Sahara Desert History

6,000 years ago the Sahara Desert was tropical, so what happened?

As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world's weather patterns abruptly transformed the vegetated region into some of the driest land on Earth. Now a researcher is trying to uncover the clues responsible for this enormous climate transformation -- and the findings could lead to better rainfall predictions worldwide. Ref. Source 5g.

Did humans create the Sahara desert?

New research investigating the transition of the Sahara from a lush, green landscape 10,000 years ago to the arid conditions found today, suggests that humans may have played an active role in its desertification. Ref. Source 5a.

Unlocking the secrets of the Sahara. A peat bog in Romania provides a new insight into our knowledge of when the Sahara began to transform from grassland into the desert we know today, and the impact this had on dust deposition within Eastern Europe. Source 5s.

History Desert Sahara

Dust deposits give new insights into the history of the Sahara. Remote Saharan dust influences Earth's radiation budget and tropical North Atlantic ocean-atmosphere temperature variability that might even attenuate Hurricane activity. In a new research study an international team of geoscientists reconstructed the history of Saharan dust storms during the last 12,000 years. The researchers identified several millennial-scale phases of enhanced Saharan dust supplies during the transition of the former 'green Sahara' to the present-day hyper-arid desert. Source 4j.

History Desert Sahara

As history goes that is relatively recent. I mean, they are talking about the Sahara only becoming like we know it today around 4000 BC. That's a drop of water in the ocean of time that is Earth's history. I wonder what great changes our ancestors will know 6,000 years from now… if we don't kill each other first.

Sahara Desert History

The Sahara Desert is expanding. The Sahara Desert has expanded by about 10 percent since 1920, according to a new study. The research is the first to assess century-scale changes to the boundaries of the world's largest desert and suggests that other deserts could be expanding as well. Source 3e.

Sahara Desert History

New evidence of the Sahara's age. The Sahara Desert is vast, generously dusty, and surprisingly shy about its age. New research looking into what appears to be dust that the Sahara blew over to the Canary Islands is providing the first direct evidence from dry land that the age of the Sahara matches that found in deep-sea sediments: at least 4.6 million years old.
