What will the rivers of the Pacific Northwest look like in the future? Will they be stable or unstable? Will the waters be cold and clear or warm and muddy? Will they have salmon or other species? These questions motivated our two-year study of climate warming effects on headwater streams draining the Cascade Mountains. Using a novel combination of snow, geohydrology, and sediment transport models we assessed the vulnerability of stream channels to changing peak streamflow. Our snow modeling shows that with just a 2°C warming, snowfall shifts to rainfall at all elevations, peak snowpacks occur over two months earlier, and snowpacks are reduced by over half of historical values. Our geohydrology modeling shows that...

Tribal communities’ traditions, identities, and economies rely heavily on local natural resources, making tribes especially vulnerable to climate change impacts, including changes in seasonal patterns and the potential loss of culturally and economically important species. The goal of this project was to build tribal capacity in the Pacific Northwest to successfully plan for and adapt to the effects of climate change. The funds associated with this project supported the Affiliated Tribes of Northwest Indians (ATNI) Tribal Leaders Summit on Climate Change held on March 10-11, 2015 in Portland, Oregon. The summit gathered tribal leaders to discuss climate change impacts; share tribal strategies, plans, and policies;...
