Can we reveal a sensitivity to climate change among populations living on the Breton coast? Do inhabitants of particularly vulnerable areas such as the Gâvres peninsula give special attention to their environment? These questions put climate change to the test of ambiences and atmospheres, ways of living and ways of sensing the coastline territory. An original in situ investigation has been experimented, related to a sensory ethnography and studying the embodided and situated character of the relation of the inhabitants to their surroundings. If sensitivity to climate change exists, we hypothesize that it is expressed in sensory perceptions, material traces, daily gestures, ordinary conversations, and local landscapes. Gâvres is characterized by the presence of natural elements, particularly water, sand and air. The notion of element then becomes a central notion to think the coastal environments and open to a sensory climate integrating both the physical and material components of the local ecology and the social and existential components of the surrounding environment.
