Earth – Following a Polar Ice Melt
Earth as it would appear should the Greenland and Antarctic ice sheets melt, raising ocean levels by an estimated 67.5 meters (~221.5 ft). The Greenland ice sheet is estimated to contribute 7 meters to global ocean levels. The Antarctic ice sheet would contribute 60 meters if fully melted. Additional glaciers and ice caps in the margins of Greenland and Antarctic peninsula would contribute an additional 0.5 meters. Roads were added for reference.
