Alaska glaciers account for less than one percent of the Earth’s area currently covered by ice, but a recent study suggests this ice is melting quickly. Airborne laser altimetry used to measure changes in volume and area of 67 glaciers in Alaska (including 14 glaciers from the Harding Icefield) estimates about 40 cubic miles of ice may be melting annually. This study further calculated that during the last decade, Alaska’s melting glaciers contributed eight percent of the observed annual rise in global sea level.
