Huh, I still don't see how ocean levels would increase if the polar ice melted. It doesn't jive with chemistry at all. If you have water with ice cubes in your glass and then let them melt, the water level in your glass will be slightly lower.

And on that note, the oceans are not at a constant level around the globe. They buldge by something like 20m (or feet, can't remember) at the equator due to the spin of the earth.

what your saying is correct, however, lets add a spoon, if the cube melts on the spoon and leaks into the glass it will have more water then at the start

and the spoon is solid land

Your analogy of ice melting in a glass is inaccurate for this. My theory suggests that Ice in the poles melts and moves into the oceans. For it to fit your annalogy, the ice you speak of would have to be outside the glass of water and when it melts, it flows into the glass, raising the level of water. Antarctica isn't floating in the ocean.

Nice! I was going through posts and replying one-by-one. I didn't realise that you already cleared things up.

Thanks.
