Painful contortions from the alarmists at the National Snow and Ice Data Center

"An expected paradox: Autumn warmth and ice growth"
As is normal for this time of year, ice extent increased rapidly through most of October. However, this year, the increase was particularly fast, which contributed to above-average air temperatures near the surface. A look back at the entire melt season from March through October reveals that the Arctic sea ice is showing some unusual changes in growth and melt cycles.
...
October ice extent was 0.89 million square kilometers (0.34 million square miles) less than for the 1979 to 2000 average, but 1.63 million square kilometers (0.63 million square miles) greater than for October 2007.
...
At its fastest point on October 15, the 2008 ice growth exceeded the 2007 growth rate on the same date by 92,000 square kilometers (36,000 square miles) per day. The near-record daily growth rate slowed toward the end of the month and has now fallen below the 2007 growth rate. It is important to reiterate this fast rate of growth is not unexpected under current conditions.
...
Arctic sea ice and climate are behaving in ways not seen before in the satellite record—both in the rate and extent of ice loss during the spring and summer, and in the record ice growth rates and increased Arctic air heating during the fall and winter.
