Environmental Roots of the Late Bronze Age Crisis
The pollen-derived climatic and agricultural proxies are plotted against time (1500–500 cal. BC). Radiocarbon dates for the ca. 300 year dry event are indicated with red stars. The time-window of the invasions at the Bronze-Iron Age boundary is framed by radiocarbon dates from the destruction layer (blue). At the top, the cross-correlogram shows the correlation between the pollen-derived proxy of moisture availability from Hala Sultan Tekke and that from Gibala-Tell Tweini. Vertical axes show correlation coefficients while horizontal axes show the lag (1 unit = 1 sample). Significance level P = 0.05.
