Wait... aren't AC's one of the prevalent causes of global warming, so in effect partly causing more heat related deaths?
And what about stress caused by noise pollution from AC's?
I think we need less units - not more.
Technically, but in practice....
On top of that the production of AC's is also a factor, and there is the spilling of the refrigerant liquids that only recently became much less damaging.
I’ve wondered about this many times. How much would the world cool if we turned the HVAC off for a week, a month, permanently? I mean, we watched as the natural world breathed a sigh of relief on 9/11 as all planes were grounded. We watched nature reassert itself in places humans vacated during COVID. So why not HVAC?
