Hansen still can’t find the UHI, 25 years later.
U.S. Data Since 1895 Fail To Show Warming Trend

What About Urbanization? One aspect of the study that Dr. Hanson said was interesting was the finding that the urbanization of the United States has apparently not had a statistically significant effect on average temperature readings. A number of scientists have theorized that the replacement of forests and pastures by asphalt streets and concrete buildings, which retain heat, is an important cause of rising temperatures.

This would be same UHI effect which scientists measured in 1907.

Typical.. GISS was “adjusting” for the UHI they can’t find or know nothing about.
UHI was discovered in 1789:

“After examining climate data extending back nearly 100 years, a team of Government scientists has concluded that there has been no significant change in average temperatures or rainfall in the United States over that entire period.”
Hmmmm, government with a capital ‘G’.
It must be the same UHI that causes the wether girls on UK TV to say “but it’ll be much colder in rural areas” whenever a frost is forecast.
Sticking your thermometer up a 747s “asshole” doesn’t help either !
