Chugach Climate Vulnerability Assessment (CVA)

Chugach Climate Vulnerability Assessment

In collaboration with the Scenarios Network for Alaska and Arctic Planning (SNAP) and the UAA Institute of Social and Economic Research (ISER), Chugach National Forest (CNF), and the US Forest Service, the Landscape Ecology Program helped conduct a climate vulnerability assessment (CVA) for the Chugach region. CVAs use climate projections and future landscape condition models to evaluate potential ecological and socioeconomic effects of climate change at regional scales. In the Chugach assessment, projections were made for a range of modeled data, including a baseline time period (1971-2000), the current decade (10’s), and future decades (2020s, 2040s, and 2060s). These data provided measurements of change as they are likely to manifest themselves in and around the Chugach National Forest. SNAP provided data on the effects of climate change on the following environmental factors: mean and extreme July and January temperature; mean and extreme July and January precipitation; timing of thaw and freeze; length of unfrozen season; and estimated snowline. In addition, SNAP provided information from the published literature regarding other potential climate-linked changes, including those associated with the Pacific Decadal Oscillation (PDO), ocean acidification, and storm frequency and intensity.
