    The Greenland ice sheet is losing its mass faster than in previous years and making an increasing contribution to sea level rise, a study has confirmed.

    Published in the journal Science, it has also given scientists a clearer view of why the sheet is shrinking.

    The team used weather data, satellite readings and models of ice sheet behaviour to analyse the annual loss of 273 thousand million tonnes of ice.

    Melting of the entire sheet would raise sea levels globally by about 7m (20ft).

    For the period 2000-2008, melting Greenland ice raised sea levels by an average of about 0.46mm per year.

    If you multiply these numbers up it puts us well beyond the IPCC estimates for 2100.

    Since 2006, that has increased to 0.75mm per year.

    "Since 2000, there's clearly been an accelerating loss of mass [from the ice sheet]," said lead researcher Michiel van den Broeke from Utrecht University in the Netherlands.

    "But we've had three very warm summers, and that's enhanced the melt considerably.

    And what is the major cause of this, Chris?

    Well now. It ain't the sun. Solar minimum. It ain't the oceans. A strong and persistent La Nina during that period.

    But it just cannot be the GHGs. No, God forbid. People don't understand causation and coorelation. Throw some more fancy semantics and hacked e-mails out there, and that will restore the ice.

    And when the Artic Ocean Clathrates start outgassing, it just a natural process due to whales or something. Nothing to do with warmer water because of most of the North Polar Ice cap being gone. Nothing to do with the fact that the north draining rivers in both North America and Siberia are emptying significantly warmer waters into the Arctic Ocean.

    Ah well, going to be a fun show to watch.

    DO they have a Peer Reveiwed paper to back up this claim.....oh thats right we have found out that climate change activist scientists altered the peer reveiw process to exclude any studies that disagreed with their pre-determined man-made global warming stances.

    Shucks its too bad we dont have any CREDIBLE information that isn't just some news site

    Most of the world gets it, except for Fauxnews and Senator Foghorn Leghorn from Swamptown, Oklahoma.

    most of the world is laughing at you.

    those who aren't are being investigated for academic fraud or having inconvenient scheduling conflicts.

    enjoy.
