    From your article:

    <snip>

    So add the disappearance of Greanland's ice cap to the list of bogus “catastrophes” predicted by the global warming pundits, along with rising sea levels, higher temperatures, mass extinctions, and increased hurricane activity. In science, theories are judged by the accuracy with which they predict the behavior of nature. The eco-alarmists have been preaching widespread disaster for more than a quarter of a century and no disaster has occured. It's time to for scientists to start speaking up, as 650 climate scientists did recently at the UN global warming conference held in Pozan, Poland.

    Hmmm...... The first article, which you quote, Code, is a blog, obviously not by a scientists, totally filled with lies and half truths.

    The second citation just demostrates that Walleyes is incapable of understanding anything that he reads.

    High-resolution (&#8764;11 km) regional climate modeling shows total annual precipitation on the Greenland ice sheet for 1958&#8211;2007 to be up to 24% and surface mass balance up to 63% higher than previously thought. The largest differences occur in coastal southeast Greenland, where the much higher resolution facilitates capturing snow accumulation peaks that past five-fold coarser resolution regional climate models missed. The surface mass balance trend over the full 1958&#8211;2007 period reveals the classic pattern expected in a warming climate, with increased snowfall in the interior and enhanced runoff from the marginal ablation zone. In the period 1990&#8211;2007, total runoff increased significantly, 3% per year. The absolute increase in runoff is especially pronounced in the southeast, where several outlet glaciers have recently accelerated. This detailed knowledge of Greenland's surface mass balance provides the foundation for estimating and predicting the overall mass balance and freshwater discharge of the ice sheet.

    Greenland rapidly rising as ice melt continues

    Greenland Rapidly Rising as Ice Melt Continues
    ScienceDaily (May 18, 2010) &#8212; Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island--pressing down the land beneath and lowering its elevation. Now, scientists at the University of Miami say Greenland's ice is melting so quickly that the land underneath is rising at an accelerated pace.


    --------------------------------------------------------------------------------


    According to the study, some coastal areas are going up by nearly one inch per year and if current trends continue, that number could accelerate to as much as two inches per year by 2025, explains Tim Dixon, professor of geophysics at the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) and principal investigator of the study.

    "It's been known for several years that climate change is contributing to the melting of Greenland's ice sheet," Dixon says. "What's surprising, and a bit worrisome, is that the ice is melting so fast that we can actually see the land uplift in response," he says. "Even more surprising, the rise seems to be accelerating, implying that melting is accelerating

    NASA Finds Warmer Ocean Speeding Greenland Glacier Melt - NASA Jet Propulsion Laboratory

    February 16, 2010

    Glaciers in west Greenland are melting 100 times faster at their end points beneath the ocean than they are at their surfaces, according to a new NASA/university study published online Feb. 14 in Nature Geoscience. The results suggest this undersea melting caused by warmer ocean waters is playing an important, if not dominant, role in the current evolution of Greenland's glaciers, a factor that had previously been overlooked.

    Researchers Eric Rignot and Isabella Velicogna, both of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the University of California, Irvine; along with colleague Michele Koppes of the University of British Columbia, Vancouver, Canada, measured the undersea melting rates of four glaciers in central west Greenland in the summer of 2008. They deployed oceanographic equipment in the glacier fjords, sampling the water at various depths to measure ocean currents, temperature and salinity, along with the depth of the fjords. The researchers found the melt rates of the glaciers studied was 100 times larger under the ocean at their terminus points than that observed at the glacial surfaces.

    Rignot said the new study complements other recent research on the effects of ocean conditions in Greenland fjords. A study in the same online issue of Nature Geoscience by researcher Fiammetta Straneo of the Woods Hole Oceanographic Institution, Woods Hole, Mass., and colleagues looked at changes in oceanographic conditions in fjords that may be conducive to changes in undersea melting. Another 2008 Nature Geoscience study by researcher David Holland of New York University, New York, found that Greenland glaciers sped up as warm waters intruded into their fjords.

    Boy! That touched a nerve didn't it!:lol::lol: I havn't seen such a desperate attempt to baffle them with bullshit in a long time. And while it has been warm in parts of the world it has been far colder in more areas of the globe....or don't you read papers that report real news?

    I see. A dumbass blog against NASA and real papers from real scientists.

    By the way, why lie about the warm and cold record, Walleyes? Too easy to check;


    Interactive Weather Records Map, Stats, & Facts - Search for Weather Records in the US

    Weather records, tied or broken, from 1/1/2010 to 7/28/2010, for ALL States
    (All Records): 54341
    (H) High Temperature: 6772
    (HM) Highest Minimum Temperature: 10501
    (L) Low Temperature: 3620
    (LM) Lowest Maximum Temperature: 6479
    (R) Rain/Precipitation: 20890
    (S) Snow: 6079

    Warm (H + HM) Records: 31.8%
    Cold (L + LM) Records: 18.6%
    Precip. (R + S) Records: 49.6%

    Note the snow and rain events.

    One of the primary predictions of global warming is wide and wild swings in weather, with an overall warming.

    someone posted an article as "proof", but the article in question actually proved the opposite? Funny.
