I ran the “sea rise” calculations myself, to see what complex model they used.

If you take the area of the ice cap times its mean thickness, you get an approximation of ice volume. Then you simply see what the volume of water would be, if it melted (a simple density change), and you get a number crudely approximating the water volume. Then add that volume evenly to the volume of existing ocean, and you get the “sea rise” number everyone tosses around. This is not a complex model, it’s back-of-the-envelope hand calculator stuff, with a few numbers from Wiki thrown in.

I did not consider density changes as a function of ice depth, I also assumed the ice is isotropic with no internal structure, and did not account for salinity or gravity. But I got the same “sea rise” number, so I probably got the “model” correct.

When scientists suddenly discover that the problem is more complex than the scare numbers the greens toss around, I am not surprised!

If the ice cap melts, how much of it will end up in the oceans an how much will evaporate into the atmosphere as water vapor? If the earth and atmosphere is warmer, the air can hold more water vapor, no?
