Europe's ongoing heatwave has become one of the continent's deadliest climate disasters of the year, with preliminary estimates indicating that nearly 5,000 people have died as a result of record-breaking temperatures.
France, Belgium, and the Netherlands have recorded the highest number of heat-related fatalities.
Initial mortality analyses show around 3,700 excess deaths were registered between 20 and 28 June across the three countries alone, with experts warning that the overall death toll is expected to rise as additional data from other European nations becomes available.
France has been the hardest-hit country, with health authorities estimating approximately 2,025 excess deaths linked to the heatwave. Most victims were over the age of 45, while deaths occurring at home surged by 91 percent during the hottest week.
Belgium recorded around 1,200 additional deaths, including more than 500 people aged over 85, as well as nearly 180 fatalities among individuals under 65, highlighting that extreme heat poses a serious risk across multiple age groups.
In the Netherlands, authorities estimate approximately 480 excess deaths, with the majority involving elderly residents.
The extreme temperatures have also fueled widespread wildfires across Portugal, Spain, France, and Greece, forcing thousands of residents to evacuate their homes while causing power outages, transportation disruptions, and mounting pressure on healthcare systems.
Several countries recorded temperatures exceeding 40°C, with multiple locations breaking historical June temperature records.
Scientists say the severity of the current heatwave would have been "virtually impossible" without human-induced climate change, warning that such extreme weather events are becoming more frequent, longer-lasting, and increasingly dangerous.
The ongoing crisis underscores the growing impact of climate change across Europe. According to the World Health Organization (WHO), more than 200,000 people have died from heat-related causes across Europe over the past four years, with many of those deaths considered preventable through stronger preparedness and response measures.
