Melting Ice Sheets 19 + 23 ft ( 7 meters ) + 177 ft ( 54 meters ) Source: IPCC
Set 3 www.climatefresk.org 19 Greenland and Antarctica are ice sheets (or continental glaciers). If they were to completely melt, they will cause the sea level to rise by 23 feet ( 7 meters) for Greenland and 177 feet ( 54 meters) for Antarctica. During the last ice age, ice sheets were so much larger that the sea level was 390 feet ( 120 m) lower than today.

It's a bit technical, but the blue part of the map of Antarctica on card 19 represents a gain in mass due to an increase of precipitations. The red part represents a loss in mass. In total, Antarctica is losing mass.
