Communicating Changes in Arctic Environment
  • The international Arctic Sea Ice Outlook
  • A community-wide summary of the expected
    September Arctic sea ice minimum.
  • The Arctic Report Card
  • A concise, scientifically credible and accessible
    source of information on recent changes in the
    Arctic.
  • Future of Arctic Sea Ice and Global Impacts
  • Summarizes important recent Arctic science
    results for a broader broader audience, beyond
    the science literature.

Sea Ice OutlookA community-wide summary of
expected September Arctic sea ice minimum.
  • Reports issued monthly throughout summer.
  • Synthesize community-wide estimates
  • Scientific rationale of the range of estimates of
    expected minimum of sea ice
  • Not formal predictions for Arctic sea ice extent

1979-2000
2009
  • All Outlook projected values for September 2009
    were less than the observed value
  • But most were within the range of uncertainty

5
Sea Ice Extent
  • Although there was more sea ice in September 2009
    than in 2007
  • The fall freezeup into November for 2009 matches
    that of 2007.

6
The slow freezeup that was seen in satellite
observations of Arctic sea ice extent is also
seen in 2009 photos
