Inetersting maps that show how Wilmington, NC would look if sea level raised up from approx. 20 inches on up to over 6 feet: Wilmington Underwater

Good post, not as severe than I would expected. It will happen by the way, simply a matter of when.

I'm no expert on this issue but some common sense tells me that we will NEVER see a 6.6 foot rise in water levels unless something catastrophic happens but certainly not from man made (or natural) climate change. I know the globe is made up of approximately.......

139,000,000 square miles of water (about 70%)
57,000,000 square miles of land (about 30%)

and about 6,000,000 square miles of the land is covered in ice which is about 10% of the total land area and about 3% of the earth's total surface area. Now if my math is correct, you'd have to melt 153 feet of ice from all 6,000,000 square miles to increase the water level 6.6 feet. Am I right on that?

139,000,0000 water area (divided by) 6,000,000 ice area = 23.16

23.16 x 6.6 feet = 152.85 feet of ice

Unless my math or methodology are incorrect I'm gonna assume we're safe. I can't see any situation melting off 153 feet of ice from every square inch of ice area on the planet. I'm not even sure there's a 153 feet of ice available for melting. What do you think?

Whenever anyone asks me, "How this property ever flooded before?". My answer is always "yes" when you use forever as your time frame.
It has flooded. It will flood again. That is a certainty. The real question is what is the flood potential now and what is the rate of change in the variables that affect flood potential.
Most folks don't really understand why an area floods. Invariably-Proximity to water is believed the only cause.

OOPS!
"How this property ever flooded before?". Should have read, "Has this property ever flooded before"

Of course, when your house floods, then it will (by definition) be in close proximity to water.

However if you want to determine whether a piece of real property is prone to flooding - proximity to a body of water is only a small piece of the puzzle. The main culprit is proximity to drainageways - which of course carry water. Sometimes these drainageways run right through a property, or even right through a house. Another factor is soil types - and their ability to absorb water. Another factor is stormwater infrastructure, and its capacity and functionality.

As far as the map goes - I considered creating one of these. My concern was that I did not fully undertand the scientific value of modelling sea level change. I concluded that it would be too political in nature.

In regards to global warming?? Nahhhhh!!!!!!!! Can't be! You mean some one or some group is trying to maneuver people, places and/or things to their own advantage?!?!
Say it isn't so!!
