Antarctic Sea Ice Extent 1.15 million sq km Above 2013

Published on by sunshinehours12 Comments

So far in 2014, Antarctic Sea Ice Extent is 1.15 million sq km above 2013 and 1.54 million sq km above the 1981-2010 mean.

More remarkably it is only 400,000 sq km below the extraordinary high extent that occurred at a similar period in 2008.

Extent has been more than two standard deviations above the mean since Dec 26 2013 and one standard deviation above the mean since May 29 2013.

Global Sea Ice Extent Stats For 2013

Published on by sunshinehours14 Comments

2013 was an average year for Global Sea Ice Extent (thanks to it being a banner year for Antarctic Sea Ice Extent)

The average daily anomaly  was 200,000 sq km above the 1981-2010 mean. That would be 15th highest since 1979.

Max Extent of 27.4959 million sq km For Whole Year Occurred On Day: 306 November 2
Max Anomaly For Whole Year Occurred On Day: 353 December 19 = 0.9459423  million sq km
Max Anomaly % For Whole Year Occurred On Day: 73 March 14 = 4.72%

There were zero daily records set and no 2nd places.

Here are the key stats for each year. Min/Max/Anomaly in millions sq km.

Antarctic Sea Ice Extent Stats For 2013

Published on by sunshinehours13 Comments

2013 was a banner year for Antarctic Sea Ice Extent. I enjoy my small role in publicizing this data because the “climate science” profession prefers to ignore Antarctic Sea Ice. Of course it is a little harder for the MSM to ignore Antarctica this year when a ship of “scientists” searching for publicity about lower sea ice caused by “global warming” get stuck in the ice.

The highest maximum for Antarctic Sea Ice Extent of all time was set on October 1st 2013.

The highest average anomaly for a year occurred in 2013. 2013 averaged 850,000 sq km above the 1981-2010 mean.

In 2013, the highest extent ever in each month occurred in July, August, September, October and November.

2013 now has the 2nd highest number of daily records (behind 2008).  2013 also has by far the most “Top 2” days in a year. Only 1979 is left in the list of daily records from before 2000.

Year First Second Top 2
2013 108 149 257

Antarctic Sea Ice Extent is 1.5 million sq km above the 1981-2010 mean. Thats almost 15% higher.

The mean for the day is 10.25 million sq km and the most recent day’s data is 11.78 million sq km.

After a few days of being in 3rd place Antarctic Sea Ice Extent is now back in 2nd place.

2nd Daily Record in a Row Antarctic Sea Ice Extent – 107th For 2013

Published on by sunshinehours15 Comments

Day 342 and 343 (Dec 8th/9th) were daily records for Antarctic Sea Ice Extent. That makes them the 106th and 107th records for 2013.

2008 still leads with 122 daily records. 2013 does have 244 1st and 2nd place finishes for in front of 2008 with 160 1st and 2nds.

2013 will probably only set 2 or 3 more records before the records set in 2007 prevent any more.
