Puget Sound State of Knowledge Report

State of Knowledge Report – Climate Change in Puget Sound

State of Knowledge: Climate Change in Puget Sound is a comprehensive synthesis report summarizing relevant research on the likely effects of climate change on the lands, water, and people of the Puget Sound region.

Part of the Climate Impacts Group’s “State of Knowledge” series, this report details observed and projected changes for Puget Sound’s climate, water resources, forests, species and ecosystems, coasts and ocean, infrastructure, agriculture, and human health in an easy-to-read summary format designed to complement the foundational literature (peer-reviewed science, community and agency reports, and publicly available datasets) from which it draws. The report also describes local climate change risk reduction activities and highlights data resources available to support local climate adaptation efforts.

The work was funded by the U.S. Environmental Protection Agency via the Puget Sound Institute at UW Tacoma, the National Oceanic and Atmospheric Administration, and the State of Washington.
