Almost all of the claimed warming in Nevada is due to urban heat island effects at Las Vegas, and the recent addition of hot desert stations like Laughlin.
Disrupting the Borg is expensive and time consuming!

“DRAT!!! Wrong again!!!” Mike Mann was overheard whining.
Why? 1) LV’s population rose about 85x between 1950 and the present. 2) MILLIONS of people moved TO LV even though Las Vegas warmed 10+F over the span of its temp. chart. 10+F is 3x the temperature change “Dr.” Mann + other alarmists warn will cause mass extinctions (as in the Extinction Rebellion).
And with the increase in population,size and thousands of tons more of concrete and asphalt(the SeaQuest is said to have 2 million visitors per year – lots of parking lots needed) as heat absorbers one can not really expect different results.
I also remember watching a documentary a few years ago about arab countries planning to built cities in a more asymmetrical way as they said that a symetrical built lets cities heat up faster –
and Las Vegas is as symetric as a city can be.
Long straight street whereever you look.
A number of years back I recall that a guy from University of Toronto (CA) went through the records for North American Thermometer Placement. I do not remember the details, but he claimed that a rather high number of official thermometers were ill-placed. He mentioned some real choice ones: On a south facing rock face; next to a burn barrel; next to the tarmac at an airport; etc.
The question is this: Was this purposeful to inflate warming numbers? I would not doubt it.
I believe it was Ross McKitrick, an economist and statistician, who noticed that thermometers placed a few kilometres apart had substantially different readings. I believe Dr Willie Soon produced a temperature plot ignoring the badly-sited thermometers. Not only did the warming disappear, but the results correlated well with ocean temperatures over the same period, which the original measurements did not.
This was data adjustment based on sound physics, not fiddled to fit model predictions like the climate fraudsters.
We found one here KY that was on an asphalt parking lot, next to the South Side of the building and placed right next to an AC UNIT?
I participated in Anthony Watts’s Surface Stations project a number of years ago. My favorite misplaced station was in a guy’s yard in Condon, Oregon, where the recorded temperature had skyrocketed in recent years. Condon is in north central Oregon, where it can get pretty darn hot.
The weather station was right up against his deck and house on the south side of the structure, in full sun. He told me that in prior years it had been about 50 feet away in his garden, but “someone from the government” came and moved it close to his house. He didn’t know why.
Well, no wonder!
Damning.
There are many improperly placed weather stations. However the weather stations adjacent runways and taxiways at airports are not among the “bad placement” narrative. Those at airports are there for the purpose of aviation safety, as it is imperative for airliners and small planes to know the exact character and quality of the air at the points of take off and landing. The density of the air is a critical factor for wings to provide lift, and temperature and air pressure affects this dramatically.
Example when doing the take off calculations, a 10 deg F rise might mean you need an extra 1500 feet of runway at the projected gross weight of an airliner. And if you do not have that extra 1500 feet, you must reduce the weight, or use higher power than noise abatement rules dictate.
So no, airport weather stations are correctly sited, for their purpose which is aviation safety. What they are NOT suited for is general weather reporting, nor for climate analyses. They are not the same as siting a weather station against an air conditioning condenser, or on asphalt in the middle of a city.
Unfortunately aviation weather stations at airports take meticulous readings, every 30 or 60 minutes, 24 hours a day, 7 days a week and have for many, many decades so their complete records are tempting for climate matholes to use or misuse.
So to those who wail against bad weather station citing, and include airport stations, you are barking up the wrong tree. The airport stations are necessary and required for aviation safety. The argument should be not to include them in any weather or climate analyses.
One of my local TV weather persons was smart about this as when he’d report the airport readings, he always included the caveat that the airport was routinely 3-5 deg F higher than surrounding areas. Now he’s gone and young climate crusaders reading the weather, tout the airport temps as record highs.
The Global Warming Catastrophists (charlatans) always claim that temperatures are warming more than they really are AND they say that this will cause places to become “uninhabitable” and we will see mass migration to the Antarctic. But the opposite is clearly true. I personally know dozens of people who have retired to very hot locales like Florida, Las Vegas or Mexico and hundreds who vacation there. I know absolutely nobody who has moved to Northern Canada or Alaska to retire. Nobody. It is because humans are a tropical species and like heat.
Laughlin Nevada holds the record for highest temperature ever recorded in Nevada, 125, recorded in the 1990s. the small city of Laughlin was named after a high School dropout from Minnesota, Don Laughlin, who bought a small motel and bar there, when there was no real town. over the decades Laughlin turned the town into a tourist trap. when he died last year at age 92 he was worth a billion dollars. https://en.m.wikipedia.org/wiki/Don_Laughlin
Don was Laughlin all the way to the bank. (Sorry. Couldn’t resist.)
It looks like they added Laughlin to offset the downward bulge that occurred at the other stations about the time Laughlin was added.
I didn’t know Las Vegas had an airport back in the 1890s. Hmmmm. 😉
