United States Is Getting Colder, Not Warmer

At Watts Up With That, data from the National Climatic Data Center are reviewed. The results are quite startling. Every region of the continental United States has shown a cooling trend during the winter from 2001 to the present, and five of the nine regions have also had a cooling trend during the summer. With respect to annual mean temperature, only one of nine regions–the Northeast–has gotten warmer; the other eight have gotten cooler.

This chart shows the overall trend for the period 2001 to 2010:

American data are significant because the U.S. is a large land mass, and because we probably have the world’s best records. But the absence of warming is a worldwide phenomenon. Pat Michaels:

“The last ten years of the BEST [worldwide] data indeed show no statistically significant warming trend, no matter how you slice and dice them”. He adds: “Both records are in reasonable agreement about the length of time without a significant warming trend. In the CRU record it is 15.0 years. In the University of Alabama MSU it is 13.9, and in the Remote Sensing Systems version of the MSU it is 15.6 years.

Finally, these two charts illustrate why no one who pays attention has any faith in the “data” produced by the alarmists. Both were produced by NASA’s Goddard Institute for Space Studies, which is run by Jim Hansen, one of the chief alarmists. Both purport to show data for the same area–continental U.S.–over the same period of time, 1880 to 1999. GISS produced the top version in 1999. Notice how the warming trend is subtle, and 1934 is significantly warmer than 1998. GISS produced the bottom chart in 2011. Note that the trend is completely different, and 1998 is now significantly warmer than 1934. Obviously, the data didn’t change between 1999 and 2001. Rather, Hansen and his colleagues continually come up with new ways to slice and dice the data to create the illusion of catastrophic warming when in fact there is none:

The good news is that hardly anyone believes these charlatans anymore.
