not the most well read dude, but my understanding is that as there is more energy in the atmosphere, there will be more unstable weather patterns - and will lead to crop failures.

this will most likely hit the global south and nations that are less developed (exploited nations such as the global south) harder than the developed nations. people migrating because they can't live in the deadly heat, or not having enough food, or something about florida going underwater (iirc they won't insure houses in florida anymore because of global warming and rising sea temperatures.)

edit i don't think people will want to lay down and die from the inhospitable environment, they will probably move - i don't think looking at the death toll and saying "see there are less deaths from the climate therefore climate change is not significant" is a good form of analysis, it seems like a bit of a kneejerk reaction, that needs more inspection - like quality of life, crop failures, if you can go outside without heatstroke, these things are gradually ramped up on a scale
