• Potentially harmful chemicals widespread in household dust

    Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a study led by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust. They found that DEHP, a chemical belonging to a hazardous class called phthalates, was number one on that list. In addition, the researchers found that phthalates overall were found at the highest levels in dust followed by phenols and flame retardant chemicals.

  • 5 Species Most Likely to Survive a Climate Change Disaster

    Survival of the fittest. This basic tenet of evolution explains why the dodo bird no longer exists and why humans have opposable thumbs.

    Adaptation is key to survival, no matter how many fingers you’ve got. The ability to adjust to whatever conditions Mother Earth sends our way determines whether obstacles lead to extinction or to a new generation.

    Human-accelerated climate change is a disaster waiting to happen. We’ve already seen the superstorms and drought it can create. Although we can work to slow climate change, there’s no way to stop it completely. This reality means adaptation will once again become the most important strategy for survival.

    One thing’s for sure: the Earth will continue to exist as it has for eons. The question is, what will be left behind to inhabit it?

    Below are five species known for their resilience and ability to survive in adverse conditions. They are the most likely to survive a climate change disaster. Spoiler: humans don’t make the list.

  • 92% of the world's population exposed to unsafe levels of air pollution

    A new WHO air quality model confirms that 92% of the world's population lives in places where air quality levels exceed WHO limits. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together.

  • Longest record of continuous carbon flux data is now publicly available

    Around the world -- from tundra to tropical forests, and a variety of ecosystems in between -- environmental researchers have set up micrometeorological towers to monitor carbon, water, and energy fluxes, which are measurements of how carbon dioxide (CO2), water vapor and energy (heat) circulate between the soil, plants and atmosphere. Most of these sites have been continuously collecting data, some for nearly 25 years, monitoring ecosystem-level changes through periods of extreme droughts and rising global temperatures. Each of these sites contributes to a regional network -- i.e. the European Network (Euroflux) or the Americas Network (AmeriFlux) -- and the regional networks together comprise a global network called FLUXNET.

  • Thousands of Homes Keep Flooding, Yet They Keep Being Rebuilt Again

    The U.S. National Flood Insurance Program, which holds policies for more than 5 million homes, is $23 billion in debt after a string of natural disasters this century. As climate change further strains the program, analysts say it is time to shift its focus from rebuilding to mitigating risk.

    More than 2,100 properties across the U.S. enrolled in the National Flood Insurance Program have flooded and been rebuilt more than 10 times since 1978, according to a new analysis of insurance data by the Natural Resources Defense Council (NRDC). One home in Batchelor, Louisiana has flooded 40 times over the past four decades, receiving $428,379 in insurance payments. More than 30,000 properties in the program, run by the Federal Emergency Management Agency, have flooded multiple times over the years. Those homes, known as “severe repetitive loss properties,” make up just 0.6 percent of federal flood insurance policies. But they account for 10.6 percent of the program’s claims — totaling $5.5 billion in payments.

    The new data illustrates the serious problems facing the nation’s flood insurance program. The National Flood Insurance Program (NFIP), which currently provides policies for more than 5 million American homes, is $23 billion in debt following a string of major natural disasters over the last decades, including as Hurricanes Katrina and Sandy.

  • The double-edged sword of wildlife-friendly yards

    Hundreds of millions of birds are killed in collisions with windows each year in the U.S. alone, and although high-rise buildings tend to be the biggest individual culprits, the vast number of suburban homes across the continent means that even a few deaths per house add up fast. A new study in The Condor: Ornithological Applications examines the factors that affect window collision rates at homes and shows that yards that are more attractive to birds are also the sites of more collisions.

    Working with Alberta homeowners who collectively contributed more than 34,000 days' worth of collision data, Justine Kummer of the University of Alberta and her colleagues found that the presence of a bird feeder, whether a house was in an urban or rural area, and the height of the vegetation in the yard were the most important predictors of collisions. Of Alberta's 421 bird species, 53 were represented in the data, mostly common urban species.

  • Is your makeup killing sharks?

    Most animal lovers wouldn’t dream of harming an animal for fashion. Fur? No, thank you. Leather? I don’t think so. Yet they might be unknowingly killing sharks — and highly endangered kinds on top of that — for their beauty routine.

    Unbeknownst to most, one little ingredient in products like sunscreens, moisturizing lotions, lip balms, lipsticks and face creams is responsible for the death of over three million sharks annually.

    Killer ingredient

    “Squalene is a naturally occurring compound found in large quantities in the liver of sharks,” explains the shark protection group Shark Trust. “A sharks’ large oily liver helps to control its position in the water column, however many cosmetics companies use the oil (and an associated compound called squalane) as a base for their moisturizing and skin care creams, lipstick and gloss, as it is non-greasy and softens skin.”

  • Vermont will be the first US State to Label GMOs

    Vermont will soon be the first state in the nation to require labels on genetically modified (GMO) foods. Its GMO-labeling law, the first passed in the nation, goes into effect on July 1. Maine and Connecticut have since passed their own GMO-labeling laws. But they won’t go into effect until neighboring states pass similar legislation.

  • How Air Pollution Impacts Childhood Mental Health

    Air pollution is a known risk factor for certain mental health problems in adults, but a new study also links high rates of air pollution to poorer psychiatric health in children and adolescents.

    To investigate this link, researchers from Umeå University in Sweden examined what is known as “register-based” data. All medications given to Swedish people are registered, and in this case, researchers zeroed in on individuals under age 18 from Stockholm, Västra Götaland, Skåne and Västerbotten. They then looked at this information in connection with the Swedish National Register, which logs air pollution.

  • High blood pressure linked to short-, long-term exposure to some air pollutants

    High blood pressure was associated with short-term and long-term exposure to some air pollutants commonly associated with the burning/combustion of fossil fuels, dust and dirt, a new study shows. Researchers suggest people -- especially those with high blood pressure -- limit their time outdoors when pollution levels are high.
