Abstract:
Today’s ice caps and glaciers in Africa are restricted to the highest peaks, but during the Pleistocene, several<br/> mountains on the continent were extensively glaciated. However, little is known about regional differences in the<br/> timing and extent of past glaciations and the impact of paleoclimatic changes on the afro-alpine environment and<br/> settlement history. Here, we present a glacial chronology for the Ethiopian Highlands in comparison with other<br/> East African Mountains. In the Ethiopian Highlands, glaciers reached their maximum 42 to 28 ka thousand years<br/> ago before the global Last Glacial Maximum. The local maximum was accompanied by a temperature depression<br/> of 4.4° to 6.0°C and a ~700-m downward shift of the afro-alpine vegetation belt, reshaping the human and natural<br/> habitats. The chronological comparison reveals that glaciers in Eastern Africa responded in a nonuniform way to<br/> past climatic changes, indicating a regionally varying influence of precipitation, temperature, and orography on<br/> paleoglacier dynamics.
