The report analyzes the July 2026 wildfires in France and Spain, finding that anthropogenic warming significantly increased the probability and intensity of the fire-conducive weather. In central Spain, similar conditions are now at least 20 times more likely than in a pre-industrial climate, while in southwest France, they are at least twice as likely. The study highlights a 'weather whiplash' pattern where above-average winter rainfall promoted biomass growth, followed by extreme heatwaves and drought that dried fuels. The impact was exacerbated by high human exposure due to population growth in the wildland-urban interface and the presence of flammable maritime pine monocultures in France. The fires caused severe air quality degradation, with PM2.5 levels in Bordeaux exceeding 'fair' thresholds by a factor of 20, leading to the first-ever distribution of the French strategic national reserve of FFP2 masks during an ambient pollution episode.
