The notion of climate services is emerging in research and public policies. The French research group AllEnvi defines Climate services as the whole information and services aimed at helping decisions in the fields of mitigation and adaptation to climate change. To feed these services and adapt them to a specific territory, there is a need for regionalized climate services data from both natural and social sciences. This raises several questions : what kind of climate data do social sciences produce ? How are they different from natural sciences data and how are they to be used through climate services ? This article presents the results of a research on these questions, through a literature review and 47 semi directive interviews held in France.
