Scientist's Terrifying New Discovery Under Sahara Desert Changes Everything

Cop 27 - Scientist's Terrifying New Discovery Under Sahara Desert Changes Everything. Looking at the Africa map, you can see a lot of greenery and lush flora to the south. However, things change when you travel north. The world's largest desert, spanning several nations and has miles and miles of dune creation. The Sahara Desert spans 9 million square kilometers, equivalent to 18 times the size of Spain. But did you know that thousands of years ago, this spacious area of infertile sand that makes up a third of Africa was covered with rich vegetation? Why did the Sahara disappear? And what is currently occurring to it?

The Atlantic Ocean borders the Sahara on the west, the Red Sea on the east, the Mediterranean on the north, and the Sahel Savannah on the south. Eleven nations are included in the vast desert. Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, and Tunisia.

The sand dune landscapes that are frequently depicted in movies are what make the Sahara Desert renowned. The sand dunes can rise as high as 183 meters or nearly 600 feet. They only cover around 15% of the entire desert, though. Mountain ranges, plateaus, plains covered in sand and gravel, salt flats, basins, and depressions are other topographical features in the Sahara Desert. How did the Sahara change from a tropical region to the harsh, arid place it is today? This question's answer takes us back in time by thousands of years.

The Sahara has experienced periodic dryness and humidity for a very long time. The tilt of the Earth's orbital axis, which alters the angle at which solar radiation enters the atmosphere, causes these variations. There have been periods of increased solar energy input throughout Earth's history that coincide with the West African monsoon season.
