You can always plant more trees, paint all the buildings brighter colors, live underground, or move north?

PDRC can be contrasted with conventional compression-based cooling systems (e.g., air conditioners) that consume substantial amounts of energy, have a net heating effect (heating the outdoors more than cooling the indoors), require ready access to electric power and often employ coolants that deplete the ozone layer or have a strong greenhouse effect.
Yikes.

I don’t get the downvotes when you’re literally correct.

Air conditioning is literally just moving heat from one space to another even at scale the air conditioning from homes is not enough to make any meaningful difference.
Now if we want to get pedantic the stress that it puts on electrical grids that are not decarbonized and have to fire up natural gas and coal plants harder sure it is technically making everything else hotter

So if we ignore everything but the actual physical heat coming out of the radiator then yes, it’s really not that much, but unfortunately these units do not exist in a vacuum, and instead contribute to 3% of global emissions.

Dunno about your country but mine is far from 100% reneable

100% renewable, nuts. I’d actually be thrilled just to get back to 1990s levels of coal and oil-based power plants. Even that seems so far out of reach as to be a fantasy, though.
