>Like I said, factor out the land-based ice. Now, if you really wanna scare me, Hilmar, and you know how much water is locked up in land-based ice, hit me with the amount of extra volume that would be introduced to the sea if all of it melts.
No idea.
In the Arctic, the ice is mainly floating on the sea, I think.
The Antarctic is continental, which means the ice is supported by the continent underneath. So, you have an entire continent with hundreds or thousands of meters of ice. (However, I don't think all of that will melt at once...)
Then there is Groenland, which is also covered by lots of ice. Perhaps Canada, and parts of Europe and Asia, but I don't know for sure.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
