The mineralogical and chemical compositions of dust particles depend on geographic locations. For example the sand in Middle East is mostly composed of silicate minerals, carbonates, oxides, sulfates, and salts in different proportions. In addition recent studies have shown organic nitrogen in rainwater is related to dust originating from Sahara desert dust [19-21]. These small and insoluble particles contain various soluble contaminants in their matrix and on their surface and may also be carriers of anthropogenic pollutants [22-24]. In addition, many microorganisms associated with these dusts can withstand environmental stresses such as high temperatures, ultraviolet (UV) radiation, and atmospheric transport...

By the time it floats down from the atmosphere it will have traveled more than 5,000 miles, CNN meteorologist Haley Brink said. While it sounds dramatic, it's actually pretty normal. Right now the cloud is in the middle of the Atlantic Ocean and is expected to drift over the U.S. by next Tuesday, the Houston Chronicle reported. It will most likely sap some of the humidity from the air, the Chronicle said. While its presence is usually innocuous, the dust can irritate people who have respiratory issues, depending on its concentration in the air, the Chronicle said. Saharan dust tends...

Once green, the Sahara expanded 5,500 years ago, leading ancient herders to follow the rain and grasslands south to eastern Africa. But about 2,000 years ago, their southward migration stalled out, stopped in its tracks, archaeologists presumed, by tsetse-infested bush and disease. As the theory goes, the tiny tsetse fly altered the course of history, stopping the spread of domesticated animal herding with a bite that carries sleeping sickness and nagana, diseases often fatal for the herder and the herded. Now, isotopic research on animal remains from a nearly 2,000-year-old settlement near Gogo Falls in the present-day bushy woodlands of...

June 09, 2003Disease DustupDust clouds may carry infectious organisms across oceans By Otto Pohl> Image: ORBITAL IMAGING CORPORATION Photo Researchers, Inc. SANDSTORM blows particulates out from the Sahara Desert in Africa (landmass at right) over the Canary Islands in the Atlantic Ocean. The storm occurred in February 2001. On February 11, 2001, an enormous cloud of dust whipped out of the Sahara Desert and moved north across the Atlantic, reaching the U.K. two days later. A few days afterward, counties across the island began reporting simultaneous outbreaks of foot-and-mouth disease, a viral sickness of livestock (sometimes confused with mad cow...

When the moon is high in the sky, it creates bulges in the planet's atmosphere that creates imperceptible changes in the amount of rain that falls below. New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain - though very slightly. ... Kohyama was studying atmospheric waves when he noticed a slight oscillation in the air pressure. He and co-author John (Michael) Wallace, a UW professor of atmospheric sciences, spent two years tracking down the phenomenon. Air pressure changes linked to the phases of the moon were first...

I now regard as established that Ahhiyawa of the Hittite texts refers to a Mycenaean Greek kingdom not located in Asia Minor. Those who wish to wait for the proverbial "smoking gun" may do so, but the circumstantial evidence is now overwhelming. The alternative hypothesis of Hajnal (2003: 40-42) of Ahhiyawa as a small city state of Cilicia is not credible. Hittite references show that Ahhiyawa was a formidable power influential in far western Asia Minor. I leave to others the problem of determining just which Mycenaean kingdom (or kingdoms) should be identified with the Ahhiyawa of the Hittite texts......

Genetic investigators say the partnership between people and the ancestors of today's donkeys was sealed not by monarchs trying to establish kingdoms, but by mobile, pastoral people who had to recruit animals to help them survive the harsh Saharan landscape in northern Africa more than 5,000 years ago. The findings, reported today by an international research team in Proceedings of the Royal Society B, paint a surprising picture of what small, isolated groups of people were able to accomplish when confronted with unpredictable storms and expanding desert. "It says those early people were quite innovative, more so than many people...

UNITED NATIONS (AP) _ A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of ″eco- refugees,′ ′ threatening political chaos, said Noel Brown, director of the New York office of the U.N. Environment Program, or UNEP. He said governments have a 10-year window of opportunity to solve the greenhouse effect before it goes beyond human control. As the warming melts polar icecaps, ocean levels will rise by...

[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...

(ON MONDAY 10-24-2016 OUR DAUGHTER TRACI'S BIRTHDAY I WROTE THE FOLLOWING): CALL BE CRAZY AND LAUGH, BUT I BELIEVE THAT WHICH THE WORLD CALLS THE EFFECTS OF GLOBAL WARMING IS ACTUALLY "THE EFFECTS OF GLOBAL DUSTING." TRUE, I'M NOT A METEOROLOGIST OR CLIMATE EXPERT, BUT NEITHER ARE THE ONE'S WITH DEGREES "LOL". I've made many such claims since I was a little boy and most have become reality as confirmed by science and other formal authorities, PLUS my own Family and Friends. My theory here is, due to there being more people on earth at this time than ever before...

How dust from the Sahara is fuelling the Amazon

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...
