The average temperature in January 2011 was 30.0 F. This was -0.8 F cooler than the 1901-2000 (20th century) average, the 37th coolest January in 117 years. The temperature trend for the period of record (1895 to present) is 0.1 degrees Fahrenheit per decade.One data point does not a trend make, but this is not first bit of data we've had regarding global warming.

WSJ, editorial, February 10, 2011: The weather is not getting "weirder."
The Twentieth Century Reanalysis Project is the latest attempt to find out [whether weather is getting weirder], using super-computers to generate a dataset of global atmospheric circulation from 1871 to the present.So there.
As it happens, the project's initial findings, published last month [January, 2011], show no evidence of an intensifying weather trend. "In the climate models, the extremes get more extreme as we move into a doubled CO2 world in 100 years," atmospheric scientist Gilbert Compo, one of the researchers on the project, tells me from his office at the University of Colorado, Boulder. "So we were surprised that none of the three major indices of climate variability that we used show a trend of increased circulation going back to 1871."
In other words, researchers have yet to find evidence of more-extreme weather patterns over the period, contrary to what the models predict. "There's no data-driven answer yet to the question of how human activity has affected extreme weather," adds Roger Pielke Jr., another University of Colorado climate researcher.
I believe Al Gore would interpret this as absolute proof there is Global Warming!
