This case study targets the Mediterranean cold water coral (CWC) habitats that develop under thermal conditions very close to 14°C. Maps of the current cold water coral distribution in the Mediterranean Sea will be correlated to physical parameters (i.e. Temperature) from field data and regional model Med-CORDEX. Considering that intermediate and deep water in the Mediterranean sea temperature is around 14°C, this suggests that most of the cold water coral species in the region thrive very close to their physiological threshold. Future scenarios are provided based on regional models (e.g. Med-CORDEX). the objective is to investigate future scenarios and predictions in case of a an increased of temperature and its consequents on CWC habitat loss.

Med-CORDEX initiative has been proposed by the Mediterranean climate research community as a follow-up of previous and existing initiatives. Med-CORDEX takes advantage of new very high-resolution Regional Climate Models (RCM, up to 10 km) and of new fully coupled Regional Climate System Models (RCSMs), coupling the various components of the regional climate
