Sea Ice Outlook: 2008 July Report
Summary
The outlook for the pan-arctic sea ice extent in September 2008, based on July data, indicates a continuation of dramatic arctic sea ice loss. The July Sea Ice Outlook report is based on a synthesis of 22 individual projections utilizing a range of methods. Projections based on July data show no indication that a return to historical sea ice extent will occur this year.
Sea Ice Outlook: 2008 June Report
The outlook for the pan-arctic sea ice extent in September 2008, based on June data, indicates a continuation of dramatic sea ice loss. The June Sea Ice Outlook report is based on a synthesis of 17 individual projections, utilizing a range of methods. Projections based on June data are similar to those of the May report, with no indication that a return to historical sea ice extent will occur this year.
Sea Ice Outlook: 2008 May Report
The May Sea Ice Outlook report for the September 2008 sea ice extent is based on a synthesis of 19 individual outlooks from the international arctic science community. The outlook for the pan-arctic sea ice extent in September 2008 indicates a continuation of the recent trend of sea ice loss.

Sea Ice Outlook: 2012 Post-Season Report
POST-SEASON REPORT
HIGHLIGHTS & TAKE-HOME POINTS
The average arctic sea ice monthly extent for September 2012 was the lowest observed in the satellite era at 3.6 million square kilometers, based on National Snow and Ice Data Center (NSIDC) estimates—50 % lower than the 1979-2000 average of 7.0 million square kilometers.
This value compares to the previous low value in 2007 at 4.3 million square kilometers and 4.6 million square kilometers in 2011.

Sea Ice Outlook: 2012 August Report
Pan-Arctic Full Outlook: Brief Update
OVERVIEW OF RESULTS
With 23 (thank you!) responses for the Pan-Arctic Outlook (plus 5 regional Outlook contributions), the August Sea Ice Outlook projects a September 2012 arctic sea extent median value of 4.3 million square kilometers, with a range of 3.9–4.9 (Figure 1). The quartiles for August are 4.1 and 4.6 million square kilometers, a narrow range given that the uncertainty of individual estimates is on the order of 0.5 million square kilometers. The consensus is for continued low values of September 2012 sea ice extent.
Sea Ice Outlook: 2012 July Report
Summary
With 21 responses for the Pan-Arctic Outlook (plus 5 regional Outlook contributions), the July Sea Ice Outlook projects a September 2012 arctic sea extent median value of 4.6 million square kilometers (Figure 1). The consensus is for continued low values of September sea ice extent. Individual responses are based on a range of methods: statistical, numerical models, comparison with previous rates of sea ice loss, composites of several approaches, estimates based on various non-sea ice datasets and trends, and subjective information.

Sea Ice Outlook: 2012 June Report
With 19 responses for the Pan-Arctic Outlook (plus 6 regional Outlook contributions), the June Sea Ice Outlook projects a September 2012 arctic sea extent median value of 4.4 million square kilometers, with quartiles of 4.3 and 4.7 million square kilometers (Figure 1). This compares to observed September values of 4.6 in 2011, 4.9 in 2010, and 5.4 in 2009. Both the 2012 quartile values and the range (4.1 to 4.9) are quite narrow. The 2012 June Outlook differs from all previous Outlooks in that there are no projections of extent greater than 5.0.
