  1. I heard the ice re-froze-big time. It ebbs, it flows…

    The trend is unmistakable–downwards.

  3. There is a big difference between annual ice (which re-freezes every winter) and multi-year pack ice. The latter has been steadily receding, and now at a much faster rate than climatologists predicted. Without the multi-year ice pack, more solar radiation (heat) is absorbed by the ocean, leading to faster warming, than when/where ice reflects much of that radiation.
