There is also erosion. Where do you suppose all that dirt that washes away in our streams and rivers goes? The Mississippi Delta gives us a big clue. The dirt goes to the oceans and settles on the bottom. All that displaced water from the bottom of the oceans being raised has to go somewhere. I tend to think the ocean levels rise as the land gets lower from erosion.
Then too, as ice melts, it shrinks in volume and I've never seen that acknowledged by those climate fear mongers, but as it will get colder like in during the repetitious ice ages, the polar caps will increase and the ocean levels will drop which makes all of the blather moot.
Erosion is a one way street. It won't reverse like ice ages can effect ocean levels and polar ice cap volumes. These all-in-the-know climate fear mongers need to figure out a way to dredge the ocean floors and put that dirt back on the land from whence it came. I know one thing though: It'll never get done with electric dredging machines!

And, speaking of the erosion, where did all that "material" that was moved by the Colorado River from the Grand Canyon go to? Is that why there is a Baja Peninsula?
Having seen the Grand Canyon and the tributary canyons within Canyonlands National Park with its Green River, all that "soil" had to go somewhere.
