Recent satellite observations show a remarkable transformation in the Sahara Desert, with lakes like Sebkha el Melah in Algeria experiencing rare refilling events. This phenomenon offers insights into the region’s historical climate, highlighting the Sahara’s past as a greener landscape. Following heavy rainfall in September 2024, Sebkha el Melah was partially filled, covering 191 square kilometers to a depth of 2.2 meters. Researchers are exploring the implications of these events for understanding climate change and the Sahara’s future.
