Location Issues

(Fox News) - If you've ever wondered how climate scientists come up with their figures to prove global warming, there is a network of 1,221 weather stations used by the National Oceanic Atmospheric Administration in the U.S.

But now former TV meteorologist Anthony Watts is finding some of those thermometers may not be located in places showing the most accurate readings.

The Pittsburgh Tribune Review reports a preliminary look at the system finds a weather station in Forest Grove, Oregon, 10 feet from an air conditioning exhaust vent, another in Tahoe, California, next to a drum where trash is burned and one in Roseburg, Oregon, on a rooftop near an air conditioning unit.
