Hey Wait A Minute!
If I put ice cubes in my water, they float. They float because they displace water equal to their mass, and water being more dense than ice, up they go. When my ice melts it exactly replaces the water formerly displaced and the water level in my glass doesn't change one bit.
So, if we warm the globe enough to melt off ALL the arctic sea ice, how does that raise the level of the ocean one bit? Land based de-glaciation I get, but that's a really small percentage of arctic ice. What am I missing here?
