Canada wildfire season already second worst on record as experts warn of ‘new reality'
More than 470 fires across the country are currently classified as 'out of control', according to the Canadian Interagency Forest Fire Centre (CIFFC).
7,318,421 hectares of land in Canada have burned due to wildfires this year – close to 78% more than the five-year average of 4,114,516 hectares, according to the CIFFC's latest data.
The 2025 fire season is only behind the explosive 2023 wildfire season, which resulted in an astounding 17,203,625 hectares burned.
'This is our new reality… the warmer it gets, the more fires we see,' said Mike Flannigan, the BC research chair for predictive services, emergency management and fire science at Thompson Rivers University in Kamloops.
A June analysis on the 2025 fire season in Canada published by United Nations University in Shibuya, Japan, concluded that the fires are a 'stark manifestation' of climate change and that warm, dry weather in the spring resulted in temperatures 2.5C above average.
The warmer temperatures extend the fire season and increase the frequency of lightning that sparks fires, said Flannigan. A hotter climate also causes the atmosphere to suck moisture out of fuel, dead vegetation and the forest floor – creating ideal conditions for fires to start, he explained.
'It means more of the material is dried out, is available to burn when the fire does come, it leads to bigger flames, higher intensity, which gets to be difficult to impossible to extinguish,' he said.
So far, the worst of the fires have been concentrated in the prairie provinces of Saskatchewan and Manitoba, which together account for about 60% of the hectares burned so far this year in Canada.
Tens of thousands of people in communities across the country have been evacuated due to the wildfires. In Saskatchewan, the Canadian Red Cross reported it had assisted more than 17,000 people in the province from over 6,700 households to evacuate.
Thirteen communities in north-west Saskatchewan are under an evacuation order, several of which are First Nations, according to the province. One of the most affected areas of this year's wildfire season in the province is Denare Beach, a north-eastern village that was mostly destroyed in June due to a blaze.
The season has also now hit the east coast of Canada, as wildfires are currently raging across Newfoundland and Labrador and several towns are under evacuation orders.
John Abatzoglou, a professor of complex systems management at the University of California, Merced, co-authored the June report from United Nations University.
Abatzoglou said this year's fire season is the third year in a row Canada has seen fire activity that is well above average. The fires are also causing widespread smoke to cascade from the country into the United States as well, prompting severe air quality warnings in several states this month, is also an indication of how the fires are hurting populations beyond evacuations.
It's an international element of the fires that officials are having to contend with on a wider scale, Abatzoglou said.
'This is a really key point that's different from other natural hazards and its ability to impact everything from quality of life to … human health and even mortality,' he said.
Governments and public health will have to address how to change public behaviour and public policy to contend with 'smoke days', where you have to stay inside, he said.
'I know communities that may not have great infiltration systems … so more efforts there to provide resources to communities so that they can be safe indoors during acute smoke periods.'

Volunteer firefighter dies as wildfires rage across heat-stricken Spain
MADRID, Aug 13 (Reuters) - A firefighting volunteer died from severe burns, while several people were hospitalised as dozens of wildfires fuelled by strong winds and scorching heat continued to rage across Spain on Wednesday. At least six large wildfires were still out of control on Wednesday, according to regional emergency services. The victim, a 35-year old volunteer, had been attempting to create firebreaks near the town of Nogarejas, in the north-central Castile and Leon region, when he became trapped in the blaze, regional officials said. The fire had two active fronts that were still out of control, as weather services forecast another day of strong winds and electric storms. Over 5,000 people have been evacuated in the region, which is Spain's largest, and efforts were being concentrated on preventing the flames from reaching smaller towns. Environment Minister Sara Aagesen told SER radio station that many fires across the country were suspected to be intentionally caused by arsonists due to their "virulence", but that it was too early to quantify these. On Monday, another fire had killed a man working at a horse stable on the outskirts of the Spanish capital Madrid and reached some houses and farms before it was contained. Northwestern Galicia's regional leader Alfonso Rueda said the situation there was "complicated" and that the weather "isn't helping", as six active fires affected a combined 10,000 hectares in Ourense province. Weather agency AEMET forecast "extreme" risk of wildfires across Spain on Wednesday.

