People don't seem to understand what I'm saying. If the OP at least gives numbers you can compare them to easily looked up estimates and find out if they're reasonable or if you can ignore him in a couple minutes. Without that I'd have to search projected sea level rise, then read all about the elevation, vulnerability to storm surge, levees, flood risks, etc for New Orleans. It would take hours to know if the OP has a valid point or not. You might have to do that anyway, but at least if his numbers are bad you can shortcut the process and ignore him.
