Which Form of Energy is the Cheapest?
October 16, 2014 10:47 PM - Kevin Mathews, Care2
Which kind of power is the cheapest? Listen to energy companies, and they'll insist that traditional forms like gas and coal are the way to go. Of course, they have money invested in keeping the existing systems in business. That's why the European Union commissioned an independent analysis to study the topic. According to the report, wind energy is the most cost-efficient way to supply power. When proponents of non-renewable energy point to costs, they intentionally overlook the overall economic impact that polluting causes. Once experts start to calculate the costs associated with public health and climate change that coincide with burning coal and gas, the true cost is far higher than initially reported. It's both irresponsible and shortsighted to ignore these environmental and health consequences from the equation.
Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.
California Becomes 1st State to Ban Plastic Bags
October 2, 2014 04:14 PM - Kevin Mathews, Care2
It's official: California is now the first state in the country to institute a statewide plastic bag ban! Though it took years for state legislators to pass this bill plus an additional month that felt like an eternity for the governor to sign the bill into law, environmentalists can finally rejoice in the knowledge that grocery store plastic bags will soon be a thing of the past. Analysts expect the legislation will eliminate at least 13 billion plastic bags per year. Don't expect to see a change immediately, however: the ban won't go into effect until next July. Liquor and convenience stores will have until July of 2016 to switch to paper or reusable bags.
Encouraging planting trees will sequester carbon and conserve habitat
September 23, 2014 04:00 PM - Oregon State University
Rewarding landowners for converting farmland into forest will be key to sequestering carbon and providing wildlife habitat, according to a new study by Oregon State University and collaborators. Current land-use trends in the United States will significantly increase urban land development by mid-century, along with a greater than 10 percent reduction in habitat of nearly 50 at-risk species, including amphibians, large predators and birds, said David Lewis, co-author of the study and an environmental economist in OSU's College of Agricultural Sciences.
Action to limit CO2 emissions IS needed now!
September 22, 2014 07:47 AM - ScienceDaily
Carbon dioxide emissions continue to track the high end of emission scenarios, eroding the chances to keep global warming below 2°C, and placing increased pressure on world leaders ahead of the United Nations Climate Summit on the 23rd September. Global carbon dioxide emissions from fossil fuel combustion and cement production grew 2.3 per cent to a record high of 36.1 billion tonnes CO2 in 2013. In 2014 emissions are set to increase a further 2.5%, 65 per cent above the level of 1990.
Climate March and Summit
September 17, 2014 09:08 AM - Editor, The Ecologist
This Sunday 21st September hundreds of thousands of people have pledged to march in New York, London, Amsterdam and many other cities around the world to demand climate justice, standing with climate and dirty energy-affected communities worldwide. They are hoping to influence world leaders gathering in New York for their one-day Climate Summit taking place on 23rd September to exceed the poor expectations vested in them.
Protected Areas Do Work, Says Study
September 16, 2014 12:17 PM - Jeremy Hance, MONGABAY.COM
Protected areas are working. That's the conclusion of a new analysis of over 80 different studies on the efficacy of parks and nature reserves in safeguarding wildlife. Published in the open access journal, PLOS ONE, the new study finds that in general protected areas house higher abundances of wildlife as well as greater biodiversity than adjacent areas.
National Chicken Council to Phase Out Some Poultry Antibiotics
September 16, 2014 08:47 AM - Jan Lee, Triple Pundit
Only about 10 percent of the antibiotics used in chicken are actually used in humans, says the National Chicken Council. Its statement comes on the heels of a controversial report by Reuters indicating increasing proof that the prophylactic medications used in chickens are fueling antibiotic resistance not just in fowl, but in humans as well.
Air pollution found harmful to young brains
September 15, 2014 04:19 PM - University of Montana via EurekAlert
Findings by University of Montana Professor Dr. Lilian Calderón-Garcidueñas, MA, MD, Ph.D., and her team of researchers reveal that children living in megacities are at increased risk for brain inflammation and neurodegenerative changes, including Alzheimer’s or Parkinson’s disease. Calderón-Garcidueñas’ findings are detailed in a paper titled "Air pollution and children: Neural and tight junction antibodies and combustion metals, the role of barrier breakdown and brain immunity in neurodegeneration."
Reducing Water Scarcity
August 29, 2014 02:53 PM - McGill University
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016. Irrigation techniques, industrial and residential habits combined with climate change lie at the root of the problem. But despite what appears to be an insurmountable problem, according to researchers from McGill and Utrecht University it is possible to turn the situation around and significantly reduce water scarcity in just over 35 years.
