Arctic Sea Ice Extent is just skimming along the bottom of the one standard deviation from the 1981-2010 mean on day 309.

Sea Ice is 580,000 sq km below the mean. Which happens to be about 5.8% since the mean for the day is almost exactly 10 million sq km.

On this day in 2012 Sea Ice was 16% below the mean.

    • Good question. Glitches happen. Arctic Extent from NSIDC also shows a drop. Just less dramatic.
