National Snow and Ice Data Center: Arctic sea ice extent for June 2008 is close to that for 2007, which went on to reach the lowest minimum since at least 1979. More notably, however, satellite data indicate that melt began significantly earlier than last year over most of the Arctic Ocean. The large area of the Arctic Ocean covered by first-year ice (described in our June analysis) coupled with the early onset of melting may mean more rapid and more severe summer ice retreat than last year.
