The modern, arid Sahara. The Sahara was not a desert during the African humid period. Instead, most of northern Africa was covered by grass, trees, and lakes. The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today.
In the southern Sahara, the drying trend was initially counteracted by the monsoon, which brought rain further north than it does today. By around 4200 BCE, however, the monsoon retreated south to approximately where it is today, [6] leading to the gradual desertification of the Sahara. [7] The Sahara is presently as dry as it was about 13,000 ...
Climate scientists used models to show historic intervals of a green, vegetated Sahara Desert that occur every 21,000 years. The Sahara Desert—Yes, That One—Remarkably Grows Green Every 21,000 ...
In 15,000 BP, the West African Monsoon transformed the landscape of Africa and began the Green Sahara period; greater rainfall during the summer season resulted in the growth of humid conditions (e.g., lakes, wetlands) and the savanna (e.g., grassland, shrubland) in North Africa. [2] Between 5500 BP and 4000 BP, the Green Sahara period ended. [2]
The African Humid Period occurred between 14,800 and 5,500 years ago, and was the last occurrence of a "green Sahara". Conditions in the Sahara during the African Humid Period were dominated by a strong North African Monsoon, resulting in larger annual rainfall totals compared to today's conditions. [ 17 ]
