Time has a good article about how climate change can impact our future. There are some pretty far-out stuff here, but my favorite quote from the article:
“What these surviving societies and communities will have in common is that they are able to unwind the complexity that has felled our predecessors. They rely less on far-flung global supply chains by locally growing their own food, generating energy from renewable resources, and utilizing additive manufacturing. A combination of prepping and nomadism, high-tech and simple, are the ingredients for species-level survival.”
