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.
Loss of ocean predators has impact on climate change strategies

Continued unsustainable harvesting of large predatory fish, including the culling of sharks, can have far-reaching consequences for the way we tackle climate change.
El Niño's role in Pacific Ocean sea level rise
September 26, 2015 06:35 AM - Universtiy of Hawaii
Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme interannual sea level swings. The culprit is a projected behavioral change of the El Niño phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and tide-gauge analysis by scientists Matthew Widlansky and Axel Timmermann at the International Pacific Research Center, University of Hawaiʻi at Mānoa, and their colleague Wenju Cai at Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia.
During El Niño, warm water and high sea levels shift eastward, leaving in their wake low sea levels in the western Pacific. Scientists have already shown that this east-west seesaw is often followed six months to a year later by a similar north-south sea level seesaw with water levels dropping by up to one foot (30 cm) in the Southern Hemisphere. Such sea level drops expose shallow marine ecosystems in South Pacific Islands, causing massive coral die-offs with a foul smelling tide called taimasa (pronounced [kai’ ma’sa]) by Samoans.
Emissions from Melting Permafrost Could Cost Trillions
September 24, 2015 03:03 PM - Leon Kaye, Triple Pundit
While rain forests have long scored attention for their role in trapping carbon, discussions concerning the Arctic have centered on whether or not, or how much, we are going to allow companies to drill for oil far up north. Now, scientists are suggesting the Arctic should have renewed focus for another reason: Climate change, accelerated by the melting of permafrost and resulting greenhouse gas emissions, could cost the global economy, in the long run, as much as $43 trillion.
'Wisdom index' indicates we are not prepared for tsunamis
September 23, 2015 08:51 AM - Northwestern University
The world may not be well prepared for the next significant tsunami, reports Northwestern University tsunami expert Emile A. Okal in a new study that includes a “wisdom index” for 17 tsunamis since 2004.
Rising sea levels and stronger storms increase flood danger

New research has found rising sea levels and stronger storms associated with climate change will produce longer-lasting, more intense periods of flooding.
Selectively logged Amazon forests play important role in climate
September 21, 2015 02:37 PM - Cell Press via EurekAlert!
With careful management, selectively logged tropical Amazonian forests can recover their carbon stocks within a cutting cycle of 20 to 30 years, according to researchers who report their findings in the Cell Press journal Current Biology on September 21. The findings show that sustainably logged tropical forests continue to play a key role in global carbon sequestration, with important implications for global climate.
Alarming report on the health of our oceans
September 20, 2015 06:29 AM - Alicia Graef, Care2
The sheer vastness of the oceans on this planet make it seem almost impossible that our actions could bring them to the point of no return, but a new report has found that we are causing an alarming decline of marine ecosystems and the species who rely on them.
According to the World Wildlife Fund‘s (WWF) recently released Living Blue Planet Report, marine populations have declined by an astonishing 49 percent between 1970 and 2012, with with some fish species, including tuna, declining by almost 75 percent.
