  11. Impact Challenges • Change implies permanency, a final level, a stable result • Variability ? ability to predict seasonally and spatially. • Farm migration • Deprivation (psychological stresses) • Mass ice wasting • ocean model life span • governance models for tri-lateral action for one continent • .

  12. To find new ways to link ideas

  13. connect to absence of mitigation
