Globally, fires in 2025 burned the second-lowest area on record since 2002 and emitted the third-lowest CO₂ total. Yet, a third successive year of extreme wildfire emissions prevailed in Canada, and catastrophic fires in Los Angeles, South Korea and Europe killed over 90 people and forced over 300,000 evacuations. At the global scale, land area burned by wildfire has declined in since 2002, mainly owing to reduced savannah burning in Africa. However, wildfires are expanding in extratropical forests, and show increasing intensity combined with extreme socioeconomic and environmental impacts1–3. In these areas, wildfire disasters are exacerbated by human land use and the wildland–urban interface4. Many regions are experiencing episodes of extreme wildfires with high rates of spread and intensity associated with substantial loss of life, infrastructure, or carbon stores, even in years with below-average burned area. These hallmarks define an era of declining global burned area but also of rising prominence of extreme and deadly wildfires.
