The Dust Bowl drought of the 1930s was arguably one of the worst environmental disasters of the 20th century. New computer simulations reveal the whipped-up dust is what made the drought so severe. Scientists have known that poor land use and natural atmospheric conditions led to the rip-roaring dust storms in the Great Plains in the 1930s. Climate models in the past few years also have revealed the effect of sea surface temperatures on the Dust Bowl. "What is new and what had...

A team of scientists are set on finding out how sand from the Sahara Desert is affecting marine life, as well as learning more about the ocean's ability to soak up the greenhouse gas carbon dioxide.The researchers encountered two large sand storms during their cruise and recorded footage for BBC News.Eric Achterberg, principal scientist for the Natural Environment Research Council (Nerc) funded Solas (Surface Ocean Lower Atmosphere Study) expedition, said he was relieved to have encountered...

This summer, Mars suffered a titanic dust storm that engulfed the entire planet. The dust storm contributed to a temporary warming effect around Mars, which raised the temperature of the atmosphere by around 20-30°C. However, the surface temperature of the planet itself dropped. Imagine a dust cloud on Earth that started in the Sahara desert and grew to encompass our whole planet. Such a catastrophe would block sunlight from reaching the surface and plunge us into twilight for months. It...

The United Nation's World Meteorological Organization, or WMO, is launching an early warning system that can help Arizona and other states minimize hazards from intercontinental sand and dust storms. A University of Arizona research professor is leading the international team drafting the U.N. plan which will begin operation early next year. Storms generated in arid parts of the world can deposit thousands of tons of airborne sand and dust on cities and over continents. It exposes populations...

What happens to a hurricane when it gets hit by a dust storm? This is an important question because Atlantic hurricanes are born not far from the Sahara desert. To find the answer, NASA scientists recently flew into a dusty hurricane. NASA -- Throw gasoline on a fire, and the flames swell to a raging inferno. Throw dirt on a fire, and the flames suffocate. But what happens when you throw dirt on a hurricane? It's a serious question. Hurricanes are born in Atlantic waters just off the west...

A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one. In June and July 2006, there were several significant dust storms over the Sahara Desert in Africa. As this dust traveled westward into the Atlantic, satellite data show that the particles blocked sunlight from reaching the ocean surface, causing ocean waters to cool. These cooler waters may have impeded some storminess since hurricanes rely on warm...

When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. NASA researchers have found a similar process at work in the atmosphere: tiny particles in the air called aerosols can cause a rippling effect on the climate thousands of miles away from their source region. The researchers found that dust particles from the desert regions in northern Africa can produce climate changes as far away as the northern...

MADISON - After more than a dozen hurricanes battered the Atlantic Ocean last year, scientists are wondering what - if anything - might be causing stronger and more frequent storms. Some have pointed to rising ocean temperatures, brought on by global warming. Others say the upswing is simply part of a natural cycle in which hurricanes get worse for a decade or two before dying down again. Now, researchers at the University of Wisconsin-Madison have put forward an intriguing theory that...

BEIJING -- China's efforts to stop the spread of its deserts are reducing the severity of sandstorms like the one that dumped yellow grit as far away as Japan this week, but the problem cannot be entirely controlled, officials said Thursday. "The situation is still rather grave," Liu Tuo, deputy director of the Chinese State Forestry Administration's sandstorm-control agency, said at a news conference. China has planted thousands of acres of vegetation to stop the spread of deserts in its...

By Ben Blanchard BEIJING -- China, a third of whose landmass is desert, will never completely tame the sandstorms that plague the country every spring due to the sheer size of its sandy regions, officials said on Thursday. But the country will step up efforts to control the problem, and the officials said they were confident the 2008 Summer Olympics in Beijing would not be affected by the dust that enveloped parts of northern China this week. "Given the millions of square kilometers of desert...

Desert greening
2013-04-25 16:10:03

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
