Yes, Antarctic sea ice extent is at record lows right now for it's date, but its trend is still very much upward. Which lately some people (ie. Chris Mooney, who has been an exaggerating hyper-alarmist his entire career -- here for November -- while being utterly ignorant of basic physics) wants to overlook the long-term trend for short-term results. Don't we castigate deniers for the same every day of the year(?):
Maybe there is some tipping point. I haven't seen anyone explain that -- have you?
Otherwise Antarctic sea ice is going to have a statistically signifant positive trend for a very long time.
