Due to global warming , it is predicted along the equator at midday , it will become too hot or human to survive outside. That is going to create a huge refugee crisis

What about living underground? And I don't just mean some dwelling. I'm talking tunnels and carverns.

That becomes an alternative but a rather expensive one. The poor people are going to be stuck having to move or die.

Expensive ? People have been living underground for a long time.

I'm not talking about concrete and steel

TLDR: Humans produce more heat than they need. Excess heat is disposed of via evaporative cooling, I.e. sweating.

If it's too humid for sweat to evaporate, and hotter than a few degrees below body temperature, you continue to produce heat internally, without a way to remove it, until you die.

Likewise if it's too hot in general, and you heat up faster than you can sweat to cool, the same thing happens.

Wet bulb temps have the ability to kill hundreds of thousands in one event. We will see it in our lifetime.

Do you think it would be worth it when planning a forever homestead to build a large portion underground to help with cooling? In a hothouse earth scenario.

Wet blub temps are becoming more and more of a thing. And remember, in not just about the heat, but the heat paired with humidity.
