Olives don't float, thats is why I order my Martinis without them they take up space.

But Archimedes would disagree with that too wouldn't he?

The problem with saying it would rise that high lies in the assumption that the surface area of the ocean woul remain constant...it would not. It would get larger because of spilling over onto land. Read that article that I posted. I figured that was where you got your numbers in the first place.

Just my to bits worth. I agree with Mike. The ocean isn't going to raise 200 feet straight up. It will spill over into lower lands and cover them by how much I don't know but that will lower the over all raise of the water. And there will be a lot larger part of the Earth's surface covered by water. Maybe living in the mountains has some advantages after all.

Mike and Ron,
C'mon guys - I've been saying that!

My numbers come to 89 meters if all the ice in the Antarctic melts. That is about 290 feet of water rise. But I have also stated in many of my posts that that is straight up, and that I have no way of calculating the change in surface area of the water. Yep, that 290 feet would spread out - and all the numbers that I have seen show somewhere between 170 and 200 feet when that spread is taken into consideration.

Mike, I read your article when you first posted it (it's a good one BTW), and it seemed to be saying exactly what I was saying, though my math was a bit easier.

I did re-read your article and I think I figured out where you got 4 meters from. On page 15 the article says that if 5% of the Western Ice Shelf in Antarctica melted it would add about 4 meters to the level of the oceans. That number is NOT for all of the ice in the Antarctic. Mine was.

As for my numbers - 5th grade science class for the water volume/ice cube stuff. I have a pretty good memory for trivia.
I looked up the surface area of the oceans on the internet, and I also looked up the total volume of ice in the Antarctic. The math was easy.

Steve,

Your numbers are most likely pretty close but have they taken into account all of the underground caverns and places that are very low like the Dead Sea area and such? That is almost impossible to account for as they are still finding huge underground caverns that they didn't even know existed until in some instances weeks ago. and what happens when the cold sea water gets into a vent and hit hot lava?

Ron, There was one guy who did a lot of that and came to an actual number of about 200 feet. He took all of that into consideration, as well as the open space left by the grounded ice in Antarctica.

I found this on the web that shows the US with a 66 meter rise.



Looks like Mike could end up with oceanfront property!

I've been reading this post with interest, and I'm ignorant of most of the math and science involved. I did, however, hear an interview on the radio a few weeks ago with a scientist who claimed that with all parameters taken into account (which I don't understand) the net rise in sea level would be something under 3 feet. He had a credentials list of course, but then don't a ton of would-be experts? I'll try to find that information source and post it in the next couple of days.

Steve,

The map is impressive but how could anyone take into consideration underground caverns that we don't even know about yet? Also what happens when the cold water and magma meet and it causes huge eruptions that blow out even more open holes? I am just having a problem with believing any person can figure out exactly what is or would happen in this event as there are just to many unknowns and everything they have is based on what is known.
