Deux mille ans d'histoire du climat dans le Midi de la France : étude sédimentologique

摘要

Two Thousand Years of Climate History in Southern France The sedimentological study of deposits in two rock shelters in southern France - the Font-de-l'Oule in the Vaucluse and the Font-Juvenal in the Aude - makes it possible to establish a coherent sequence of climatic events spanning the last two millennia. There were two cold periods, beginning in the 7th and 14th centuries respectively, separated by a clearly identifiable climatic optimum between the 8th and 13th centuries. This optimum can apparently be divided into two parts. The anthropic deterioration of the landscape was a late phenomenon, whose acceleration - in both Provence and Languedoc, as paleobotanical research indicates - can be dated to the 13th-14th centuries.
