The Remarkable Decline in Sea Ice

The turnaround in sea ice extent, both in Antarctica and globally, is remarkable. Yesterday's global sea ice extent was the lowest in the satellite record for Sept 14th:

with a current anomaly of -2.1 million km2.

Of course, this all may turn around at some point -- the Antarctic seems especially fickle.
