Thermal Expansion is the key
As well as the fact that a large proportion of the ice is currently on land as water heats it expands. a significant amount of the rise in Sea level will be due to the heating of the water that is already liquid.

but it's gonna 'heat' a few degrees C
not a few dozen, i don't think water would expand THAT much as it 'heats' from global warming, is it?
i thought one of the major points of water being the 'key to life' is that it can absorb a lot of heat energy without changing very much - helps to keep biological systems at a more constant temperature.
