  1. I don’t see anything to get my undies in a bunch. Virtually every single Antarctic extent falls within 2 million sq km—three years ago, in 2014, it was on the opposite side of the interval at the record high daily extent. Since the bulk of Antarctic sea ice melts every year, no conclusion can be made about the variability and decline we’ve seen over the past two years.

    As far as the Arctic is concerned, it’s what, ~650,000 sq km below the median? Over 40+ years? Large declines have been the result of anticyclonic winds pushing thick, old ice through the Fram Strait and ice compression from sustained wind vortices towards the pole. It appears difficult to convince anyone that temperature increases have caused the ice not to form unless they’ve already drunk the global warming Kool-aid.
