Your McDonalds example is a really good one. McDonalds, as of 2012, serves about 68 million people per day. In climate migrants/day we get an aggregate of 13 million over 82 years. That works out to 434 per day. And that's on the extreme negative end of outcomes for climate change.

To give some context to the numbers here [1] are states' net migration rates. So for instance Florida currently has a huge net migration rate of 16/1k. For a population of 21.3 million that means they're seeing 340,800 new residents per year. That's 933 per day. So the entire climate migration, in the worst case scenario, will involve the entirety of the US taking on half as many residents per year, as Florida alone already does. Of course it won't be entirely evenly spread out, but it also won't be jumping from e.g. 20 people/day to 20,000 people/day. It will mostly pass without major notice and, as the article mentions, is indeed already happening.

This makes for nice shocking headlines, but this entire article is extremely hyperbolic. At the same time I don't think anybody really cares. It seems like people want to be terrified, even when the numbers in no way justify the claims. We are increasingly indeed living in a post-facts world.
