|Fig. 1 Arctic Sea Ice Extent Acceleration?|
When I first noticed it a few days ago, only the tiny beginning of the sharp downward-to-the-right line was visible.
It was shaped like the peak of a roof at that time.
It continued for a couple of days, so I wondered if the satellite had another failure as it had twice before (once in 2009 and again a few years ago; they found a work-around both times).
I waited until there was an upward change in direction, then waited until today, thinking that maybe this is real and not an equipment failure.
I can't tell from the pictures of the ice that anything catastrophic has happened, so I stopped thinking that it might have been the radical change in the Beaufort Gyre scientists have been waiting for (Mysterious Zones of The Arctic, 2, 3).
