Is Greenland showing signs of melting?

I see a lot of things posted about this on various web sites that seem very contradictory. Is it retreating or expanding.

Update:

James E: sorry i'm not interested in rubbish blogs like iceagenow.

M of laughlin: Funny how the first two knew what I was asking but if you must be perdantic then Is the frozen H2O sitting on top of Greenland showing signs of melting.

    According to measurements by the GRACE satellite, Greenland's total ice mass declined by 84+/-28km^3 (about 75bn tonnes) per year between 2000 and 2004.

    Research in 2002 found that it was losing mass:

    Here's papers:

    http://polarmet.mps.ohio-state.edu/jbox/pubs/Box_e...

    I picked these at random from the first page of a googlescholar search.

    Warmer temperatures are leading to higher precipitation which is thickening the centre, but also leading to more melting. In Greenland, melting is the dominant effect and it is losing mass overall.

    EDIT: Jonnie B, according to the HadCRUT3 global temperature record:

    http://www.cru.uea.ac.uk/cru/data/temperature/hadc...

    This year is currently ranked 9th warmest on record, and is warmer globally than any year before 1998. This is despite us being in a solar minimum, and at a minimum of pacific warm cycles.

    No. "Interpretation of ice middle and clam shell documents ability that between 800 and 1300 advert the areas around the fjords of southern Greenland experienced a quite mild climate quite a few ranges Celsius greater than conventional interior the North Atlantic,[17] with timber and herbaceous vegetation transforming into and cattle being farmed. Barley became grown as a crop as much as the seventieth parallel.[18] what's verifiable is that the ice cores point out Greenland has experienced dramatic temperature shifts many situations over the final one hundred,000 years."

    From what I understand, parts of the Greenland glaciers are melting while other sides of it are expanding. What you have to wonder is what did Greenland look like when the Norse settled it and lived their for about 300 years?

    Sorry Guys but what I hear is it is one of the coldest years. The upper US is also seeing it , like Denver just had a snow of 3 ft. And high winds that gave snow drifts of 10 ft.The oceans are not rising because ice occupies more space than watter.There are several errors in the theory ,study till U understand.

    Greenland is not melting. The ice covering Greenland may be melting.

    Perhaps if there was tremendous geothermal activity Greenland could 'melt'. Though usually this causes an explosion; think Krakatoa (east of Java).

    It sure would be nice if Greenland did a little melting, but that's not likely to happen.

    Sunspots still zero... forecast:cold.

    Here are a couple of more reasonable scientific explanations of what is happening as against the politically motivated alarmist statements in the media.
