Late Holocene drought responsible for the collapse of Old World civilizations is recorded in an Italian cave flowstone
A severe drought in parts of low-latitude northeastern Africa and southwestern Asia ∼4200 yr ago caused major disruption to ancient civilizations. Stable isotope, trace element, and organic fluorescence data from a calcite flowstone collected from the well-watered Alpi Apuane karst of central-wester...
