Fracking Wells Could Pollute the Air Hundreds of Miles Away
2015-05-01 14:47:00| Climate Ark Climate Change & Global Warming Newsfeed
ThinkProgress: Air pollution from hydraulic fracturing operations can likely travel hundreds of miles, even into states with little or no fracking, a new study has found. The study, published in the journal Atmospheric Environment, looked at hourly measurements of air pollutants like ethane and methane - gases that are found in natural gas - in Baltimore, Maryland and Washington, D.C. between 2010 and 2013. It found that ethane measurements increased by 30 percent between 2010 and 2013 in the region. The...

Traffic emissions may pollute one in three Canadian homes
2015-04-21 18:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought--contributing to varying levels of air quality across cities. Past research on air pollution from vehicle tailpipes has shown poor air quality anywhere between 100 to 250 metres of major roadways. But in a paper published in the recent edition of the journal Atmospheric Pollution Research, U of T chemical engineer Greg Evans...

Monsoon Rains Decline as Humans Pollute the Atmosphere
2014-10-03 18:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment News Service: Emissions produced by human activities have caused annual monsoon rainfall to decline over the past 50 years, new research has found. In the second half of the 20th century, the levels of rain recorded during the Northern Hemisphere`s summer monsoon fell by as much as 10 percent, according to researchers at the University of Edinburgh. The scientists determined that emissions of tiny particles from human activities, known as anthropogenic aerosols, were the cause. Levels of aerosol emissions...

Fracking flowback could pollute groundwater with heavy metals
2014-06-25 11:56:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: The chemical makeup of wastewater generated by "hydrofracking" could cause the release of tiny particles in soils that often strongly bind heavy metals and pollutants, exacerbating the environmental risks during accidental spills, Cornell University researchers have found. Previous research has shown 10 to 40 percent of the water and chemical solution mixture injected at high pressure into deep rock strata, surges back to the surface during well development. Scientists at the College of Agriculture...

Princeton Study: Up to 900,000 Abandoned Oil and Gas Wells Pollute Pennsylvanias Air
2014-06-19 17:22:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Pennsylvania already has a fracking problem groups struggle to inspire politicians to address. Now, a Princeton University study shows that hundreds of thousands of abandoned oil wells are adding to the state`s pollution. CO2, Methane, and Brine Leakage through Subsurface Pathways: Exploring Modeling, Measurement and Policy Options is a first-of-its-kind study from Mary Klang that describes how abandoned oil wells serve as leakage pathways for carbon dioxide, methane, brine and more. Based...
