Presidential candidates Romney and Obama are at the forefront of pushing global warming hysteria, hoping to convince the public that more taxes, laws, regulations and micro-management are needed to make CO2-based fossil fuels more expensive and scarce. Both misguided aspirants are too in love with their fabricated beliefs to even pause to check what America's own climate agencies are reporting: the U.S. is cooling, not warming.
And, please note, not a single advisor, nor any of their climate science "experts" foresaw this lengthy cooling trend that is contrary to the "settled-science" warming predictions.
The above chart represents the 15 years (180 months), starting June 1, 1997 and ending May 31, 2011. Per the latest NOAA/NCDC U.S. temperature data records, the 12-month period ending May was the 4th coldest May-ending period for the last 15 years. In terms of a single month, May 2011 was 25th coldest May in the past 117 years.
The per century cooling trend of this period, a minus 3.8°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.
And what about "global warming" in Romney's home state of Massachusetts? Over the last 15 years ending May 2011, temperatures are cooling at a -2.6°F per century rate.
As for the 10-year period ending May 2011, the U.S. cooling trend accelerates to a very significant minus 13.1°F per century rate - again, per the updated NOAA/NCDC temperature records.
At some point, U.S. continental warming will resume, but the extended decade-plus long global cooling trend persists, contradicting the experts. None of the IPCC climate models, nor "consensus" experts predicted this cooling trend for the continental U.S.
