As others have said, it's already happening, and it'll only get worse. But since it's not western countries it's not highlighted much.

But when the AMOC stops and western Europe's winters get longer there will be huge changes too. If I recall correctly, the AMOC stopping is a trigger for an ice age, that is, ice sheets / the north pole going down way south. This would make anything above France uninhabitable, if not wiped off the map entirely.

But it'd be a steady process of increasingly cold winters, so likely in our lifetime it'd mainly mean we change how we build houses and buildings. But long term, people would move.

Some say it was a factor in Syria as well:

I am really puzzled that this topic is not present in the public discourse.

They have been talking about climate change for years (ozone layer - get rid of your old fridge). And the media really does highlight weather events in other countries. I think the idea is one corporations can get behind - change, like war, is good for business.

Are you writing from e.g. 2008? In 2010 Russian forest fires caused grain shortages and the price to go up, creating the Arab Spring and including the start of the Syrian civil war. That caused a wave of refugees that peaked in 2015. That caused the rise of right wing racist populism in Europe...
