80% of Greenland is covered by ice ranging in thickness between 6600-9800 ft.
If all of that melted....
(1) Oceanic Surface Area: 3.6e8 km^2
(2) Greenland Land Area = 2,166,086 km^2
(3) Greenland Ice Area = 80% * (2) = 1,732,869 km^2
(4) Greenland Ice Thickness Average = 2.5 km
(5) Greenland Ice Volume = (3)*(4) = 4,331,063 km^3
(6) Volume ratio of ice to water 1.09:1
(7) Water Volume of Greenland ice (5) / 1.09 = 3,973,452 km^3
(8) Rise of Ocean = (7) / (1) =
36 feetThis would be a huge problem!
