The usual concern for Arctic sea ice crops up in the summertime, when the frightening ice decline results in more open water, and therefore a greater capacity for the dark Arctic Ocean to absorb the 24-hour sun’s heat - rather than reflect it back into space, as was the case when most of the Arctic surface was covered with bright, white ice.
But look at the state of Arctic ice now. Even as we approach the usual winter maximum, the ice extent is lower than at any time in recorded history, according to the National Snow and Ice Data Center in Boulder, Colorado. The Polar Science Center in Seattle reports that ice volume also continues its decline, or should I say, collapse  - at unprecedented speed, to unprecedented lows.
Thus, despite the calls from d’oh-headed deniers like Art Horn  for a global chill driven by a “super La Nina,” we have a year that wraps up tied as the warmest ever  and a continuing trend that indicates the coming summer will feature the effects of redoubling climate feedbacks.
We stand in awe of the DenierGang’s ability to tie themselves up in logical knots and we await their next falacious analysis with unfailing interest.
