Are the Deserts Turning Greener?

Satellite pictures of northern Africa show that areas lost to the Sahara desert during decades of drought are turning green again.

Analysis of images show deserts retreating in a broad band stretching from Mauritania to Eritrea, according to research in British magazine New Scientist.

The evidence is limited and definitive conclusions are impossible to reach but recent satellite pictures of North Africa seem to show areas of the Sahara in retreat. It could be that an increase in rainfall has caused this effect.

“It’s not greening yet. But the desert expands and shrinks in relation to the amount of energy that is received by the Earth from the Sun, and this over many thousands of years,”
