A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

In cities it actually does have an effect, especially in crowded ones. Millions of people in a relatively small area blasting AC "exhaust" out of their windows heat up the crammed air and in turn the buildings, streets, etc. which increases the heat island effect of cities.

Granted, it's not a huge effect, but it's measurable. First source I could find: https://www.euronews.com/green/2023/08/30/fact-check-is-air-conditioning-making-cities-hotter

Huh guess so. But still 2.4 degrees ain't a whole lot (well except on a global scale lol). Thankfully in this situation doesnt really cause additional global warming problems.

Cities are already about 5C hotter than the surrounding countryside. Adding this increase on top, means 7.5C.

4OC in the countryside is already bad, 47,5C in the city is deadly for a lot of people.

I think you underestimate, how deadly heat can be: https://en.m.wikipedia.org/wiki/Wet-bulb_temperature

Wouldn’t those 2.5C already be included in cities being 5c warmer..?

No, since most cities are not fully air conditioned.
