    A lot less, despite (a) overlaying this year’s data at substantially higher magnification [seriously, just look at the coasts of Iceland and Scandivania!]; (b) the fact that it’s only 1st August and I strongly suspect the 1938 data represents the August average; (c) You’ve taken no account of this year’s low concentration values despite the fact that the 1938 map clearly distinguishes between open ice (70%) and unbroken ice (100%).

    To be honest, I’m struggling to see your point.

    Peter Ellis, any data before 1979 can be seen as somewhat inaccurate because reliable satellite record for objectively measuring ice began in 1979, so to compare any particular year before then is somewhat speculative, though that’s not to say the ice records before then were inaccurate. The main issue I have is AGW alarmist basing their BS off of the fact that we’ve lost ice since 1979, when they purposely don’t show the years before 1979 in the 1970s which had less ice.

    • Actually, there were excellent satellite records since the early 1970s – which NSIDC chooses to ignore.

      MFK Boulder:
      The satellite records are still not reliable enough to determine actual extent going back any number of years, because of improvements in measuring and evaluating techniques. They are not doing like comparisons. They only thing they have managed to show is Arctic ice changes extent from year to year depending on weather conditions in the area.
      For you and Pete in the cheep sheets I will repeat that temperature is a minor driver of ice conditions in the Arctic. There is evidence that more ice leaves the region during the coldest months of the year, because of wind conditions, than during the warmest.
      The Ice “Experts” are counting angels dancing on the head of a pin.

    I suppose that even if there are differences in methodology, the chart seems to indicate that loss of ice over 74 years, if any, is not catastrophic. The burden is on the alarmists to prove their case, because they claim we are headed toward a catastrophe and must take drastic, immediate action.

      Chicken Little always claims it is a catastrophe. They deny variable weather changes ice conditions constantly and we are not experiencing anything new.
