California heat waves lead to deaths, financial losses

California heat waves lead to deaths, financial losses

Recent heat waves in California have resulted in hundreds of deaths and billions in economic losses over the past decade, a new report by the state insurance department reveals.

Levi Sumagaysay reports for CalMatters.


In short:

  • Seven heat events from 2013 to 2022 killed nearly 460 people and caused $7.7 billion in economic damage.
  • Effects include lost wages, productivity declines, agricultural disruptions, and infrastructure damage.
  • Low-income communities and minority groups face the highest heat-related death rates.

Key quote:

“It’s really important to understand that heat is a silent killer.”

— Michael Mendez, assistant professor of environmental planning and policy at UC Irvine

Why this matters:

Rising temperatures are more than just a summer inconvenience. They’re a serious threat to public health and the economy. Vulnerable populations, such as the elderly, children, and those with pre-existing health conditions, face the greatest risks. Hospitals and emergency services are stretched thin during extreme heat events, dealing with a surge in heat-related illnesses.
