    New Melt Record for Greenland Ice Sheet; 'Exceptional' Season Stretched Up to 50 Days Longer Than Average

    ScienceDaily (Jan. 21, 2011) — New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades.


    "This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average," said Dr. Marco Tedesco, director of the Cryospheric Processes Laboratory at The City College of New York (CCNY -- CUNY), who is leading a project studying variables that affect ice sheet melting.

    "Melting in 2010 started exceptionally early at the end of April and ended quite late in mid- September."

    The study, with different aspects sponsored by World Wildlife Fund (WWF), the National Science Foundation and NASA, examined surface temperature anomalies over the Greenland ice sheet surface, as well as estimates of surface melting from satellite data, ground observations and models.

    In an article published in Environmental Research Letters, Professor Tedesco and co-authors note that in 2010, summer temperatures up to 3C above the average were combined with reduced snowfall.

    The capital of Greenland, Nuuk, had the warmest spring and summer since records began in 1873.

    Bare ice was exposed earlier than the average and longer than previous years, contributing to the extreme record.

    "Bare ice is much darker than snow and absorbs more solar radiation," said Professor Tedesco. "Other ice melting feedback loops that we are examining include the impact of lakes on the glacial surface, of dust and soot deposited over the ice sheet and how surface meltwater affects the flow of the ice toward the ocean."

    WWF climate specialist Dr. Martin Sommerkorn said "Sea level rise is expected to top 1 metre by 2100, largely due to melting from ice sheets. And it will not stop there -- the longer we take to limit greenhouse gas production, the more melting and water level rise will continue."

    Dr. Tedesco's continuing research on ice sheets can be followed on Cryocity.org.

    Greenland’s Ice Feels the Heat in Record-Setting 2010

    Unusually warm conditions in much of the country helped extend the annual melting season by up to 50 days longer in 2010 than the average observed between 1979 and 2009, researchers found. ……………
    Recent studies suggest that sea level will rise between 3 and 6 feet by 2100, with a significant contribution coming from the more rapid melting of huge ice sheets in Antarctica and Greenland.

    Trust me.........nobody cares.


    Especially people in Minnesota who will be enjoying temperatures of minus 40 degrees tomorrow and through the weekend.

    jackass duped alarmist k00ks...............:fu::boobies::fu::boobies::fu::boobies::fu::boobies::fu:



    Anyway...........Antarctic ice has reached near historic levels in the last year.

    k00k morons...........like ten years ago, still cherry picking their data to attain their agenda!!!!



    fcukking............fAiL

    An extriordinery winter shaping up in Northeastern Canada and Western Greenland.

    Hudson Bay Region Still Waiting for Winter

    Dec 30, 2010; 5:41 PM ET

    Much of northeastern Canada is still waiting for winter to set in, and the latest projections continue to show more abnormal warmth across the region into early January.

    Persistent high pressure in the upper levels of the atmosphere over the region has prevented any Arctic air from getting into the region since autumn. Basically, an island of unusually warm air.


    Temperature anomaly map for Canada in November 2010.



    The impact of this cannot be good for the locals and the wildlife up in that region.

    This long spell of warm weather has even prevented a large part of eastern Hudson Bay from freezing over, and it's almost Jan. 1!

    GFS model forecast for temperature anomalies across North America on Jan. 13. Reds are warmer than normal, blues colder than normal.



    The image below is from MODIS and still shows a large body of open water along the eastern side of Hudson Bay which is almost unheard of.

    Well, dumbass, you started with Minnesota. Last time I looked that was in North America. So Minnesota is cold in January. Break out the headlines. The present tempertures in Minnesota is normal for Minnesota in January. The present tempertures for Hudson's Bay and Greenland are far above normal for January.

    And the sea ice anamoly in Antarctica is in the minus column. Do I need to explain to you what an anamoly is?
