Here’s how it works: The ice sitting atop West Antarctica is incredibly massive. Basically, we are talking about nearly 500,000 cubic miles of ice, because the vast ice sheet is well over a mile thick in many places. This is why West Antarctica can lose the equivalent of a Mount Everest worth of ice every two years, and seem to barely even change.

And because West Antarctica is so massive, it has a dramatic gravitational pull on the objects around it. This is Newton 101. “It’s really fundamental. What you might almost call high school physics,” explains Jonathan Bamber, a professor of physical geography at the University of Bristol in the United Kingdom.

In this case, West Antarctica is so large that it pulls the global ocean toward it, which slopes upward toward the ice sheet and the Antarctic continent in general. But if West Antarctica were to lose a substantial part of its ice, then the gravitational pull would relax, and sea level would actually decrease near the ice sheet even as it spreads and increases across the global ocean.

But not evenly. Instead, areas farther from West Antarctica would get more sea level rise, and North America and the United States might get more than any other inhabited place on Earth. “The water that had been held close to West Antarctica spreads out across the ocean,” explains Penn State glaciologist Richard Alley, “and we’re far enough away that we weren’t in the ‘pile’ that was held close to West Antarctica when the ice sheet was there and its gravity attracted the water to make the pile, but

Now that is some convoluted Sh!t right there.

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.

Another thing that the alarmists choose to ignore is the amount of water saturated in the crust of the earth and how much more it can absorb.

Some scientists theorize that even if all the ice were gone, the sea level would settle back to within a few feet of where it is today. They point to the fact that the land to water ratio was really no different during the hot periods and today. Some modern seabeds were dry land and some modern dry land were sea beds but the mean sea levels were never really much higher. Basically, they say we’re pretty close to the max possible sea level now given the amount of water available.

West Antarctica is so massive, it has a dramatic gravitational pull on the objects around it.

This sentence caught my eye, so I looked it up...

Seems the premise is actually correct, but the word "dramatic" is highly inaccurate, more like a slight variation in gravity...
