Sea levels have been higher in the past due to melting ice sheets. If the Greenland ice sheet melts sea level would rise 7 meters, and if both the Greenland and West Antarctic ice sheets melt sea level would rise 13 meters. A full melt of the Greenland, West Antarctic, and East Antarctic ice sheets could raise sea levels by 73 meters according to evidence from foraminifera used to determine ancient ice volumes.

1. Has sea level
been higher in the past?
What happens to Chapter if our ice sheets melt?
Current sea level +7m (Greenland)
+13m (Greenland + WAIS) How do we work out
+73m (Greenland + AIS)
ancient ice volumes?
