The midway point in the sea level tool you linked is actually 1.41m by 2100. That's 4.6 feet of sea level rise by the end of the century and this is based on our current models where we are continuously discovering more and more positive feedback mechanisms that is accelerating sea level rise. (https://www.science.org/news/2020/11/seas-are-rising-faster-...) Now those levee walls that were originally 13 feet high are now less than 9 feet from the water and no longer really capable of doing the job they were designed for. So we better build bigger walls to keep all the water out, so let's go back and spend billions and billions more to have bigger walls, which by the way encourages more and more people to move into flood prone areas. Then you really set things up for a black swan event where something unexpected causes a levee failure (b/c that's never happened before) and then a bunch of people die.

So maybe you and your kids MIGHT be okay, but your grandkids and your great-grandkids? probably not.
