How much land floods if the sea rises, or seafloor dries if it falls?
The share of land flooded by a rise in sea level, or of seafloor laid dry by a fall, from ETOPO 2022 terrain.
Today’s land lost
11.1 %
If the sea rose by 66 m, 11.1 % of today’s land would be underwater, and 26 % of Earth’s surface would still be land.
- Land left
- 26 %
Try an example
How it is worked out
flooded: land_share = interp(LAND, change_m)land_lost = (LAND(0) - land_share)/LAND(0), LAND(0) = 0.29225348 (ETOPO 2022)Where the numbers come from
Keep in mind
Assumes the ice sheets melt as the sea rises (their beds count as land once uncovered); static flooding of today’s terrain, no tides or rebound.
