A computer-generated map of Greenland as it would be if viewed from space from a region over north America. The ice cap of Greenland is mostly coloured white which represents ice, although around its edge there is a pink-shaded region which corresponds to the area of the ice cap that melted in the summer of 1992, and above this pink region is a red region which represents the area of the ice cap that melted in the summer of 2005. So from 1992 to 2005 the area of the ice cap that melts in summer has greatly increased. In addition there is a contour line showing the altitude on the ice cap of 2000 m. The red 2005 melting area is at a higher altitude than this.
