Europe is contending with a severe heatwave, marked by overwhelmed hospitals, unprecedented "red weather alerts," and an estimated few hundred fatalities, including children. Paris has implemented a ban on alcohol sales and public consumption in an effort to mitigate public health risks during the extreme temperatures.

At least 101 million Europeans have experienced temperatures exceeding 35 degrees Celsius (95 degrees Fahrenheit) for multiple days. Scientists have linked the intense heat, which has broken records in Britain, France, Spain, and Switzerland, to climate change. The Netherlands issued its first-ever red alert for heat, while Germany anticipated temperatures reaching 40 degrees Celsius (104 degrees Fahrenheit) over the weekend, leading to event cancellations and travel advisories.

French and British health services reported a significant increase in emergency calls and hospital visits attributed to heat-related illnesses. "We are reaching a saturation point in hospital facilities," stated Paris police chief Patrice Faure, noting a continuous rise in hospitalizations. France observed a fourfold increase in emergency room visits for heat-related reasons, alongside a surge in cardiac arrests. Similarly, the London Ambulance Service reported that the extreme heat on Wednesday resulted in the highest number of life-threatening emergency calls in a single day.

The UN's climate chief, Simon Stiell, commented that the heatwave, exacerbated by infrastructure unsuited to high temperatures, bears the "fingerprints of the climate crisis." He emphasized that without a reduction in the burning of fossil fuels, extreme heat events will continue to intensify. Research published Friday by scientists from Europe, the United States, and Britain concluded that human-caused climate change is unequivocally responsible for the heatwave's intensity, stating such exceptional June temperatures would have been virtually impossible 50 years ago. A comparable heatwave in June 1976 would have been 3.5 degrees Celsius cooler.

In France, three nuclear reactors were temporarily shut down due to high temperatures affecting the water needed for cooling. Tragically, deaths have been attributed to the heat, including a three-year-old boy found unresponsive in a car in a Paris suburb where temperatures exceeded 40 degrees Celsius. The circumstances surrounding how the child ended up in the car remain unclear. This incident brings the total number of children who have died in extreme weather conditions in France to three, following the deaths of two young brothers earlier in the week who were left in a hot car in Carpentras. An elderly British woman also died at a campsite in Tranche-sur-Mer.

According to the French government, at least 40 people, many of them young, have drowned while seeking relief from the heat. In Spain, the MoMo system reported that 212 deaths between Sunday and Wednesday may be linked to the heat. Italian newspaper Corriere della Sera reported five heat-related deaths, including two farmworkers and a builder.

The deputy director of the EU's Copernicus Climate Change Service, Samantha Burgess, explained that the heatwave was caused by a "heat dome" of trapped air from North Africa, preventing cooler air from moving in. Experts suggest that such extreme weather events may become the "new normal," requiring significant adaptation measures.
