Note: The extent of the summer sea ice in September 2007 reached a historical minimum, 39 % below the climatic average for the first two decades of satellite observations (red line)
The weather conditions that summer were dominated by clear skies. Continuous warm winds blew the ice towards the coast of Canada-Greenland and out into the north-east Atlantic, where it melted.
Geographical coverage: Arctic and the north pole
