Abstract:

A scenario of future climate change in the Pacific Northwest (PNW), derived from global climate model projections, is presented to facilitate discussion about the regional implications of climate change. Under this scenario, the PNW would experience warmer, wetter winters and warmer, drier summers, on average. Annual average temperatures would increase 1.1C (2F) by the 2020s and 2.5C (4.5F) by the 2050s. Sea level would generally rise 7 cm (3") by the 2020s, 20 cm (8") by the 2050s; the local rate of increase would be exacerbated or ameliorated by local land subsidence or uplift. Climate change will be manifested most directly through changes to the region's hydrologic cycle. Changes in water availability and in the timing of supply will subsequently impact all aspects of the region. This paper explores both the regional vulnerabilities to climate change and the opportunities such change may afford the PNW, focusing on impacts (both positive and negative) on the following eight sectors: hydrology and water resources; forests and rangelands; marine and aquatic ecosystems; coastal ecosystems and activities; agriculture and grazing lands; human health; energy production and utilization; and urban centers.
