As ferocious wildfires scorch large swathes of Western Europe and the United Kingdom, and a new intense heatwave builds on the horizon, Prince William, the Prince of Wales, has highlighted that these ongoing disasters are a clear wake-up call for the growing threat of climate-driven extreme weather.

Across France and Spain, the wildfire crisis has already forced more than 300,000 residents to evacuate their homes as blazes continue to spread unchecked. Spain has recorded its most destructive wildfires in the Madrid region’s modern history, while France is facing its worst fire season in 20 years.

In the UK, the scale of the crisis is already significant. A full major incident was declared over the weekend for an out-of-control wildfire burning across the Cairngorms in Scotland, while dozens of smaller blazes have ignited across the nation. In north Wales, a major wildfire burning across the Rhinogydd mountains produced plumes of smoke thick enough to be detected from satellite imagery, and two people had to be rescued after they put themselves at risk to capture drone footage of the blaze. On the Isle of Wight, a single fire, believed to have been sparked by an unattended campfire, burned an area equivalent to nearly 13 standard football pitches over five days. Over the weekend alone, London Fire Brigade responded to more than 1,300 fire-related incidents, including hundreds of grass and property fires, alongside rescue operations. The UK’s Met Office has warned that hot, parched conditions across southeast England, eastern England and London could lead to catastrophic wildfire outbreaks by Wednesday, and has issued amber heat health alerts for most of eastern England as a fourth annual heatwave approaches the region. Provisional temperature data shows July 2026 is already running 3°C above the long-term average across the UK, putting it on track to become one of the hottest Julys ever recorded.

In a public post on the social platform X, Prince William shared his solidarity with communities impacted by the blazes. “Our thoughts are with everyone affected by the devastating wildfires across France, Spain and the UK,” he wrote. “We are deeply grateful to the firefighters, emergency services and volunteers working tirelessly in extraordinarily difficult conditions. These events are a stark reminder of the challenges posed by an increasingly extreme climate and the importance of protecting both people and nature.”

Long-term climate data confirms the urgency of this warning. Europe is warming at twice the average global rate, according to the European Union’s Copernicus Climate Change Service, making it the fastest-warming continent on Earth. This rapid warming has directly fueled a sharp rise in the frequency and intensity of summer heatwaves, strained regional water supplies, and created far more dangerous conditions for devastating wildfires to ignify and spread. London Fire Brigade has issued a public appeal for people to avoid using disposable barbecues in dry open areas, properly dispose of cigarette waste, and take litter home rather than leaving it in natural areas to reduce the risk of accidental wildfire ignition.

Prince William has continued the decades-long environmental advocacy work of his father, King Charles III. In 2020, he launched the Earthshot Prize, a 10-year global initiative that awards £1 million in funding annually to five innovators developing scalable solutions to climate and environmental challenges facing the planet.

As Europe grapples with accelerating climate change that has pushed regional temperatures far above the global average, a catastrophic wave of wildfires has sparked national emergencies in two neighboring Western European nations, overwhelming emergency responders and forcing mass evacuations. The situation in France’s Gironde region, one of the worst-hit areas, has been described as “unprecedented” by top French officials, with a massive blaze that continues to defy containment efforts less than 15 kilometers from the major southwestern city of Bordeaux.

Bordeaux Mayor Thomas Cazenave announced that municipal authorities are mobilizing emergency resources to prepare for every possible outcome, including large-scale additional evacuations. “We are putting plans in place to accommodate a surge of displaced residents if new evacuation orders are issued,” Cazenave stated. For his part, French Interior Minister Laurent Nuñez emphasized that firefighters on the ground are confronting an out-of-control blaze with unpredictable behavior, noting that the active fire “has a life of its own.”

Jerome Steffe, mayor of the Gironde town of Cestas located just south of Bordeaux, called the ongoing inferno “the fire of the century.” Just two days prior, rapid expansion of the blaze forced emergency crews to evacuate all 17,000 Cestas residents overnight. So far across the Gironde region, wildfires have charred more than 42,000 hectares of land and destroyed 240 residential structures. “In my city, the situation is truly catastrophic,” Steffe told reporters. While the fire’s forward spread has slowed in recent days, Steffe warned that first responders have only claimed a small victory, with persistent risks from flying embers and sudden wind shifts that could reignite active flames. “All of our resources are focused on building protective firebreaks,” Steffe explained, “but we are all scared facing this magnitude of disaster.”

