Global Temperature Variation
NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. This time series shows the progression of changing global surface temperatures from 1884 through 2012. (From NASA Goddard SVS)› key points
Arctic Sea Ice
This 40-second animation shows the annual Arctic sea ice minimum area from 1979 to 2012, with a graph overlay. The 2012 Arctic minimum, reported on Sept. 19, was 1.32 million square miles (3.41 million square kilometers) -- the smallest in the satellite record.› key points
Daily Sea Ice, with Winds
Early in the month of August, 2012, storms in the Arctic affected the motion of the sea ice north of Siberia and Alaska. This animation shows the motion of the winds over the Arctic in conjunction with seasonal melting of the Arctic sea ice from August 1 through September 13, 2012, when the NASA scientists determined that the sea ice reached its annual minimum extent. The surface winds, shown my moving arrows, are colored by the velocity. Slower winds are shown in blue, medium in green and the fast winds are shown in red.
