Climate changes (CC) are expected affecting weather forcing regulating the triggering and reactivation of slope movements. The influence of CC on landslides can be different, according to the area, the time horizon of interest and the actual trends of socio-economic factors driving greenhouse gases concentration. However, even the simple identification of weather patterns regulating landslide occurrence represents a not trivial issue, also assuming steady conditions, due to crucial role played by geomorphological details.
In last years, such elements partly prevented the investigations aimed to assess how CC influence slope stability at different temporal and spatial scales.
In this regard, the Session has the main aim to gather test cases and investigations carried out in different geographical contexts in evaluation of ongoing and future landslide activity.
Researches may concern: (i) modeling of future slope stability conditions exploiting downscaled climate projections or (ii) analyses of historical records of landslides (using both historical research or paleo-evidences) and climate variables and their combinations.
Analysis at different detail from slope to regional scale to global scale, considering variations in landslide occurrence, frequency, susceptibility, hazard and risk result of interest. Nevertheless, studies considering the coupled effect of environmental (e.g., land use/cover) and climate changes will be taken into account.
