The laws of physics teach us that a body floating in a liquid displaces a volume of liquid equal to the weight of the floating body. I understand that the north pole (unlike the south pole) has no land mass, but comprises floating ice. If so, how is it that melting of all this north polar ice would lead to a rise in sea level? The volume of sea now being displaced by the floating ice would simply be filled by an equal volume of water that would be created by the melted ice. Hence, no sea level rise when the ice melts.
