[edit] Summary

Description	September ice extent from 1979 to 2007 shows an obvious decline. The September rate of sea ice decline since 1979 is now approximately 10 percent per decade, or 72,000 square kilometers (28,000 square miles) per year. This shows the historic minimum of September 2007, which surprised scientists.
