US has more oil spills than you think

The US has more oil spills than we thought and the number doubled after production increased six years ago. Richard Stover, PhD, and the Center for Biological Diversity counted nearly 8,000 significant incidents, between 1986 and 2014, in records of the pipeline safety administration. By “significant” they mean causing injury, death, damages exceeding $50,000 in value, a loss of 5 barrels of highly volatile substances, 50 barrels of other liquids or there was an explosion. There have been more than 500 human deaths and 2,300 injuries through-out that period. The number of plant and animal casualties is much higher.

Will Visitation at US National Parks Warm Up or Overheat?

Visitation at U.S. National Parks may potentially increase with increasing temperature in temperate areas, but may decrease with temperatures rising over 80 degrees Fahrenheit, according to a study using future climate and visitation modeling scenarios published June 17 in the open-access journal PLOS ONE by Nicholas Fisichelli and colleagues from U.S. National Park Service. 

Why does the Earth's core appear to be so light?

​The old tales may be true: There is brimstone in the underworld, and lots of it. Brimstone, the biblical name for sulfur, is often found near hot springs and volcanic fissures on Earth’s surface (above). But scientists studying the formation of Earth’s core have shown that the lightweight nonmetal might also be present there in vast quantities, answering a question that has long troubled earth scientists: How could Earth’s core—predominantly made of the heavy elements iron and nickel—appear as light as it does when analyzed using seismic waves? 

Researchers report online today and in the July issue of Geochemical Perspectives Letters that the answer may be sulfur trapped deep within Earth. To come up with their results, the team compared the proportions of copper isotopes in ancient meteorites—the presumed building blocks of our planet—with the proportions of copper isotopes in rocks originating from the mantle—the deep layer of viscous rock beneath Earth’s crust.

Bad News for Groundwater Basins

About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, despite having little accurate data about how much water remains in them, according to two new studies led by the University of California, Irvine (UCI), using data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. This means that significant segments of Earth's population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings are published today in Water Resources Research.

Focusing on Air Quality Could Prevent 2.1 million deaths per year

Improving air quality — in clean and dirty places — could potentially avoid millions of pollution-related deaths each year. That finding comes from a team of environmental engineering and public health researchers who developed a global model of how changes in outdoor air pollution could lead to changes in the rates of health problems such as heart attack, stroke and lung cancer. Outdoor particulate air pollution results in 3.2 million premature deaths annually, more than the combined impact of HIV-AIDS and malaria. The researchers found that meeting the World Health Organization’s (WHO) particulate air quality guidelines could prevent 2.1 million deaths per year related to outdoor air pollution.

We need to consider nature as capital to become more sustainable

Researchers today outlined in a series of reports how governments, organizations and corporations are successfully moving away from short-term exploitation of the natural world and embracing a long-term vision of “nature as capital” – the ultimate world bank upon which the health and prosperity of humans and the planet depend.

The reports, published in the Proceedings of the National Academy of Sciences, suggest that significant progress has been made in the past decade, and that people, policy-makers and leaders around the world are beginning to understand ecosystem services as far more than a tree to cut or fish to harvest.

Human Health Risks associated with Climate Change

From heat waves to damaged crops to asthma in children, climate change is a major public health concern, argues a Michigan State University researcher in a new study. Climate change is about more than melting ice caps and images of the Earth on fire, said Sean Valles, assistant professor in Lyman Briggs College and the Department of Philosophy, who believes bioethicists could help reframe current climate change discourse. “When we talk about climate change, we can’t just be talking about money and jobs and polar bears,” he said. “Why do we focus on polar bears? Why not kids? Climate change isn’t just people hurting polar bears. It’s people hurting people.”

EPA Tries to Regulate Airplane Emissions

The Environmental Protection Agency took its first steps toward regulating the greenhouse gas emissions that escape airplane engines and pollute the atmosphere. The EPA intends to update the Clean Air Act, which was first introduced in 1963, to include jurisdiction limiting the emissions from these plane engines.

Physical activity is good for you, should it be a public health policy priority?

Lack of physical activity – along with unhealthy diets – are key risk factors for major non-communicable diseases such as cardiovascular diseases, cancer, and diabetes, according to the World Health Organisation (WHO).

Thirty to 70% of EU citizens are currently overweight, while 10-30% are considered obese,according to the WHO, which warned against an obesity crisis in Europe over the coming decades.

To counter the “epidemic”, the WHO recommends 150 minutes of moderate physical activity each week. This, it argues, would reduce the risk of ischaemic heart disease by approximately 30%, the risk of diabetes by 27%, and the risk of breast and colon cancer by 21–25%.

Dogs don't like people who are not nice to their owners!

Dogs do not like people who are mean to their owners, Japanese researchers said Friday, and will refuse food offered by people who have snubbed their master.

The findings reveal that canines have the capacity to co-operate socially -- a characteristic found in a relatively small number of species, including humans and some other primates.
