6,000 years ago the Sahara Desert was tropical, so what happened? As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world’s weather patterns abruptly transformed the vegetated region into some of the driest land on Earth.
The Sahara, Mojave, Gobi, and other famous deserts haven’t always been grassless wastelands. Even the South Pole is thought to have been the site of a lush rain forest—and not too long ago, considering the planet is an estimated 4.5 billion years old.
6,000 years ago the Sahara Desert was tropical, so what happened? As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world’s weather patterns abruptly transformed the vegetated region into some of the driest land on Earth.
But around 10,500 years ago, a sudden burst of monsoon rains over the vast desert transformed the region into habitable land. This opened the door for humans to move into the area, as evidenced by the researcher’s 500 new radiocarbon dates of human and animal remains from more than 150 excavation sites.
Was the Sahara desert a forest at once?
No, around 11,000 years ago, the Sahara wasn’t a desert at all. Instead, it was covered in plant life. It also held bodies of water. There was even a “megalake” that covered over 42,000 square miles.
How was the Sahara desert in the past?
The Sahara Desert formed around 7 million years ago, as a great dust bowl sitting where the Tethys sea once soaked. This huge body of water separated the two supercontinents, Laurasia and Gondwana, resulting from the cleaving of Pangea by tectonic forces.
Did the Sahara desert used to be an ocean?

How was the Sahara created?
When the tilt decreased in severity the upper region of Africa stopped getting large monsoons, an important part of the ecosystem and vegetation that depended on the annual water surplus. Without these monsoons, plants couldn’t survive, soils couldn’t grow, and the Sahara began to form.
How did the Sahara become sand?
The sand is primarily derived from weathering of Cretaceous sandstones in North Africa. When these sandstones were deposited in the Cretaceous, the area where they are now was a shallow sea. The original source of the sand was the large mountain ranges that still exist in the central part of the Sahara.
What caused the desert to form?
A desert forms when there has been a shortage of rain for a long time. It may have different geological conformations – mainly due to the effect of the wind (wind erosion). There are sand deserts, called erg, rock deserts, called hammada, and pebble deserts, the serir.
Will the Sahara be green again?
The next time the Green Sahara could reappear is projected to happen again about 10,000 years from now in 12000 or 13000.
Was the Sahara once green?
About 14,500 to 5,000 years ago, North Africa was green with vegetation and the period is known as the Green Sahara or African Humid Period. Until now, researchers have assumed that the rain was brought by an enhanced summer monsoon.
