Résumé
In the context of climate change, studying coastal risks involves the hazard’s historical fluctuations to understand the ocean-climatic parameters that guide its variability. The talk focuses on the detection of historical extreme events in coastal depositional environments. Surveys in western France highlight threestormy periods at approximately 1330-1360 AD, 1570-1620 AD and 1690-1720 AD. They are part of climate pejoration phases; storm activity appears to increase during positive phases of North Atlantic Oscillation, but no strict correlations can be established. A dendrochronological approach is suggested to extract recent storms impacting dune stands in coastal environments.
