Found the true age of the Sahara desert?

Climate models show that the Sahara desert seems to have formed about 7 million years ago, which is twice as old as it has been known for a long time.

According to common knowledge, North Africa is said to have begun to undergo desertification about 3 million years ago, leading to the birth of the Sahara desert.

However, scientists now seem to find that we have miscalculated the age of the world's largest subtropical desert.

Climate models show that the miniature process of the ancient Tethys sea along with the gradual rise of the Arabian Peninsula has weakened the monsoon phenomenon, leading to the formation of a large desert.

And this process has been identified that appeared 7 million years ago, according to a new report published in Nature.

The expert group of the Bjerknes Center for Climate Research in Bergen (Norway) draws this conclusion when analyzing data obtained from sediment dunes in northern Chad.

Other studies have also found evidence that widespread drought in the region began about 8 million years ago.
