Abstract

The State of Wildfires, established in 2023, is a joint initiative led by the Met Office, ECMWF , the University of East Anglia and UKCEH in collaboration with international partners, responding to the increasing frequency and severity of extreme wildfire events worldwide. The annual report reviews major wildfire activity from the previous year and identifies four regions that experienced particularly extreme fire–climate conditions. These regional case studies are informed by expert panels and supported by detailed analyses of fire occurrence, impacts, and associated climate drivers. For each region, the report assesses observed fire trends, impacts, underlying drivers, climate attribution, and future projections. In this talk, I will present key findings from the 2024–2025 report including major fires in LA, Brazil and the Congo, and share early results from analyses underway for the forthcoming 2025–2026 report.
