Climatic changes and their impacts in the Mediterranean during the first millennium AD

Many events and developments in human history have been suspected to be, at least partly, influenced by climate and environmental changes. In order to investigate climate impacts on societies, reliable palaeoclimatic data of adequate dating precision, resolution, spatial representativeness, and so on, are needed. This paper presents a survey and analysis of published palaeoclimatic data of the Mediterranean for the 1st millennium AD, and identifies regional patterns of hydro-climate variability, useful for comparison with archaeological/historical studies. It also provides general guidelines to palaeoclimatic data for archaeologists/historians interested in climatic change. We conclude with a discussion of how the emerging patterns of regional climate histories may have had an impact on Mediterranean societies in Late Antiquity.
