Antarctic Cold, Arctic Warm But Not Record

Arctic Sea Ice News and Analysis | Sea ice data updated daily with one-day lag:

It looks like the Warmists might do a report or two on ice melt in the Arctic, but if you look at the graphs, it is well less than 2012 and staying in the "standard deviation range".

The Antarctic would be another story though if these records were on the opposite side of what they are -- sea ice is possibly going to break an "all-time" high extent record (satellite observation, those are strongly weighted to the recent part of the last 100K years). This will not be due any coverage.

 "On July 1, Antarctic sea ice extent was at 16.16 million square kilometers (6.24 million square miles), or 1.37 million square kilometers (529,000 square miles) above the 1981 to 2010 average. More notably, sea ice extent on that date was 760,000 square kilometers (293,000 square miles) higher than the 2013 extent for the same day, and thus is on pace to possibly surpass the record high extent over the period of satellite observations that was recorded last September. 
For June, sea ice concentration and extent were higher than average for the Amundsen, Southern Indian Ocean, and far southern Atlantic (Weddell and eastward) sectors. (See Antarctic reference map.) The regions on either side of the Antarctic Peninsula were among the few sections with lower-than-average concentration and lower sea ice extent. 
Cooler-than-average ocean conditions are present near the ice edge along the Wilkes Land, Amundsen Sea, and Weddell Sea ice edge, which will favor continued expansion of sea ice in these areas.

Weather patterns over Antarctica during June were characterized by a strong low-pressure pattern over the Amundsen Sea, and lower-than-average air temperatures (1 to 6 degrees Celsius, or 2 to 11 degrees Fahrenheit below average) in the same region. Cool conditions (2 to 3 degrees Celsius or 4 to 5 degrees Fahrenheit below average) surrounded most of the coastal areas of the Antarctic, with the exception of the Peninsula region where, as has also been seen in the first two weeks of July, northerly winds brought warmer-than-average conditions and reduced sea ice extent.
