21.  Community-wide summary of expected September sea ice extent Monthly reports throughout summer Synthesize community- wide estimates Scientific rationale for range in estimates Not formal predictions 21

22.  26 groups participated  Sept 2011 minimum was 4.6 million km 2 Outlooks based on May data averaged 4.7 million km 2 Outlooks based on June data averaged 4.6 million km 2  Good performance of outlooks due in part to year-to-year persistence of ice conditions  2011 minimum depended more on initial late spring conditions than extreme weather conditions 22
