What if all land ice melted?

If all land ice—including the Antarctic and Greenland ice sheets and mountain glaciers—melted, global mean sea level would rise about 70 meters according to the USGS; some sources give about 65 meters. This is a long-term hypothetical scenario, not a near-term forecast. The claim that over 12% of land would disappear needs qualification: the flooded area depends on topography and how “land” is defined. The illustration is AI-generated.