French Prime Minister Sébastien Lecornu confirmed that the country is experiencing its most extreme wildfire season on record. In a social media post on X from Monday, Lecornu reported that 116,085 hectares of land have burned across France since the start of January, with more than 13,500 separate fire outbreaks recorded. The prime minister added that nine out of every 10 wildfires in the country are linked to human activity, most starting from simple carelessness: an improperly discarded cigarette butt, an unattended outdoor barbecue, or unregulated outdoor work without fire safety precautions. Crucially, Lecornu also noted that not all blazes are accidental, confirming that some have been intentionally set. Since July 6 alone, French law enforcement has made 162 arrests related to arson in connection with the wildfires. To highlight national support for emergency crews, French President Emmanuel Macron is currently touring fire-ravaged areas of Gironde to meet with firefighters and response teams.

Wildfires are not isolated to Gironde; active blazes are also burning across multiple other French regions, including Var, Landes, and Haute-Corse on the island of Corsica. To date, more than 220,000 people have been evacuated from high-risk areas across France.

Across the border in neighboring Spain, the situation is equally dire, with the country entering its fifth day of a national state of emergency on Monday as uncontrolled wildfires burn west of the capital Madrid. Analysis of satellite imagery by BBC Verify confirms that the merged fire complex west of Madrid has already scorched more than 27,000 hectares, after separate blazes in the Almorox, Villa del Prado, and San Martín de Valdeiglesias areas combined into a single massive inferno. Images captured on July 24 and 26 show the rapid expansion of the burn scar over just 48 hours, with the blaze leaving behind a trail of destruction that has turned the village of Casavieja into what local observers describe as a “car cemetery” of burned-out vehicles. Local Spanish officials have called the outbreak the worst wildfire event in the region’s history, with more than 100,000 people evacuated across the country so far.

A forecast new intense heatwave set to arrive in the region on Tuesday is expected to worsen conditions for firefighters, with higher temperatures, lower humidity, and potential shifting winds creating new risks for further fire expansion. Climate scientists have long warned that this type of extreme wildfire event is becoming more frequent as a result of human-caused climate change. According to data from the Copernicus Climate Change Service, Europe is warming twice as fast as the global average, a trend that has amplified the frequency and intensity of summer heatwaves, strained regional water supplies, and created ideal conditions for larger, more destructive wildfires across the continent.

A devastating outbreak of wildfires burning across France and Spain has upended the lives of hundreds of thousands of people, leaving widespread destruction, disrupted travel plans, and mounting anxiety in affected communities across the Iberian Peninsula. With blazes still raging just kilometers from major urban centers and popular tourist destinations, residents and holidaymakers alike have shared harrowing firsthand accounts of the crisis, as cross-border emergency teams work around the clock to bring the fast-spreading fires under control.

In southwestern France, the fire line sits just 15 kilometers outside the major city of Bordeaux, leaving local residents gripped by fear and uncertainty. Local resident Pierre Pourquery told the BBC that a thick, acrid smoke haze has blanketed the entire city, forcing people to wear protective face masks outdoors and leaving many with severe respiratory distress. “People here are anxious and fearful,” Pourquery explained, describing the constant sense of danger hanging over the community.

The situation is even more severe in the nearby coastal resort town of Biscarrosse Plage, where a wildfire swept through populated areas earlier this week. Rachel Hanberry, a local resident whose beachfront home sits adjacent to the town’s official evacuation point, said her community has already suffered catastrophic losses. “Everyone fled here on Thursday night,” she recalled. “People had nowhere else to go, so we opened our home to as many as we could. The stress and trauma that you feel as someone living here is immense.”

Further inland, in the southeastern French town of Cotignac, resident Jo Barnes described a close call that left her family shaken after four days of mandatory evacuation. When the blaze advanced on her neighborhood, “a wall of orange flames came roaring up over the hill,” she said. By Friday afternoon, the fire had advanced to within 10 meters of her back door, just feet from a residential gas tank on her property. “It was all very dramatic.” While the surrounding hillsides were left completely charred and blackened, Cotignac itself escaped major damage, and Barnes’ home remained miraculously intact, allowing her family to return over the weekend.

The crisis is mirrored across the border in Spain, where fast-moving blazes have scorched more than 27,000 hectares alone in the central Madrid region, forcing urgent mass evacuations of entire rural villages. “Everyone had to get out of the village quickly, it was a critical situation and people were scared,” local resident Olga Congacha told AFP. She and her husband fled with little more than the handful of essential items they could grab on the way out: critical personal documents and a few changes of clothes.

