Sahara Desert was 10 times as wet as today, claims study
The Sahara, world's largest hot desert, was a green area covered with vegetation 5,000 to 11,000 years ago, with rainfall up to ten times more than today's, a study has claimed. It used rainfall records to depict a 1000-year period about 8,000 years ago, when the Sahara became drier. The 1000-year dry period caused people to leave, scientists suggested.
