The Sahara Desert was once covered in grassland that received plenty of rainfall, but shifts in weather patterns abruptly transformed the region into some of the driest land on Earth. 

An exceptionally rare sighting in the Gibson Desert.

It drinks rain and fog with its leaves.

Crossing the world’s largest hot desert in one fell swoop.

It turns out the phenomenon doesn’t occur just in Africa!

A once-in-a-lifetime event.

Earth appears to have a pair of lungs.
