9 of every 10 weather stations fail to meet the National Weather Service’s own siting requirements

Is the U.S. Surface Temperature Record Reliable?  A two year study of 850 of the National Weather Service's 1221 climate monitoring stations reveal:

"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 ..."

The conclusion is inescapable: The U.S. temperature record is unreliable. And the U.S. record is thought to be "the best in the world."
