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 …

The recent decades-long decline in East African rainfall suggests that multidecadal
variability is an important component of the climate of this vulnerable region. Prior work …

East African landscapes today are the result of the cumulative effects of climate and land-
use change over millennial timescales. In this review, we compile archaeological and …

The response of the tropical climate in the Indian Ocean realm to abrupt climate change
events in the North Atlantic Ocean is contentious. Repositioning of the intertropical …
