European Heatwave Excess Deaths (Summer 2025)

Summer 2025 heatwaves across southern and central Europe caused over 10,000 excess deaths, a toll 30% higher than the 2024 seasonal average, overwhelmingly among the elderly in Spain, Italy, Greece, and France. With interior Spain hitting 47-48°C, the event triggered power grid failures and overwhelmed healthcare systems, leading scientists to attribute its frequency to climate change—now expected every 3-5 years. This severity surpasses #6 European Heatwave Excess Deaths in direct mortality, though both share similar attribution.
