What might be the calculated sea surface rise from a total Greenland melt? http://en.wikipedia.org/wiki/Sea_level_rise Volume of ice in km^3 /surface area ocean km^2 = rise in km. S.A. of earth is 510 x 10^6 km^2. ocean is 71% of S.A., or 361 x 10^6 km^2. http://en.wikipedia.org/wiki/Earth Greenland area is 2.166 x 10^6 km^2. 81 % is ice/water or 1.75 x 10^6 km^2. http://en.wikipedia.org/wiki/GreenlandThe key missing ingredient is average ice depth. perhaps 2-3 km at deepest, with central basin of about 1000 ft below sea level. If 1 km av depth, one gets 4.1 meter sea level rise. For .5 km av depth, one gets 2 meter sea level rise. One contained reference mentions 7 meters. http://en.wikipedia.org/wiki/Greenland But wouldn't one also have to consider caveat of part of melt occupying Greenland basin, leaving an archipelago?
