'We were not ready for this'

By Laura Millan and Joe Wertz

Patricia Lamela was driving back to the Galician town of Larouco in northwest Spain when she got the call. It was Aug. 13, just before 7 p.m., and a neighbor told her there was a fire in the forest.

Lamela, the mayor of Larouco, wasn’t surprised by the news. The area around her small village of less than 500 residents had been baking at temperatures above 40C (104F) for over two weeks amid one of the longest and hottest heat waves on record in Spain. Weeds and bushes that had thrived during a particularly wet spring dried up and became fuel to the fire. The absence of people cleaning and maintaining the forest in one of Spain’s least populated regions meant a large blaze was only a matter of time.

With her hand still on the steering wheel, Lamela notified regional authorities and asked for help. Then, she called the clerk to get the town’s only fire truck ready and asked a nephew to post a message on the village’s WhatsApp group calling for volunteers. 

“For the first few hours, it was just us neighbors and our truck,” she said. “The regional government and their resources were fighting fires elsewhere.”

Within hours the Larouco fire became the biggest on record in Galicia, burning through more than 300 square kilometers (116 square miles). The town was not alone in its misery, as dozens of similar blazes were erupting across Spain and Portugal over mid-August, overwhelming authorities and leaving officials struggling to coordinate extinguishing efforts across dozens of agencies and departments, according to multiple accounts by local politicians, firefighters and neighbors who all fought the flames themselves.

Beyond the Iberian Peninsula, it’s been a similar tale of destruction in Europe. This year more than 1,900 wildfires have sparked across the European Union, scorching a record 9,860 square kilometers  — an area larger than Cyprus, according to satellite estimates from the EU’s European Forest Fire Information System.

Climate change is playing a major role in the endless scenes of smoke and fire. Europe is the world’s fastest-warming continent, and the searing heat and drought that fueled this summer’s blazes will intensify in the coming decades, setting the stage once again for strong winds to fan flames and spread fires. Yet global warming is only part of the story: a lack of coordination between agencies, fragmented land ownership and under-resourced fire services also turned many outbreaks into uncontrollable blazes. While some countries like Greece have begun to demonstrate how major investment in monitoring and firefighting equipment can soften the worst outcomes, Europe still faces risks ahead as the world continues to break new temperature records. 

For Galicia, one of Europe’s most fire-prone regions, this summer overturned long-held assumptions about how blazes behave. As Lamela explained, fires had always raced uphill in her town, not down. Volunteers believed that if they protected the village at the bottom of the valley, they would be safe. The flames were expected to burn through the forest and stop at the ridge, buying time for regional crews to arrive and put them out.

On Aug. 13 that didn’t happen. The flames continued to climb the incline before wild winds caused the fire’s path to move unpredictably. 

“That fire had a weird behavior the whole time,” Lamela said. “First it went up, and then it crossed the ridge and went down at incredible speed toward [the village of] Freixido.”

In Larouco volunteers worked days without rest. One firefighter collapsed after 17 hours straight on the job. The support crews they received from the local, regional and central governments, and the army was intermittent and never enough, as similar fires broke out simultaneously in neighboring towns. For the first time ever for forest fires, Spain activated the European Union’s Civil Protection Mechanism, which allows EU members to request help from other countries in the bloc.

“We were not ready for this,” Lamela said. “There was a lack of coordination, but what coordination could there be when it was so violent, so big and fast and happening everywhere at the same time? We would have needed three command posts and four times as many resources as we had.”

Still, swift action was not helped by political bickering. Even after the immediate emergency was over, a fire at a municipal dump containing plastic waste in the neighboring town of A Rúa burned for over two weeks amid a dispute between rival county and regional political parties over who should extinguish it, said María González, the mayor of A Rúa. “Meanwhile, no one was doing anything,” she said.

Across the Spanish border, there were other bureaucratic bottlenecks preventing Portugal from tackling its wildfires with speed this summer. Last month Conservative Prime Minister Luís Montenegro was criticized for not moving quickly enough to request firefighting help from the EU and failing to declare a “state of calamity” that would have unlocked more resources to affected areas. Government decisions often need to be approved at weekly cabinet meetings, which in August are less frequent due to summer holidays.

Beyond politics, one of the thorniest issues for preventing wildfires in Europe has been the region’s patchwork of private land ownership.

Most forest area in northern Spain and Portugal is privately held and divided into thousands of small plots of land, many held by absentee owners who neither maintain nor even know they own the property. Legally, they must clear brush. As an old Galician saying goes, fires are not extinguished in summer, but in winter by keeping the forest clean. Yet enforcement is almost impossible.

