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.
