MedCLIVAR (Mediterranean Climate Variability and Predictability) is an international program, sponsored by the European Science Foundation and endorsed by CLIVAR, which aims at coordinating and promoting the study of the Mediterranean climate. The peculiar geographical location and the topographical features of the Mediterranean area makes it a region which is very sensible to global climate change. The vulnerability of Mediterranean environment and societies requires a consolidated knowledge of climate processes and evolution at regional scale. The main goals of MedCLIVAR include reconstruction of Mediterranean climate past evolution, description of patterns and mechanisms characterizing its space-time variability, understanding of regional climate dynamics and identification of the forcing responsible for observed and future changes. The networking activities of MedCLIVAR put together expertise in different research sectors and create a forum where to interchange the results and facilitate synergy.
