No, I'm just calling out the implications of your assertions.

You say,

It's crazy that you treat this as an insurmountable obstacle. Much less that there's no political cache in surmounting it.

How do you expect to surmount the obstacle? Just give them A/C units in their open-air homes? Or replace their homes with something enclosed and insulated? If it's the latter, how do you expect to do that without demolishing the existing structures?

Or do you mean to force them off their lands and put them somewhere else where you built new houses?

You seem to be doing a lot of work to try to justify your initial insinuation that global warming somehow won't affect the global south.

You scoff at wet bulb temperatures as if you have some easy obvious solution. Well, this is what your "solution" looks like in practice.
