If Greenland melted into the sea, how much would the water level rise?

of Greenland the continental glacier has 2.74 million gigatons of ice. A gigatonne means a billion tonnes.

There is so much ice that if it all melted, the surface of the oceans would rise on average about 7.4 meters.

Greenland’s ice cover is currently decreasing by melting from the surface and breaking off from the edges. The icebergs that break off the edges then melt in the sea.
