When the convective processes of the atmosphere remove enough water vapor from the oceans to drop sea levels and build polar ice caps, as has happened many times before, the top 35 meters of the oceans where climate models assume the only thermal mixing occurs, must heat up cold ocean water that comes from depths below the original 35 meter depth, removing vast more amounts of heat from the earth's surface and atmosphere.
