*Dramatic NASA Video of Melting Arctic Sea Ice* The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005.
The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. This animation, produced by NASA, shows the dramatic change in arctic sea ice between Sept. 21, 2005 and Sept. 14, 2007.
