Scientists Uncover Secrets of Sahara's Repeated Greening Cycles
New research, combining satellite data and ocean sediments, explains how the Sahara repeatedly transformed from a vast desert into a green landscape with rivers, lakes, and diverse ecosystems. This natural climate rhythm, driven by Earth's axial precession and plant feedback, occurred roughly every 20,000 years, though predicting the next 'Green Sahara' is complicated by other climate factors and human-driven change.
