• World's first cardboard vacuum cleaner unveiled

    A U.K. vacuum cleaner manufacturer will market a high performance vacuum cleaner constructed out of recycled and recyclable materials; the device was designed by an industrial design student; the corrugated cardboard panels that form the body of the machine are easily replaced if damaged and cost just a tenth of the price of an equivalent plastic panel

  • Montana floods exacerbate Exxon oil spill

    Flooding in Montana has exacerbated the effects of an oil spill and made clean up more difficult for Exxon Mobil; it is estimated that roughly 750 top 1,000 barrels of crude oil have leaked into the Yellowstone River near Billings, Montana; the pipeline has been shut down, but flooding in the area has made it difficult for clean-up crews to find the source of the leak

  • Japanese discovery could undermine China's rare earth dominance

    A new discovery by Japanese researchers could break China’s stranglehold over rare Earth metals; Japanese geologists say they have found large deposits of rare Earth minerals on the floor of the Pacific Ocean; it is estimated that the mud of the Pacific Ocean contains 100 billion tons of these minerals

  • Microalgae : Texas' next big cash crop

    There are an estimated 200,000 to 800,000 species of microalgae — microscopic algae that thrive in freshwater and marine systems; scientists say microalgae offers a huge, untapped source of fuel, food, feed, pharmaceuticals, and even pollution-busters; it is set to be Texas’ next big cash crop

  • Flights increase rain and snow near airports

    Areas near commercial airports experience a measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions; when planes fly through certain mid-level clouds, they force nearby air rapidly to expand and cool; this causes water droplets to freeze to ice and then turn to snow as they fall toward the ground, often leaving behind odd-shaped gaps in the clouds

  • Farm animal disease to increase with climate change

    Researchers looked at changes in the behavior of bluetongue — a viral disease of cattle and sheep — from the 1960s to the present day, as well as what could happen to the transmission of the virus forty years into the future; they found, for the first time, that an outbreak of a disease could be explained by changes to the climate

  • Disappearing La Niña blamed for U.S. disastrous weather since January

    La Niña and El Niño are opposite extremes of a great Pacific oscillation; every two to seven years, surface waters across the equatorial Pacific warm up (El Niño) and then they cool down again (La Niña); each condition has its own distinct effects on weather; La Niña was strong in December, but disappeared in January, leaving nothing to constrain the jet stream; the jet stream took advantage of the new freedom — with disastrous results for the weather

  • Official dispels government green procurement regulation myths

    The U.S. government owns or manages one in five acres in the United States, and is the largest domestic user of electricity; it is also one of the largest consumers of resources in the United States, purchasing on average $535 billion worth of goods each year; In 2009 President Obama issued an executive order requiring that all government agencies establish and implement plans to increase their environmental performance; speaking at the 2011 Security Industry Association’s (SIA) Government Summit to an audience of security professionals, a government official sought to clarify myths surrounding the government’s new green procurement regulations and assured government service providers that the rules would not drastically affect a company’s existing practices

  • China deploys drought relief team to country's north

    China’s northernmost provinces are still suffering from a prolonged drought that has been the country’s worst in fifty years; in the northern provinces and the autonomous regions of inner Mongolia more than 11.67 million people and 3.62 million livestock have been affected by the drought; nearly six million acres of the region’s crops have also been hit hard by the drought; the government has declared it a level-four emergency, the highest level, and is launching a full out emergency response plan to aid the beleaguered region

  • Record rise in sea level in two millennia

    An international research team of scientists has shown that the rate of sea-level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years and that there is a consistent link between changes in global mean surface temperature and sea level

  • New tool predicts drought

    Knowing when to instigate water saving measures in dry times will be easier from now on, following a breakthrough in drought prediction: an Australian researcher has developed a way to predict droughts six months before they begin

  • Strong 1Q growth for U.S. solar power, more expected

    The United States showed strong first quarter growth in solar panel capacity, increasing installations by 66 percent; the increase in solar capacity is due largely to falling panel prices and developers taking advantage of government incentives that were set to expire in 2010; analysts expect solar panel growth to increase throughout the year

  • Mississippi River floods to cause large Gulf of Mexico dead zone

    Hypoxia, which creates oceanic dead zones, is caused by excessive nutrient pollution, often from human activities such as agriculture, which results in too little oxygen to support most marine life in bottom and near-bottom water; scientists are predicting the dead zone area in the Gulf could measure between 8,500 and 9,421 square miles, or an area roughly the size of New Hampshire; the largest hypoxic zone measured to date occurred in 2002 and encompassed more than 8,400 square miles

  • Arizona wildfire now largest in state's history

    The Wallow wildfire in Arizona has continued to burn out of control and is now the largest fire in Arizona’s history; on Tuesday firefighters in Arizona reported that they had 18 percent of the fire contained; so far the blaze has burned 479,407 acres in the White Mountains of eastern Arizona; officials have evacuated thousands of residents from mountain towns and are urging residents to stay clear as the smoke has created dangerous air conditions

  • Report warns falling crop yields could spell disaster

    A recent study found that as temperatures continue to rise the geographical range of staple crops like corn and beans will become increasingly limited, potentially resulting in massive food shortages; there are currently fifty-six million people who lack food security as temperatures are expected to rise above 86° Fahrenheit; at that temperature, beans are no longer a viable crop, while rice and corn yields suffer
