Wildfires devastating richer areas but fewer hectares burned globally – study

“Devastating” wildfires ripped across the wealthier parts of the world in 2025, a study has found, even as globally, the area ravaged by flames fell. Catastrophic blazes claimed lives, homes and jobs last year in California , Canada, Europe and South Korea. But the 335m hectares burned was the second-lowest since 2002, the review found, largely owing to the expansion of African farms that have fragmented landscapes and hampered the spread of large savannah fires. The disasters in 2025 included a Scottish “megafire” that torched more than 100,000 hectares – contributing to the UK breaking its record for burned area – and the Palisades and Eaton fires in Los Angeles, which were among the most destructive in US history . Record-breaking blazes in Spain and Portugal burned more than half a million hectares, while South Korea had its biggest and deadliest wildfire season on record. Fires accounted for more than 38% of insured losses from weather disasters in 2025, the study found. “2025 shows that a ‘quiet’ fire year globally can still be devastating,” said Matthew Jones, a climate scientist at the University of East Anglia and lead author of the study. “We are seeing a growing disconnect between total area burned and real-world impacts.” A wildfire roars through Galloway forest park in Scotland on 7 April last year. …
