Dans un communiqu\u00e9 du 7 novembre, le CNRS a fait la description de l\u2019une des \u00e9tudes de Brad Carlson<\/a>, charg\u00e9 de recherche au CREA Mont-Blanc d\u00e9tach\u00e9 du Laboratoire d’\u00c9cologie Alpine (LECA\/CNRS). Sp\u00e9cialiste de t\u00e9l\u00e9d\u00e9tection, le chercheur a utilis\u00e9 les images satellites de haute r\u00e9solution de la zone pour faire ce constat : les hautes montagnes de l\u2019Oisans (Parc national des \u00c9crins) sont plus vertes qu\u2019il y a trente ans.<\/p>\n

C\u2019est la premi\u00e8re fois qu\u2019une \u00e9tude de ce genre est r\u00e9alis\u00e9e dans les alpes alors que le ph\u00e9nom\u00e8ne est connu dans l\u2019Arctique. Contrairement \u00e0 une id\u00e9e r\u00e9pandue, les plantes de haute altitude sont parmi les grandes b\u00e9n\u00e9ficiaires du r\u00e9chauffement climatique observ\u00e9 ces derni\u00e8res d\u00e9cennies en Oisans. Avec la diminution de la dur\u00e9e d\u2019enneigement et le r\u00e9chauffement estival, les plantes colonisent de nouveaux habitats qui leur deviennent favorables.<\/p>\n

Ce travail de recherche a donn\u00e9 lieu \u00e0 une publication scientifique dans la revue Environmental Research Letters<\/em>.<\/p>\n
