How is it true? Even if emissions went to 0 tomorrow we'd still have heatwaves in Europe. It'll take at least a century to do carbon sequestration back to pre industrial levels even on a very optimistic timeline. Until that's made a good amount of progress, it's common sense to have AC in the places where the most vulnerable gather. Their homes, public transport, train stations, hospices, hospitals.

It isn't necessarily true. Here (bottom of the sea) it's only hot when the there isn't any clouds, so solar energy that produces the heat is also producing the electricity to run the AC.

It's also a misdirection of guilt. It's not the accumulated CO2 from the decades of burning all kinds of shit that is driving the weather, it's your personal AC unit.

Indeed. It is true. However, it's not exactly helping if the other side of the pond burns gas turbines to power their AI dreams and tells us to "just get AC bro".

AC does make the problem worse, the issue is just that climate change is mostly out of Europe's control.
