Sea Ice Extent – Day 34 – Antarctic Sawtooth

DataSouth / North

Normally (as you can see from the graph below) at this time of year Antarctic Sea Ice is high one or two years and then drops as much as 1.3 million sq km to a low (even a new) low and then repeats.

From 2012 the big drop in the sawtooth pattern stopped. From 2012 every  value is above every value before 2012 (with a little license for the tiny dip from 2012 to 2013).
