Overview
- A multi-institution analysis using satellite data and AI across about 13,000 forest units projects annual damaged area rising roughly 20% under a 2°C pathway and more than doubling in higher‑warming scenarios near 4°C.
- Wildfires, storms and bark beetle outbreaks are expected to interact and intensify impacts, with the Mediterranean most exposed and northern Europe generally less affected though regional hotspots may emerge.
- Projected burned area increases from about 110,000 hectares per year at 2°C to roughly 230,000 hectares per year at 4°C, indicating fire will be a leading driver of future losses.
- Researchers warn that mounting disturbance will weaken forests’ carbon uptake and could push some areas from net sinks to net sources, with an estimated €250 billion economic toll for damage and forest conversion.
- The team combined satellite imagery with neural‑network simulations; separate peer‑reviewed research finds satellite‑based models can severely underestimate CO₂ from peat‑smoldering fires in boreal regions, by up to a factor of 14 in Sweden.
