The story of sea ice in the “other” Arctic, the Antarctic, seems to be largely untold. It turns out the extent of the Antarctic sea ice sheet has reached a record high. At least it is a record since satellite measurements began in 1979. Yes, I know, that is a short period and so not much of a record, but it is the same period that is used as the basis for Arctic sea ice record claims. Similarly, consistency requires that if one claims that Arctic ice has trended down then one must admit that Antarctic sea ice has trended up.
