Europe is heating twice as fast as the global average
Across Europe, a summer that was already lethal is preparing to strike again. France recorded more than 2,000 excess deaths during a single week of record June heat, with Belgium and the Netherlands adding thousands more to a toll concentrated almost entirely among the elderly and the vulnerable. Europe warms at twice the global average rate, meaning these events are not aberrations but accelerating features of the continent's future — and forecasters warn that a fresh wave of extreme heat is already building toward this weekend.
- France's deadliest week of the summer killed 2,025 people above normal mortality levels — a 29% spike — with Paris alone seeing deaths climb 62% as temperatures hit a national record near 41°C on June 24.
- Belgium called its 1,222 excess deaths 'unprecedented,' the Netherlands recorded 480 more, and 72 people drowned across France as desperate residents sought relief in rivers and lakes.
- Nearly 7,000 fires have ignited across France since summer began, and a wildfire near Sainte-Marie-la-Mer forced almost 3,000 people to flee their homes in a single night.
- A high-pressure system building from the Azores is now pushing a fresh wave of 40°C heat toward southern France and Britain this weekend, with Portugal declaring a state of alert and Spain placing southwestern regions on orange warning.
- Health authorities admit the current death toll is almost certainly an undercount, with full mortality data still being compiled even as the next heatwave arrives.
Europe has not yet finished counting its dead from one record heatwave when another is already forming on the horizon. France recorded more than 2,000 excess deaths in the final week of June alone — a 29 percent spike above normal — with the Paris region seeing mortality climb 62 percent. On June 24, France logged its hottest day ever, with temperatures approaching 41 degrees Celsius and half the country placed under red alert. Health officials have acknowledged the true toll is likely higher than current figures suggest.
The suffering extended well beyond France's borders. Belgium documented 1,222 excess deaths — a 39 percent rise, with nearly half among people aged 85 and older — prompting its health ministry to describe the figures as unprecedented. The Netherlands recorded roughly 480 excess deaths, again concentrated among the elderly. Across France, 72 people drowned since mid-June as residents sought escape from the heat in rivers and lakes.
Underneath these numbers lies a structural reality: Europe is warming at roughly twice the global average rate, making it the fastest-heating region on Earth. That acceleration is not a temporary condition but a permanent shift, intensifying each summer's heatwaves, straining water supplies, and fueling wildfires. France has seen nearly 7,000 fires since summer began, and a blaze near Sainte-Marie-la-Mer forced the evacuation of almost 3,000 people in late June.
Now forecasters warn of a fresh surge arriving this weekend. A high-pressure system from the Azores is expected to push temperatures back toward 40 degrees Celsius across southern France, with red alerts already issued for Friday and Saturday. Portugal has declared a state of alert through Tuesday; Spain has placed its southwestern regions on orange warning. The continent, still grieving and still counting, must now prepare to absorb another blow.
Europe is bracing for another surge of extreme heat this weekend, even as the continent is still reckoning with the deadly toll of a record-breaking heatwave that swept through in late June. France alone recorded more than 2,000 excess deaths during the final week of that heat event—a 29 percent spike compared to the week before—with health officials warning that the true number is likely higher. The surge in mortality was concentrated among people over 45, and in the Paris region alone, deaths climbed 62 percent. On June 24, France experienced its hottest day on record, with temperatures near 41 degrees Celsius in the capital and half the country placed under red heat alert.
The human cost across Europe has been staggering. Belgium documented 1,222 excess deaths during the same period, representing a 39 percent increase above normal levels, with nearly half of those deaths among people aged 85 and older. The Dutch recorded approximately 480 excess deaths, again predominantly among the elderly population. Beyond the heat itself, drowning deaths surged across France, with 72 people killed in the water since mid-June as residents sought relief from the oppressive temperatures. The scale prompted Belgium's health ministry to describe the mortality figures as "unprecedented."
What makes this moment particularly alarming is the trajectory of warming across the continent. Europe is heating at roughly twice the global average rate, according to the Copernicus climate service, making it the fastest-warming region on Earth. This accelerating warmth is not a one-time event but a structural shift—intensifying summer heatwaves, straining water supplies, and triggering increasingly severe wildfires. France has already seen nearly 7,000 fires ignite since the start of summer, consuming roughly 8,700 hectares. In late June, a wildfire near the town of Sainte-Marie-la-Mer spread rapidly to neighboring Canet-en-Roussillon, forcing the evacuation of nearly 3,000 people.
Forecasters are now warning of a fresh wave of extreme temperatures arriving this weekend. A high-pressure system building from the Azores is expected to push heat northward across France and into southern Britain by Saturday. Temperatures are predicted to reach 40 degrees Celsius in southern France, with peaks of 36 to 37 degrees expected around Bordeaux, Toulouse, and Agen. Météo-France has issued red alerts for Friday and Saturday, flagging forest fire risk as "very high" compared to typical summer conditions. The Iberian Peninsula faces similar threats, with Portugal's government declaring a state of alert through Tuesday and Spain placing southwestern regions on orange alert as temperatures approach 40 degrees.
The timing is particularly grim because the continent has not yet recovered from the previous heatwave. French health authorities acknowledged that their initial death count of 2,025 is likely an underestimate, with actual mortality expected to be substantially higher once full data is compiled. The elderly, those without air conditioning, and people living in urban heat islands remain most vulnerable. Meanwhile, millions of Americans are already enduring prolonged extreme heat and humidity across central and eastern states during the July Fourth holiday weekend, suggesting this is not merely a European phenomenon but part of a global pattern of intensifying temperature extremes. The question now is not whether the heat will arrive this weekend, but how many more deaths and evacuations it will bring.

The figure was likely an underestimate and mortality would therefore be higher than these initial figures— French health ministry
The number of deaths during a heatwave was unprecedented— Belgium's health ministry
La Conversación del Hearth Otra perspectiva de la historia
Why does the death toll spike so dramatically during these events? It's not just about the temperature itself, is it?
No. It's about vulnerability meeting extremity. The elderly, people on certain medications, those in poorly ventilated housing—they can't regulate their body temperature the way younger, healthier people can. When you're 85 and it's 41 degrees outside and your apartment has no air conditioning, your organs start to fail. The heat doesn't kill you quickly. It exhausts you.
France says 2,025 deaths, but also says that's an underestimate. How much higher could it actually be?
They won't know for weeks or months. Excess deaths are calculated by comparing what actually happened to what normally happens during that week. But some deaths are indirect—someone has a heart attack because their body is under extreme stress, or they fall because they're confused from heat exhaustion. Those take time to attribute.
Belgium's figure is striking—1,222 deaths, nearly 40 percent above normal. Is that worse than France's situation?
It's proportionally devastating for a smaller country. But France's numbers are actually more severe in absolute terms. The difference is Belgium's health system was perhaps more prepared to count and report. France is already saying their count is incomplete.
You mentioned drowning deaths. That's an unusual consequence of a heatwave.
People flee the heat to water—rivers, lakes, beaches. But they're often elderly, sometimes confused from heat stress, sometimes they underestimate the current or their own weakness. Seventy-two drowning deaths in France in two weeks is extraordinary.
What does it mean that Europe is heating twice as fast as the global average?
It means this isn't a temporary aberration. It's the new normal accelerating. Every summer will likely be hotter than the last. The infrastructure, the medical systems, the water supplies—they were built for a cooler Europe. They're not keeping pace.
And now another heatwave is coming this weekend?
Yes. The continent hasn't recovered. Hospitals are still processing the previous surge. Water tables are depleted. Forests are drier. And the heat is coming again.
