New York City has good bones. In the swivel of every moment and in the mad blur of millions of lives lived uptown and downtown, our grid sits unchanged. But global warming could change all of that.

With sea-levels rising around Manhattan, flooding in New York City will no longer feel like a once-in-a-lifetime memory.
