6. Date Name of Meeting 6 Usefulness for “the Public” Web-based and transparent “line of sight” between data and conclusions Highly understandable language with graphics that help "tell the story" -of the difference between climate variability and change. -how we can tell the difference between "normal" variability and long- term trends. -examples of the kinds of observed changes and adaptations 8 Regions addressed plus Oceans, Coasts, Urban, Rural, Land use

7. Date Name of Meeting 7 Sectors Water Resources Energy Supply and Use Transportation Agriculture Forestry Ecosystems and Biodiversity Human Health

8. Date Name of Meeting 8 Cross-Cuts Water, Energy, and Land Use Urban Systems, Infrastructure, & Vulnerability Tribal, Indigenous, & Native Lands and Resources Land Use & Land Cover Change Rural Communities Biogeochemical Cycles

9. Date Name of Meeting 9 Responses to Climate Change ? Decision-making support in a “risk-based” framework Assesses progress in response activities -adaptation (preparedness) -mitigation (managing emissions of heat-trapping gases)

10. Date Name of Meeting 10 Observed Temperature Change

11. Date Name of Meeting 11 Projected Temperature Change

12. Date Name of Meeting 12 Observed Change in Very Heavy Precipitation

13. Date Name of Meeting 13 Projected Precipitation Change by Season

14. Date Name of Meeting 14 Water, Northwest and Urban Chapters Key Messages Water related challenges Coastal vulnerabilities Impacts on forests Adapting agriculture Increases in heavy precip, length of dry spells Short term droughts intensify Flooding may intensify Introduction of new risks Infrastructure compromised by interrelated impacts Climate disruptions in one system results in disruptions in other systems Social inequalities affect vulnerability

15. Date Name of Meeting 15 Primary questions What does climate change mean for where you live and operate? What does it mean for your sector? What are the interdependencies across sectors that can amplify risk?

16. Date Name of Meeting 16 Secondary questions What skill sets and information do I need to answer these questions? What are the best strategies to manage these risks? How and when do I implement these strategies?

17. Date Name of Meeting 17 SPU’s climate program Urban Drainage Water Supply Sea Level Rise

18. Date Name of Meeting 18 Climate program objectives enhance knowledge by engaging the science assess impacts and vulnerabilities establish collaborative partnerships strengthen institutions and people mainstream adaptation into decision- making develop portfolios of approaches

19. Date Name of Meeting 19 Engage science, assess vulnerabilities using 40 climate scenarios climate impacts on: – supply and operations – atmospheric rivers – forest fires – timing of fall rains – precipitation thresholds in-city evaluate combined effects of sea level rise + precip enhanced meteorological forecasting

20. Date Name of Meeting 20 Establish collaborative partnerships Seattle Public Utilities San Francisco Public Utilities Commission Metropolitan Water District of So. California San Diego County Water Authority Southern Nevada Water Authority (Vice Chair) Denver Water Portland Water Bureau New York City Department of Environmental Protection Tampa Bay Water (Chair) Central Arizona Project Mission: The Water Utility Climate Alliances provides leadership in assessing and adapting to the potential effects of climate change through collaborative action. We seek to enhance the usefulness of climate science for the adaptation community and improve water management decision-making in the face of climate uncertainty.

21. Date Name of Meeting 21 Strengthen institutions

22. Date Name of Meeting 22 Conclusions Treat climate change as part of risk management in decision-making Engage in ongoing enhance of knowledge Assess impacts and vulnerabilities Bring adaptation/resilence into decision-making Build collaborative partnerships Strengthen institutions and people
