Sea Ice Update April 16 2014 – Antarctic Sea Ice is 66% Higher Than It Was in 1980

The most recent sea ice extent data for Antarctica is from April 15th and that is day 105.

Antarctic Sea Ice Extent for day 105 is 8.34885 million sq km.

In 1980,  Antarctic Sea Ice Extent for day 105 was 5.02921 million sq km.

That is a 66% increase.

If “climate scientists” were actually interested in science, you might think they would mention it.

Antarctic Sea Ice Extent Oscillation Pattern

I don’t know what it means, but I’ve been aware of an oscillation pattern in Antarctic Sea Ice Extent for some time. A week or two ago I made a slight change in one of my graphs to annotate the peaks and valleys with the year and now the pattern jumps out at you even more.

This graph is for day 95, but the pattern is similar in other parts of the year.

There has been since 1988 a  4 or 5 year oscillation where the ice extent goes to a valley in between peaks.  And the magnitude of the oscillation is growing.

These are not small oscillations. Sea Ice Extent as of today is 7,000,000 sq km.  The 2011 valley is 4,700,000 sq km. That is a 50% jump in sea ice on day 95 from 2011 to 2014.

I know the AMO has peaked and is poised to start down (it may take a few more years). But to repeat myself, I’m not sure what it means.

Antarctic Sea Ice Extent Update – 3rd Daily Record in a Row and 26th for the Year

On day 92, Antarctica Sea Ice Extent has been a daily record on 26 days. 92 out of 92 have been in the top 5. Of course the last daily record was only 630 sq km above 2008. Close, but still a record.

The following is all 92 days. A 1 is a daily record, a 2 is 2nd place etc. A . is lower than 9th. There are no . for Antarctica.
