Short summary
Data and climate simulations were used to discuss the West African Little Ice Age (LIA). We show a clear opposition between a dry Sahel–savannah zone and a humid equatorial sector. In the Sahel region, the LIA was characterized by a gradual drying trend starting in 1250 CE after two early warning signals since 1170 CE. A tipping point was reached at 1800 CE. Drying events punctuated the LIA, the largest of which dated to ca. 1600 CE and was also recorded in the savannah zone.
