Europe is experiencing an intensified cycle of extreme heatwaves driven by a “heat dome” trapping air over the continent, with climate change making these events up to 4°C hotter, according to analysis from Climameter. As temperatures reach record highs, the EU’s Copernicus Climate Change Service reports that Europe is warming twice as fast as the global average, leading to widespread infrastructure strain, school closures, and increased public health risks.
Why are heatwaves becoming more frequent in Europe?
Meteorological data indicates that heatwaves are no longer isolated anomalies but are becoming more frequent, longer, and occurring outside of traditional summer months. Meteorologist Rubén del Campo of the Spanish weather service Aemet notes that of the twelve heatwaves recorded in Spain since 1975, half have occurred since 2015. This trend aligns with projections from the UN climate agency, which warns that the next five years are likely to see further shattered temperature records.

Europe is currently the fastest-warming continent on Earth. Since the 1980s, average temperatures across the continent have risen at double the rate of the global average, according to the Copernicus Climate Change Service.
How does the “heat dome” impact infrastructure?
Extreme heat is testing the limits of European infrastructure, from power grids to public transport. In Italy, the heat has caused blackouts in Milan and Turin due to a surge in air-conditioning demand, while Rome’s public bus operator, ATAC, reported that electric vehicles are returning to depots early for charging as cooling systems drain batteries faster than anticipated. In France, the national thermal indicator reached 29.8°C, surpassing the previous records set during the devastating heatwaves of 2003 and 2019, according to Météo-France.
What are the health risks associated with current heat levels?
Public health officials have issued urgent warnings as the heat spreads across the continent. In France, Prime Minister Sébastien Lecornu reported 40 drowning fatalities in a single week as residents sought relief in rivers and bodies of water. Health facilities are also feeling the strain; hospitals in Parma, Italy, have recorded a sharp increase in emergency room visits. Authorities in Italy have advised the public to remain indoors during peak afternoon hours and to modify dietary habits to include lighter, hydrating meals.
Pro Tip: Staying Safe During Extreme Heat
Experts recommend keeping windows closed and blinds drawn during the day to prevent heat gain. If you must be outside, prioritize lightweight clothing, drink water consistently, and avoid strenuous physical activity during the hottest part of the day, typically between 12:00 PM and 4:00 PM.

How do current heat trends compare to climate projections?
Recent observations suggest that the intensity of heat events is outpacing previous climate models. Studies cited by the EU indicate that the Mediterranean region could face double the number of heat events previously anticipated. The Climameter analysis provides a clear breakdown of human-caused influence on current temperatures: Milan is currently 3.8°C warmer, Zaragoza is 4°C warmer, and Paris is 2.4°C warmer than they would be without climate change factors.
Frequently Asked Questions
- Why are schools closing in the UK? Hundreds of schools have shut down due to concerns that buildings are not equipped to keep students safe in temperatures approaching 39°C.
- Is the heatwave ending? While Spain is beginning to see temperatures abate, Météo-France warns that heat waves could return to parts of Europe and persist through mid-July.
- What is a heat dome? It is a high-pressure weather pattern that acts like a lid on a pot, trapping hot air over a specific region and preventing it from dissipating.
