    [R]esearchers at MIT have analyzed dust deposited off the coast of west Africa over the last 240,000 years, and found that the Sahara, and North Africa in general, has swung between wet and dry climates every 20,000 years. They say that this climatic pendulum is mainly driven by changes to the Earth's axis as the planet orbits the sun, which in turn affect the distribution of sunlight between seasons—every 20,000 years, the Earth swings from more sunlight in summer to less, and back again. For North Africa, it is likely that, when the Earth is tilted to receive maximum summer...

    There is a lot more to Climate Change than the dire predictions that we will be eating each other by now. The Sahara Desert was once lush and green. Then the weather systems shifted and the once fertile land turns to desert. The Sphinx is believed to have the face of Khafra of the 4th dynasty during the Old Kingdom which was carved perhaps around 2500BC. Some believe that the Sphinx predates the Egyptians and was actually a lion because there appear to be what some claim are water erosion marks. If true, then the original Sphinx may have existed...

    Credit: Chris Ford via Flickr ====================================================================== Humans did not accelerate the decline of the 'Green Sahara' and may have managed to hold back the onset of the Sahara desert by around 500 years, according to new research led by UCL. The study by a team of geographers and archaeologists from UCL and King's College London, published in Nature Communications, suggests that early pastoralists in North Africa combined detailed knowledge of the environment with newly domesticated species to deal with the long-term drying trend. It is thought that early pastoralists in North Africa developed intricate ways to efficiently manage sparse...

    Spain’s foreign minister revealed that US President Donald Trump suggested building a wall along the Sahara desert to stem the arrival of migrants, as he plans to do on the Mexican border. “Closing ports is not a solution, and neither is building a wall along the Sahara like President Trump suggested to me recently,” Josep Borrell told a lunchtime gathering this week, according to a video released by Spanish media. “Just build a wall that borders the Sahara,” he quoted Trump as telling him. “But do you know how big the Sahara is?” the minister responded. He did not give...

    If you ever live at the shore, one thing that crops up in 13-year cycles is what they call Red Tide. The traditional explanation I have always heard is that is caused by farming and the runoff of their pesticides that contaminate the water. I use to hear that in New Jersey and the same thing in Florida. It seems to be linked to the same people who promote Global Warming who want us to starve and stop driving to work. I would ask, where is the runoff from farmers when there are none in this area? It would go...

    Energy generation by wind and solar farms could reduce carbon emissions and thus mitigate anthropogenic climate change. A new climate-modeling study, published in the journal Science, finds that large-scale installations of wind and solar farms in the Sahara Desert and the neighboring Sahel region — areas particularly desirable for such farms because of their vastness and lack of inhabitants — would increase local temperature, precipitation and vegetation. ..." “Our study is among the first to model the climate effects of wind and solar installations while taking into account how vegetation responds to changes in heat and precipitation,” Dr. Li said.“Previous...

    The problem of the wet Sahara by Michael Oard This article is from Journal of Creation 31(1):3–4 April 2017 Both creation and secular geologists agree the earth’s deserts and semi-arid areas were once well watered.1 Creation scientists attribute this to the ponding of water in enclosed basins during the run-off stage of the Flood and greater Ice Age precipitation. During this time the Great Salt Lake in Utah, USA, was about 12 times its current area and about 330 m deeper.2 Measuring the ancient shorelines in Death Valley, California, USA (figure 1), shows a lake once filled Death Valley 170...

    The team has been investigating findings from an ancient rock shelter at a site named Takarkori in south-western Libya. It is desert now, but earlier in the Holocene age [our present age], some 10,000 years ago, it was part of the "green Sahara" and wild cereals grew there. More than 200,000 seeds - in small circular concentrations - were discovered at Takarkori, which showed that hunter-gatherers developed an early form of agriculture by harvesting and storing crops. But an alternative possibility was that ants, which are capable of moving seeds, had been responsible for the concentrations...The site has yielded other...

