A new record minimum for arctic sea ice

Posted by: JeffMasters, 3:07 PM GMT on November 18, 2009
Arctic sea ice reached a new record minimum during the first half of November, according to data from the National Snow and Ice Data Center (Figure 1). The record low ice extent this month is the first extended period of record minimum arctic sea ice since 2007. The new record minimum suggests that the gains in ice seen over the past two years were probably a temporary fluctuation due to normal year-to-year variability in the weather, and that the long-term arctic sea ice decline observed since the 1970s is continuing.
