Sometime between 11,000 and 5,000 years ago, after the last ice age ended, the Sahara Desert transformed. Green vegetation grew atop the sandy dunes and increased rainfall turned arid caverns into lakes.
Summary: 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 desert was once green and lush with freshwater lakes the size of countries, fast-flowing rivers that cascaded down valleys, and forests so dense that you’d think you were in the Amazon.
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.
Researchers counted over 1.8 billion trees and shrubs in the 1.3 million square kilometer (501,933 square miles) area that covers the western-most portion of the Sahara Desert, the Sahel, and what are known as sub-humid zones of West Africa.
Was the Sahara desert ever a forest?
