The blue and green stations are the good ones.
Global warming projections of a few tenths of a degree C are made with 91% of the stations in error by more the one degree C.

“... 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.”
I remember seeing a weather station at the University of Oklahoma that was next to a building.
Skewed and falsified data as a part of a conspiracy and fraud imposed on the entire world have been revealed for the hoax that it is.
Reality has a most nasty habit of coming around and biting the manipulators of fact in the Gluteus Maximus in a most painful way.
Some 95% of the personal woe in this world turns out to be self-induced. The woe these pranksters are now suffering does not gain my sympathy.
One of my favorite stories to tell over this topic. In the early 1990s....I was a avid jogger while based in Tucson, AZ. I used to jog the whole block around Reid Park on the southern side of Tucson, roughly a three-mile run.
At the end, where 22nd Street and South Alvernon Way meet....it’s a four-way street on both avenues. ALL asphalt. About seventy-five feet away from that corner, on a pile of bedrocks is a concrete platform for an official weather station trailer. It’s got an air conditioner on one corner of it and at least ten different measuring devices for wind, temperature, rain, etc. The temperature gauge, based on my best guess is within four feet of the air conditioner.
Between the asphalt, the rocks, the concrete, the AC unit’s hot air, the aluminium trailer itself....I’d guess the temperature reading to be a minimum of three degrees higher than what it ought to be if it were two hundred feet away just on regular grass or sand.
Accurate readings? No....whoever put it at this corner....had zero knowledge of proper positioning. It was a national weather service property, and I’d question if they knew anything about their supposed career study area. I’m not a rocket scientist....but this would have been the absolutely wrong place to place it, unless your agenda was to show continued high temperatures for this area of Tucson, for some special purpose.
I admit....Tucson is extra hot in the summer. But the plain truth is....it’s listed on the national news from that Reid Park site, and that temperature is really three-to-five degrees higher than it really is.

One of the first things you learn in a higher education science curriculum is the topic of “significant digits”
It is a tough concept to grasp for some, but it basically means you cannot have more accuracy than your measuring device.
If all you have is a yardstick, it is impossible to tell me how long something is to a thousandth of an inch. You could tell me something is a yard and a half or 2ft. 3and 1/2 inches (if your yardstick is marked to inches), but you cannot tell me something is 3.0005 inches.
Similarly, if all you have for hundreds of years of temperature data is tree rings and ice cores, you cannot tell me temperature has risen 0.06 degrees.
And that is the claim of the global warming religious zealots- temperatures went up 0.06 degrees. I knew that was bull$hit the first time i saw such accuracy depicted.
This is a tool to achieve a political agenda, and nothing else.
I think a huge problem is that just like the airport examples, a well sited station can change if asphalt and building are built around it over the years. That makes the time-series have a trend not due to carbon dioxide or really any change in climate.
This was reported a few years ago, that most (99%) of all temp sensors are located where they are affected by higher temps, such as being located over pavement, near air conditioner heat exchangers, and on top of buildings.
If these so-called 'environmental scientists' don't understand basic research methods, we need to STOP referring to them as 'scientists'... It would be a start.
Global warming hoax bump for later...
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.
