These pages are designed to provide our tribal leaders and staff with information on how climate change may affect their tribe’s natural resources during the 21st century. Scientific research and data listed here project the effects of climate change in the Columbia Basin, including overviews of the issue and its effects, and projected impacts to water and terrestrial resources and fish and wildlife. Also listed are tools and recommendations to assist with climate change vulnerability assessment and adaptation. The threat of climate change is significant to the water, land, and native species of the Columbia Basin. The members of the Columbia Basin Indian Tribes are uniquely vulnerable to these effects because they are intimately tied to their traditional hunting and fishing grounds to gather their “first foods”, which have immense importance to their economic, cultural, and spiritual well-being.

Projections (Data) for Future Climate Change Scenarios
A new set of hydrologic climate change scenario projections were completed at the University of Washington in partnership with regional water management agencies in the Fall of 2017. The Columbia River Climate Change Project includes results from low (RCP4.5) and high (RCP8.5) emissions scenarios and multiple global climate models, downscaling methods, and hydrologic models in order to produce a robust range of future projected changes to river flows at 396 different sites throughout the Pacific Northwest. We recommend that tribal staff use these updated projections for hydrologic or water resource studies that require estimates of future river flows.
Boise Aquatic Sciences Lab, US National Forest Service (2013) NorWeST Stream Temp Regional Database and Model. The NorWeST webpage hosts stream temperature data and climate scenarios in a variety of user-friendly digital formats for streams and rivers across the western U.S. The temperature database was compiled from hundreds of biologists and hydrologists working for >100 resource agencies and contains >150,000,000 hourly temperature recordings at >20,000 unique stream sites. Those temperature data were used with spatial statistical network models to develop 30 historical and future climate scenarios at 1-kilometer resolution for >1,000,000 kilometers of stream.
