Visualizing Sea Level Rise
We found that the total water area of the earth's oceans and seas is 133,968,400 mi2 (346,976,563 km2).
Our conversion of the ice volume to water volume of the ice sheets was produced by multiplying the ice volume by the density conversion factor:
Greenland:
624,766 mi3 x 0.9 = 562,289 mi3
Antarctica:
7,033,274 mi3 x 0.9 = 6,329,947 mi3
Sea level estimates were calculated by dividing the water volume of the ice sheets by the total surface area of the oceans and seas:
|
Greenland: |
562,289 mi3 / 133,968,400 mi2 = 0.0042 miles = 22 feet |
|
Antarctica: |
6,329,947 mi3 / 133,968,400 mi2 = 0.0472 miles = 249 feet |
