How has the Sahara changed in recent year?

- The area of the Sahara is shrinking due to climate change.

- The Sahara has lost about 10% of its area in the past century, and it is expected to lose another 15-25% by the end of the century.

- Rainfall is decreasing, and the sun is getting hotter, which is causing vegetation to die and the desert to expand.

Shifting southward

- The Sahara is also shifting southward.

- The desert's southern boundary has moved about 100 kilometers south since the 1950s, and it is expected to move another 100-200 kilometers by the end of the century.

- This is due to the same climate changes that are causing the Sahara to shrink, such as decreasing rainfall and increasing temperatures.
