If the icecap that covers Greenland were to melt completely, sea levels worldwide would rise by an average of seven metres. |
Since 1950 numerous core samples have been taken from the Greenland icecap and used to study climatic changes over tens of thousands of years. |
Near the Phoenix Lander, on the edge of the Martian Arctic icecap, there are now two scoop marks in the ground. |
