A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to UC Irvine Earth system science prof. Eric Rignot and colleagues at NASA. A collection of media highlights:
Volume of melted ice enough to raise global sea level by 4 feet Irvine, Calif., May 12, 2014 - A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to researchers at UC Irvine and NASA.
May 12, 2014 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.
A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday. If the findings hold up, they suggest that the melting could destabilize neighboring parts of the ice sheet and a rise in sea level of 10 feet or more may be unavoidable in coming centuries.
For decades, the inevitability of many feet, even yards, of sea-level rise in a warming climate has been crystal clear. But society's response, both in stemming heat-trapping greenhouse gas emissions and adapting to eroding coastlines, will always be more a function of the rate of change than the ultimate outcome.
A slow-motion and irreversible collapse of a massive cluster of glaciers in Antarctica has begun, and could cause sea levels to rise across the planet by another 4 feet within 200 years, scientists concluded in two studies released Monday.
You’ve been hearing it more often lately: Things are warming up faster than scientists had predicted. Now, a study out of UC Irvine and the Jet Propulsion Laboratory ups the ante, saying that rapidly melting ice in Antarctica contains enough mass to raise the global sea level by 4 feet.
Warm, naturally occurring ocean water flowing under the glaciers is causing the melt. "We feel it is at the point that it is . . . a chain reaction that's unstoppable," regardless of any future cooling or warming of the global climate, said Eric Rignot, a professor of Earth science at the University of California at Irvine.
Scientists have long worried about climate-change induced melting of the huge West Antarctic Ice Sheet. Now they say that not only is the disintegration of the ice already underway, but that it's likely unstoppable. That means that in the coming centuries, global sea levels will rise by anywhere from 4 to 12 feet.
Key glaciers in West Antarctica are in an irreversible retreat, scientists led from the US space agency (Nasa) say. They analysed 40 years of observations of six vast ice streams draining into the Amundsen Bay and concluded that nothing now can stop them melting away.
Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, "unstoppable" process that could raise sea levels by as much as 15 feet.
The huge West Antarctic ice sheet is starting a glacially slow collapse in an unstoppable way, two new studies show. Alarmed scientists say that means even more sea level rise than they figured. The worrisome outcomes won't be seen soon. Scientists are talking hundreds of years, but over...
