Oh, absolutely. That would be an instant massive humanitarian disaster. I was more trying to respond to this though:

just pointing out that since the first human put an animal skin over their shoulders we’ve been developing technology to live in places that we’d otherwise not be able to exist in.

I think there is a big difference between the passive warming / cooling of clothing vs the huge energy requirement, spent resources and emissions required to basically run your entire home / office / factory / hotel as a giant fridge.

Essentially going through some of the ancient technologies used for cooling buildings.
