Caption: Arctic sea ice, 1979-2010, with area graph. The extent of the sea ice varies over the course of a year, being largest just after the winter and smallest after the summer. Comparing the maxima and minima over several years allows trends in ice cover to be followed. Both the minimum and maximum extent of Arctic sea ice have reduced greatly since the middle of the 20th century, providing powerful evidence for global warming due to carbon emissions. Data from the Special Sensor Microwave Imager (SSMI) on a Defense Meteorological Support Program (DMSP) satellite.
