The scorching heatwave sweeping across Europe bears the unmistakable signs of climate change and is described by UN climate chief Simon Stiell as “the latest consequence of fossil fuel pollution frying our planet.”
This week, Europe faced record-breaking temperatures in France, Britain, and Spain, prompting authorities to issue high-level heat alerts across multiple countries.
“Europe’s brutal heatwave is clearly a direct result of the climate crisis — it’s the latest toll for burning massive amounts of coal, oil, and gas that are cooking our world,” Stiell stated.
He emphasized, “As long as humanity continues to burn enormous quantities of fossil fuels, extreme heat events will only intensify.”
Scientists agree that recurring heatwaves are a clear indication of global warming and warn that such events are expected to become more frequent, prolonged, and severe.
In Western Europe, the heatwave has led to dozens of deaths, caused power disruptions, and resulted in the closure of schools and cultural sites, with forecasts indicating that these extreme temperatures could last until the end of the week.
Britain shattered its previous temperature records for June, recording 96.98°F (36.1°C) in southern England — a new high for the month — as a high-pressure dome settled over much of Western Europe.
Paris temperatures hit a record 105.2°F (40.9°C), a day after France experienced its hottest day in nearly 80 years, with peaks reaching 112.2°F (44.3°C) in Pissos, in the southwest.
Italy’s health authorities placed 16 cities— including Florence, Milan, Rome, Turin, and Verona— under the highest heat warning, warning that the heat could intensify between Sunday and Monday.
Since the heatwave began, at least 48 fatalities in France have been linked to drowning incidents as people sought relief from the extreme heat, with two young children losing their lives in a car accident caused by heat.
In Spain, two elderly individuals died from heatstroke after several days of temperatures above 104°F (40°C), although conditions started to ease on Wednesday following an intensely hot stretch, according to the national weather agency, AEMET.
Agricultural groups reported that hundreds of thousands of poultry birds in Brittany and the Pays de la Loire died due to the extreme temperatures.
France’s nuclear power plants, which provide the majority of the country’s electricity, reduced output by approximately 7% because high temperatures limited the availability of cooling water.
The weather pattern responsible for this extreme heat is known as an Omega block, which causes temperatures to rise as much as 18°C (around 32°F) above normal, according to the Reuters Climate Monitor.
This phenomenon resembles the Greek letter Omega, with a large bulge trapping warm air over certain regions for extended periods, while cooler air resides on its edges. Climate change is exacerbating the intensity of these heatwaves and storms.
In Britain, the record-breaking heat prompted only the second-ever extreme heat warning, causing hundreds of schools to delay or shorten their days as officials warned that even healthy individuals could be at risk. The temperature reached 96.98°F (36.1°C) in Gosport, Hampshire, surpassing the previous June record of 96.1°F (35.6°C) set in 1957 and matched in 1976.
