In the future, scientists expect Greenland and Antarctica will contribute larger amounts than current rates. By 2100, the latest estimates of sea level rise contributions from Greenland and Antarctica sum up to about 1 meter (about 3 feet), but totals may be as high as 2 meters (over 6 feet). By 2300, total sea level rise from those ice sheets may be as high as 5 meters (about 16 feet).
