Abstract: Snow is the primary source of water and streamflow in western North America and supports the water supply for more than one billion people globally. In mountainous regions, accumulated snow extends the downstream delivery of meltwater through the spring and summer when human and ecosystem demands are greatest. It is well established that climate change is expected to shift melt earlier and reduce snow water resources with broad impacts on ecosystem productivity, winter flood risk, groundwater recharge, agriculture and food security, and wildfire hazard. In this talk, I present empirical and model-based evidence of ongoing and projected change in snow water resources in western North America. These changes are disproportionately affecting northern Indigenous communities. I introduce a new project working to increase collective understanding of the impacts of climate change on rivers, fish, and Indigenous communities in Alaska and western Canada. Collaboration with Tribal and First Nation communities, community-based science networks, and an Advisory Council guide the science by facilitating monitoring and informing modeling decisions as part of this project. As cold regions warm and their rivers change, the impacts on people, fisheries, and winter travel routes are unknown. Synthesizing numerous ongoing projects, I will discuss methods by which improved understanding of the possible future changes in mountain hydrology, societal impacts, and potential adaptation strategies are being assessed through close partnership among communities, decision-makers, and scientists from diverse fields of study.
