The short version

  • Four consecutive summer heatwaves across Western Europe have caused at least 35,000 provisional excess deaths, with elderly populations suffering disproportionately.
  • Credit rating agency S&P warned that increased claims from heat-related deaths, health complications, wildfires, and droughts could weigh on insurer earnings and increase premiums for customers.
  • Total fatality figures are expected to rise significantly once August data is consolidated and additional nations release mortality statistics.
