Climat, changements climatiques, et impacts

Climat, changements climatiques, et impacts (Groupe C3i : Climatic change and climate impacts) www.unige.ch/climate Résumé Tandis que les signes de l influence humaine sur le climat deviennent de plus en plus évidents, la problématique aujourd hui n est plus de savoir si le climat se réchauffe, mais à quelle vitesse et de mesurer les impacts naturels, économiques et sociaux à l échelle régionale de changements aussi abrupts. Le Groupe C3i comprend aujourd hui 14 collaborateurs, dont 8 sont engagés sur des fonds de recherche externes. Outre le Professeur Martin Beniston, qui est également directeur de l ISE, le groupe comprend 4 MER, 3 Post-doc, et 6 doctorants. Les thèmes de recherches sur le changement climatique et ses impacts comprennent notamment : L estimation des tendances climatiques à l échelle européenne et alpine basés sur l observation La simulation mathématique d évènements extrêmes dans un climat plus chaud à l aide de modèles climatiques régionaux (développés en collaboration avec l Université du Québec à Montréal) L étude des impacts physiques et économiques des extrêmes climatiques sur le tourisme, les infrastructures et les forêts L étude des risques naturels face aux changements climatiques, en utilisant différentes techniques expérimentales et informatiques (collaboration avec Dendrolab, UNIBE) L étude des changements des ressources en eau dans des régions de montagne telles que les Alpes, les Andes, ou l Asie Centrale, ainsi que les conséquences de ces changements pour différents acteurs économiques (thèmes principaux du projet européen ACQWA coordonné à l ISE) L évaluation des impacts d un climat plus chaud sur la qualité de l eau dans les lacs suisses ; conséquences possibles pour la santé publique L analyse des changements de la gouvernance de l eau pour éviter des rivalités entre acteurs économiques confrontés à des changements dans la disponibilité de la ressource L analyse des risques glaciaires pour le stockage des déchets nucléaires, mandat avec la CEDRA (Coopérative pour l Entreposage des Déchets Radioactifs) L étude de la non-linéarité dans le système climatique, projet de recherche financé dans le cadre de CADMOS (Center for Advanced Modeling Science), utilisant les ordinateurs les plus puissants La consultation sur le plan fédéral et international en matière de science et de politique climatique

Réseaux de collaboration Dans le cadre de ses activités, le Groupe C3i collabore étroitement avec l Université du Québec à Montréal (UQAM), dont le modèle de climat que nous développons conjointement constitue l outil principal pour la recherche en simulations climatiques. En 2007, un accord formel de collaboration entre l UNIGE et l UQAM a été signé, permettant l échange de scientifiques et d étudiants entre les deux institutions partenaires. De leur côté, les projets européens coordonnés par l ISE se composent de nombreux partenaires à la fois européens et non européens. Parmi les partenaires avec lesquels le Groupe C3i a les liens les plus étroits, on peut citer : Grande-Bretagne : Universités d Exeter, de Reading, de Birmingham et de Dundee ; Hadley Centre for Climate Prediction, Exeter France : Institut Pierre-Simon Laplace, Paris ; Laboratoire des Sciences du Climat et de l Environnement, Issy-les- Moulineaux ; Météo France, Toulouse ; Laboratoire de Glaciologie et de Géophysique Environnementale, Grenoble Allemagne : Max-Planck-Institut für Meteorologie, Hambourg Italie : International Center for Theoretical Physics, Trieste ; Universités de Turin et de l Aquila ; Politecnico di Milano Espagne : Universidad Complutense, Madrid ; Instituto Pyrenaico de Ecologia, Saragosse Chili : CEAZA (Centre d études des zones arides), La Serena et CECS (Centre de recherches environnementales), Valdivia Inde : Indian Institute of Technology, New Delhi En Suisse, les principaux partenaires comprennent l ETH-Zurich, l Université de Berne, et l EPF-Lausanne. Services à la Cité La question climatique interpelle énormément les membres du public ainsi que le monde des décideurs politiques et économiques. Le groupe C3i est ainsi très sollicité par les médias ainsi que pour donner des conférences publiques ou ciblées par rapport aux autorités communales, cantonales ou fédérales. Depuis 5 ans, on peut relever les éléments suivants : Près de 100 interventions dans la presse écrite (romande, suisse, internationale) 60 interventions à la radio (RSR mais aussi radios locales et internationales telles que la BBC en Angleterre) 25 interventions à la TV (TSR mais aussi d autre chaînes, notamment françaises), ainsi qu un documentaire de 10 sur le projet ACQWA diffusé en 2010 sur EURONEWS Près de 75 conférences destinées au grand public 16 conférences ciblées pour diverses autorités suisses (y compris le président de la Confédération à l époque, Pascal Couchepin en décembre 2007) ou étrangères Divers Distinctions Martin Beniston Co-récipiendaire du Prix Nobel de la Paix en 2007 grâce à l attribution collective de ce prix aux membres actifs du GIEC Election à l Academia Europea (l Académie européenne des Sciences) Markus Stoffel Docteur honoris causa de l Université Babeş- Bolyai, à Cluj (Roumanie)
