Extended Data Figure 3: A contrast in hydroclimate history on the African continent.
From: A progressively wetter climate in southern East Africa over the past 1.3 million years
The leaf wax δ13C31 record indicates that the Malawi basin became progressively wetter since the Mid-Pleistocene Transition around 900 kyr ago (a), while much of the continent to the north of Lake Malawi maintained a trend towards drier conditions over the past three million years or more, as indicated by soil carbonate δ13C values in northern Tanzania, Kenya and Ethiopia (summarized in ref. 47) (b) and in marine sediment records of terrigenous dust input from northern Africa48, as shown in ODP Sites 721 and 722 from the Gulf of Aden (c).
