Arctic ice cover extent
Riccardo Pravettoni, UNEP/GRID-Arendal
The greatest reduction in
Arctic summer sea ice extent since satellite observations
began occurred in 2007, with the following two years
experiencing the second and third biggest reductions.
The Greenland ice sheet is currently
losing more than 250 cubic km a year – faster than can
be explained by natural melting.