The consequences are stark. Take what happened in A Rúa. Fires burnt much of the town’s privately-owned patches of forest and abandoned agriculture fields — leaving a grim, charred landscape. But satellite images showed the disaster didn’t spread to the village and its immediate surroundings, where for decades locals have grown Godello vineyards, a variety that produces a white wine known for its citric taste, similar to Chardonnay. 

“The vineyards saved us,” said González, the mayor. “If the rest of our land was managed that way, maybe some would have burnt, but not 30,000 or 40,000 hectares.”

Similar dynamics played out in the department of Aude in southern France this summer. The region suffered its worst fires in more than 70 years, with an area bigger than Paris burned. 

The most significant damage was on land where vineyards no longer existed and had been abandoned prior to the fires. “Everywhere there were vineyards, for the most part, the fire was stopped,” French Prime Minister François Bayrou told journalists during a tour of the burnt area in August. “Where there were no longer vineyards, where thickets, scrubland, and garrigue had taken their place, we saw the catastrophe worsen, with the fire spreading faster.”

Even with best practices and billions of euros of funding, climate change is making wildfires harder for governments to snuff out in Europe.

In Greece, Turkey and Cyprus, all of which experienced large blazes this summer, such extreme conditions would have happened once in a century in a world without climate change. Today, they’re expected to happen once every two decades, according to World Weather Attribution scientists at the Imperial College in London.

With a view to preventing future disasters, Greece is implementing a 2 billion-euro ($2.3 billion) program using financing from the EU’s Recovery and Resilience Facility to buy amphibious firefighting aircrafts, drones for aerial monitoring, detection and extinguishing systems, control centers and over 1,000 firefighting vehicles. The country has also beefed up efforts to prevent blazes, including cleaning forests.

These measures have helped Greece avoid the uncontrolled and simultaneous massive fires that have ravaged Spain, France and Portugal this summer. Still, it was not without disruption: around 32,000 people were evacuated this season, including 5,000 tourists on the island of Crete. At least one person died, 13 firefighters were injured and half of the island of Kythera was scorched. 

Apostolos Voulgarakis, a wildfire expert at the Technical University of Crete and a co-author of the Imperial College study, notes the region around Athens has already lost over 40% of its forested area in less than a decade.

Europe’s record fire season is showing that climate change is loading the dice toward disaster, with even well-prepared countries struggling to keep forests safe. “In Greece we don’t have a particularly encouraging picture,” Voulgarakis said. “It’s been the third consecutive summer with a catastrophic fire season that’s in many ways unprecedented and hitting different parts of the country without any distinction.”

Fuel to the fire

Climate change made the extreme weather conditions that fueled the wildfires in Portugal and Spain about this many more times likely to happen, according to a report by the World Weather Attribution group.

Getting intense

"These fires are a sign of what is to come. With every fraction of a degree of warming, extreme, long-lasting heat waves will continue to intensify, increasing the chance of huge wildfires like the ones that burned vast areas of the Iberian Peninsula."

California’s hills are ready to burn

By Brian K Sullivan and Lauren Rosenthal

 Away from California’s coastline, the interior hillsides are a carpet of brown, dry brush and grasses.

Nearly 40% of the state is in drought, and with the state’s Santa Ana and Diablo winds set to pick up in the coming weeks, any errant spark threatens to race across a landscape ready to ignite.

“The grass levels are very thick, and the brush is very dry,” said David Acuna, spokesman and battalion chief for California Department of Forestry and Fire Protection, known as Cal Fire, comparing the state to a haystack.

California started 2025 with tragedy on the fire front, as 31 people died in the Los Angeles area from the Eaton and Palisades fires in January. The fires were the state’s second- and third-most destructive, according to Cal Fire. In all, 6,504 fires have burned so far in 2025. Through the end of August, they consumed 425,680 acres, which is more than last year but less than the five-year average of 772,489 for the same time period.

But the worst of California’s fire season is likely ahead as the windy season nears. Powerful, sustained wind events usually begin in October and spill over into early winter. Known as Santa Anas in Southern California and Diablo or Sundowner winds in other parts of the state, they’re driven by pockets of high pressure across Nevada and Utah that push winds west toward the Pacific. The winds gain speed as they cross mountains while also becoming drier and hotter as they roll down slopes. 

The other key ingredient for fires is fuel, and that’s abundant in California after several winters in a row of plentiful rainfall that’s allowed natural and invasive plants to thrive. Now, all that kindling is dry following the long, arid months of summer. Any fire “is going to grow exponentially,” Acuna said.
