Wildfires in southwest France generated pyrocumulonimbus clouds for the first reported time in the country, with one such cloud producing lightning that ignited additional fires. The fires burned more than 40,000 hectares, prompted the evacuation of approximately 220,000 people, and involved firefighting operations on July 27. Researcher Jean-Baptiste Filippi linked the event to human-related climate change, while verified mechanics confirm intense heat can loft such clouds regardless of long-term trends.
