Temperature measurements that are the basis for claims of global warming are defective and wrong. That’s the finding of a scientific team led by Anthony Watts. Watts is a meteorologist, editor of “Watts Up With That,” founder of the “Surface Station Project,” and my personal hero for his style and bravado.
When global warming alarmists claim that the Earth is warming or that this was the hottest (year, month) ever, they are totaling up readings from rather simplistic, low-budget, small, automated weather stations scattered around the nation and the world. But about 90% of those weather stations violate the officially-published standards required for accurate measurements.
In 2007, meteorologist Anthony Watts stumbled onto an official weather station, where hot air was blowing onto the sensor from an air-conditioner’s exhaust, located on an asphalt parking lot heated by the sun.
Curious, Watts started the “Surface Station Project” to survey weather stations around the world. The “crowd sourced” response from trained scientists documented with photographs that about 90% of the weather stations are faulty. This sparked the “How Not to Measure Temperature” series highlighting individual faulty stations. Note that when Watts and his team refer to finding “siting issues” with the stations, you should read that as them discovering “royal screw ups.”
Watts was a presenter at the 9th International Conference on Climate Change (ICCC-9) organized by the Heartland Institute, held in Las Vegas, Nevada. Watts explained in a call in to our radio show, Conservative Commandos, from the conference on July 9, 2014, that a weather station (about the size of a modest camera tripod) standing next to a brick building will give inaccurate readings, because the brick building will radiate heat at night absorbed during the day. This raises the average temperature over 24 hours

They haven’t forgotten. Some have intentionally ignored it.
Global warming hoax bump for later...
Wow! That’s an awful lot of poor measurement error.
These measurements go back to the 1850s. Are you suggesting that the guys measuring the temperature in Siberia in the winter in 1875 were NOT calibrating their instruments to be accurate to within 0.1 deg? Are you suggesting we didn’t KNOW the daily temperatures in the Amazon rain forest with high precision in 1897?
Skeptic! Suggesting reputable scientists are taking measurements with a sledgehammer and reporting their results with a micrometer!
If you look at most professional level digital thermometers they are accurate to between +/- .08C degrees so anything more precise than that is impossible.
Here’s something that many are unaware of. Winter temperatures not far from some mountain tourist areas are often shown to be much higher than they really are. I’ve often seen weather service reported temps in my area as being 10 or 20 degrees (F) higher than local readings.
They do it for the tourism. Higher reported winter lows draw revenues. It’s highly likely that their are private-public
understandings, because the more business, the more revenues.
I’ve also seen quite a few improperly housed thermometers—structures collecting thermal. That can make a big difference under high-altitude sunlight.
