Mid-March sees the Arctic Sea Ice Extent peak for the winter and begin
its descent. I was delighted to see the little blue line venture into
the grey band that marks two standard deviations from the 1979-2000
mean, for the first time in recent memory. I may obsess about sea ice
a bit; this daily graphic is my home screen.
