A heated debate: Europe’s infrastructure, while beautiful, is causing heat-related deaths

Europe’s unprecedented early summer heatwave has been linked to more than 1,300 excess deaths across the continent since June 21, according to the World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus, per the BBC. The WHO confirmed that the deadly conditions, driven by a massive heat dome over Western Europe, have shattered temperature records in over 15 countries, including France, Germany, Spain, and the UK.

Infrastructure built for cold, not heat

Europe’s vulnerability stems from infrastructure designed for cold climates, not extreme heat, The Times of India reported. According to Fortune, only 20% of European homes have air conditioning, compared to 90% in the U.S., per the International Energy Agency. In the UK, AC ownership drops to just 7%.

Many older homes, with tin roofs and thick walls that trap heat, become “furnaces” during high temperatures, making recovery impossible even at night, per a report from Bhaskar English. In the same report, Associate Professor of Architecture at Cornell University Timur Dogan was cited, saying, “When nights also remain hot, houses become hotter day by day. The condition inside the house worsens further. The body never recovers properly.” 

The heat is apparently so bad that train tracks in Germany are even melting, Bhaskar English reported, showing photos of several melted tracks.

Climate change as the dominant driver

While a developing El Niño is amplifying heat, scientists say human-caused climate change is the primary force, pushing global temperatures 1.4°C above pre-industrial levels for four consecutive years, Fortune reported. Europe is now the world’s fastest-warming continent, heating at twice the global average, the report confirmed. 

In 2025 alone, heatwaves killed 24,400 people across Europe, 16,500 of whom Fortune said are directly tied to climate change. According to Fortune, at least 40 people have drowned in France since the heatwave began, seeking relief in rivers and lakes. Two toddlers died in a hot car in France, and three elderly residents died near Bordeaux, the report confirmed. The French government has now allocated 100 million euros to install AC in hospitals, Bhaskar English confirmed.

The WHO urges governments to redesign cities with more trees, shade, and cooling centers, and to protect workers from heat stress.
