After a few days of shrinking, Antarctic Sea Ice Area is growing again.
Month: September 2012
NOAA Temperature Trends Per State as low as -249.5F / decade
Using data as of Aug 2012, these are the NOAA temperature trends (in Fahrenheit per decade) 6 months ago to present, one year to present etc. (Of course the NOAA data may be heavily adjusted upwards)
Notice the 6 month trends for most states are amazingly low such as Iowa’s -249.5F / decade, which of course was caused by the very unusual warmth in March 2012.
But if you look all the way to the right at the 15 year trends, even with March 2012 being so warm, there are still 20 states with a negative trend.
And then looking at the 6 month trends that are hugely positive like Washington and Oregon caused by a very warm August.

Arctic Ice Compared to AMO
I am not a graphics wizard, but I took the Arctic Ice image from NSIDC, and graphed the AMO.
And then I flipped the AMO. Looks like AMO has an effect on Arctic Sea Ice.
1934 as Art (NOAA data)
Here is 1934 graphed using data from NOAA (continental 48 states). One line per state. Each months anomaly from the 1895 – 2012 average for each state. Click on it for a larger version.
Notice how each month there are dozens of states temperature moving in the same direction, but there are large numbers of states going in the opposite direction.
Notice how one month into 1934, half the states were -10 to -14F colder than the long term average and others were over 5F above normal.
Antarctic Sea Ice – A record for the day
Antarctic Sea Ice area is still at a record amount for day 260. Using the data from Cryosphere I have graphed the record breaking Antarctic Sea Ice data.
Highlighted are 2012, 2007 and the median for 1979-2008.
Antarctic Sea Ice Area – 5th Highest Ever – Day 259
Update: I’ve added the 10 years with the lowest amount of Antarctic Sea Ice on day 259 at the bottom.
Antarctic Sea Ice is at it’s 5th highest amount ever on day 259. Using the data from Cryosphere I have graphed the record breaking Antarctic Sea Ice data. It is the most Antarctic Sea Ice ever for day 259, but it soon may break the all time satellite record that occurred in 2007. Highlighted are 2012, 2007 and the median for 1979-2008.

Great Arctic Cyclone 2012 Caused the Record Low
Update: Watch a NASA simulation of the cyclone breaking up the ice.
The Great Arctic Cyclone of 2012 hit on Aug 5 and passed over the North Pole on Aug 6.
“An unusually strong storm formed off the coast of Alaska on Aug. 5, then moved over the central Arctic. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite took the images that make up the mosaic during various passes over the North Pole on Aug. 6, when the storm was swirling over the middle of the Arctic Ocean. According to a NASA statement, there have only been about eight storms of similar strength during the month of August in the last 34 years of satellite records.
Using Jaxa data, note that from July 20 all the way to Aug 5, Arctic Sea Ice area was higher than in 2007. The peak day was Aug 5th, when 2012 was 229,062 sq km more than 2007.
Once the Cyclone hit, the ice broke and melted. It isn’t the apocalypse in the Arctic. It was weather!
