WUWT Arctic September Average Sea Ice Prediction submitted to ARCUS

Here are the numbers from the poll started yesterday. 657 votes were cast on the question “What will the September monthly average Arctic sea ice extent be? “and the breakdown is shown below.


The top 5 vote getters, garnering 55% of the vote, were averaged using a weighted average calculator. The results are below.


The value submitted to ARCUS is 5.6 million square kilometers for the September average sea ice extent.

  1. I am still confused as to which metric this refers. Is this the 15% JAXA or the 30% DMI? Or some other one?

  2. who cares which netric, this is about a return to sanity and folk stepping off the CAGW “gravy train” which is slowing to a crawl..

  3. this gives a good example of how an “average” is found and what it really says…..the average here was NOT in the top 5 responses……when you take an average you will find almost NOBODY fits that “average” almost every person differs from the average in many ways…………this is also a problem with stereotypes and how people use them, to become a stereotype there has to be a big element of truth in it BUT just like an average it CANT be applied to any individual in the group stereotype.

  4. I did not vote because I think the actual outcome is too dependent on manipulation. As I’ve posted before, the satellite operators can trade off ice area between the Arctic and the Antarctic depending how they orient the polarizer, or its software equivalent. I don’t want to predict what they are going to do.

  5. In comment to the averaging method used by WUWT, it is curious that the “5.6M” bin was not counted because it wasn’t in the top 5, even though it is in the range of the responses which *were* counted. Perhaps the “top 5” could set the bounds of the counting range, that is, in this case 5.3M was the low end and 5.8M was the high end, so all responses in this range could be counted. Oh well, not important.

  6. Half-way through the charts I just lost focus and started wondering why Rob Lowe hasn’t aged.
    sorry no mock intended.

  7. Markpro3ger, it is the average of the entire month of September not just the low point. But I too agree 5.8 seems like wishful thinking. I was one of those that picked 5.3 and I think the low point will be just under 5.

    The mode — peak response — would be of interest, too.”
    The mean of all the entries was 5.6, the median was also 5.6 and the mode was 5.8

  9. markpro3ger your missing something – I heard that al gore was going to visit the artic in September so that is why I picked 6.0….we’ll see

  10. Interesting, I picked 5.6, was sorry to see it way off the top on the numerical votes tally, but then, it was calculated as the average of the top choices. WIN!

    “since with JAXA we are already at 6.1 million square miles…why was anyone predicting 5.8 million? that’s like 4 respectable melt days and we have a good 4 weeks left of melting….Am I missing something?”
    If I’m correct about whose numbers should be used, yes you are missing something. JAXA and NSIDC numbers are not directly comparable, even though both claim to measure 15% extent, because of how the data is processed. For example, as of my typing this, JAXA is reporting 6.05 million km2, while NSIDC is reporting 6.47 million km2.
    Also, as was already pointed out, the prediction being asked for is not for daily minimum, but for the September average.
    Even keeping both of those facts in mind, I’d still say that 5.8 is overly optimistic.
