Yeah well this is frightening. In 25-30 years I will retire and now I need to raise the chances that I will live in a home with air conditioning in a country that -- currently -- hardly has buildings with air conditioning because it was not a necessity up until now. This will be an uphill battle. I don't want to die prematurely in a summer heat wave..
That's all well and good until your AC breaks, hits its heat transfer limit, you lose the ability to afford it run the AC, or your electricity goes out because the grid is overloaded because everyone else is also running their AC.
This is why all climate change predictions come with predictions for escalated war, famine, violence. Human 'civilization' may have just been a result of a resource glut.
