The antarctic ice has a volume of 26.37 million cubic kilometers. It does not contribute to the earth’s moment of inertia so close to the rotation axis. However, if it melts and distributes evenly at the surface, the inertia is modified. Consequently, the rotation time of the earth changes. How much shorter or longer will a day become? Keep in mind that 10% of floating ice is above the water surface; water has a density of 1 kg/dm³. The total mass of the earth is 6.4*1024 kg, its radius is 6370 km
