CA ACR109

Legislature recognizes extreme heat as a serious and urgent threat to public health, infrastructure, agriculture, and water and energy security in California.

Calls on state agencies and departments to invest resources in increasing resilience to extreme heat with priority given to at-risk and vulnerable communities.

Directs agencies to develop strategies to mitigate urban heat island effects, enhance building resilience in existing housing and commercial stock, and evaluate effectiveness of protective measures against rising temperatures.

Notes extreme heat is the leading cause of weather-related mortality in the United States, with California's Fourth Climate Change Assessment projecting costs of $50.3 to $84.8 billion annually by 2050 and 6,700 to 11,300 premature deaths per year by midcentury.

Emphasizes disparate impacts on low-income communities, communities of color, farmworkers, children, and unhoused populations who lack adequate cooling, green infrastructure, and heat protection resources.
