Whose research first explained why the Sahara once had lakes and grasslands?
Quick Answer
Paleoclimate researchers, especially including work by scientists such as Fritz Sterner and later teams using lake sediments and fossils, showed the Sahara has repeatedly become greener during wet climate periods.
The Full Story
Modern research has shown that the Sahara has not always been a desert; it has cycled between arid and much wetter states over thousands of years. Scientists studying lake beds, pollen, animal remains, and ancient shorelines found evidence of past savannas, rivers, and large lakes. These findings are part of a broader field of paleoclimate science rather than the work of a single person. The key idea is that shifts in monsoon patterns and Earth’s orbital cycles can turn the Sahara green and then dry it out again.
