What Could Be Causing It To Grow

The growth of the Sahara Desert is mainly driven by natural climate variability and human-induced climate change. Naturally, a process called the Atlantic Multidecadal Oscillation (AMO), a periodic climate cycle in the North Atlantic Ocean, significantly influences this expansion by affecting regional rainfall patterns. In the case of the Sahara, during warm phases of the AMO, this region experiences drier conditions, causing the desert landscape to spread.
