this is (strictly) true, but only would be relevant if all melting ice
were free-floating ice, but as you are probably aware there is much
ice which is not free-floating, and that is what creates the potential
for rapidly rising sea levels.
and a host of other sites via google: "glacier melting rising ocean
remember too that a significant component of predicted sea-rise is in
thermal expansion of sea-water due to rising temps. also, loss of ice
sheets means earth absorbs more sunlight, etc., so accelerated
warming. thus in a deeper sense, sea ice melting COULD affect level of
oceans via feedback mechanism.
