Currently the total sea level rise is about 3 millimeters per year (about 1/8 of an inch per year). Of that amount, about one-third comes from Greenland and Antarctica, one-third from glaciers like those in Alaska or the Himalayas, and one-third from the expansion of seawater as it warms. In the future, we expect Greenland and Antarctica will contribute larger amounts.
While a growing Greenland glacier may seem like good news, there’s no evidence it means global warming is slowing down.
The Jason-2 mission provided unique insights into ocean currents, sea level rise and climate change for 11 years.
Data from the mission show water weight gain across the U.S. Midwest and rapid weight loss from Greenland's melting ice.
