    Scientists say Arctic sea ice melting toward record
    By: Bob Weber, The Canadian Press

    Arctic sea ice is on track to recede to a record low this year, suggesting that northern waters free of summer ice are coming faster than anyone thought.

    The latest satellite data show ice coverage is equal to what it was in 2007, the lowest year on record, and is declining faster than it did that year.

    "Could we break another record this year? I think it's quite possible," said Mark Serreze of the National Snow and Ice Data Center in Boulder, Colo.

    "We are going to lose the summer sea-ice cover. We can't go back."

    EVERYONE knows how much hotter it feels to wear a black T-shirt, rather than a white one, on a warm day.

    In the same way, the melting of sea ice in the Arctic, revealing the dark water below, has been shown by Australian scientists to be the main cause of unusually rapid warming at the top of the world.

    Confirmation of this "feedback loop" means the region is likely to continue to warm strongly, with greater loss of sea ice and possible melting of the ice sheets.

    James Screen and Ian Simmonds, of the University of Melbourne, said the rise in surface temperatures in the Arctic in the past 20 years had been more than double the global average.

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

    Add to that methane, also a potent greenhouse gas, previously trapped below ice and now being released and we have another feedback loop at work. That's why the complaint that CO2 is such a small part of the atmosphere doesn't hold water. Like an amplifier on your stereo, a small change in the setting can have a big effect on the sound.

    I am sure the nuckle dragging Baggers on this board will come up with a good excuse for this one.

    What is the source of the second graph? Also, you are showing a rise of 0.5 for the Medivial Warm Period, which may have been correct for the Europe, but was not the case for the rest of the world. The Mann graph is for the whole world.

    So you graph comparison is apples and oranges. And dishonest, as you well know.

    The Arctic Ice had a big jump in March after tracking the same as 2007 for much of the winter. Unfortunetly, the coverage from that freeze is thin, and now the winds have pushed the thicker ice, what little there is left, east of Greenland, where it will rapidly melt.
