Laws of physics and thermodynamics would dictate that the Earth would shrink a bit as it cools.. hence sea water levels should advance, albeit minimally, as the mass of the Earth loses a bit of girth. just a theory. :-)
Off the wall, but posssible, Water has weight, the shear weight of the water maybe sinking things....Just sayin....
Amusing, but water would also contract as it cools along with the planet. The only point where the water would expand as it got colder is below 4°C (about 39°F) . . .

Credit Fred with pointing that out on a thread some time ago.
