Ten times as many days of heat waves and tropical nights, increased risk of forest fires across the country, up to two extra months of dry soil, more intense rain and less snow in the mountains... In a report published Thursday, March 20, France's national weather service, Météo-France, described the climate of a France at +4°C: a terrifying plunge into a future where climate disruption will increase risk across the board.

France, which is warming faster than the rest of the world, is preparing for a rise in temperature of 2°C in 2030, 2.7°C in 2050 and 4°C in 2100 compared to pre-industrial levels if the world's current climate policies continue.

This estimate of temperature increases was adopted in 2023 and is part of the third national climate change adaptation plan, the final version of which was presented on March 10. Météo-France, which is responsible for describing the climate and its impacts over those three timelines, had already delivered initial data on temperatures and precipitation at the end of 2024. It is now publishing results for a further 20 or so indicators, aimed at the general public and various stakeholders such as farmers and local authorities.
