Six thousand years ago, the Sahara wasn’t a desert. Northern Africa was green, filled with rivers, lakes, wildlife, and early human societies. Subtle shifts in Earth’s orbit reshaped the climate and turned a fertile landscape into the world’s largest hot desert. The Sahara is younger than we think. #AfricanHumidPeriod #GreenSahara #AncientEarth #ClimateHistory #HumanOrigins
