The whole continent of Africa (as every other continent) went through several major climate changes, small and big. Pretty sure there were at least five major turnovers from wet to dry climate and back since then, and numerous before.
The North African region was a lush verdant region 11,000 years ago, which is not so long ago considering humans already spread far and wide around that time.
Was that area a desert 250,000 years ago?

Fun fact, there are some theories that the Sahara desert was actually caused by over foraging from early goat herding.
So to a degree our ancestors may have already caused some climate change.
