What was the Sahara like 4000 years ago?
Using a new computer simulation of the Earth’s climate, German scientists say that the Sahara underwent a brutal climate change about 4,000 years ago. Over a very short time scale – possibly as short as 300 years – it went from grasslands with low shrubs to the desert we are familiar with today.
What was Sahara Desert before?

What happened to the Sahara around 3000 BC?
