An accurate forecasting of environmental impact on sea level and shoreline changes due to global warming, requires a detailed investigation and interpretation of the events that occurred during the past 20,000 years. This time interval in fact corresponds to two significant climatic global changes: the last Wuermian glaciation, during the Upper Pleistocene, and the warming during the Holocene. Examples of the climatic variation impact on paleoenvironments are here evidenced by sedimentological studies, radiocarbon dating, paleobotanic, paleontological, mineralogical and geochemical investigations of two stratigraphic columns that are geographically far apart: the Lagoon of Venice, Italy, and the Bohai Sea, China. The study focuses first on a general overview of the regional paleoclimatic history of these two core locations and their correlation with the sedimentological variations; second on some depositional events, such clay layers and beachrock formations, that carry the imprints of the climatic conditions. The results of this investigation may contribute to a better understanding of diagenetic processes, still not sufficiently described, caused by the climatic changes. Furthermore the study provided information that may be useful to a more complete overview of the environmental impact caused by natural global warming before the anthropogenic input.
