7 Key Messages

5. Climate change is already affecting the oceans and the socio-ecological systems that depend on them
Friedland et al., Pathways Between Primary Production and Fisheries Yields of Large Marine Ecosystems

6. 2. Technical advances in existing and new observation networks are improving our understanding of key ocean processes, but our ability to project future ocean conditions at seasonal to multi-decadal time scales is still incomplete
Guiding principles for forecasting teams;
Predictions at decadal time scales not yet possible in all regions;
Chinese Academy of Sciences Center for Mega Science.

7. 3. Despite significant gaps, our understanding of socio-ecological systems has improved sufficiently to enable us to contrast the ecological and societal impacts of different future scenarios
Karp et al., in press: ‘Accounting for shifting distributions and changing productivity’ key steps of a climate-informed science-to-management system

8. South African seabird species; blue crabs in the Bering Sea;
4. Some marine organisms exhibit a capacity to adapt to climate change, but there are energetic and physiological costs, as well as limits
Examining variations in adaptive responses to a full suite of environmental stressors within the socio-ecological system;
South African seabird species; blue crabs in the Bering Sea;

9. 5. Options available for societal adaptation are more limited if current trends of greenhouse gas emissions continue
Coupled socio-ecological models used to evaluate the trade-offs associated with different societal responses

10. 6. Tactical and strategic opportunities for societal adaptation to climate change have also been revealed through engagement with institutions and dependent communities eager to plan their own future
Guidance to governance: case studies where researchers engaged coastal communities in efforts to develop effective climate adaptation strategies

11. 7. Adaptive management frameworks are urgently needed to address climate-driven policy issues
Suites of key research activities that can be adopted to improve the adaptation of management frameworks to develop climate-informed policies

12. Integrated multidisciplinary research programs are appearing across the globe in response to the societal need for information on the impacts of climate change on the world’s oceans.
