    What is your point? I calculated the average temperature for this year and a mean year using that graph.

    2010: 260,71 K
    mean: 259,38 K
    difference: 1,33 K

    If the global temperature has been raised about 0,8 K in 100 years. 1,33 K in 50 years is about 3 x faster.

    Here is my code


    procedure TForm1.CalculateButtonClick(Sender: TObject);
    var
    color: TColor;
    red, green: Integer;
    r, g: Integer;
    x, y: Integer;
    count: Integer;
    a, b: Single;
    begin
    red := 0;
    green := 0;
    count := 0;

    for x := 0 to Image.Picture.Bitmap.Width - 1 do
    begin
    r := 0;
    g := 0;

    for y := 0 to Image.Picture.Bitmap.Height - 1 do
    begin
    color := Image.Picture.Bitmap.Canvas.Pixels[x, y];

    if (color clWhite) and (color clBlack) and (color 16744448) then
    begin
    if (color = 255) and (r = 0) then
    r := y
    else if (color = 49152) and (g = 0) then
    g := y;
    end;
    end;

    if (r > 0) and (g > 0) then
    begin
    red := red + r;
    green := green + g;

    Inc(count);
    end;
    end;

    a := red/count;
    b := green/count;

    a := 280 - 10*a/74;
    b := 280 - 10*b/74;

    Memo.Lines.Add(Format('2010: %f K', [a]));
    Memo.Lines.Add(Format('mean: %f K', [b]));
    Memo.Lines.Add(Format('difference: %f K', [a - b]));
    end;

    • mt says:

      You should be find min/max y for the red and green pixels and average them. I think your code, because of the way bitmaps are stored in memory, is finding the highest value for each column of pixels. Since the current year temps have higher variability, your resulting current year temperature is likely too high.

      • You probably found just one flaw in a method that is likely inaccurate in other ways also. But Jussi claims he’s deduced something worth proving a point. To be more certain of things Jussi needs to look at the actual data. If he does he would find what Steven Goddard is finding.

      • Jussi says:

        I calculated the average of each column. It doesn’t change the temperatures much.

        2005: +2,16 C
        2006: +2,66 C
        2007: +2,34 C
        2008: +1,23 C
        2009: +2,18 C
        2010: +1,19 C

      • mt says:

        Turns out there’s one more issue, the code doesn’t filter the key. And there are missing data points where lines overlap, interpolation would be needed to fill in data. I also implemented this (without interpolation) and got very similar numbers.

        Unfortunately, DMI doesn’t seem to release their data in text format, so there’s no comparison to the “real data” available.

    Here are the four last year.

    2007
    2007: 261,67 K
    mean: 259,45 K
    difference: 2,22 K

    2008
    2008: 259,91 K
    mean: 258,72 K
    difference: 1,18 K

    2009
    2009: 260,69 K
    mean: 258,58 K
    difference: 2,11 K

    2010
    2010: 260,71 K
    mean: 259,38 K
    difference: 1,33 K

    This year is not complete yet. The difference will be about 1,5 K by end of year. Anyway the arctic is warming up much faster than the rest of globe.

  5. peterhodges says:

    ice melts at ~273k

    in fact, it must be melting like mad if the high anomaly shown on the map is correct!

  6. nofreewind says:

    Yes, that’s is some nifty calculation. But when you eyeball the graph during summer, when average temp is >273K it is obvious that during the summer, the high melt season, that it has been colder. Run those calculations on summer.

  7. nofreewind says:

    Even during that tipping point summer of 2007, for the days between June-September is it eyeball obvious that temperatures were not soaring, the fact is they were below average! Something else caused the ice to melt.

    • Sense Seeker says:

      My guess would be that at temperatures above freezing point, ice starts melting, which costs a lot of energy, so that temperature doesn’t rise much further until all the ice is gone. What else would melt the ice except heat, do you think?

      • Mike Davis says:

        Did in even start to enter your head that the ice was transported to warmer regions so it could melt rather than melt in place. Most of the polar researchers admit the loss of ice is due to ocean currents transporting the ice from the Arctic ocean into the Atlantic to melt.

  8. nofreewind says:

    The ice could be melting because of changes in heat from the ocean, from ocean currents or possibly undersea volancoes (not as likely IMHO). Then there is the wind and ocean currents which push the ice around. Arctic ice is very thin, so it could be very susceptible to currents, wind or ocean warming. It certainly does not look like from heat from above, nor a greenhouse effect.

    • Sense Seeker says:

      Could be, but if it is changes in the heat of the ocean, what causes that? That’s linked to the general global warming phenomenon – oceans and air exchange heat. Same for wind changes: what causes that?

      At any rate, the following snippet gives an impression of the arctic ice cover changes since 1979. Lighter colours are older sea ice – white is 10 years old.

      • Nothing unusual is happening in the Arctic. Your crowd cherry picked a time frame to make it look like alarming ice loss is happening. This is a usual ploy by you alarmists that are screaming bloody murder that the sky is falling because your chosen time period shows what you think is something unusual in Arctic ice. You could just as easily chosen a period that shows ice has been growing. But if you do that then you wouldn’t have any propaganda.

        You are completely predictable. You are going over ground that has been cherry picked and covered ad nauseum. You are a clone. By then it’s easier to be a thoughtless clone than to actually think. Congratulations for being tedious.

      • Sense Seeker

        Is Sense Seeker the only name you have used over the past year to post comments either here or at WaatsUpWithThat? Or have you used other names?

  9. It looks like the global warming crowd has to work very, very hard to make it look like the Arctic is warming. Because a warming Arctic is what James Hansen and Gavin Schmidt MUST have to justify their claim of a warmest year ever for 2010. They will be the lone rangers claiming it so they will be in an island. That island is a warming Arctic. So here is the hammering on the warming Arctic propaganda already happening before the announcement is made. They are laying the groundwork.

    My suggestion would be to visit Bob Tisdale’s website where one can get all the information necessary to understand ocean processes that affect weather and climate. That would include the Arctic.

    The South Atlantic feeds the North Atlantic, which in turn feeds the Eastern Arctic waters. Go look at whether the SA is warming or cooling. 🙂 The winds/current determine how and where and the ice is transported. Notice the NAO, which has been in it’s positive phase for several decades is now shifting to a negative phase.

    The Arctic is the exit door for global warming and the last refuge for AGW. It used to be Greenland was the ‘canary in the coal mine’, but that is a lost cause. There is nothing north of the Arctic, so as it starts it’s slow transition to cooling, the Antarctic will also move toward less cooling and the AGW movement will switch their storyline along with it.

    It seems I recall AGW dictates warming at the POLES, but the SP has been lost in the dust heap of failed AGW predictions. Of course we could always discuss the tropical lower troposphere “hot spot”, but that is something Warmologists wish would just go away too.

      That sounds about right. They cherry pick out what suits them best.
