A challenge in assessing the impacts of climate change on the oceans
October 15, 2013 06:20 AM - ScienceDaily
Assessing the effect of climate change on upwelling ecosystems is essential to be able to predict the future of marine resources. The zones concerned by this upwelling of cold deep water, which is very rich in nutrients, provide up to 20 % of global production of fish. Since the 1990s, the theory adopted by the majority of the scientific community affirmed that these phenomena were intensifying. The rising temperatures of the air masses above the continents were expected to quicken the trade winds, which would in turn increase the upwellings, thereby cooling the surface water. But this theory has been contradicted by the recent work of researchers from the IRD and its partners.
Re-Inventing Small Manufacturing Towns in the 21st Century
October 14, 2013 02:27 PM - Skeo Solutions, Triple Pundit
Our company has seen firsthand the disastrous consequences that occur when financial gain is divorced from environmental and social considerations. Nowhere are these consequences more tragic than in former company towns that have gone bust — places created to concentrate workers on a singular economic enterprise, but are now landscapes of abandoned assets, economic atrophy and poisoned land and water. They include mining towns in the West and Appalachia, lumber towns in the Northwest, textile villages in New England and the Southeast, steel towns in the Rust Belt, and motor cities in the Midwest. These places struggle with the aftermath of environmental contamination, economic disinvestment and frayed social fabrics. More than anything, these communities are looking for new ways to build a secure and sustainable future.
Freeing the Elwha!
October 14, 2013 12:01 PM - Robin Blackstone, ENN
Exciting and dramatic changes have taken place in the Elwha River in the last two years with the removal of two dams. The Glines Canyon Dam (1927) and the Elwha Dam (1910) were removed to restore the watershed’s ecology unblocking passage for migratory salmon. Salmon have already begun to find their way up the newly freed river. Since the time of their building many things have changed about our understanding of river system ecology causing an ever-increasing movement to remove them. The Elwha River dam removal project is currently the largest one in history.
Sea and storm: coastal habitats offer strongest defense
October 14, 2013 08:51 AM - Liz Kimbrough, MONGABAY.COM
Surging storms and rising seas threaten millions of U.S. residents and billions of dollars in property along coastlines. The nation's strongest defense, according to a new study by scientists with the Natural Capital Project at the Stanford Woods Institute for the Environment, comes from natural coastal habitats. Of the 25 most densely populated counties in the United States, 23 of them are along the coastline. The study, "Coastal habitats shield people and property from sea-level rise and storms" published in Nature Climate Change, mapped the entire U.S. coastline and reports that habitats such as sea grasses, mangroves, sand dunes, and coral reefs currently protect two-thirds of the U.S. coastline, including at-risk areas such as New York and Florida.
Solar-powered car competition winner
October 14, 2013 06:22 AM - Tafline Laylin, Green Prophet
Stella, a solar-powered family car designed by students from the Eindhoven University of Technology (TU/e) in has won the World Solar Challenge 2013, ushering in a new era of efficient, practical cruisers that get all of their juice from the sun. Solar Team Eindhoven from the Netherlands spent over a year developing their family car, which features photovoltaic solar panels on both the roof and rear, according to Dezeen. The latter are flipped up to optimize solar absorption and generate energy while the car is not in use.
Time to standardize EV charging in America
October 12, 2013 07:34 AM - Brad Berman, Clean Techies
Hard data collected from plug-in vehicle owners shows that the majority of EV charging takes place at home. Still, the ability to charge an electric car along the road—even if infrequent—can extend the distance each car can travel over the course of a day. Unfortunately, the public charging landscape is littered with complications and inconveniences brought on by multiple standards and incompatibilities between different vehicles and charge providers. Imagine if each brand of gas station required its own subscription, and each brand of car was compatible only with a certain type of gas nozzle.
Weighing the Benefits of Wind
October 11, 2013 03:28 PM - Thembi Mutch, The Ecologist
There’s a new wind blowing across Europe. Windpower is predominantly located in Germany, Denmark and Spain, and a recent European Union report predicted wind will power Europe’s demands several times over before 2020. In September 2013 the 'Montreal Protocol' committed G20 countries to reducing the 'super Greenhouse Gases' - hydrofluorocarbons produced primarily from fossil fuels, and as part of this, alternatives to coal, natural gas and oil must be found, as a matter of urgency. However even here dissent prevails - the recent International Energy Outlook Report predicted that globally, we will remain 80% dependant on fossil fuels until 2040, (with China and Asia increasing their consumptions considerably) and the results are cataclysmic.
OSHA potentially lets West Fertilizer off cheap
October 11, 2013 12:44 PM - Robin Blackstone, ENN
On April 17, 2013 explosions rocked the small town of West, Texas. Fire fighters initially responded to a fire at West Fertilizer Company owned by Adair Grain, Inc. but as water was used to put the fire out, an explosion incurred taking with it a neighboring 50-unit apartment building and parts of a nearby middle school, as well as heavily damaging a nearby nursing home. With many lawsuits pending, OSHA has made its initial determination with regard to the West Fertilizer Company leading federal workplace safety regulators to propose initial fines in the amount of $118,300 against the company. This number, given the magnitude of the occurrence is thought to be extremely low.
Who is exposed to more pesticides, rural or urban dwellers?
October 11, 2013 06:19 AM - s.e. smith, Care2
Who has higher levels of pesticide exposure, New Yorkers or rural dwellers near commercial farms? The answer might surprise you: for at least two classes of pesticide, New Yorkers are actually more exposed, despite the fact that we associate pesticide use with the application of such chemicals to crops to protect them from destruction during growing and harvest season. Research on the subject has significant implications for pest management and environmental health. Where are all these pesticides in New York coming from, and what can we do about it?
A Comprehensive Energy Productivity Portfolio
October 10, 2013 03:17 PM - Robin Blackstone, ENN
Like a good financial portfolio, it appears that diversification is a successful strategy for America’s Energy Productivity according to the environmental action group, Natural Resources Defense Council. But, the NRDC notes that while the portfolio clearly should include a combination of all energies, the single most effective tool in maximizing our energy economy is to reduce consumption and extract the most out of every energy dollar spent.
