The year 2022 is already "the hottest" never measured in France since the start of the statements in 1900, announced on Wednesday Météo-France, which believes that it is the "symptom of climate change in France" . According to the various hypotheses for December, the annual temperature of the entire year 2022 will be between 14.2 degrees Celsius (cold December) and 14.6 degrees (hot December). Far before the previous record of 2020 with 14.07 degrees. The year was marked by several episodes of heat: three waves this summer (June 15 to 19, July 12 to 25 and July 31 to August 13), a record of 33 days, and two out of season (in May and end october).

dangers from extraordinary heat and extreme events

"every month of the year were warmer than normal, at the 'Exception of the months of January and April "underlines Météo-France in a note. These extraordinary heat have been accompanied by many extreme events, such as a "historic dryness", forest fires, especially in Gironde and in regions usually little or not subject to this type of phenomena like Brittany, oceanic heat waves in the Mediterranean and Violent thunderstorms like that in Corsica on August 18 which had caused 5 dead.

Annual rainfall should present an average of a deficit of 15 to 25%compared to normal, with two months record in May (deficit of 60%) and July (-85%), which are the driest since the start of Measures in 1959. The driest year in France remains 1989, with a deficit of 25%. According to Météo-France, the hot weather has become more frequent in recent years: 8 of the hottest 10 years since the beginning of the 20th century are after 2010. This warming is favored by climate change of human origin. Thus the waves of summer heat of 2022 would have been "highly improbable and much less intense without the effect of climate change", indicates the public body.

Studies believe that this period "would have been almost impossible in a climate not warmed by humans": These heat episodes have been made "about 500 times more likely with climate change of anthropogenic origin", that is to say caused by humans, "and 1.5 to 1.9 degrees warmer". "Very hot in the current climate, the year 2022 will become + normal + in the middle of the 21st century", concludes Météo France.
