One big reason the sea level dropped for so long: Only 6 % of the rainfall in Australia runs directly back to the sea, and the rest runs inland to lowlands (image depicts a normally dry area in eastern Australia flooded by rains in late November 2011) where it either soaks into the ground or evaporates back into the atmosphere — a process that returns moisture to the sea far more slowly than the rivers draining other continents do.

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.

The trend in greater sea level variability means that many Pacific Island communities should expect not only more frequent and prolonged drops in sea level, but also more frequent high sea level events.
