Just wondering if there were any plans at all for this state since it appears with sea level rise most of the current coastal areas will be gone by 2100.. That's really not very long away. Conservative seal level rise estates put much of Miami, Tampa, St Pete under a couple feet of water.

Where is all this water going to come from to put Florida cities underwater?

Conservative estimates within the range of IPCC predictions are around 1-2 foot by 2050 and 3-4 ft by 2100. Enough to cause issues, but not the end of the world. IMO, better to prepare for the 1-2 ft by 2050, the predictions of 2100 and beyond are just so uncertain and we'll probably have some new technology by then.

South Florida will feel the effects first--we already are, actually. Tidal flooding makes some roads on the beaches and along the bayfront and intracoastal impassable during high "spring" tides. It used to be only during extreme tides with the winds pushing the water on shore, but now it is noticeable almost every spring tide (around the time of the full moon). Miami Beach is currently installing a pump system to try to pump the water back into the bay during high tides, we'll have to wait to see how effective it will be...

jambo: at least for the 2050 predictions, most of the additional water volume is due to thermal expansion, based on the warming trend we've already observed in the past century (which has arguably been less in the past few years, but the ocean responds on longer time scales..we've pretty much already "committed" to this sea level rise and it would take decades of cooling (or massive re-glaciation) to reverse it). Arctic ice melt doesn't contribute as much because most of it is already in the ocean as ice bergs. But melting the ice caps and glaciers which are over land can raise the sea level, much the same way as the end of the last ice age, when the land bridge from Asia to North America disappeared.

From the imagination of the MCGW groupies.

Ice caps melting...

Yes, conservative estimations. It seems like there isn't much of any plan down here..

I dont know but seems I should worry or at least consider that "my world will" end for me at any time? heart attack? accident? crap falling from the sky? this I am sure of...

As hurricane kid pointed out all the arctic ice and a lot of the antartic ice is already floating so its already displaced its own volume of seawater, kinda like an ice cube in your drink doesnt raise the water level in the glass as it melts.
I'm not so sure that the melting of the rest of the Earths glaciers plus the ice on the landmass of the antarctic contain enough liquid to raise all the the oceans by 2 ft or more.

These horror predictions made up are always always on the "conservative" side. Just more doom and gloom from the money making scientists.

Sea levels have risen by like 3 inches every century for the past 5 ones or so. Yeah, it's just soooo believable that sea levels are going to suddenly rise by up to 48 inches by 2100. That would mean that sea levels are rising by .4-.5 inches a year. Sea levels here in my town don't look any higher or lower than they did ten or fifteen years ago.
