An ice cube floating in a glass of water does not raise the level of water in the glass by the volume of the ice cube. Rather, it adds volume according to the volume of the ice above the water, less the contraction factor when the water changes phase from solid to liquid, less ablation of the ice, less evaporation of the ice as it melts.

If the polar ice evaporates it must latter appear as rain. The Earth is (more or less) a closed system.

If (a BIG BIG if) the coastal ice in polar regions disappeared, the much of the ice trapped on land masses would find it's way into the oceans, and the land under it, no longer weighed down by the ice above them, would rise. The magma that bouyed them up would come from that maintaining the present level of the continents, which would sink proportionately. The ice above polar regions would increase the volume of the oceans and the lack of ice above the polar regions would cause the continents to sink.

Don't sell your summer cottage on the Outter Banks, just yet.
