Extreme heat more deadly than floods, earthquakes and hurricanes combined, finds Swiss Re’s SONAR report

Up to half a million people globally succumb to the effects of extreme heat each year, according to recent scientific research, exceeding the combined impact of floods, earthquakes and hurricanes. This places the observable increase of extreme heat events among the most important emerging risks, according to Swiss Re’s 2025 SONAR report. The study highlights how this peril reaches beyond the human toll, mapping its effects across industries such as the energy and telecommunications sectors.
