| الوصف: | [Departement_IRSTEA]Territoires [TR1_IRSTEA]SEDYVIN ; Les émissions de gaz à effet de serre ont significativement changé le climat mondial et continueront à le faire dans l'avenir. L'augmentation de la fréquence, la durée ou la sévérité des sécheresses et des canicules pourraient fondamentalement changer la composition, la structure et la biogéographie des forêts de nombreuses régions. Il en résulte un accroissement potentiel de la mortalité des arbres, associée aux stress physiologiques et aux interactions avec d'autres processus comme des explosions démographiques d'insectes et les incendies. Malgré ce risque, les prévisions actuelles de mortalité d'arbre sont basées sur des modèles qui manquent fonctionnellement de réalismes. Il n'y a eu à ce jour aucune tentative de suivi global de la mortalité forestière induite par le climat. Nous présentons dans cet article la première évaluation mondiale des mortalités récentes d'arbres attribuées aux stress thermiques et hydriques. / Greenhouse gas emissions have significantly altered global climate, and will continue to do so in the future. Increases in the frequency, duration, and/or severity of drought and heat stress associated with climate change could fundamentally alter the composition, structure, and biogeography of forests in many regions. Of particular concern are potential increases in tree mortality associated with climate-induced physiological stress and interactions with other climate-mediated processes such as insect outbreaks and wildfire. Despite this risk, existing projections of tree mortality are based on models that lack functionally realistic mortality mechanisms, and there has been no attempt to track observations of climate-driven tree mortality globally. Here we present the first global assessment of recent tree mortality attributed to drought and heat stress. |