In Spain’s eastern Castellón province, where blazes have burned across vast swathes of forest and rural land, long-term residents say they have never seen a wildfire of this scale and intensity. “I’ve seen major fires, but only on television. Nothing like this, here and now,” said local resident Ricardo Pozo. Maria Garcia, a resident of the Castellón town of Betxí, added that the fire has brought daily life to a complete standstill for evacuees. “You can’t go out to work, you can’t go about your daily life. You can see the mountains you’ve known your whole life burning,” she said.

Beyond local residents, the wildfires have also completely upended travel plans for thousands of summer holidaymakers who flocked to the region’s popular coastal destinations. British visitor James Hillier was visiting his son in Lacanau, a seaside community 42 kilometers east of Bordeaux in France’s Gironde department, when the smoke moved in. “The whole town got consumed by smoke,” he told the BBC. “There was ash falling from the sky and I noticed a big lump of it landed on my hand.” He and his wife fled to Bordeaux for safety, only to find the city’s air so heavily polluted that “the air was acrid – it stung your eyes and people were wearing masks.” The pair ultimately cut their trip short and traveled further north to escape the hazard.

Another British visitor, Sarah from Hertfordshire, also cut her family’s week-long Bordeaux vacation after smoke seeped into their rented apartment even after they sealed all windows and doors. She warned her sister-in-law Georgia, who was scheduled to join the group in Lacanau, to cancel her trip, and Georgia rebooked accommodation in the Loire Valley instead. But Georgia says she has been unable to secure a refund for her canceled Lacanau booking, since the fire had not reached the town when she canceled. “If we don’t find a solution with them we currently stand to lose over £3,500,” she said.

Across both countries, the blazes have scorched tens of thousands of hectares of land and forced more than 300,000 people to evacuate their homes and vacation properties, with emergency crews from both nations continuing their containment efforts as the fire season enters its most dangerous period.

A catastrophic wave of unprecedented wildfires is sweeping across large swathes of France and Spain, triggering mass evacuation orders for more than 300,000 residents as climate-fueled heatwaves create extreme, fire-friendly conditions across Southern Europe.

In France, the country is facing its most destructive wildfire season in 22 years, with the southwestern Gironde region surrounding Bordeaux bearing the brunt of the destruction. More than 200,000 local residents have already been forced to flee their homes, as flames have consumed more than 420 square kilometers of land—an area four times the size of the French capital—in less than four days. The fire line currently sits just 15 kilometers from the southern edge of Bordeaux, advancing rapidly through the country’s iconic wine-growing region, destroying forests, agricultural land and threatening critical infrastructure along the way.

The blazes have even put sensitive military and industrial sites at risk, including facilities involved in ballistic missile development, rocket motor production and hazardous chemical processing. Satellite imagery captured over Gironde reveals a vast, scorched black landscape, with plumes of thick smoke drifting hundreds of kilometers inland. Most alarmingly, the extreme intensity of the fires has spawned a rare fire-generated thunderstorm, a meteorological phenomenon that occurs when intense wildfire heat pulls smoke, ash and water vapor rapidly into the upper atmosphere. As the heated air cools, it forms cumulonimbus thunderclouds capable of producing lightning that can ignite new blazes, alongside unpredictable hail and rain outbreaks. These erratic conditions have made containing the fires far more challenging for emergency crews.

To the west, in the mountainous region surrounding the Spanish capital Madrid, three separate large wildfires have burned roughly 770 square kilometers of land, with regional officials labeling the event the worst wildfire disaster in the region’s recorded history.

Thousands of emergency responders have been deployed across both countries to combat the spreading blazes. In Gironde alone, the response effort includes 2,500 firefighters, 1,500 military personnel and 1,200 police officers and gendarmes. Aerial firefighting assets, including Canadair water-bomber aircraft capable of scooping 6,000 liters of water from nearby lakes or the Atlantic Ocean in just 12 seconds, have conducted continuous shuttle missions to drop water and fire retardant along fire perimeters. Near the coastal town of Lacanau, heavy construction equipment has been used to carve 100-meter-wide firebreaks, stripping all vegetation from strips of land to starve advancing flames of fuel. Spanish emergency teams have deployed similar tactics to contain their blazes.

This year’s extreme wildfire season comes on the heels of a record-breaking sweltering summer across Europe, where widespread heatwaves have pushed temperatures above 40°C (104°F) across much of the continent. Climate scientists and on-the-ground officials warn that rising global temperatures driven by climate change have created the hotter, drier conditions that allow wildfires to spread faster and burn with far greater intensity. With forecasts calling for sustained high pressure that will bring continued dry, rising temperatures across the region over the coming week, officials and residents in both countries are bracing for worsening conditions as emergency crews work around the clock to contain the unprecedented disaster.

