I mean realistically it’s all going to hell sooner or later. You’ll start with millions of climate refugees, closed borders, violence. Then climate wars (a wall with machine guns isn’t going to stop people who have no other way to survive). And if a country with nukes (like India) finds itself uninhabitable then things are really going south. Next up you have a possible nuclear war and the end of humanity as we know it.
Sure, a small amount of humans might survive, but civilization will go down in chaos. Even areas that are inhabitable and have plenty of water will break down, because the local infrastructure can’t support hundreds of thousands of refugees forcing their way in.
You’ll start with millions of climate refugees
Millions? If only.
I’ve seen estimates which say at least a billion by 2050:

Oh, I was more thinking per area. Not all refugees will go to the same place.
It will start with millions and that might already be enough to cause collapse. When it’s over a billion it’s already over.
The whole Syria thing already caused us lots of issues in Europe. Arguably the civil war was caused in part by climate change exacerbating a drought. The surge in refugees helped the far right and populists across Europe and was a factor in brexit.
I can only imagine what’ll happen if it gets worse. Children of Men is likely to be eerily prophetic.
I’ve seen estimates that say a billion dead by 2100 is the most optimistic possible outcome. Even the notoriously cautious IPCC is making the most unimaginably dire predictions:
In its report focusing on the impacts of global warming on people and the planet, the Intergovernmental Panel on Climate Change says that every inhabited continent is already experiencing multiple climate impacts, from droughts and flooding to biodiversity loss and falling food production. Between 3.3 to 3.6 billion people live in areas “highly vulnerable to climate change,” the authors warn, with “additional severe risks” should the Earth warm beyond 1.5 degrees Celsius (2.7 degrees Fahrenheit).
