Greenland lost enough ice in last 2 decades to cover entire US in 1.5 feet of water
The Arctic is warming faster than anywhere else on the planet, and the toll on Greenland's massive ice sheet is becoming achingly clear.
According to new satellite data compiled by Polar Portal, a collection of four Danish government research institutions, Greenland has lost more than 5,100 billion tons (4,700 billion metric tons) of ice in the past 20 years — or roughly enough to flood the entire United States in 1.6 feet (0.5 meters) of water.
