Paul Homewood has blogged about a surprising admission from a paper published on the NOAA website.
They’ve admitted that if it gets colder in Antarctica there is more sea ice extent and when it is warmer there is less sea ice extent.
“this work not only debunks some of the fanciful arguments of warmists, it also suggests that temperatures in Antarctica have been falling since satellites started to monitor sea ice levels in 1979.”
Read about it here.
Antarctic Sea Extent has been running parallel to 2010 about 100,000 sq km below the record, but 890,000 sq km above the 30 year mean.
2013 (up to day 227) has averaged 760,000 sq km above the long term average, good for 2nd place to 2008 which averaged 810,000 sq km up to day 227.
Day 223 in the Antarctic (August 12) has Antarctic Sea Ice Extent slowly closing on 2010’s record.
Day 223 is 1,000,000 sq km above the 30 year mean.
Day 222 in the Antarctic (August 10) sees a big jump in sea ice extent as the climb rezooms!
Extent has climbed 290,000 sq km in the last two days and is approaching the 2010 records.
After taking a small jog sideways and downwards, Antarctic Sea Extent is back to moving up.
Day 221 is in 2nd place. 2010 holds the daily record. Can 2013 catch the 2010 record pace again? Wait and see.
Using the anomaly from the 1981-2010 mean for Arctic + Antarctic Sea Ice Extent here is the graph of the data since July 2012.
The global anomaly is pretty small right now, but it was pretty low in 2012 and almost 1,000,000 sq km earlier this year.
About average.
August 4 (Day 216) saw the 23rd Daily Record of the Year for Antarctic Sea Ice Extent. This is the 12th daily record in a row.
Day 216 Sea Ice Extent was 900,000 sq km higher than the 30 year mean.

Day 215 in the Antarctic was August 3 2013. By graphing all the previous day 215’s, you can see how much ice extent has grown in the last 30 years.
Sea Ice Extent is up 1,500,000 sq. km. from 1980 to 2013 and up 1,800,000 sq km from the lowest extent in 1986.
August 3 (Day 215) saw the 22nd Daily Record of the Year for Antarctic Sea Ice Extent. This is the 11th daily record in a row.
2013 is now closing in on the record for the 3rd and 4th number of daily records in a year (2006 and 2012).

Day 214 was 220,000 sq km higher than the previous record (which occurred in 2010). And it was 970,000 sq km higher than the 30 year mean.
