I guess I assumed you didn't read it based on this. "lol now you’re pasting a book at me… like I said localized flooding in contained geographic regions happens."
The only reason I can see for this, is either you didn't read it or your idea of "localized flooding" includes the majority of land on earth being inundated with water from every ocean. If you're thinking "Waterworld" where there is no land anymore, that's not what we're talking about.
