* "not technically feasible" - people talk about old buildings with oddly shaped windows
* "can't afford it" - as you see here. people talk about the units themselves and the electricity bills
* "our infrastructure can't handle it" - this has to do with things like grids overheating, failing
* "our infrastructure can't handle <the regulations>" - things like nuclear reactors in France not allowed to raise the temperature of rivers by another N degrees during a heat wave
* "it's bad for global warming" - a little late for that, probably should save lives first
literally hospitals in europe don't have AC throughout the entire building yet. global warming is really coming at them fast
