Summary: 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-western Italy indicate that the
climatic event responsible for this drought was also recorded in mid-
latitude Europe. Although the timing of this event coincides with an
episode of increased ice-rafted debris to the subpolar North Atlantic,
the regional ocean-atmosphere response seems atypical of similar
Holocene ice-rafting events. Furthermore, comparison of the flowstone
data with other regional proxies suggests that the most extreme part of
the dry spell occurred toward the end of a longer-term climate anomaly.
