The shelf, which can be up to 10,000 feet thick, is the largest of several that hold back West Antarctica's massive amounts of ice. If these were to collapse, global sea level would rise by ten feet.

Why? These ice shelfs are already in the ocean, aren't they? So their volume is already accounted for in total volume of water of the oceans. Just like a glass full of ice-cubes and water doesn't overflow when it melts.

The shelf is already floating, but if it were to melt, scientists fear continental ice masses would also slide into the sea.

Yup. 90% of the Ross ice shelf is already under water.

Their ‘theory’ is: if it melts then the land ice will flood into the ocean.

The problem with that theory is...actual science: The Antarctic land ice, because of its weight, sits in a bowl. Ice doesn’t flow uphill.

If you had researched before posting you would not have made this post!

It’s volume would also shrink by about 9% apon melting.

Excellent,PGR88. I never thought of that, but it's absolutely true. We can use that fact in arguments with the Global warming crowd.

Now why was this simple fact never exposed before?
