Le changement climatique en Bretagne : cartographie sur la période observée (1951-2020) et future (2031-2100)

Abstract

Des cartes climatiques sont réalisées sur la Bretagne pour différents horizons temporels à une résolution spatiale de 1 km à partir d’une méthode de spatialisation géostatistique par régression multiple. Ces cartes montrent l’évolution du climat à plusieurs horizons temporels futurs selon différents scénarios d’émission de gaz à effet de serre. Avec une hausse de 0,9 à 1,1 °C, les températures moyennes annuelles actuelles du nord de la Bretagne correspondent à celles enregistrées dans le sud de la Bretagne dans les années 1950. En fin de siècle, avec une hausse de 1,1 à 3,3 °C (entre les périodes 1991-2020 et 2071-2100) selon le lieu et scénario, la région pourrait connaître les températures moyennes annuelles observées actuellement dans le Sud de la France. Concernant les précipitations, une tendance à l’amplification du contraste pluviométrique saisonnier devrait faire augmenter le risque de sécheresse sur la région.
