What is the Sahara, and how do the average temperatures there compare to the ones in the Antarctica?
That's interesting. Can you tell me more about the climate change that caused the desertification of the Sahara?
The desertification of the Sahara is believed to be the result of a combination of factors, including changes in the earth's orbit, changes in ocean currents, and human activities such as overgrazing and deforestation.
