Western Europe hit by 40°C heat dome

What happened

A powerful heat dome trapped hot air over western Europe, bringing extreme temperatures across the region. France restricted public alcohol consumption during nationwide Music Day celebrations, Spain cancelled World Cup watch parties, and Germany and Italy issued urgent weather alerts.

Why it matters

Scientists warn that such extreme temperatures early in the summer could indicate a prolonged season of dangerous heat ahead. Climate change is increasing both the frequency and intensity of heatwaves, creating risks of wildfires, train disruptions, and public health emergencies.

What to watch

Officials across the continent are warning of health risks and infrastructure strain. Temperatures were expected to top 40° Celsius across parts of France and Spain as the heat dome continues.
