Yes, there are a few fringe areas that are likely to flood. But as we know that, that is not a problem. These areas are mostly uninhabited, have emergency procedures in place and are somewhat resilient (houses built on artificial mounds). Dealing with the known unknowns is relatively easy. Sometimes these areas flood, but seldom does it cause significant impact (loss of life, significant impact on economy). Taking into account all the known unknowns we have designed and built the greatest sea defense of history designed for 1:10.000 year conditions. And I am very confident this has been done properly (no expense spared). I believe New Orleans was rebuilt with 1:100 year conditions in mind, and that was after Katrina. Nothing close to 1:10.000. So are we safe then? A few years ago I would have said yes without a doubt. But now? It's the unknown unknowns I'm afraid of because they are by definition left out of the calculations to get to 1:10.000 year conditions, and we are only just beginning to discover what climate change really means. I'm afraid we "ain't seen nothing yet", and extrapolating from the past just won't cut it.
