    Just a friendly and terrifying reminder that it’s currently WINTER in the southern hemisphere.

    Though I would like to see the data compared to other El Nino years.

    It’s been quite some time since I took stats, but wouldn’t six standard deviations put it in the true outlier category? If I’m even twenty percent correct in what I’m trying to communicate, that’s frightening.

      Been a while since I studied standard deviations but I remember 2 being already an outlier, 6 is a lot of deviation

      Person who does lots of stats checking in. That’s a good question. We usually refer to Sigma (1-sigma, 2-sigma… 6-sigma) as the probability that an observation could occur by random chance.

      The probability of 6-sigma occurring by random chance is about 1:1-billion.

      So you’re definitely right to characterize it as an outlier. In terms of sea-ice this means that based on our observations of ice extent recorded going back to 1989 (based on the image) it is extremely unlikely we would expect to observe a sea ice extent so far below the norm suggesting something else (climate change) explains the deviation.

    Ah yes, 1989. That’s when artic ice started, yep. Totally. I hear tell of the days of '88 when the lizard people in charge decided they needed a REALLY big freezer. Next year, boom. Artic ice.

    I’m really, REALLY tired of all this climate alarmism that ignores thousands of millions of years of history that we could study. Instead, sensationalists want to be heard more than they actually want to say anything and hyperfocus on the right now this second. Do you know how uncommon it is for the average person to know that were still in an iceage, geologically speaking?
