Scientists explore effects of large-scale wind and solar farms in the Sahara Desert. They found that such installations can significantly increase rainfall and boost vegetation in the region, paving the way for a 'green' Sahara, climate benefits, and clean energy.
New research suggests that the Sahara desert used to be moist and green before it has turned into one of the largest deserts on Earth. An analysis and simulation of weather patterns have indicated that a majority of the Sahara Desert has experienced very heavy and continuous rains more than a thousand years ago.
Scientists have discovered that the transport of Sahara Desert dust in the atmosphere may have crucially affected the changes in climate for thousands of years.
It's an archaeologists dream come true: A new intensive study of a massive outcrop of sandstone in the middle of the Saharan desert has revealed that it is covered in ancient stone tools, with an average of 75 distinct tools per square meter.
Iron, though present in miniscule amounts in seawater, is a major player in the ocean's carbon cycle. Now scientists have assessed the various sources of dissolved iron in the north Atlantic Ocean, finally tracing the source of this precious metal to the dusty Sahara Desert.
