USA temperature increase being inflated...
In a new study, just released by Dr. R. Long, increases in USA temperatures are being "over-inflated" by the National Climatic Data Center. When Dr. Long used RAW data and compared temperatures from the start of the 1900's to now, he found a large difference in urban and rural sites, due to the "heat island effect".
It has been my contention for a long time, that rises in recorded temperatures have been polluted by thermometers that are being impacted by quickly growing urban centers. San Antonio is a perfect example...our official thermometer is located on the runway of our international airport. Not only is there a lot of concrete from the runways, but San Antonio International is surrounded by two major highways (Loop 410 and Hwy 281) and large streets, such as Broadway, Wetmore and Bitters.
In a nutshell, rural temperatures have changed very little over the past 100 years.
