I have been showing how summer temperatures have been declining at well sited rural stations. Now I am going to show the exact opposite. The weather station at Fort Collins, Colorado showed a huge jump in temperatures when they started building the CSU Transit Center around the year 2000.
In 1937, the station was located in the middle of a farm.
By 1950, the area was starting to get built up.
By 1969, the city had surrounded the weather station.
Now it is in the middle of a parking lot in the downtown of a large urban area, which has more than tripled in size over the past 60 years.
It’s no possible to add this much concrete and asphalt and not make it hotter and warmer at night….this is just roads

One just need to walk farmland barfooted on a very hot sunny day
and then a concrete desert.
You can walk the farmland for hours
but only seconds the concrete even when it is 5 degrees colder there.
It will be interesting to read what Scott’s BS on this will be…
He could not possibly accept the facts of UHI ..
He’s not that interesting. He is arguing the same stuff I used to before I became disillusioned by reality. Perhaps he could continue with the intellectually dishonest straw man that Tony is representing a global trend. ;-)
Al: Scott’s whine is that Heller is cherry picking “only one station”, so he can’t move off that thread.
Drive-by troll perhaps?
So shouldn’t we be banning any and all forms of urbanization – its clearly bad for the environment. I’m only half joking, compared to Co2, urbanization is clearly a far greater influence of median temps in people’s lives (since urbanization has increased dramatically over the last 100-years and most people live in urban areas).
For over three decades, CO2 fertilization is greening the planet – the opposite of the failed “desertification” prediction, just one more on the trash heep of failed AGW projections.
But, but, but, we adjust for UHI. We adjust for it totally accurately. Of course. We’re sure we do. Just look at the Official record. (do I need a /sarc?)
It’s simple really.
Urban heat forms islands. Islands are subject to sea level rise. So, raise the C (Celsius) level to match. Adjustment complete!
And, if the island’s population were to increase, oh what environmental tragedy could follow…

Well…we must adjust the temps upwards to compensate for the upward UHI
Hey???? are you a climate scientist, lance ?
(I apologise for any implied insult !!)
We just had a warm early May Bank Holiday, the BBC etc. just went on and on about it being record breaking hot. This Bank holiday falls on random dates in May and has only existed 40 odd years, so yes, given those restricted/random criteria – it was a record. But the temperature did not even exceed the April daily record, let alone the May one.
More relevant to the article above, every single one of the hottest 20 odd locations when I checked at peak heat, was either an airport or an RAF base (aside from 1 location in Kent that is known to be dodgy and frequently too hot).
The final ‘record’ was taken by RAFNortholt in West London!
Like such a location could possibly be a reliable comparison for recent records, let alone temperatures recorded 100 years ago.
Does anyone know how much GISS adjusts temps for UHI?
…or do they just increase their uncertainty
I doubt GISS even knows what their UHI adjustment is, but that comes as no surprise, as they are UHI deniers.
Where I live, near Memphis, it’s a full 2 to 3 degrees cooler in the daytime and as much as 8 degrees cooler on clear calm nights here in the suburbs. Only a complete moron would think the temperature at Memphis International would even be close to accurate. In 1960, Memphis International was surrounded by a cotton feild. Today it’s surrounded almost entirely by concrete and is either first or second busiest airport in the world depending on time of year, when you consider freight planes.
Latest research shows min temps in the US have cycled, The max temps match Tony’s graphs quite well. with a huge peaks around 1940-1958
I refer all to the ‘Berkley Earth’ results which examined whether urban heat was unduly influencing the record by looking at thousands of stations… and concluded it was not.
Paid apostles, griff. Even YOU should know that by now.
And their methodology was basically anti-science JUNK.
A very good example. We know for sure, that rural stations has been shut down in large numbers the later years.
Some years ago they had an all time high, at Heatrow, London, supposedly, right behind a jet engine. MSM was all over it.
Also note the increase in global temps just after the fall of the USSR … When the USSR collapsed a large number of monitor stations in the cooler regions they maintained were shut down removing a large data set of cooler sites causing a increase in global warming..
