  4. Minimum Arctic Sea Ice Extent 7.50 Ice Extent (million km2) 3.75 Year NSIDC, 2012

  5. September Sea Ice Volume

  6. Minimum Arctic Sea Ice VolumePIOMAS Ice Volume (1000 km3) Year

  7. Minimum Arctic Sea Ice VolumePIOMAS 16.0 Ice Volume (1000 km3) 4.0 Year

  8. Minimum Sea Ice Extent Projections Most models project at least some September sea ice through the end of the century Based on Holland, Bitz, Tremblay, GRL 2006

  9. Ice Albedo Feedback

  10. Consensus on Likely Location of the Last Sea Ice Area Observations – Ice Age CCSM

  11. Sea Ice Loss Pattern

  12. Sea Ice Loss Pattern THIN THICK

  14. Part I Future Sea ice Condition from Low Resolution Climate Models • Over 30 participating GCMs • Diagnostics: • Sea Ice Extent • Sea Ice Thickness • Snow Depth • Simulations • Historical period: 1979-1999 • 21st century climate: 2000-2010, 2010-2020,…, 2090-2100

  15. Part II Future Sea ice Condition from High Resolution Regional Models • MITgcm • Diagnostics: • Sea Ice Extent • Sea Ice Thickness • Snow Depth • Simulations • 21st century climate: 2000-2010, 2010-2020,…, 2090-2100
