At the end of March, Antarctic sea ice extent was the second highest on record, according to NSIDC, just 9000 sq km less than 2008. This is 23% greater than the 1981-2010 mean of 5.230 million sq km.

This maintains the trend of recent years, with six of the last seven above average.

 

Global Sea Ice

Meanwhile, global sea ice area is well above normal, running at 389,000 sq km above the 1979-2008 mean, as of 30th March.

The chart below gives a more detailed view of global sea ice anomalies since January 2013. Over this period, global sea ice has been above average for 252 days.

Antarctic Temperatures

 

Finally, it’s worth a look at the latest GISS temperatures anomalies for the Antarctic. Decidedly chilly!  (Notice, as well, the global anomaly for February – only 0.02C warmer than the 1981-2010 mean.)

    The Headline needs correcting to “Global Sea ICE Well Above Normal”.

    The word ice ought to be added to the title.

    The default map projection for NASA is the Robinson. When you start here
    http://data.giss.nasa.gov/gistemp/
    . . . then on the right side, click on the map (2nd image down).
    That brings up a grayed-in box with the Projection type listed as Robinson.
    There is a small black triangle there; click and select Polar Orthographic.
    Then, under that, click Make Map.

    With the Robinson projection, distortion close to the poles is severe but it is useful when the entire Earth is wanted on the graphic. When one’s interests are the polar regions then the Polar Orthographic is better.
