Pronounced changes in African climate, deserts and tropical rain forest over the last glacial cycles presumably affected human’s way out of Africa. These changes were induced by large changes in ice masses, ocean circulation and monsoon dynamics which, in turn, were triggered by variations in the Earth orbit around the sun and subsequent alteration of meridional insolation gradients.

In this presentation, which focuses on numerical climate system simulations, the effect of climate changes on African vegetation and, in particular, the feedback of vegetation on climate is analysed. Evidence from geological records of abrupt climate changes and from pollen records of rather gradual transitions are critically assessed. Finally the possibility of human interference with African climate and vegetation will be discussed.
