Boat noise impacts development and survival of marine invertebrates
July 31, 2014 08:42 AM - University of Bristol
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study by researchers from the UK and France. While previous studies have shown that marine noise can affect animal movement and communication, with unknown ecological consequences, scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have demonstrated that boat noise stops embryonic development and increases larval mortality in sea hares.
CO2 decrease cause of Antarctic ice sheet growth in ice age
July 31, 2014 06:15 AM - University of New Hampshire via ScienceDaily
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels. In a paper published today in Nature, Matthew Huber of the UNH Institute for the Study of Earth, Oceans, and Space and department of Earth sciences provides evidence that the long-held, prevailing theory known as "Southern Ocean gateway opening" is not the best explanation for the climate shift that occurred during the Eocene-Oligocene transition when Earth's polar regions were ice-free.
Importance of Air Quality and Employee Productivity
July 30, 2014 09:19 PM - RP Siegel, Triple Pundit
A number of credible studies have shown that indoor air quality can have a significant effect on employee productivity. And we're not just talking about air that's so bad that you can't see or breathe. Generally speaking, OSHA takes cares of those (though I could tell you a story about an agricultural processing job I once worked in Arkansas). What we're talking about here is much more subtle than that.
Catching Waves in the Arctic
July 30, 2014 08:52 AM - University of Washington
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell — huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the Arctic Ocean, and detected house-sized waves during a September 2012 storm. The results were recently published in Geophysical Research Letters.
Green Turtle success story

More than 70 years after major turtle nesting beaches became protected on the remote UK overseas territory of Ascension Island researchers are now reporting a boom in population numbers. Scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s.
General Motors, OnStar, EV's and the Smart Grid
July 29, 2014 01:09 PM - Editor, Justmeans
General Motors is bringing its OnStar-enabled Smart Grid solutions, to one of the largest electric vehicle collaborations to take place within the industry. Eight global automakers, including GM, and 15 electric utilities are working with the Electric Power Research Institute to develop and implement a standardized Smart Grid integration platform. "One thing that’s missing from most Smart Grid programs is a sense of collaboration," said Tim Nixon, chief technology officer, Global Connected Consumer, GM. "Companies will showcase a meaningful solution, but without widespread acceptance in the industry, its usability is limited. That's what makes this partnership unique."
Turtle Talk: Exactly how do turtles communicate?
July 29, 2014 08:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
Do "Fat taxes" work?
July 28, 2014 02:55 PM - EurActiv
Specific taxes on sugar, salt or fat do cause reductions in consumption, the European Commission found in a new report. But higher taxes may also merely encourage consumers to go for cheaper products, it warned. The precise impact of such "fat taxes" on the competitiveness of the European agriculture and food sector still needs to be fully assessed, the report added.
Ozone + Rising Temperatures = Problems for Food Security
July 28, 2014 02:37 PM - Editor, ENN
A new study shows that interactions between increasing temperature and air pollution can be quite significant when it comes to addressing food security. Conducted in part by researchers at MIT, a study looked in detail at global production of four leading food crops — rice, wheat, corn, and soy. It predicts that effects will vary considerably from region to region, and that some of the crops are much more strongly affected by one or the other of the factors
Industrial lead pollution beat explorers to the South Pole by 22 years
July 28, 2014 08:58 AM - ClickGreen Staff, ClickGreen
Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of 1911. More than 100 years later, an international team of scientists led by Joe McConnell of Nevada's Desert Research Institute (DRI) have proven that air pollution from industrial activities arrived long before. Using data from 16 ice cores collected from widely spaced locations around the Antarctic continent, including the South Pole, McConnell's team created the most accurate and precise reconstruction to date of lead pollution over the Earth's southernmost continent.
