From the Wall Street Journal:
What is happening to global temperatures in reality? The answer is: almost nothing for more than 10 years. Monthly values of the global temperature anomaly of the lower atmosphere, compiled at the University of Alabama from NASA satellite data, can be found at the website http://www.drroyspencer.com/latest-global-temperatures/. The latest (February 2012) monthly global temperature anomaly for the lower atmosphere was minus 0.12 degrees Celsius, slightly less than the average since the satellite record of temperatures began in 1979 …
Frustrated by the lack of computer-predicted warming over the past decade, some IPCC supporters have been claiming that “extreme weather” has become more common because of more CO2. But there is no hard evidence this is true. After an unusually cold winter in 2011 (December 2010-February 2011) the winter of 2012 was unusually warm in the continental United States. But the winter of 2012 was bitter in Europe, Asia and Alaska.
Weather conditions similar to 2012 occurred in the winter of 1942, when the U.S. Midwest was unusually warm, and when the Wehrmacht encountered the formidable forces of “General Frost” in a Russian winter not unlike the one Russians just had.
Large fluctuations from warm to cold winters have been the rule for the U.S., as one can see from records kept by the National Ocean and Atmospheric Administration, NOAA. For example, the winters of 1932 and 1934 were as warm as or warmer than the 2011-2012 one and the winter of 1936 was much colder.
As usual, read the whole thing.
In summary, historically the Earth has had much higher levels of CO2 than at present, but seemed to suffer no ill-effect; there is no evidence the Earth is getting substantially warmer; climate models predicting global warming have all failed, and failed miserably; and, there is no evidence that current outbreaks of extreme weather or either unusual or are the result of any hypothetical global warming.