In a groundbreaking and alarming development that underscores the growing risk of extreme wildfire behavior linked to climate change, French officials have confirmed that an out-of-control wildfire in southwest France grew powerful enough to spawn its own thunderstorm — a rare weather event never before recorded in the nation’s history.

The massive blaze, which ignited near the commune of Saumos in the Gironde region on July 22, has already carved a devastating path across the region. As of official updates, it has consumed more than 420 square kilometers of protected forest and dry scrubland, ruined or completely destroyed over 240 residential structures, and forced an unprecedented 220,000 local residents to flee their homes to escape the advancing flames.

Two days after the fire first broke out, at approximately 6:20 p.m. local time on Friday, Gironde’s departmental fire and rescue service confirmed the formation of a pyrocumulonimbus, or pyroCb — an enormous, storm-forming cloud generated entirely by the extreme heat of an intense wildfire. The cloud weakened temporarily overnight as atmospheric humidity climbed, but reformed repeatedly in subsequent days as the inferno continued to rage.

Unlike ordinary thunderstorms that form from atmospheric heat exchange, a pyrocumulonimbus is born directly from the extreme heat of a large wildfire. Theodore M. Giannaros, a fire meteorologist at the National Observatory of Athens, explains the phenomenon simply: it is what happens when a wildfire grows so large and hot that the smoke and hot air rising from its flames condense into a full-fledged storm cloud.

The conditions required to spawn a pyroCb are very specific. There is no set threshold temperature for formation, but the atmosphere must match the structure that breeds dry thunderstorms: extremely hot, parched air close to the ground, capped by a layer of cooler, more moisture-rich air higher in the atmosphere. As superheated air loaded with smoke, ash and water vapor surges upward from the wildfire, it cools as it climbs, and water vapor condenses around tiny ash particles. Above the freezing altitude, these condensing droplets turn to ice crystals, whose collisions separate electrical charges just as they do in a regular thunderstorm.

The result is an electrified black storm cloud that generates lightning, erratic winds and unpredictable fire behavior. Unlike a normal storm that forms independent of a fire, this storm system amplifies the disaster that created it. Rising air pulls powerful gusts of wind straight toward the heart of the blaze, while cold downdrafts hurl strong gusts back to the surface across the surrounding landscape. These sudden wind shifts can redirect the fire’s path, split it into multiple separate fire fronts, or send flames racing into untouched areas that were previously considered safe.

Giannaros notes that this is a self-reinforcing feedback loop, not a one-sided side effect of the fire. “Once it forms, the cloud becomes its own weather system, sitting on top of the fire and making it harder to predict,” he explained. In the most extreme cases, these systems can even spawn rotating fire columns called fire whirls — essentially fire-fueled devils that move across the landscape spreading destruction. True fire tornadoes are far rarer, but one such event hit Redding, California during the 2018 Carr Fire, packing EF-3 equivalent winds and killing a fire inspector.

For frontline firefighting crews, the formation of a pyroCb creates unprecedented danger. Escape routes can be cut off without warning when lightning sparks new wildfires far beyond the reach of deployed crews and equipment. Direct attacks on the main blaze become impossible, forcing teams to abandon containment efforts and retreat to defend populated communities at risk. The biggest threat, Giannaros emphasized, is that the fire can spread faster than emergency managers can organize evacuation orders for at-risk populations.

Until this event, pyrocumulonimbus events were almost exclusively documented in North America and Australia, where they only form over the most extreme large-scale wildfires. Canada alone recorded a staggering record 142 pyroCb events in 2023. In Europe, the phenomenon has been extremely rare: only one confirmed event was recorded in Portugal during the catastrophic 2017 wildfire season. France’s 2022 Gironde fire marks the first confirmed pyroCb in the nation’s recorded history, according to the French National Firefighters Federation.

The emergence of this rare extreme fire event in France aligns with broader climate trends across the European continent. Data from the EU’s Copernicus Climate Change Service and the World Meteorological Organization shows that Europe has been warming faster than any other continent on Earth — at roughly twice the global average rate since the 1980s. As a result, heat waves have grown far more frequent and severe, widespread drought has parched much of southern Europe, and dense forests have dried out into ideal wildfire fuel.

