- Climate change is increasing extreme fire weather during major heatwaves in temperate Europe.
- Fuel moisture content in live heather (Calluna vulgaris) is significantly associated with phenological variables, while dead fuel moisture is linked to weather variables.
- During the record 2022 heatwave, fuel moisture controls harmonized across different fuel constituents, driven solely by weather, leading to synchronized extreme dryness.
- Future intense summer heatwaves are expected to align severe conditions for fire ignition, spread, and impact in traditionally non-fire-prone regions.
- The study highlights the need for effective fuel management strategies to mitigate wildfire risks in humid temperate landscapes.
