Some metals do a remarkable thing when they’re placed within a magnetic field: They heat up. Remove the magnetic field, and they grow cold.
It’s not difficult to see how this heating and cooling, known as the magnetocaloric effect, might be put to good use. Refrigerators and air conditioners could not only become more energy efficient but also be freed from century-old technology that relies on environmentally harmful refrigerants.
Researchers with Oak Ridge National Laboratory's Building Equipment Research Group are working with General Electric Appliances to produce a refrigerator based on the magnetocaloric effect....
States challenging the president's Clean Power Plan claim it would raise electricity prices and cost jobs, but two separate new studies say implementing the plan could do just the opposite. The Court of Appeals for the D.C. Circuit is hearing arguments today in a suit brought by 24 states and several corporations challenging the plan.
But according to Jennifer Kefer, the executive director of the Alliance for Industrial Efficiency, their report shows that putting the plan into action would be a win for business, workers, and the climate....
Illegal logging is on the decline, but severe weather events continue to degrade Mexico’s forests
Extreme weather is now a primary driver of forest degradation in key wintering habitat for monarch butterflies in Mexico, according to a new report.
Excessive winds and storms that knocked down trees played a significant role in the degradation of 178.7 acres of forest in the Monarch Butterfly Biosphere Reserve between 2015 and 2016. Felled trees made up 74.6% of the causes of degradation, followed by illegal logging at 16.4% and drought at 9%, according to the report by the WWF-Telmex-Telcel Foundation Alliance, the National Commission of Protected Natural Areas, and the Institute of Biology of the National Autonomous University of Mexico....
Brian May, guitarist of British rock group Queen, is taking a stand against Japan’s dolphin killing, saying the slaughter of animals should end in the same way society has turned against slavery or witch-burning.
“Every species, and every individual of every species, is worthy of respect,” May told The Associated Press on Friday while in Tokyo for Queen’s sell-out concerts at Budokan arena.
“This is not about countries. It’s about a section of humanity that doesn’t yet understand that animals have feelings, too.”
Iconic species is one step further away from extinction
In a welcome piece of good news for the world’s threatened wildlife, the giant panda has just been downgraded from ‘Endangered’ to ‘Vulnerable’ on the global list of species at risk of extinction, demonstrating how an integrated approach can help save our planet’s vanishing biodiversity.
The International Union for Conservation of Nature (IUCN) announced the positive change to the giant panda’s official status in the Red List of Threatened Species, pointing to the 17 per cent rise in the population in the decade up to 2014, when a nationwide census found 1,864 giant pandas in the wild in China....
Neil Young is joining the protest against the four-state Dakota Access pipeline with his new song, “Indian Givers.” The music video for the song shows clips of Young driving his car and footage of the recent anti-pipeline protests, including a man who chained himself to construction equipment last week.
This summer, Walmart released a list of ten high priority chemicals they’ve removed from home and personal care products, with details as to how the reductions were achieved, and the total volume of the chemicals removed. In total, 23.26 million pounds of these chemicals were removed from thousands of products. The clean-up was the long-awaited fruit of Walmart’s 2013 Sustainable Chemicals Policy, developed in partnership with the Environmental Defense Fund.
The Hershey Company announced it has been named again to the prestigious Dow Jones Sustainability World and North America Indices.
Hershey is one of only 11 companies from the Food, Beverage and Tobacco Industry in the World Index and ranked in the 91 percentile overall. The company received top scores in health and nutrition, packaging environmental impact, and water related risks categories.
This is the fourth consecutive year that Hershey has been included in the World Index and the fifth year for the North American Index....
This week, Pollution Prevention (P2) Week — September 19 to 25, you're urged to think of ways to prevent pollution in your world, innovate, do it the green way from the beginning! That's the key to saving our planet's resources and moving toward sustainability.
Yes it is that time of year again and the Clean Hands Coalition would like to remind you that “Clean hands prevent illness and save lives”! The CHC began May 1, 2003 under the umbrella of the Centers for Disease Control and Prevention, with a flurry of enthusiasm by many other Federal agencies, universities, professional societies, foundations and corporations around the US to create a portal for disseminating best practices in hand hygiene in the areas of food safety, healthcare and public health....
Making five Pennsylvania counties a top priority could help put the state back on track to meet its clean-water goals. The Clean Water Blueprint, a six-state agreement to reduce pollution and sediment flowing into Chesapeake Bay, is off course - and Pennsylvania is responsible for most of the excess.
Will Baker, president of the Chesapeake Bay Foundation, said he wants the U.S. Department of Agriculture immediately to commit an additional $20 million for use in the counties that are the largest sources of farm runoff....
The Department of Conservation and Natural Resources Thursday announced it has increased the reward for information leading to an arrest of those responsible for starting the Poconos Wildfires to $20,000.
The wildfire in Monroe and Pike counties burned 8,700 acres in late April and May and was the largest in DCNR’s history.
The cost of containing the fire has been set at $2 million for the wildfires in which more than 100 bureau personnel rotated in and out of fire scenes....
Since 1988, National Estuaries Week has celebrated the many ways we benefit from healthy, thriving coastal ecosystems. All throughout the country, local organizations including Restore America’s Estuaries member groups, National Estuarine Research Reserves and National Estuary Programs organize special events, like beach clean-ups, hikes, canoe and kayak trips, workshops and more to recognize the special role these places play in our everyday lives. National Estuaries Week is a terrific opportunity to learn more about estuaries and the perfect excuse to spend time on your local bay!...
The public comment period on the PennEast Pipeline Draft Environmental Impact Statement closed Monday, and one environmental group has mounted a major challenge to the project.
The Delaware Riverkeeper Network has submitted eighty pages of objections to the content and omissions of the draft EIS, prepared by the Federal Energy Regulatory Commission (FERC).
Maya van Rossum, the Delaware Riverkeeper, believes the document is so deficient that it violates the National Environmental Policy Act.
"It's got huge data gaps," she said. "It's wrong on the information all the way around, either because it's got misinformation or misleading information, or because it's missing the information altogether."
The developers of the project say the 115-mile, 36-inch diameter underground pipeline would reduce energy costs and support thousands of jobs....
National Drive Electric Week is coming up September 10-18. There are more than 200 events planned all across the country to showcase the speed, convenience, clean-air benefits, and fuel cost savings of electric vehicles through ride-and-drives and other great activities.
Rising sea levels from global climate change are threatening wildlife, recreation and economies along the America's eastern seacoast, but a new report outlines steps to reduce the impact and adapt to changes.
The National Wildlife Federation report, "Changing Tides," says sea levels could rise more than 6 feet by the end of this century.
According to Ray Najjar, a professor of oceanography at Penn State University, the impact on coastal areas of such a rapid increase could be devastating.
"The amount of damage that we see will depend first on how much sea level rises, and then second on how well prepared we are to handle that," he states....
