Climate diagnostics of future water resources in BC Watersheds : Climate diagnostics of future water resources in British Columbia Watersheds

About PCIC The mission of the Pacific Climate Impacts Consortium is to quantify the impacts of climate variability and change on the physical environment in the Pacific and Yukon regions. [...] Most of the internal variability comes from the global climate model, which is the source of our best estimate of the natural variability in the real climate system. [...] The influence of internal variability on estimates of the projected change in the climatological values of the hydrologic components in the major watersheds of British Columbia is estimated to be less than 6% for both snow accumulation and runoff. [...] The impact of the climate change signal in the 2050s decreased the annual mean value of the snow accumulation by about 2% in the Upper Peace, 6% in the Upper Columbia, and a decrease of almost 20% for the entire Columbia Basin, relative to projected mean annual climatology. [...] The larger context for this study is a project of targeted research at the Pacific Climate Impacts Consortium (PCIC) that is directed to the following watersheds: the Upper Peace, the Upper Columbia, and the Campbell.
