Statewide Summary Report: California's Fourth Climate Change Assessment

The Fourth Assessment included, for the first time, the development of Statewide Reports covering critical topics for California. These summary reports include Climate Justice, Tribal and Indigenous Communities within California, and California’s Ocean and Coast. Finally, the Statewide Summary Report provides an overview of the findings and context for the entire Fourth Assessment.
