That’s absolutely true about those places but where I am we have weeks of 90F days and are forecast to have many days in to 100s in within the next 30-50 years. We are all going to need better cooling

And hotter climates don’t have to worry about the winter effect this commenter mentioned

Don’t know about where you are but in the upper Midwest USA the sun is almost non existent throughout winter so it wouldn’t make much if any of a difference.
