Would be nice if the article explained what causes a city to slip into a sea. What is the possibility of a modern city doing the same thing today? It just happened 1,400 years ago. Less than a minute ago in the earth’s history.

As far as the “possibility” goes, I’d say it’s just a matter of time. You’ll find that article I linked to pretty fascinating, I think. Sobering, too. I sure did.
By rights much of New Orleans should be underwater, but our engineering capabilities and national sense of nostalgia keep it out of the drink.
