Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln.

Quantifying CO2 from Streams
Work by a University of Wyoming professor and a recent UW Ph.D. graduate has provided a more complete picture of the role of rivers and streams in the global carbon cycle.
US EPA proposes regulations to reduce methane emissions from landfills
As part of the Administration's Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) issued two proposals to further reduce emissions of methane-rich gas from municipal solid waste (MSW) landfills. Under today’s proposals, new, modified and existing landfills would begin collecting and controlling landfill gas at emission levels nearly a third lower than current requirements.
Methane is a potent greenhouse gas with a global warming potential more than 25 times that of carbon dioxide. Climate change threatens the health and welfare of current and future generations. Children, older adults, people with heart or lung disease and people living in poverty may be most at risk from the health impacts of climate change. In addition to methane, landfills also emit other pollutants, including the air toxics benzene, toluene, ethylbenzene and vinyl chloride.
Neighborhood electric vehicles
While much of the focus of late has been upon mainstream electric vehicles it seems as though the popularity of Neighborhood electric vehicles continues to grow. These vehicles have a history which is far more successful than there larger electric vehicle counterparts but receive very little in the way publicity or promotion. The Global Electric Motor (GEM) brand is by far and away the best known brand in this particular sector having changed hands on numerous occasions in the past.
So, why is it that NEVs continue to sneak under the radar yet gain in popularity?
Which food wastes have greater environmental impacts?
Approximately 31 percent of food produced in the U.S., or 133 billion pounds of food worth $162 billion, was wasted in 2011 according to the United States Department of Agriculture (USDA). Now, University of Missouri researchers have found that the type of food wasted has a significant impact on the environment. Although less meat is wasted (on average) compared to fruits and vegetables, the researchers found that significantly more energy is used in the production of meat compared to the production of vegetables. This wasted energy is usually in the form of resources that can have negative impacts on the surrounding environment, such as diesel fuel or fertilizer being released into the environment.
Commentary on the US plan to reduce carbon emissions
President Obama's plan to cut greenhouse gas emissions may look like a climate victory, writes Tim Kruger - but it's no such thing. It's feeble because the US can meet its targets by reducing emissions to 2030 more slowly than it has since 2000. And it's fragile as any future President can scrap it at will.
Climate change-denying Republicans hate this plan (of course), therefore all good climate realists see it as a triumph. But it is a tiny, tiny step in the right direction and climatically immaterial.
No doubt, you heard the good news. Barack Obama has announced the US is pushing through plans to reduce emissions of greenhouse gases. Rejoice! Rejoice! We've got this climate problem licked - hurrah!
