In July 2007, the Climate Impacts Group (CIG) launched an unprecedented assessment of climate change impacts on Washington State. The Washington Climate Change Impacts Assessment (WACCIA) involved developing updated climate change scenarios for Washington State and using these scenarios to assess the impacts of climate change on the following sectors:
- human health
- hydrology and water resources
- urban stormwater infrastructure
Adaptation in each of these sectors was also discussed. Research partners included Washington State University and Pacific Northwest National Laboratory. The assessment was funded by the Washington State Legislature through House Bill 1303.
