Rainfall regimes of the Green Sahara
During the “Green Sahara” period (11,000 to 5000 years before the present), the Sahara
desert received high amounts of rainfall, supporting diverse vegetation, permanent lakes …

Atlantic forcing of persistent drought in West Africa
Although persistent drought in West Africa is well documented from the instrumental record
and has been primarily attributed to changing Atlantic sea surface temperatures, little is …

West African monsoon dynamics inferred from abrupt fluctuations of Lake Mega-Chad
From the deglacial period to the mid-Holocene, North Africa was characterized by much
wetter conditions than today. The broad timing of this period, termed the African Humid …

Coherent changes of southeastern equatorial and northern African rainfall during the last deglaciation
During the last deglaciation, wetter conditions developed abruptly~ 14,700 years ago in
southeastern equatorial and northern Africa and continued into the Holocene. Explaining the …

Sahel megadroughts triggered by glacial slowdowns of Atlantic meridional overturning
The influence of the large‐scale ocean circulation on Sahel rainfall is elusive because of the
shortness of the observational record. We reconstructed the history of eolian and fluvial …
