Actually, using gross approximations and your numbers, 23 feet isn’t far off. I see how the greenies made the computation.

Interesting. If you get a chance, would you mind sharing your calculations? I'd like to see how that works (and see what I should have done ;-) Thanks!

I tossed the spreadsheet. But it was something like:

Depth of G. Ice Sheet (estimated 2.5 km average)
x Area of G. Ice Sheet (km)

---

Volume of G. Icesheet (km3) divided by
Area of Water on Earth (km2)

---

Change in depth (km)
x 1000 (m/km)

---

11 meters or about 30 feet

No adjustment made for difference in density of ice vs water. That would bring the number down some.
