Climate reality keeps defying (mocking?) the IPCC's Climategate scientists. When examining the global temperature trends, it is clear that global warming has actually been missing for the last 15 years. This has definitely been the case of the continental U.S. as the graph on the left depicts.
This chart represents the 15 years (180 months), starting October 1, 1997 and ending September 30, 2011. Per the latest NOAA/NCDC U.S. official temperature data records, the 12-month period ending September was the 7th coldest September-ending period for the last 15 years. In terms of a single month, September 2011 was the 21st warmest since 1895 (September 1998 was the warmest.)
The per century cooling trend of this period, a minus 3.2°F, took place in spite of the huge warmth produced by two large El Niño events during this 15-year span: 1997-1998 and 2009-2010.
For the 10-year period ending September 2011 (October 1, 2001 thru September 30, 2011 - 120 months), the cooling trend accelerates to a very significant minus 9.9°F per century rate - again, per the updated NOAA/NCDC temperature records. These
