In France, on the topic of climate change, the geographer climatologists are focused on the description and explanation of climate variability at various temporal and spatial scales on last period. They are less interested in the forms of adaptation considering results of future climate simulations, as envisaged by numerical climate models. This discretion is explained by the lack of climate model precision at the scale of territories occupied by human societies, but also because geographer research have shown since long time that human societies – with their involvement in additional greenhouse effect- have a direct effect in many disasters, which affect them (construction in flood plains, agricultural production in regions where rainfall can be insufficient sometimes...).Geographer climatologists can use new models at more operational scales to purpose specific adaptation for each area and each economical sector. These investigations integrate numerical model simulation uncertainties, but also social group and physical environment particularities concerning by these changes. This is the condition for reflection about the identification of adaptation factors
