I am not sure how not directly linked to global warming. I am currently on the phone but I remember a study that mentioned that Pakistan, India, and Bangladesh would see a deadly heat (wet bulb temperatures) from basically 0 as it is right now to 30 days/year by 2050 or 2060. I can't remember right now.
If that is not linkable to global warming I am not sure what is. And that is a huge event. In Europe we are struggling with accomodating perhaps 10M people. What happens when 1.5B come knocking because if they stay they die?

We sink the boats.
There are also statistics showing that mortality because of cold is much higher than mortality because of heat.
About 9 times higher.

More taxes go to ammunition for autonomous border guard systems.
Patricia Anthony published a novel about this in '93. Cold Allies. It's good military sci fi. Doesn't pretend to offer answers.

Like let them build few of those sci-fi domes and let them keep buying disposable bottled oxygen? I don't get the pessimism. India makes its own rockets. Pakistan has nukes. Why are they supposed to be incapable of holding the nation together on Mars-like Earth?
Tokyo is already hitting 40C/100F at >90% RH during summers. It's already mildly unsurvivable. Nobody cares. Maybe in 10-20 years we'd be wearing spacesuits, but do anyone seriously think the equatorial regions will be uninhabitable and land prices on northern Europe is going to skyrocket???
Chapter 1 of "The Ministry of the Future" describes a fictional wet bulb event. It's grisly and horrific and I highly recommend you read this chapter, it changed my view on climate change.
