Sahara Desert Used To Be a Lush Oasis


What Really Turned the Sahara Desert From a Green Oasis Into a Wasteland?

by Lorraine Boissoneault from March 2017

When most people imagine an archetypal desert landscape—with its relentless sun, rippling sand and hidden oases—they often picture the Sahara. But 11,000 years ago, what we know today as the world’s largest hot desert would’ve been unrecognizable. The now-dessicated northern strip of Africa was once green and alive, pocked with lakes, rivers, grasslands and even forests. So where did all that water go?

Archaeologist David Wright has an idea: Maybe humans and their goats tipped the balance, kick-starting this dramatic ecological transformation. In a new study in the journal Frontiers in Earth Science, Wright set out to argue that humans could be the answer to a question that has plagued archaeologists and paleoecologists for years.

The Sahara has long been subject to periodic bouts of humidity and aridity. These fluctuations are caused by slight wobbles in the tilt of the Earth’s orbital axis, which in turn changes the angle at which solar radiation penetrates the atmosphere.

  1. “…caused by slight wobbles in the tilt of the Earth’s orbital axis”, or the Earth’s rotational axis? Orbital doesn’t seem right. So, once again an ecologist, albeit a paleo one, blames anthropogenic activity. These people are a cult!

  2. The goats eat every thing that grows down to the roots and then the goat herder digs up the roots, than there is nothing. “land of the goats is a land of the poor”
