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.
