When you refuse to build climate-appropriate homes with things like isolation and instead guzzle giant amounts of fossil-powered energy to compensate for it? Yes. That's not adapting, that's brute-forcing.

AC is sorely lacking in the EU, e.g. right now I have one in my office but not in my bedroom and nights are horrible, but I do read a lot about people overdoing it quite a bit with AC, aiming at 18-20°C during 30s outside which is a huge energy expenditure when a healthy human should be perfectly fine at higher temperatures

Spain's continental climate has both subzero Winters and scorching Summers.
