Short summary
In 2022, southwestern France saw exceptional wildfires, burning an area about 14 times the regional average. Using fire records, weather data, and climate simulations with and without human influence, we show that human-caused climate change made the weather conditions linked to the 3 largest wildfires about 2 to 10 times more likely; such conditions could become roughly 10 to 100 times more probable by 2100 under moderate emissions, highlighting a growing need for prevention.
