2. The Various Roles of Decision Support Tools National Academy of Sciences: America’s Climate Choices: Adapting to the Impacts of Climate Change (2010)

3. Classification of Decision Support Tools – Guidebooks (CRiSTAL, CIG/ICLEI/King County, StormSmart Coasts) – Climate impact maps & scenario visualization tools (CIG maps, NOAA hazard assessment tool & SLR visualizer, OSU ENVISION, COAST, NatureServe VISTA) – Databases/Clearinghouses (Climate Adaptation Knowledge Exchange, WeAdapt) – Engagement strategies & methodologies (Coast- Smart Communities, Climate Witness, Scenario Planning)

9. Considering Alternate Approaches: Benefits vs. Limitations of formal Scenario Planning Approach Major Benefits: Consistent with conventional risk management approaches Allows for an organization to explicitly “test decisions under a variety of plausible futures.” (D. Weeks et al, Parks Science, Aug. 2011) Major Limitations: Requires “availability of technical and financial capacity to handle scenario information” (S. Dessai et al, Global Environmental Change, 2005) Requires significant investment of time by staff
