Environmental related problems have hurt people for as long as human civilization has existed is the thing. Climate change would have to accelerate far worse than people are predicting to result in a collapse of the various nation states within north america.
The green revolution of the 60s resulted in far greater crop production per acre than climate change is expected to decrease production within the key regions for US food production less California kinda.
The US is so highly developed that it's impact here is far from civilization ending, that isn't true in other parts of the world both for development and broader geographical reasons.
