>That's a lot of people to move and things to rebuild. Op did say "the current round of civilization". If that's the bar for civilization ending, then civilization ended when people came to the US, ended again when they expanded out to the West, etc. Just because people on the US coasts move means little to the 60 percent of citizens that don't live near the ocean. And again, it's not going to happen overnight. A wall of water isn't coming in that will force everyone to put their things in a car and go. It will be slow build-up that slowly forces people out as they decide it's to expensive to mitigate.
