While southern Europe is used to summer fires, this year’s unusually dry/warm conditions from consecutive heatwaves are the main cause of the severe season.

Bellow 2025 FWI anomalies, a key indicator of fire-prone climate conditions and fire hotspots, largely overlapping with the anomalies.

A strong trend, but where exactly?

While climate appears to be the main driver, it is also important to consider exposure (WUI) and the vulnerability of buildings. Additionally, the models do not account for fire spread between buildings, which is challenging to predict due to the diversity of local factors.

The wildfires in Los Angeles during January of 2025 were extremely difficult to control. The extreme Fire Weather Index for this period of the year provides insight into the challenges faced.

Climate change made the LA fires 35% more likely “by reducing rainfall, drying out vegetation, and increasing the overlap between flammable drought conditions and strong Santa Ana winds.” https://www.worldweatherattribution.org/climate-change-increased-the-likelihood-of-wildfire-disaster-in-highly-…

Hi Tim ! can you add me to this list ? thank you
