I'm going to get a canoe and a life jacket.

Florida is a mere drop in the bucket to the whole picture of catastrophe.

Florida gets so much press. Yes, I worked my way all around the globe with this map. Bangladesh is gone. Africa is looking like a good choice!

If I have a glass of water with lots of ice cubes in it, and I let that glass of water sit and all the ice melts, when I check back, the water level has not risen, the glass is not overflowing. The melted ice (water) has simply replaced the volume of the ice cubes.

So why would it be any different if all the polar ice melts. Aside from the ecological disaster, wouldn't the melted polar ice simply replace the volume of the frozen polar ice?

It has something to do with the water being compacted into the ice and being held out of the regular water system while it is ice, and then being released when it melts. I will poke around and see if I can find something sensible.

that is not in the hypothetical glass. The ice you have in the glass melts and the level stays the same, but you add some more water and it over flows.

Why the Seas Rise
Locally, sea level can rise because the land is sinking. Globally, it rises because the total volume of seawater is increasing. Global warming drives that in two basic ways: by warming the ocean and by melting ice on land, which adds more water. Since 1900 global sea level has risen about eight inches. It’s now rising at about an eighth of an inch a year—and accelerating.

It's not in the water. The melting ice will be adding to the ocean water, making it rise.

But a lot of that will happen in the next few hundred years. We will be having to make some serious choices about abandoning Miami, Jacksonville, New Orleans, Galveston and other low lying cities in the next century.

Belgium , Holland and Denmark won't be there any more.

After NYC and the Meadowlands get swallowed up by the Atlantic Ocean.
