David Payne: Climate calculations

Regarding the Dec. 24 letter “The Goldilocks level of carbon dioxide”: The writer asserts that “melting all of the remaining ice over Greenland and Antarctica would raise the mean sea level about 225 feet” but does not give us any information where or how he arrived at that “estimate.” Of course it would not matter because the temperature needed to melt all that ice would probably make the earth too hot to be habitable any way.

Since the writer is a man of some educational background, perhaps he can show us some calculations as to the amount of water that is in the ice caps and how he determined it, and how much water it would take to raise the sea level 225 feet. Call me a doubter, but the two should match.
