The paper present results of cutting edge climate model simulations and reconstructions of volcanic eruption magnitude and timing to better understand the environmental context of the Ptolemaic era (305-30BCE). This important period of Ancient Egyptian history is known for its material and scientific advances, as well as for episodes of political and social unrest.
Short summary
This work is a modeling effort to investigate the hydroclimatic impacts of a volcanic quartet during 168–158 BCE over the Nile River basin in the context of Ancient Egypt's Ptolemaic era (305–30 BCE). The model simulated a robust surface cooling (~ 1.0–1.5 °C), suppressing the African monsoon (deficit of > 1 mm d−1 over East Africa) and agriculturally vital Nile summer flooding. Our result supports the hypothesized relation between volcanic eruptions, hydroclimatic shocks, and societal impacts.
