been known to be critical to understanding processes beneath the Antarctic ice streams [e.g., Blankenship et al., ], a growing interest in the basal hydrologic conditions beneath West Antarctic Ice Sheet (WAIS) has been motivated by both the discovery of extensive subglacial.
A new paper suggests that the East Antarctic ice sheet may not be as stable as we thought. Looking at ancient melting, the study finds evidence that this piece of the Antarctic experienced meltingyears ago when the world was to degrees Fahrenheit (1 to 2 degrees Celsius) warmer.
Enough ice melted could have occurred here to raise the sea by about 10 to 13 feet. A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea.
T he West Antarctic Ice Sheet is one of the keys to global sea level rise. Running up against the Amundsen Sea, it contains an estimatedcu. miles ( million cu. km) of ice. The huge West Antarctic ice sheet is starting a glacially slow collapse in an unstoppable way, two new studies show.
Alarmed scientists say that. Using samples taken from the WDC06A ice core drilled during the ‘’08 West Antarctic Ice Sheet (WAIS) Divide field season, bubble sections were prepared and digitally imaged at the National Ice Core Lab in Lakewood, CO.
These images were then manipulated, error-checked and reduced into workable bubble number-density data.The base of the West Antarctic Ice Sheet actually sits well below sea level, and scientists worry that this makes the ice sheet especially at risk of irreversible collapse if it loses a certain.Published in the journal Science Advances, researchers from the U.S.
and Germany assessed whether artificial snowfall could save the West Antarctic Ice Sheet—an area containing about million.
