More Arctic Sea Ice

By

After two years of not much summer sea ice in the Arctic, levels now appear to be on the increase. See chart here.

    Probably explains why the Arctic is melting hey spanglers? Oh that’s right – the satellite doesn’t include that bit.

    If you look at the graphs on the International Arctic Research Center (in corporation with the Japan Aerospace Exploration Agency and the Advanced Earth Science and Technology Organization of Japan) you will see that arctic ice is growing

    Also some graphic photos from 13/10/2007 and 13/10/2008
show increase.

    How about your incorrect statement that the arctic ice is melting when in fact it is growing?
    Great fun, eh guys?

    Arctic ice growing – well let’s hope so – a thing called the boreal winter?

    Boreal Winter?
    Those two photos were taken on the same day – twelve months apart.

    Sigh …
    one finds an increased area now of first year ice – much less second and third year ice than 2007 – perhaps thin ice of some concern – hence the ice volume issue. Sigh….

    Well, look at that Ice volume graphs and note that “Sea Ice concentrations less than 30% are not displayed in these images.”

    I happened, by chance, to be talking in Thailand with a Danish researcher while we were at dinner. He was talking about ice cover in Greenland, and said that although there is thinning around the coastal strip, the thickness of ice on the plateau is increasing. He could not say whether there was a net increase or decrease in total ice coverage.

    Interesting.

    About a year ago, also by chance, I was talking with the owner of the only decent hotel in Greenland. He gets to talk with all of the researchers measuring and monitoring Greenland Ice. He said that the researchers were also of the same opinion.

    He also said that the Innuit were not worried about the current melting of the coastal strip, they had seen it before

    Looks like nature is doing its variable thing, as always.

    The amazing thing about Climate Change is that Climate is always changing. Perhaps that’s why it is called “Climate Change.”
