The report identifies significant risks to public health, ecosystems, and infrastructure in California. Residents in the U.S. Southwest are increasingly exposed to Valley Fever due to airborne fungal spores during dust storms. Heatwaves are linked to adverse health outcomes, including preterm and early-term deliveries in urban areas. Marine heatwaves, such as those tracked in the California Current, disrupt marine ecosystems, affecting biodiversity and fisheries. These cascading impacts highlight the vulnerability of interconnected systems to climate change.
