The NOAA / NCDC climate research group published year-end U.S. temperature data confirming that U.S. is still cooling - CO2 has zero global warming impact on U.S.
As the Climategate 2.0 emails continue to establish, the alarmist climate scientists claiming "unprecedented" and "accelerating" global warming actually can't find either. 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 chart below depicts. (click on to enlarge)
This "global cooling" of the U.S continues in spite of growing CO2 emissions. Human CO2 emissions continue to grow at a business-as-usual pace with a record set in 2010 for the largest emissions ever.
The NOAA/NCDC chart on the left represents the 15 years (180 months), starting January 1, 1997 and ending December 31, 2011. Per these latest U.S. official temperature data records, the 12-month period ending December was the 5th coldest December-ending period for the last 15 years.
In terms of a single month, December 2011 was the 22nd warmest since 1895 (December 1998 was the warmest).
The per century cooling trend of this period, a minus 4.4°F, took place despite 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 December 2011 (Januart 1, 2002 thru December, 2011 - 120 months), the cooling trend accelerates to a very significant minus 7.2°F per century rate - again, per the updated NOAA/NCDC temperature records.
Please note: The linear temperature trend, as shown in the NOAA chart, is not a prediction.
