Comparing 2001-2010 with 1981-2010 gives the following for each month:

January +0.37C
February +0.91C
March +0.58C
April +0.49c
May +0.29C
June +0.22C
July +0.37C
August +0.79C
Sepetember +0.38C
October +0.38C
November +0.78C
December -0.20C

You will notive that December is the only month that appears to be
getting cooler. All of the others are warming.

Clearly one very cold December will have more of an effect on the
2001-2010 mean than it will on the mean for a period three times as
long. If one argued that December 2010 was just one freak month, and so
compared the December means for 1981-2009 with 2001-2009, would there
still be a cooling trend?
