For what it's worth they can live under ground [1][2], even build cities but they would have had to start that project some time ago. Before someone says it, yeah not everywhere and its not for everyone but in enough places and for enough people that we can adapt to heat and at least survive as a civilization.
I stayed in a mongoloid home in Tunisia last year. It was lovely. It was a large, central, below-grade courtyard with dugout, underground rooms branching off it. The rooms were cool all day. By being below grade, the courtyard was in shade most of the day and didn't get too hot. Through clever tunneling, the rising heat generated a draft.
I also learned that mongoloid, at least in Tunisia, is not considered a derogatory term.
There are cautionary tails about everything humans do. Good leadership and the desire to survive can keep some of us around. If we have to stay down there for thousands of generations, well, it won't affect me or anyone I know. We can jump off the evolutionary bridge when we get to it. Ideally our automatons would be geoengineering the planet to make the surface hospitable once again prior to our becoming Trogs.
I would posit that good leadership and desire to survive could prevent humanity from retreating to the earth like naked mole rats.
It very well could. I like having contingency plans and not letting my survival and the survival of our civilization solely depend on the promises of congress critters. I also want to learn earth bending from the giant badgermoles so I am biased.
I hadn't considered the badgermole angle..fair enough. Have this webcomic that I spent more trying to find than I should because I get flashbacks whenever I hear people throw out the "we'll live underground" angle
you cannot build an underground shelter under extreme heat.
Yup. That's why I said,
"but they would have had to start that project some time ago"
When the day comes do you think there will be room for everyone?
Depends when the project starts, how much money goes into it based on the nations priority. There are subway systems in some countries designed for this purpose that can hold entire cities. Not entire nations but enough that a nation or civilization could be restarted. It would be a very rough start.
If countries started putting a small percentage of their GDP into building underground cities a few decades ago they could probably save most people. They would have to store up massive amounts of freeze dried food and have water treatment facilities that can hold lakes of drinkable water.
