The Great Desert Where Hippos Once Wallowed
The Sahara sets a standard for dry land. It’s the world’s largest desert. Relative humidity can drop into the low single digits. There are places where it rains only about once a century. There are people who reach the end of their lives without ever seeing water come from the sky.
Yet beneath the Sahara are vast aquifers of fresh water, enough liquid to fill a small sea. It is fossil water, a treasure laid down in prehistoric times, some of it possibly a million years old. Just 6,000 years ago, the Sahara was a much different place.
It was green. Prehistoric rock art in the Sahara shows something surprising: hippopotamuses, which need year-round water.
“We don’t have much evidence of a tropical paradise out there, but we had something perfectly liveable,” says Jennifer Smith, a geologist at Washington University in St Louis.
The green Sahara was the product of the migration of the paleo-monsoon. In the same way that ice ages come and go, so too do monsoons migrate north and south. The dynamics of earth’s motion are responsible. The tilt of the earth’s axis varies in a regular cycle — sometimes the planet is more tilted towards the sun, sometimes less so. The axis also wobbles like a spinning top. The date of the earth’s perihelion — its closest approach to the sun — varies in cycle as well.
At times when the Northern Hemisphere tilts sharply towards the sun and the planet makes its closest approach, the increased blast of sunlight during the north’s summer months can cause the African monsoon (which currently occurs between the Equator and roughly 17°N latitude) to shift to the north as it did 10,000 years ago, inundating North Africa.
Around 5,000 years ago the monsoon shifted dramatically southward again. The prehistoric inhabitants of the Sahara discovered that their relatively green surroundings were undergoing something worse than a drought (and perhaps they migrated towards the Nile Valley, where Egyptian culture began to flourish at around the same time).
“We’re learning, and only in recent years, that some climate changes in the past have been as rapid as anything underway today,” says Robert Giegengack, a University of Pennsylvania geologist.
As the land dried out and vegetation decreased, the soil lost its ability to hold water when it did rain. Fewer clouds formed from evaporation. When it rained, the water washed away and evaporated quickly. There was a kind of runaway drying effect. By 4,000 years ago the Sahara had become what it is today.
No one knows how human-driven climate change may alter the Sahara in the future. It’s something scientists can ponder while sipping bottled fossil water pumped from underground.
“It’s the best water in Egypt,” Giegengack said — clean, refreshing mineral water. If you want to drink something good, try the ancient buried treasure of the Sahara.

King Krishnadeva Raya would perform heavy exercises every morning. He regularly applied oil on his body and thereafter worked out till all the oil came out with the sweat. This was followed by a long ride on his horse. Once the king started leading a sedentary lifestyle, and he stopped exercising. He no longer went horse-riding either. The king overate and as a result grew fat and heavy. The king‟s temperament also underwent a sea change. Noticing this, the royal physicians cautioned the king against the ill effects of overeating and explained to him the risks posed by obesity. They advised the king to regulate his diet, exercise, and take care of his health. The repeated advice he got from the physicians to eat less made him so angry that one day he announced a reward for anyone who could find him an easy cure. But there was one condition: those who failed would have their heads off. None dared to advise the king in this regard. The situation became precarious and as usual Tenali Raman was approached by the courtiers for a remedy. Tenali heard the problem and assured the courtiers of a viable solution. The next day, an astrologer predicted that the king had only a month left to live. When the king came to know of this, he was furious. The astrologer was ordered by the king to be imprisoned for a month so that his prediction could be put to test and so the hapless forecaster was sent to prison. |
