Sea Turtles in Hawaii getting tumors and we are the cause
Hawai'i's sea turtles are afflicted with chronic and often lethal tumors caused by consuming non-native algae, "superweeds," along coastlines where nutrient pollution is unchecked. The disease that causes these tumors is considered the leading cause of death in endangered green sea turtles. The new research was just published in the scientific journal PeerJ. Turtles that graze on blooms of invasive seaweeds end up with a diet that is rich in a particular amino acid, arginine, which promotes the virus that creates the tumors. Scientists at the University of Hawai'i at MÄnoa and their NOAA colleague estimate that adult turtles foraging at high-nutrient grazing sites increase their arginine intake 17â€“26 g daily, up to 14 times the background level. >> Read the Full Article
Does the public trust what scientists say?
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. >> Read the Full Article
How Air Pollution Affects River-Flow
Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, according to the results of a new study. The paper shows how pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change. >> Read the Full Article
Dog waste contaminates our waterways
Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria â€” including antibiotic-resistant strains â€” that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology. >> Read the Full Article
It's important to ventilate if you are cooking with gas!
Cooking with gas is preferred by many cooks to alternatives. The popularity of "professional" stoves and cooktops with high-output burners makes cooking more fun perhaps, but those high-output burners also put out more contaminants. It is important to recognize this and to properly ventilate the cooking area with a hood that vents to the outside, or even a fan through the kitchen wall, or even a window. A new study by Oregon State University recommends that parents with children at home should use ventilation when cooking with a gas stove, after a new study showed an association between gas kitchen stove ventilation and asthma, asthma symptoms and chronic bronchitis. "In homes where a gas stove was used without venting, the prevalence of asthma and wheezing is higher than in homes where a gas stove was used with ventilation," said Ellen Smit, an associate professor in the College of Public Health and Human Sciences at OSU and one of the studyâ€™s authors. â€œParents of all children should use ventilation while using a gas stove." >> Read the Full Article
Chinese Now Emit More Carbon Per Capita Than Europeans
Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements. >> Read the Full Article
Action to limit CO2 emissions IS needed now!
Carbon dioxide emissions continue to track the high end of emission scenarios, eroding the chances to keep global warming below 2Â°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. >> Read the Full Article
Burlington, Vermont - Now 100% Powered by Renewable Energy
Burlington, Vermont, already considered to be one of the United States's most environmentally progressive cities, has added another line to its impressive green resume. Just recently, the city finalized its transition to relying 100% on renewable resources for its energy. Burlington is Vermont's large city, though that in itself is no big feat â€“ the city has a population of just 42,000. Then again, very few communities of even this size have managed to disassociate themselves from fossil fuels. In order to adequately tackle climate change, cities â€“ big and small â€“ need to prioritize finding and utilizing alternative energy solutions. Burlington had expressed a desire to commit to 100% renewable energy for more than a decade, but it became a real possibility when analysts discovered that it was not only a smart environmental choice, but financially viable, too. In the long run, both the city and residents will not be paying more for clean energy than they were when buying fossil fuels. >> Read the Full Article
Electric vehicles getting even "Greener"
Sixty percent of Americans now live in regions where electric vehicles (EVs) produce fewer heat-trapping global warming emissions per mile than the most efficient hybrids, according to an updated analysis from the Union of Concerned Scientists (UCS). In 2012, that number was just 45 percent. "Electric vehicles are doing more and more to fulfill their technological promise," said Don Anair, research director for UCS's Clean Vehicles Program. "If we want to reduce transportation pollution and oil use, a big part of the answer is to be like Bob Dylan and go electric." >> Read the Full Article
Air pollution found harmful to young brains
Findings by University of Montana Professor Dr. Lilian CalderÃ³n-GarcidueÃ±as, 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 Alzheimerâ€™s or Parkinsonâ€™s disease. CalderÃ³n-GarcidueÃ±asâ€™ 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." >> Read the Full Article