    Why Humans Left Africa: Our Ancestors Watched Climate Change To Cold, Dry BY ELANA GLOWATZ @ELANAGLOW ON 10/05/17 AT 3:09 PM Early humans may have left Africa and spread all over the globe because their home climate was drying up. The idea comes from samples of marine sediment taken from northeastern Africa that show the area was cold and dry around 60,000 years ago, which is around the time humans might have migrated off that continent and into Europe and Asia. A team of scientists wrote in the journal Geology that after warm and wet conditions between 120,000 and 90,000...

    More Evidence of a Wet Sahara by Jake Hebert, Ph.D. * Scientists from the University of Arizona recently announced that what is now the Sahara desert was once wet and green and extended as far north as the Mediterranean Sea.1,2 The scientists examined chemical clues found within leaf waxes preserved in four marine sediment cores located off the northwestern African coast. Plants experience subtle changes in the chemical composition of their wax, depending upon the wetness or dryness of the climate. Because leaf wax washes into the oceans, it can be preserved in sediment cores extracted from the ocean floor....

    For the first time in 40 years, snow has fallen on the Sahara Desert, the Independent reported Wednesday. […] “In his images [Karim Bouchetat, an amateur photographer who captured images of the snow on Monday], a thin layer of snow rests on deep orange dunes, where he said it stayed for about a day, and forms whirling patterns where the slopes are too steep for it to settle. Snow was reportedly last seen in Ain Sefra in 1979, when a half-hour snowstorm stopped traffic,” the Independent stated in its article. …

    In the Sahara desert, known for its suffocating heat, a freak snow shower coated the dusty dunes near the Algerian town of Ain Sefra. It hadn’t snowed in the town called “The Gateway to the Desert” since 1979. Photographer Karim Bouchetata captured gorgeous images of the red rolling dunes frosted in white. “Everyone was stunned to see snow falling in the desert, it is such a rare occurrence,” Bouchetata told the Independent. “It looked amazing as the snow settled on the sand.”

    Source: Geological Society of America Date: August 30, 2007 Migration of Early Humans From Africa Aided By Wet Weather Science Daily — The African origin of early modern humans 200,000--150,000 years ago is now well documented, with archaeological data suggesting that a major migration from tropical east Africa to the Levant took place between 130,000 and 100,000 years ago via the presently hyper-arid Saharan-Arabian desert. This migration was dependent on the occurrence of wetter climate in the region. Whereas there is good evidence that the southern and central Saharan-Arabian desert experienced increased monsoon precipitation during this period, no unequivocal evidence...

Explorers stumbled across the tiny hand imprints in a Saharan cave after unearthing more than 5000 images carved into the stone in Egypt's southwest border with Libya 14 years ago. But a study of the 13 tiny hand prints show that not only are they not human - but that they are believed to belong...

    Paleontologists have discovered the fossil remains of the world’s biggest ocean-dwelling crocodile buried on the edge of the Sahara, a creature that was twice the size of anything seen today. Named Machimosaurus rex, this croc would have weighed in at least 6,600 pounds and been around 32 feet long. Other than its size, it would have looked much like a modern day crocodile except for its narrow snout – which was designed to allow it swim in the ocean.

    Discovery reports researchers documented a previously unknown system in which rain makes mushrooms grow, mushrooms release spores into the atmosphere, and those spores create moisture droplets that could lead to rain. “We can watch big water droplets grow as vapor condenses on (the mushroom spore’s) surface,” study author Nicholas Money tells Discovery. “Nothing else works like this in nature.” This process could be influencing climate patterns around the world, especially in fungus-heavy tropical forests like the Amazon, Gizmodo reports. According to Gizmodo, a single mushroom can "catapult" up to 30,000 spores per second at speeds of up to 4mph. And...

    Finding ways to create clean drinking water where there is none is a field of constant innovation. Desalination, the process of filtering seawater to make it fit for human use, is perhaps the most common and researchers around the globe are on a quest to bring cost-effective and portable desalination technology to rural areas where it is desperately needed. So it’s exciting news that researchers at Alexandria University in Egypt have developed a promising new method that can turn salt water into fresh water in just a few minutes. The new Egyptian method relies on salt-attracting membranes and vaporizing heat...
