Resumo: | The effect of climate changes on marine ecosystems and the ecosystemic services identified in the framework of the World ecosystem assessment program for the millennium (MEA, 2001), is a major scientific issue. In the first place, it seems necessary to identify these changes' characteristics from a physics point of view, as well as from a specific biodiversity (e.g., species distribution areas, exotic and invasive species), populational or marine ecosystem functioning point of view (e.g., trophic chain). However, one of the main difficulties in assessing these impacts results from the superposition and the interactions between natural variability and the different anthropic effects including economic activities (e.g. fisheries). A number of doubts remain, especially as far as the ecosystems' retroactive effects in relation to climate change are concerned. These interactions between all those factors justify the ecosystemic approach currently followed by scientists but also by European policies. The development of a scientific program answering these doubts is all the more necessary as it provides some indicators and simulation devices enabling the elaboration of conservation, remediation and adaptation strategies taking into account the probable emergence of some extreme climatic events (e.g. protected marine areas, fishing quotas, farming structures). These strategies must integrate fully the economic dimension of climate change (action vs. inaction), including the economic value of biodiversity itself.
