5. WORKSHOP: LESSONS FROM THE 2007 ICE MINIMUM Agenda III. Lessons from 2007: Gaps and Needs for Understanding Arctic Change 8:30 a.m. Welcome, review of Wednesday discussions, and today's goal Martin Miles, ESARC Jean-Claude Gascard, Université Pierre et Marie Curie 9:00 a.m. Presentations and Discussion focused on: ·        What lessons can be learned from 2007 to guide future science activities? ·        What is needed in additional capacity and plans for observing the 2008season (and beyond) to improve our understanding, and response strategies to arctic-system change? Specific needs relating back to the AON and Lagrangian workhops? 10:00 BREAK 10:30 a.m. Conclusions, recommendations, and next steps: ·        Given the unexpected changes witnessed in 2007, what are the priorities for observing, understanding, and responding to change activities? ·        How should these priorities be addressed? What are the next steps? Discussion of workshop products (synthesis papers and other products), next steps, and writing assignments

17. WORKSHOP: LESSONS FROM THE 2007 ICE MINIMUM 2. Presentations and Discussion on WGs 1) Through modeling and data analysis activities – including retrospective analyses of the long-term observational record – how well do we understand 2007? What are the gaps in observing and understanding sea-ice loss and related changes? 2) What do modeling and data analysis tell us about overall system behavior that is relevant for predicting sea ice – on seasonal to decadal time scales – and related arctic changes? How does the “tipping point” concept factor in? 3) What are the science / policy / human implications of the unexpected, faster-than-forecast changes? What does this mean for responding to change?

19. WORKSHOP: LESSONS FROM THE 2007 ICE MINIMUM Synthesis of 2007:Discussion Themes 3) What are the science / policy / human implications of the unexpected, faster-than-forecast changes? What does this mean for responding to change?
