You have no doubt heard about how global temperature has risen dramatically over the last century.  But have you ever seen a definition of “global temperature?”  It’s measured through thousands of stations located throughout the world.  The continental United States itself has 1,221, and supposedly they are among the most reliable in the world. Has anyone undertaken to demonstrate the reliability of those readings?

Watts Up With That did, and here’s what they found:

We found stations located next to the exhaust fans of air conditioning units, surrounded by asphalt parking lots and roads, on blistering-hot rooftops, and near sidewalks and buildings that absorb and radiate heat. We found 68 stations located at wastewater treatment plants, where the process of waste digestion causes temperatures to be higher than in surrounding areas.

In fact, we found that 89 percent of the stations – nearly 9 of every 10 – fail to meet the National Weather Service’s own siting requirements that stations must be 30 meters (about 100 feet) or more away from an artificial heating or radiating/reflecting heat source. In other words, 9 of every 10 stations are likely reporting higher or rising temperatures because they are badly sited.

It gets worse. We observed that changes in the technology of temperature stations over time also has caused them to report a false warming trend. We found major gaps in the data record that were filled in with data from nearby sites, a practice that propagates and compounds errors. We found that adjustments to the data by both NOAA and another government agency, NASA, cause recent temperatures to look even higher.

The conclusion is inescapable: The U.S. temperature record is unreliable.

This project was done with 650 volunteers.  American Thinker has some thoughts:

While there is little dispute that the world had seen a small amount of warming over the last century, the question is whether the rise will accelerate due to greenhouse gases or whether the rise is just part of the natural variation in climate. In the past 10 years, it appears we are in a cooling phase. If the surface temperature record is biased on the high side, perhaps some of the observed warming is overstated.

These results also provide additional evidence that the science of global warming is not settled, and that we should not embark on a costly efforts to control CO2 emissions when the underlying data is faulty.

But the real question is why it took a dedicated group of volunteers to find the numerous faults in our temperature record rather than the heavily funded governmental and educational institutions which are continually warning us about global warming.
