Sea Ice Extent – Day 85 – Global Sea Ice Above ‘Normal’ – Antarctica Above 2 Standard Deviations

Global Sea Ice is above the 1981-2010 mean.

Antarctica is 2 standard deviations above the mean and has been for the last 10 days – and 49 days in total so far in 2015. In January there were 18 days 3 STD above.

The Arctic is only 98,000 sq km below the ‘maximum’ for 2015 which I called on day 53 (which may still turn out to be wrong). (See bottom graph for last 40 days)

Sea Ice Extent – Day 79 – Global Sea Ice Above ‘Normal’ – Antarctic 2nd Highest and Approaching Daily Records Again

 

Global Sea Ice is now above the mean.

Antarctic Sea Ice set 20 daily records earlier in the year and it looks like more may be set.

Sea Ice Extent – Day 75 – Maybe Not A Record Low Arctic Maximum

Back on March 10th (which was actually day 68)  I called the Arctic Maximum at 14.595 million sq km. to have occurred on day 53.

From day 53 to day 68 extent had fallen over 300,000 sq km.

Since then Arctic Sea Ice Extent has risen 200,000 sq km to 14.427 million sq km.

Maybe I called it too soon. Maybe not. 1995 and 2010 had late maximums which occurred on day 90. It is only day 75.

Sea Ice Extent – Day 74 – Global Sea Ice Identical To 1981

On Day 74 in 1981 Global Sea Ice was 19.1 million sq km. In 2015 on the same day Global Sea Ice was 19.1 million
