In a low-emissions scenario (SSP1-2.6), the researchers calculate that roughly 39% more land would be burned per year by the end of the century compared with today's average.
In a high-emissions scenario (SSP3-7.0), it would be around 192%. While emissions reductions are crucial to reducing the impacts of fires, the results also show that improvements in prevention, early detection and firefighting have a key role in helping reduce the extent of the affected area. "Climate change is driving up fire activity across Europe as hot, dry and windy conditions become more severe," said Maik Billing, researcher at PIK and lead author of the study published today in Global Change Biology.
"Our results indicate there could be widespread increases in burned area even under comparatively low warming of around 1.8°C. But if we emit more, and global temperatures rise by roughly 3.6°C, we see fires become much more prevalent, especially around the Mediterranean and across much of Western and Central Europe, including areas that have not experienced many fires to date," Billing added. The researchers compared the projected annual average in 2070–2100 with the reference modeled period of 2000–2030.
The paper also employs a second approach developed by the Senckenberg co-authors that models the effects of human action to prevent, detect and fight fires in a world with higher temperatures. Continued improvements in fire management have the potential to reduce burned area by 92% in a 1.8°C future and 72% at roughly 3.6°C. However, the authors cautioned that the results could be optimistic when it comes to the efficacy of fire management in a much warmer climate.
"We see fire conditions worsening, so we need to invest more. If Europe increases investment in wildfire management—including training fire crews, proper equipment and good coordination—our projections show that this can make a significant difference. But if fires become really extreme, our ability to contain them might break down, and we do not yet know where this point is.
The recent record fires in France clearly show that we cannot simply extrapolate from the experiences of the past," commented Senckenberg scientist and study co-author Thomas Hickler. The findings come amid another severe wildfire season in Europe. According to the European Forest Fire Information System (EFFIS), around 550,000 hectares (1.36 million acres) have burned across the EU as of Aug. 12, 2026, about two and a half times the 20-year average for this point in the year.
