> In the US, at least, air conditioning is somewhat common from what I know. Afaik that depends on the specific region in the US. Some states have hot regions where AC is common, but plenty of others don't because heat didn't used to be as common as it's now, thus the sudden need for cooling to such a degree that even public cooling shelters are a thing [0] Another factor, even for places with AC, is that their infrastructure and AC is built to certain heat expectations, if the weather goes outside these expected then the infrastructure can't cope. A version of that was the Texas electricity grid failing during the sudden high demand of a "real" winter.
