Study Finds Greenland Glaciers Losing 10 Billion Tons of Ice Per Year

The glaciers of northeast Greenland, long thought to be the most stable part of the massive Greenland ice sheet, are melting at an accelerating pace, losing roughly 10 billion tons of ice annually for the past decade, say researchers from the U.S. and Denmark.

This map shows major ice drainages in Greenland, along with measured ice surface velocities. The northeast Greenland ice stream (NEGIS) now appears to be retreating as rapidly, or perhaps more rapidly, than other parts of the ice sheet, including Jakobshavn Isbræ (JI), Helheim Glacier (HG) and Kangerdlugssuaq (KG). Catchments for those regions are outlined on the map. Image credit: The Ohio State University, Natural History Museum of Denmark

The finding will likely boost estimates of global sea level rise, which had previously not accounted for massive ice loss from that region, scientists say. The Zachariae ice stream in northeast Greenland, which drains 16 percent of the ice sheet, has retreated roughly 12.4 miles during the past decade, outpacing the fast-moving Jakobshavn glacier, which has retreated 21.7 miles over the last 150 years.

Ice loss from the region is likely accelerating, the researchers say, because ice dams in nearby bays that had been blocking the glaciers’ paths are now also melting, freeing the way for them to flow into the ocean.

“Northeast Greenland is very cold—it used to be considered the last stable part of the Greenland ice sheet,” explained the lead researcher of the report, which was published in Nature Climate Change. “This study shows that ice loss in the northeast is now accelerating. So, now it seems that all of the margins of the Greenland ice sheet are unstable.”

Other recent studies had estimated more moderate ice loss from Greenland’s northeast.

why was greenland named greenland ?i wonder if the vickings found greenland covered in ice or a garden spot,which would explain why warming is just natural and not caused by man.

Perhaps the ice buildup in the Antartic will compensate - or perhaps the ice build up in the Great Lakes will offset some of it, or perhaps what we think of today as "normal" is really abnormal and planet earth's more natural state is 10 degrees warmer, or 15 degrees colder, or .......

well if it has been retreating for 150 yrs that lets us out you need another scapegoat.

This is bad news. Recently scientists have noticed such a major retreat of winter ice in Alaska, that herds of Walrus are now coming on to land, much too early for the season. There is a also a decline of the Polar bear population.

The worst news is yet to come. Even slight increases in the earth's overall temperature causes a thawing of perma-frost especially in Siberia. When the perma-frost thaws trapped methane gas is released, which warms the atmosphere, causing more methane release. This is a vicious feed-back loop. The consequences??? Mass extinctions.

Time to restrict our consumption of fossil fuels.

Do the public want to listen to the 95% of scientists concerned about climate change? It would seem a lot wiser than listening to those Nobel Laureates Rush Limbaugh and Bill O'Reilly.

Perhaps you haven't listened to O'Reilly much - I haven't yet I heard him suggest exactly what you did - but then he's on that dreaded Fox so he must be disparaged.

Meanwhile, I'd love to hear you plan on restricting the use of fossil fuels, particularly in places like Russia, China and India.

Also, we've seen rapid decline in the number of people living in abject poverty - perhaps we need to return to those days of less fossil fuels and more starvation

Too much atmospheric warming will lead to "death control" of the human species. Florida amusement parks will need to be re-named "Venice-land". There is an alternative to overpopulation and starvation. Its called birth control. Combine it with lower carbon emissions and you have a formula for sustainability.

The ZPG movement needs to find its voice again.

Perhaps if you investigate ZPG you'd find it comes pretty much along with industrial development - the very thing you rail against without realizing it, it seems. Perhaps you just need more good old fashioned starvation - any volunteers among the environmental sensitive folks?

Look Deadbrain,,, have your nurse get with me so your computer time can be curtailed,,, you arent able to compete here with the lies and politics of falsehood,,, concerning global warming,,

"The U.S. Fish and Wildlife Service estimates that the polar bear population is currently at 20,000 to 25,000 bears, up from as low as 5,000-10,000 bears in the 1950s and 1960s. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain noted that the polar bear populations 'may now be near historic highs,'" it read.

J. Scott Armstrong of The Wharton School, University of Pennsylvania; Kesten C. Green of Business and Economic Forecasting, Monash University; and Willie Soon of Harvard-Smithsonian Center for Astrophysics, Cambridge, published their findings in 2008, arguing that the claims of declining population among polar bears are not based on scientific forecasting principles."

No they are based on simpleton minah birds,,, like you,, Awwwkkkk Global Warming, AWWWWKKK Bush Did it, AWWKKK the sky is falling,,,,,

your as full of shit as a christmass turkey.now if you are so stupid as to believe that ,just what would be your plan to stop it

the so called scientist who have been bought with fed grants and have been proven liars i would believe rush or bill before you or them

zpg movement is the obama care we are about enjoy .and as far as starving and death control i hope you and yours are the first to go you stupid ass.

Maybe you need to put down the Coolaid and learn something.
