The rise in sea level is something of a misnomer, because the real damage comes in storm surges. Even a 1cm rise increases the amount of water that can pushed inland by *checks notes* a whole helluva lot. So while manhattan isn't going to be put underwater even after a whole foot of sea level rise (predicted by 2100), the storms it has to survive will be much worse.

People won't move just from a little water in the roads (just look at Miami), I think even in the year 2099 you'll have a hard time getting new yorkers to move to ohio, but once a storm comes through and destroys their housing they will have to find somewhere else to live.