Giannaros explained that hotter, drier conditions create far more opportunities for the extreme wildfires that can spawn pyroCbs, but the scientific community still lacks sufficient long-term data to confirm a clear upward trend in these events across Europe. The European research project ROSETTA is currently working to close this knowledge gap, to help emergency managers better prepare for and respond to these extreme events in the future.

Giannaros added that one of the most common public misunderstandings about pyrocumulonimbus is that the storm cloud is just an inconsequential side effect of a large fire. In reality, for as long as the storm sits above the flames, it actively shapes the fire’s future path and intensity, turning a predictable blaze into an unpredictable, deadly disaster.

PARIS — Unrelenting heat waves and months of deficient rainfall across Western Europe have sparked catastrophic, historic wildfires that have driven hundreds of thousands of people from their homes, marking one of the largest mass evacuation efforts on the continent since World War II. Forecasts of even higher temperatures later this week threaten to hinder containment efforts, as blazes have already scorched an area four times the size of Paris across southwestern France and continue to burn dangerously close to Spain’s capital, Madrid.

Decades of climate data confirm that Europe is warming faster than most other regions on the planet, and 2025 has already seen multiple extreme heat events that have primed the landscape for uncontrollable wildfire. While Spanish firefighters have described the current blazes as too intense for direct frontal attacks, officials in France reported a small but hopeful development on Monday: the rapid spread of the massive Gironde region fire appears to be slowing for the first time.

A core driver of this disaster is the rising heat and dryness amplified by human-caused climate change. Prolonged above-average temperatures starting with a record-breaking June heat wave created widespread drought conditions across the region. Extreme heat saps moisture from vegetation, turning even normally damp brush and trees into perfectly flammable fuel that allows flames to spread much faster and burn with far greater intensity than historic wildfires. This summer’s extreme heat was effectively impossible without the influence of climate change, according to a June analysis from the international research collective World Weather Attribution.

French national meteorological service Météo-France confirmed that June 2025 was the hottest ever recorded in the country, with average temperatures 3.8 degrees Celsius (6.8 degrees Fahrenheit) higher than long-term norms, while total rainfall dropped to nearly half the average for the month. Spain, which already faces regular summer wildfire season, has seen conditions grow far more dangerous as climate change pushes summer temperatures higher and extends dry periods. Compounding this risk is the decades-long decline of traditional farming and forest industries that once cleared overgrown vegetation, leaving large swathes of unmanaged wilderness primed to ignite like a tinderbox.

This year’s wildfire season has already shattered all previous European records. Data from the European Union’s European Forest Fire Information System shows more than 300,000 hectares (3,000 square kilometers, or 1,160 square miles) have burned across France and Spain alone to date. France’s Interior Ministry reports that 115,000 hectares (1,150 square kilometers, 444 square miles) have burned in the country since January – the highest annual total recorded in France’s modern history, surpassing all previous full-year wildfire damage.

In Spain, the total burned area so far this year has reached 153,000 hectares (1,530 square kilometers, 591 square miles), six times the total area burned in the first half of 2024, according to Ecological Transition Minister Sara Aagesen. Just over a week ago, the country saw its second largest and third largest wildfires on record burn simultaneously. One blaze in rural Avila, located west of Madrid, alone consumed more than 50,000 hectares of land. Earlier this month, 13 people died in a wildfire in southeastern Almeria, marking Spain’s deadliest wildfire event in recent memory.

To date, more than 300,000 people have been displaced from their homes across the two countries, an event the European Union described Monday as one of the largest evacuation operations in modern European history. In France alone, more than 250,000 people have been evacuated, 220,000 of them from the southwestern Gironde region. As France prepares to enter its peak August tourist season, Gironde officials have implemented strict emergency measures, closing popular holiday destinations and banning holiday camps for children and people with disabilities to avoid putting more lives at risk. In Spain, the government confirmed 76,000 people have been evacuated, while an additional 30,000 remain confined to their homes as fires advance near their communities.

European countries have rallied to support the affected nations through cross-border emergency aid. European Commissioner for crisis management Hadja Lahbib announced Monday that the EU has coordinated the deployment of seven firefighting aircraft and four helicopters from Czechia, Croatia, Germany, Portugal, Slovakia, Sweden and Turkey to France, while an additional six planes from Greece, Italy and Turkey have been sent to Spain. “No country should ever have to face a disaster of this scale alone,” Lahbib said in a statement. “To the people of France and Spain: Europe will stand with you until the fires are out.” The EU’s Copernicus satellite program is also providing emergency responders with real-time, updated maps of fire risk to support containment efforts.
