There’s really not any real doubt about it.
Cities, with their millions of tonnes of steel, asphalt and concrete act as ideal heat-absorbing sinks which take a long time to cool down at night. Just drive on a hot summer night through the country side and into a city makes that very clear.
Yet global warming activist scientists don’t like talking about that because it distracts from their flakey CO2 warming claims.
Now a new study looking at the urban heat island (UHI) effect on London titled “How much has urbanisation affected United Kingdom temperatures?” confirms real impact of the urban heat island effect. The study was published in the Atmospheric Science Letters.
Hat-tip: Reader Mary Brown
Here’s the abstract of the study (emphasis added):
That alone accounts for a very large part of the 20th century warming. But the alarmists certainly don’t want to hear it.
Yes Pierre, all those towns and cities, all that concrete and black-topped roads and parking lots.
But also in the countryside it’s increasingly being turned into industrial buildings. Away with the fields of fruit and vegetables and in with industrial sized glasshouses (https://www.telegraph.co.uk/news/earth/agriculture/farming/10321390/Thanet-Earth-the-farm-of-the-future.html), and hundred of acres of poly-tunnels (https://www.independent.co.uk/news/uk/this-britain/strawberry-fields-forever-the-polytunnel-debate-5329481.html ). The majority of chickens, pigs, and cattle that are for the human consumption, are kept in industrial sized, climate/environmentally controlled concrete buildings.
Even some of the sites that make-up the stations from which the CET is derived have been criticized — https://wattsupwiththat.com/2017/01/29/what-do-three-cet-reference-weather-stations-used-by-the-met-office-have-in-common/ .
The MO took a decade to do something about, and so they tweaked the temperature records. And guess which way it was done, humm, how did they know the past was cooler?
Add to that those vast area of solar panels, along with all those trees ripped out and replaced by wind farms, is it any wonder the thermometers say it’s getting warmer.
No so much global warming as local UHI effects across the whole of the UK.
The rest of the warming can be related to more sun hours due to less clouds.
16% more since 1980? (must be checked)
We have the same in Nordic countries with 17% more in Sweden.
Mostly during spring and summer.
UK-wide sunshine increased by about 16% since 1978, which was a low point.
Apart from any increase in sunshine or decrease in cloudiness, the air in major western cities is much cleaner today than almost any time in the past century. There is much less smoke and visible smog, which must affect the amount of solar radiation that reaches the surface.
JOLLY GOOD SLOW!
LOL – “Royal Meteorological Society confirms….”
….what everyone else has known about for nearly a century.

About time, guys!
Again I say thank-you Yonason for the link.
Very interesting reading, as the author says is was a shame that wind speed could not be measured back then.
Thanks.
Interesting that the Stevenson screen wasn’t introduced until decades later.

One thing the attracted me to science was the integrity of early scientists. Even the “average” guy was usually exceptional, by today’s standards. I would not have bothered at all if what I had as role models were today’s crop of charlatans.
