Whether during past climate stages or into a progressively warming world, changes in
precipitation constitute a key component of climatic change. Quantitative proxies for palaeo …

Current evidence suggests that all of the major events in hominin evolution have occurred in
East Africa. Over the last two decades, there has been intensive work undertaken to …

Abstract Study region East African Rift Valley basin. Study focus Water availability in the rift
valley relies heavily on the discharge from the highlands to rivers that run to the rift floor. This …

The environmental backdrop to the evolution and spread of early Homo sapiens in East
Africa is known mainly from isolated outcrops and distant marine sediment cores. Here we …

We synthesize African paleoclimate from 150 to 30 ka (thousand years ago) using 85
diverse datasets at a regional scale, testing for coherence with North Atlantic …

We analyzed published records of terrigenous dust flux from marine sediments off
subtropical West Africa, the eastern Mediterranean Sea, and the Arabian Sea, and lake …

Lake sediments in 10 Ethiopian, Kenyan, and Tanzanian rift basins suggest that there were
three humid periods at 2.7 to 2.5 million years ago (Ma), 1.9 to 1.7 Ma, and 1.1 to 0.9 Ma …

The late Cenozoic climate of East Africa is punctuated by episodes of short, alternating
periods of extreme wetness and aridity, superimposed on a regime of subdued moisture …

Potential paleoclimatic driving mechanisms acting on human evolution present an open
problem of cross-disciplinary scientific interest. The analysis of paleoclimate archives …

Magnetic and geochemical core data spanning the last 17,000 years are correlated with
new seismic stratigraphy from Lake Tana, Ethiopia, to infer past lake-level change and …
