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.

Mexico, Italy, others see up to two more months of heat stress than in 1970s: Report
Global heat stress is intensifying, with regions like Mexico and Kenya experiencing one to two extra months of dangerous heat annually. New research reveals that extreme temperatures, heat stress days, and tropical nights are becoming more frequent and severe due to fossil fuel burning.
Heat stress rises by up to two months in Mexico, Kenya, Italy, study finds
A Nature Climate Change study finds heat stress is intensifying, lasting longer and spreading into new regions. The findings underline rising risks from humid heat and the need for stronger adaptation and emission cuts.

Mexico, Kenya, Italy and other nations around the world are experiencing between one and two months more thermal stress than several decades ago, according to a new research published on Monday, and in some areas the increase is even greater.
