Europe’s Heatwaves Expose a Continent Built for a Cooler Past

Europe is facing another severe heatwave that has disrupted transport, strained public services and raised health concerns, especially for older people. While temperatures in the 30s or low 40s may seem familiar to many people from the Middle East or North Africa, the impact in Europe is different because many homes, schools, hospitals and transport systems were not designed for this level of heat. Reuters reported that the latest heatwave brought temperatures above 40°C in parts of Europe, with France warning that the death toll was expected to rise.

The first problem is that much of Europe was built for cold winters, not extreme summers. Older buildings often retain heat, many apartments lack cooling, and dense city streets can trap warmth overnight. Copernicus says Europe is the fastest-warming continent, and that 2024 was the warmest year on record for the region, with heat stress days continuing to increase.

The second issue is limited access to air conditioning. According to the International Energy Agency, air-conditioning ownership in Europe remains relatively low, at about 20%. That means many families, seniors and lower-income residents cannot easily cool their homes during long heatwaves, especially when indoor temperatures stay high overnight.

The third risk is health. Extreme heat is not only uncomfortable; it can be deadly. The World Health Organization says an estimated 61,672 heat-related excess deaths occurred in Europe during the summer of 2022, and that high-intensity heatwaves can cause sharp increases in mortality.

The fourth pressure point is infrastructure. Heat can affect rail lines, electricity demand, hospitals, agriculture and water systems. Reuters reported that recent European heat has put pressure on public infrastructure, broken temperature records in several countries and caused disruption as the heat moved east across the continent.

This is why European heat warnings should not be treated as exaggeration. The issue is not only the number shown on the thermometer, but whether homes, cities, transport systems and health services are prepared for it. As climate change makes heatwaves more frequent and severe, Europe’s summer is becoming a public-health and infrastructure challenge, not just a seasonal inconvenience.
