Projections of Changing Climatic ConditionsRegionWestObserved 20 th CenturyClimateWarmer and generally wetter.• Increased T; up to 2-5 F (1-3 C).• Increased P; in much of region, up to50% in some areas.Highly variable climate withexceptionally wet & dry periods.Length of snow season decreased by16 days in CA & NV. Extreme pptevents have increased.Projections for 21 stCenturyContinued warming & increasedprecipitation.• Increased T: 3-4 F (2 C) by2030s, 8-11 F (4.5-6 C) by 2090s.• Increased P; in winter, esp. in CA.More extreme wet and dry years.PacificNorthwestWarmer and wetter.• Increased T: 1-3 F (0.5 – 1.5 C).• Increased P: 10% (on ave.); 30-40 % ineastern WA, no.ID.Significant recurring patterns of yearto-yearvariability.• Warm, dry years with light snowpack,low streamflows.• Cool, wet years with heavy snowpacks,high streamflowsMuch greater average warmingover the region.• Increased T: 3 F (1.5 C) by2030s, 5 F (3 C) by 2050s.Wetter on ave. across region.• Increased ppt. in winter.• Same or decreased ppt. insummer.From: Furniss et al., 2010.
