Review Of 2013 – Global Sea Ice Area

January 3, 2014

By Paul Homewood


Continuing the review of 2013, let’s look at global sea ice.

Sceptics are often criticised for cherry picking, but it is hard to see how Dec 31st can be a “cherry picked day”!

Global sea ice area for Dec 31st 2013 was the highest ever for that day, on the satellite record going back to 1979.




And during the year as a whole, the global sea ice anomaly has been above average for most of the year. On average over the year, the area has been 104,000 sq km above the 1979-2008 mean, and was above average for 212 days.

    From what I can tell, the maximum global sea ice area for 2013 was the highest level since 1996. It occurred in early November.

      Was that the all time high?

      My figure is for the 31st December. The actual area goes up and down through the seasons, as Arctic and Antarctic ebb and flow.
      Therefore you cannot meaningfully compare different months.

        My intent was to point out the highest measurement for 2013 was higher than any level seen in 17 years.

    “Sceptics are often criticised for cherry picking, but it is hard to see how Dec 31st can be a “cherry picked day”!”

    How many other days have you reported on?

      Dec 31st is the last day of the year, if you had not worked it out. If I took one day at random, that would be cherry picking.

      Oh dear, lolwot.

      It’s not going your way, is it?

    The excuse that sea ice is expanding because the land ice is melting doesn’t pass either the sniff or laugh tests. When a glacier or ice sheet melts, it drains away from the bottom. Calving and shedding ice into the water is what glaciers do when they’re growing.

    The satellite record for the arctic actually begins in 1973 but at the time the sea-ice was much lower than today, It will be interesting to see if this data gets added again.

    The graph below is from the 1995 IPCC report.
