It is intolerable now! Air conditioning and modern transportation are the only thing that make the climate livable now.
As to your question. Look at the hoards going to Europe. That is where they will all move to once it is too hot to stay put.
BTW: It is not warming anyway and if it is, there is nothing we can do about it.
Intolerable and intolerant.
Even if it were 75°F and sunny every day, 65°F every night with warm showers overnight sometimes, it still would be intolerable! Not the weather, but the people and their false religion!
Sounds like Phoenix most of the summer.
