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.
Then heat pumps in winter will lower winter temperatures.
Unfortunately it does not work that way :(
Whoosh
Ah, I was afraid that might happen. Oh well.
I remember a statistic claiming that at the peak of the Iraq war, the annually power consumption of US military ACs alone exceeded that of the African continent.
turns out running AC to cool tents is super inefficient. Who could have known?
