Extreme heat poses significant risks to California's most vulnerable populations, including low-income households, outdoor workers, and people experiencing homelessness. Health impacts range from heat-related illnesses to increased hospitalizations for heart and mental health conditions. The economic toll is also substantial, with billions lost in wages, agricultural disruptions, and power outages. Wildfires, exacerbated by high temperatures, further strain resources. The state's efforts aim to reduce these risks by improving community resilience and infrastructure, but the challenges remain immense as temperatures continue to rise.
