The urban heat island effect adds far more non-climatic heat to temperature station records than can be reliably controlled for.
An analysis of 10 cities from across the globe (Kara and Yavuz, 2025) reveals airports and industry centers are, on average, 2.5°C to 2.8°C warmer than neighboring green spaces.
“Airports exhibited a mean daytime land surface temperature (LST) that was 2.5 °C higher than surrounding areas, while industrial zones demonstrated an even greater temperature disparity, with an average increase of 2.81 °C.”
The urban heat island effect can leave airports and industrial centers as much as 12°C warmer than nearby vegetated, forested areas.
“Mexico City’s green spaces are up to 12.13 °C cooler than its urban core.”
Warming trends in recent decades are generally confined to urban areas, whereas non-urban areas have been cooling. For example, from 2001-2021 urban areas warmed +0.04°C/yr, but vegetated, bareland, and water body areas cooled -0.07°C, -0.03°C, -0.04°C/yr, respectively, in the city of Chongqing.
“In contrast, cold spots characterized by dense vegetation showed a notable cooling effect, with LST differences reaching −3.7 °C. Similarly, proximity to water bodies contributed to temperature mitigation, as areas near significant water sources recorded lower daytime LST differences, averaging −4.09 °C.”

The ‘climate change’ crowd can’t get away from highlighting asphalt as a place which supports their preoccupation for manipulation and control based on false premises.

I see this phenomenon all the time. I live in an urban area with a population of over one million. As an amateur astronomer, I usually drive about 20 km west of the urban area to a rural site with much darker skies. In the evening, the temperature is often at least 5 degrees cooler or more in the rural area. As I return to the city I can see the temperature rising again as soon as I enter the built-up area.
Unfortunately the trend in many countries has been to close long-operating rural weather stations in favour of “extrapolating” from a smaller number of stations concentrated in the population centres.
Of course cities are hotter , they are not using sunlight , the green areas are using the suns energy for photosynthesis .

The main effect is due to changes of evaporation which in turn is related to vegetation. So even cutting down woodland and growing wheat has an effect. That is why it is pointless attempting to take precise temperatures for long term comparison unless it is in an area where the type of vegetation for miles around is also controlled long term.
All that almost all long term stations are really doing, is reporting local change of land use and NOT anything to do with global temperature
