No. I just said that one theory is that the sea-level will rise when the ice

there is more water in the liquid phase in the sea).
Its just that no one tested it yet wether actually melting the actual ice-caps
is going to rise or lower the sea level.
And even if you know the non-ice landscape both in the arctic and greenland,
you still have to calculate a lot of ice-volume against a lot of water-volume
to know which theory seems to be true..

Oh, so all this talk of rising sea levels and islands in the pacific
already going under water is just being wasting time? Not once we melt the arctic and the antarctic.
Then we will have lot's
of extra water all round ;-)
Scientists aren't sure of that! Because ice has a
lower density then
water, one volume-unit of ice is bigger than the same volume-unit of
water. So if the ice-caps melt and there is no ground underneath, just
ice and water, it might very well be that the sea-level goes down instead
of up!
