There are entirely different reasons. War.
Make a people's land unliveable, and make it so they cannot grow crops any more, and those people will come for your land. Imagine if 1B people decide to move to where another 1B people live, but are still struggling with climate change? Barely making it by?
So I agree with your point, 100%. You are right in the direct mortality. But also felt a tangential point of "secondary effects" was important, and this seems a good place to put it.
Global warming isn't going to actually kill many people. Instead humans fighting over resources will, I think.
An example. Canada has a population of 40 to 50million. Now imagine if for whatever reasons, much of the Souther US becomes unliveable, and at the same time, Northern Canada becomes viable as a place to live.
Now you have 100M people wanting to cross a border in a period of a few years. How can a country of 50M absorb 100M in that period of time? Chaos.
That won't end well.
