A severe heatwave scorched Europe on Saturday, stretching from Scandinavia to the Alps and causing at least 12 deaths. Temperatures exceeded 40 degrees Celsius in several regions, breaking long-standing records in Germany, Denmark, the Czech Republic, and Switzerland. Authorities issued extreme heat warnings across Germany and neighboring countries as the heat moved eastward. France, Italy, and the United Kingdom also recorded unprecedented highs earlier in the week.

Scientists said such an intense heatwave would have been nearly impossible without human-induced climate change, which has made extreme nighttime temperatures far more likely. Governments across Europe took emergency measures: France restricted alcohol sales and postponed outdoor events, while Italy declared red alerts in 18 cities. Nuclear power plants in Hungary and Switzerland reduced or halted operations due to overheated river water. Rail operators in Germany and other countries reduced services and allowed free cancellations to prevent infrastructure damage.

Meteorologists forecast that the extreme heat will ease later in the week, with thunderstorms expected by Sunday. The phenomenon, known as an “omega block,” has trapped hot air over Europe, pushing seasonal averages far above normal and straining public health and essential services.
