Well said. More people live in areas that are heavily affected by UHI than in areas that are not. As far as I’m concerned, UHI and AGW are almost two sides of the same coin: human activities making the earth warmer and less livable. By that token, it’s irrelevant to try to parse how much of these unprecedentedly hot spells are attributable to AGW vs. UHI, at least if one’s goal is to solve the problem rather than pretend it doesn’t exist.
(Sorry if this is off-topic, but I would argue that it’s not off topic when a significant portion of this sub is currently, in June 2021, experiencing conditions that are way warmer than they have ever been this time of year, and it’s hard to argue that it’s not mostly attributable to AGW or UHI or both.)
