Climate Transformation
The transformation from green savanna to harsh desert occurred due to gradual changes in Earth's orbital tilt and rotation, which altered monsoon patterns across North Africa. This shift reduced rainfall significantly, beginning around 7,000-5,000 years ago, and forced ancient human settlements to migrate toward river valleys like the Nile. Rock art discovered throughout the region depicts fishing scenes, swimming activities, and herds of wild animals – silent testimony to the Sahara's dramatically different ecological past and one of Earth's most remarkable climate transitions.
