No. I just said that one theory is that the sea-level will rise when the ice
melts. But another theory is that the sea-level will actually drop (while
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..
