Mexico, Italy and Others See up to Two More Months of Heat Stress than in the 1970s, Study Says

Researchers say one billion more people now face at least one day of extreme heat stress each year as warming lengthens dangerous seasons.

  • A Nature Climate Change study published Monday found one billion more people now face at least one day of extreme heat stress annually, with heat stress expanding in Mexico, Kenya, and Italy over six decades.
  • Fossil fuel burning drives rising temperatures and humidity, which intensify heat stress seasons and make sweating—the body's cooling mechanism—less effective at protecting people from dangerous conditions.
  • Feels-Like temperatures on the ten warmest nights increased 0.32°C per decade, faster than the 0.27°C rise for the ten warmest days, meaning people lack overnight recovery from daytime heat.
  • Lead author Rebecca Emerton of the European Centre for Medium-Range Weather Forecasts says urgent adaptation measures—heat-health action plans, early warning systems, and climate risk assessments—are necessary to protect billions.
  • Projections show some areas face around 50 more days of strong heat stress annually, while affected regions including Southern Europe and Eastern Africa see up to 40 additional days compared with the 1970s.
