An attribution study links climate change to the intensity of extreme fires in Spain and Portugal in August 2025
Climate change has made the hot, dry and windy weather conditions that spread fires across the Iberian Peninsula 40 times more frequent and 30% more intense than in the pre-industrial climate, according to a rapid study by World Weather Attribution. The ten-day heatwave was also 200 times more likely and 3°C hotter due to climate change. The study, which analysed weather observations rather than climate models, warns that fires in Europe are overwhelming firefighting resources and highlights the importance of controlling vegetation in affected areas.
