Europe is facing one of its most severe early summer heatwaves, with record-breaking temperatures pushing infrastructure to its limits. As temperatures climb above 40°C in several countries, roads are melting, tram tracks are buckling, train services are being disrupted, and power grids are coming under increasing pressure. Hospitals are also reporting a surge in heat-related cases as millions endure dangerous conditions. The World Health Organization has warned that Europe is the fastest-warming continent on Earth and has linked the ongoing heatwave to a growing number of excess deaths.
