"But this story about a six or seven foot general rise in sea levels is nothing but malarky meant to scare the gullible." Actually such could easily happen and in a matter of minutes but it would have nothing to do with Global Warming and everything to do with "Plate Tectonics"

I'm not sure what you are getting at here, but there is NOTHING that can cause a net global rise in sea level except a massive addition of water.

I suspect you are talking about a localized land subsidence.

Well being these folks are using shorelines as their measuring points yes after a great cataclysmic shift those points could be moved several feet. Such has happened in the past according to geologists. And being such has happened in the past this tells us without a doubt it can happen in the future.
