Arsenic found in many US red wines
October 7, 2015 09:11 AM - Jennifer Langston, University of Washington
A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.
The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.
Outsourcing manufacturing to China and the climate
October 6, 2015 07:40 AM - Belfer Center for Science and International Affairs, Harvard Kennedy School
In a study published today in the journal Nature Climate Change, scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere. The study, titled "Targeted opportunities to address the climate–trade dilemma in China," is available here.
"The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with tremendous quantities of lower-cost goods," said co-author Steven J. Davis, UCI assistant professor of Earth system science. "But all of this has come at substantial cost to the environment."
Noise pollution harms wildlife, degrades habitats
October 5, 2015 09:11 AM - Shreya Dasgupta, MONGABAY.COM
Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.
Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.
“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”
Could Mealworms Help Solve our Styrofoam Waste Problem?
October 2, 2015 03:16 PM - Kevin Mathews, Care2
Plastic waste is out of control in this country, and Styrofoam is one of the worst offenders. Americans toss out 25 billion Styrofoam cups each year. Over two million tons of the stuff ends up in landfills, where it does not biodegrade. Scientists think they may have found a solution for our Styrofoam problem, though: feed it to the worms!
The Volkswagen emissions cheating scandal and it's potential impact on VW owners
October 1, 2015 06:53 AM - YUKI NOGUCHI, NPR
Out of the 250 million cars and trucks on U.S. roads, the impending recall at Volkswagen will involve just a half-million of them. But VW's emissions cheating scandal is receiving outsize attention because many of the company's customers feel duped. Now those customers are weighing what it will take to make them feel whole again.
David Chien of Williston, Vt., was looking for a bigger, fuel-efficient car that could power its way through Northeastern snow. He says the 2013 Jetta SportWagen he bought "seemed to check all the boxes."
New water-tracing technology helps protect groundwater
September 30, 2015 04:18 PM - University of New South Wales via EurekAlert!
UNSW Australia researchers have used new water-tracing technology in the Sydney Basin for the first time to determine how groundwater moves in the different layers of rock below the surface.
The study provides a baseline against which any future impacts on groundwater from mining operations, groundwater abstraction or climate change can be assessed.
Background Ozone is a Major Issue on US West Coast
September 30, 2015 08:38 AM - NASA Jet Propulsion Laboratory
Levels of "background ozone" -- ozone pollution present in a region but not originating from local, human-produced sources -- are high enough in Northern California and Nevada that they leave little room for local ozone production under proposed stricter U.S. ground-level ozone standards, finds a new NASA-led study.
New England air quality update
September 29, 2015 07:27 AM - Roger Greenway, ENN
EPA today confirmed that New Englanders experienced a slight increase in the number of unhealthy air quality days this year, compared to 2014 and 2013.
Based on preliminary data collected between April and September 2015, there were 24 days when ozone monitors in New England recorded concentrations above levels considered healthy. By contrast, in 2014 there were a total of 9 unhealthy ozone days, and in 2013 there were a total of 20 such days.
The number of unhealthy ozone days in each state this summer is as follows:
- 22 days in Connecticut (compared to 8 in 2014, and 18 in 2013)
- 4 days in Rhode Island (0 in 2014, and 7 in 2013)
- 3 days in Massachusetts (0 in 2014, and 6 in 2013)
- 2 days in Maine (0 in 2014, and 5 in 2013)
- 2 days in New Hampshire (1 in 2014, and 3 in 2013)
- 0 days in Vermont (0 in both 2014, and 2013).
The Volkswagen scandal and EU transportation emissions
September 28, 2015 11:12 AM - EurActiv
The revelations that Volkswagen, the world's second largest car manufacturer, had routinely gamed US emissions testing has thrown the spotlight on the environmental and health impact of cars.
While EU member states, such as the UK, open or consider investigations into the beleaguered company, European Commission officials are currently reviewing the executive’s 2011 White Paper for transport, its main policy roadmap for the sector.
Bringing extra impetus to their deliberation is the upcoming UN Climate Change Conference in Paris, international talks aimed at capping global warming.
Just how much waste are Americans creating?
September 23, 2015 09:09 AM - Tex Dworkin, Care2
A new Yale-led study reveals that we’re disposing of more than twice as much solid waste as we thought we were here in the good ol’ U.S. of A.
Published on Sept. 21 in the Nature Climate Change journal and co-authored by Yale professor Julie Zimmerman and University of Florida professor Timothy G. Townsend, this study found that based on landfill measurements instead of government estimates, analysis of figures revealed that America tosses five pounds of trash per person per day.
Let that soak in for a moment. Five pounds of garbage. Per day. Per person. But it gets better, and by better, I mean worse.
