The temperature in the French Alps has increased from 1 to 3 degrees over the past forty years according to the mountains, "more than in the rest of France," says a study published Friday by Météo-France also showing a deficit of snow in recent years.
While the temperature has increased by 1 degree Celsius on French territory in a century, it has increased in the Alps, “to 1800 m during the winter”, by 1 to 3 degrees in the most recent 40 years.
This increase in temperatures is especially marked at the beginning and end of winter, and it has been particularly noticeable since the 80s and 90s. "The French Alps therefore appear to be very exposed to the warming of the atmosphere in winter", estimates Météo -France.
This climatological study of the Alps from 1958 to the present day, moreover, shows that “the most recent years appear to be mostly in deficit” in terms of snow cover.
According to its authors, researchers at the Météo-France Snow Study Center, located near Grenoble, there have been “particularly snowy winters from 40 to 1975 and a deficit of white gold from 1985 over the past 1987 years. to 1993 ”.
