West Antarctica is so much more “massive” than the molten rock/metal core of the planet, that it causes the ocean to pool up around it more than any other place on earth?

If this were so, the planet would have slung itself apart eons ago. But, I dont have PhD (Piled high and DEEP) from Bouler, Co.

Its called the “center of gravity” for a reason and any given body in space can only have one.

Good Points with all your logic refuting this.

But then I realized I made the mistake first of calling this out.

The. Facts. Are. Irrelevant.

The Issue is NOT The Issue.

The Issue is the Revolution.

What can be done to advice the cause of The Socialist Revolution.

The earth's equipotential surface is not spherical, or even ellipsoidal, near sea level. The picture below depicts the displacement of "sea level" from the best fit ellipsoid in meters. If you don't "agree" with this depiction, you are free to turn in your GPS receiver.

The problem with the West Antarctic ice sheet is its instability. The mass of the ice sheet depresses the mantel below it, so that the bottom is below sea level. As it melts, the mantel will rise, causing the bulk of sheet to be above sea level and slide into the ocean, raising sea level about 10 feet over the next 200-1000 years.