Temperature records broken as extreme heat grips parts of Europe
Extreme heat is breaking temperature records across Europe, early measurements suggest, and driving bigger and stronger wildfires. In south-west France, records were broken on Monday in Angoulême, Bergerac, Bordeaux, Saint-Émilion and Saint-Girons. Météo France said the 'often remarkable, even unprecedented, maximum temperatures' in the region were 12C above the norm for the last few decades. In Croatia, air temperature records were set in Šibenik, at 39.5C, and Dubrovnik, at 38.9C, while large forest fires raged along its coasts and ripped through neighbouring countries in the Balkans. Beyond Europe, dozens of temperature records were broken across Canada, and record-breaking heat above 50C in Iraq was blamed for a nationwide blackout. The heatwave in southern Europe comes as Nordic countries recover from unprecedentedtemperatures above 30C in the Arctic Circle this month. Bob Ward, a policy director at the Grantham Research Institute, said: 'This summer, like every summer now, has been exceptional in terms of extreme heat around the world.' In Italy, where 16 of 27 major cities were placed under red heat alerts and a four-year-old boy died of heatstroke, and in Spain, where a man died in a wildfire after suffering burns on 98% of his body, the high heat did not break a large number of records but still rang alarm bells. 'The main characteristic [of the heatwave] is the length and extent rather than the intensity,' said José Camacho, a climate scientist and spokesperson for Aemet, the Spanish weather agency. 'But the temperatures are still very high.' In the south-west of France, 40% of a sample of weather stations recorded temperatures above 40C on Monday. Lauriane Batté, a climate scientist at Météo France, said it was too soon to say if records were being 'shattered' rather than simply broken, but said the geographic extent of the heat was significant. 'Unfortunately, it's to be expected,' she said, adding that more than half of the 51 heatwaves in France since 1947 had occurred in the last 15 years. 'Clearly, it's a sign that the climate is warming.' Sign up to Down to Earth The planet's most important stories. Get all the week's environment news - the good, the bad and the essential after newsletter promotion The hot weather across Europe has dried out vegetation and allowed wildfires to spread further, in what scientists have described as a 'molotov cocktail' of climatic conditions. EU fire scientists projected 'extreme to very extreme conditions' across the entire continent this week, with 'particularly severe' risks in much of southern Europe and high anomalies expected in parts of the Nordics. Wildfires in Europe have burned more than 400,000 hectares so far this year, according to data published on Tuesday, which is 87% more than the average for this time of year over the last two decades. High heat kills tens of thousands of people in Europe each year. Researchers estimate that dangerous temperatures in Europe will kill 8,000 to 80,000 more people a year by the end of the century as the lives lost to stronger heat outpace those saved from milder cold weather. Antonio Gasparrini, an epidemiologist at the London School of Hygiene & Tropical Medicine, said implementing effective and diverse public health measures was critical as heatwaves became more frequent. 'This is another extreme heatwave hitting Europe this summer,' he said. 'As in previous events in the past months, we can expect not just a substantial death toll but also strong geographical differentials in excess mortality.' Last week, the World Meteorological Organization said wildfires and poor air quality were compounding the negative health effects of extreme heat. It noted that temperatures during the first week of August reached more than 42C in parts of west Asia, southern central Asia, most of north Africa, southern Pakistan, and the south-west US, with local areas exceeding 45C. 'This is what climate change looks like,' Ward said. 'And it will only get worse.'

