I should clear up what I'm saying here. The thermal expansion of
water is a constant. However, the ocean won't heat up uniformly. The
rate will depend on factors such as ocean depth and the presence of
currents. That means that even with a 1 degree centigrade /global
average/ increase, some places will heat up by 3 or 4 degrees, and
thus increase in elevation by 50 cm.
