My guess is that ****fting of mass inside the core is more likely to
alter the rotational velocity of the earth than melting water. Even
the entire crust of the earth is infinitesimally thin, in relation to
the size of the earth, and the spinning, molten nickel-iron core is
vastly more massive, and also in motion. At least, that's the current
theory as to how the earth's magnetic field is generated. :-)