Thousands evacuated in Spain as deadly heatwave fans Mediterranean wildfires
The deadly heatwave fanning wildfires across the Mediterranean region has claimed at least three lives and forced thousands of people from their homes. Firefighters continued to battle blazes on Tuesday and authorities braced for further damage as temperatures in some areas surged well past 40C. In Spain, a Romanian man in his 50s died after suffering 98% burns while trying to rescue horses from a burning stable near Madrid on Monday night. A four-year-old boy who was found unconscious in his family's car in Sardinia died in Rome on Monday after suffering irreversible brain damage caused by heatstroke. And in Montenegro, one soldier died and another was seriously injured when their water tanker overturned while fighting wildfires in the hills north of the capital, Podgorica, on Tuesday. Scientist have warned that the heat currently affecting large parts of Europe is creating perfect conditions for wildfires and serving as another reminder of the climate emergency. 'Thanks to climate change, we now live in a significantly warmer world,' Akshay Deoras, a research scientist at the University of Reading's meteorology department told Agence France-Presse, adding that 'many still underestimate the danger'. The fire in Tres Cantos, near Madrid – which had been fuelled by winds of 70km/h (45mph) and which has devoured 1,000 hectares of land – was still not under control on Tuesday evening, when further strong gusts were expected. The regional government said it had recovered 150 dead sheep and 18 dead horses from the area. More than 3,700 people were evacuated from 16 municipalities amid dozens of reported blazes in the north-western region of Castilla y León, including one that damaged the Unesco world heritage-listed Roman-era mining site at Les Médulas. Authorities in neighbouring Galicia said the largest wildfire of the year had burned through 3,000 hectares of land in Ourense province. In the southern town of Tarifa, firefighters on the ground and in planes battled a fire that broke out on Monday, with 2,000 people evacuated. The blazes have led the interior ministry to declare a 'pre-emergency phase' to help coordinate emergency resources. The prime minister, Pedro Sánchez, offered his condolences to the family of the man who died after the Tres Cantos fire, and thanked the emergency services for their 'tireless efforts'. He urged people to recognise the seriousness of the situation. 'We're at extreme risk of forest fires,' he said in a message on X on Tuesday. 'Let's be very careful.' In neighbouring Portugal, firefighters were battling three large wildfires in the centre and north of the country. Authorities in Greece requested EU help as fires, fuelled by gale force winds, ripped across vast swathes of the western Peloponnese and emergency services ordered the evacuation of thousands of residents. Firefighters were also trying to contain blazes on the popular Ionian tourist islands of Zakynthos and Kefalonia. With gusts hampering firefighting efforts, emergency services ordered all hotels in the region of Agala and Keri on Zakynthos to temporarily close, forcing suitcase-wielding holidaymakers to flee and relocate to other areas. By late Tuesday, dozens of firefighters, supported by 15 fire trucks and eight water-bombing planes and helicopters, were still trying to douse the fast-moving flames. 'Everything that civil protection can offer is here but there are very strong winds and the fires are out of control,' said the island's mayor, Giorgos Stasinopoulos. 'We need a lot more air support, it's vital.' The fire service said it was also dealing with blazes farther north in Epirus, around Preveza and in the central region of Aetolia-Acarnania. Despite temperatures nudging 43C in some parts of the Peloponnese region of southern Greece on Tuesday – and the prolonged drought, which has produced highly flammable conditions on tinder-dry soil – officials described the outbreak of so many fires as 'suspiciously high'. Faced with an estimated 63 blazes erupting and firefighters confronting flames on 106 fronts, fire officers dispatched specialist teams to several of the stricken regions to investigate possible arson. In Albania, hundreds of firefighters and troops had subdued most of the nearly 40 fires that flared up in the past 24 hours, the defence ministry said, but more than a dozen were still active. Since the start of July, nearly 34,000 hectares have been scorched nationwide, according to the European Forest Fire Information System. Police say many of the blazes were deliberate, with more than 20 people arrested. In Croatia, about 150 firefighters spent Monday night defending homes near the port city of Split. In the north-western Turkish province of Çanakkale, more than 2,000 people were evacuated and 77 people treated in hospital for smoke inhalation after fires broke out near the tourist village of Güzelyalı, authorities said. Images on Turkish media showed homes and cars ablaze, while more than 760 firefighters, 10 planes, nine helicopters and more than 200 vehicles were deployed to battle the flames. Turkey this year experienced its hottest July since records began 55 years ago. In southern France, where temperature records were broken in at least four weather stations, the government called for vigilance. The south-western city of Bordeaux hit a record 41.6C on Monday, while all-time records were broken at meteorological stations in Bergerac, Cognac and Saint Girons, according to the national weather service, Météo France.
