Monarch Butterflies need Endangered Species Act protection
August 28, 2014 09:49 AM - Alicia Graef, Care2

As monarch butterflies are beginning their epic migration from Canada and the U.S. to Mexico for the winter, concerns about the drastic rate at which they're disappearing from the landscape have led environmental and health organizations to petition the government for federal protection. This week, the Center for Biological Diversity, Center for Food Safety, Xerces Society and monarch scientist Dr. Lincoln Brower filed a legal petition with the U.S. Fish and Wildlife Service seeking protection for monarchs under the Endangered Species Act.

Mystery Behind Slithering Rocks of Death Valley Revealed
August 28, 2014 09:38 AM - Allison Winter, ENN

In California's Death Valley, a geological phenomenon exists. Sailing stones, or moving rocks can be observed on the valley floor inscribing long trails on the ground without human or animal intervention. For over 60 years of observations, no one has been able to uncover the mystery of what is actually pushing these stones across the sand. That is, until now.

Uncontrolled Trash Burning Significantly Worsens Air Pollution
August 26, 2014 04:20 PM - UCAR AtmosNews

Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world's garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.

How Cutting Emissions Pays Off
August 25, 2014 04:28 PM - Audrey Resutek, MIT News

Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions?

Drought Causes Western US to Rise
August 22, 2014 02:00 PM - Editor, ENN

Severe drought affecting the western United States in recent years is not only influencing water restrictions for residence and creating problems for crops and wildlife, but it's changing the landscape by causing land to rise up in elevation.

Study shows sunlight, not microbes dominate CO2 production in Arctic
August 21, 2014 03:38 PM - University of Michigan

Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible.

NASA reports unknown source of banned ozone-destroying compound
August 21, 2014 07:33 AM - ClickGreen Staff, ClickGreen

NASA research has revealed the Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012.

New Satellite To Help Farmers Facing Drought
August 19, 2014 09:08 AM - Allison Winter, ENN

Satellites are put into orbit for a variety of tasks. From sending television signals to our homes to enabling GPS devices, to helping us see weather on a global scale, satellites collect information and provide us with modern conveniences. One new use for a proposed satellite scheduled to launch this winter is soil moisture monitoring at a local level.

Harnessing High-Altitude Wind Energy
August 14, 2014 07:53 AM - ClickGreen Staff, ClickGreen

Researchers have discovered that the world's energy needs could easily be met by harnessing the power potential of high-altitude winds. Developers in an emerging field known as airborne wind energy envisage using devices that might look like parachutes or gliders to capture electricity from the strong, steady winds that blow well above the surface in certain regions.

Bottling Water from Drought Stricken Areas
August 12, 2014 07:55 AM - Leon Kaye, Triple Pundit

The bottled water industry has grown exponentially the past few decades despite the fact tap water in the United States is generally safe. Never mind the fact bottled water producers have had more than their fair share of safety issues: bottled water has become accepted by consumers. While companies such as Nestlé insist they are taking responsibility for water stewardship and recycling, they also bottle their water at dubious sources, including those in drought stricken regions.
