• Tracing Individual Particulate Pollutants

    Air borne particulates come from both natural and man made sources. Their effects are similar from a health and esthetic point of view. Particle size is even more important. Scientists at the University of California, Davis, have, for the first time, developed a system that can determine which types of air particles that pollute the atmosphere are the most prevalent and most toxic. Previous research has shown that air pollution containing fine and ultrafine particles is associated with asthma, heart disease and premature death. This new study, released today by the California Air Resources Board and the Electric Power Research Institute, marks the first time that researchers have conducted source-oriented sampling of these particles in the atmosphere. >> Read the Full Article
  • Air Pollution and Heart Attacks

    There are many forms of air pollution. There is no doubt that air pollution is not healthy. The uncertainty is at what level is it an acceptable risk. The one of concern in this study is the finest of particulate matter. The largest study yet to investigate the links between fine air-borne particulate matter (PM) and patient survival after hospital admission for acute coronary syndrome (ACS) found death rates increased with increased exposure to PM2.5 – tiny particles that measure 2.5 micrometers in diameter or less, approximately 30 times smaller than a human hair. The amount of PM in the air is measured as micrograms per cubic meter of air. The main sources of PM2.5 are emissions from road traffic and industry, including power generation. >> Read the Full Article
  • Climate Change Adaptation for Agriculture, Forests

    The U.S. Department of Agriculture (USDA) on February 5 released "two comprehensive reports that synthesize the scientific literature on climate change effects and adaptation strategies for U.S. agriculture and forests." The effects of climate change will be profound and far-reaching, according to the two reports, which drew on more than 1,000 peer-reviewed studies carried out by scientists in federal service, universities, non-governmental organizations, industry, tribal lands and the private sector. >> Read the Full Article
  • Clean Coal Finally a Reality?

    A team of researchers at Ohio State University (OSU) spent the past 2 years developing a clean way of harnessing the power of coal and have recently found great success in their research scale combustion system. The team is now able to harness clean coal energy chemically without combustion with air, while capturing 99% of the carbon dioxide produced from the reaction. With the next stage in testing on the horizon, could this possibly be the future of coal? >> Read the Full Article
  • Over 35,000 march on Washington demanding climate action and rejection of Canada's 'carbon bomb'

    Yesterday over 35,000 people rallied in Washington D.C. for urgent action on climate change, which, according to organizers, was the largest climate march in U.S. history. Activists called on the Obama Administration to do much more to tackle climate change, including rejecting the Keystone XL Pipeline, which would bring carbon-heavy tar sands oil from Canada through the U.S. to a world market. >> Read the Full Article
  • Lead Pollution better, but still an issue

    Efforts to reduce lead pollution have paid off in many ways, yet the problem persists and will probably continue to affect the health of people and animals well into the future, according to experts speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Boston. "Things have substantially improved with the virtual elimination of leaded gasoline, restrictions on lead paint, and other efforts to limit releases of industrial lead into the environment. But the historic legacy of lead pollution persists, and new inputs of industrial lead are adding to it," said A. Russell Flegal, professor of environmental toxicology at the University of California, Santa Cruz. >> Read the Full Article
  • Marine pollution incidents kill thousands of seabirds - and it could be legal!

    Between 29 January and 6 February 2013, more than 500 seabirds, mainly guillemots, were killed or rendered helpless by a mystery substance from a pollution event off the south coast of England. Shockingly, these deaths and injuries may have resulted from legal shipping activity. The substance was subsequently identified as a man-made synthetic polymer known as polyisobutene, or PIB. This same substance has also caused the deaths of thousands of other seabirds in recent years in the Irish and North Seas. >> Read the Full Article
  • NASA Develops Aircraft Design that Uses 50 Percent Less Fuel

    It seems like new, innovative technologies to reduce our carbon footprint are always 10 years away. It's hard to imagine there won't be another amazing technology just around the corner. In this case, NASA has developed a manufacturing method for wing-shaped aircraft. When combined with an uber-efficient jet engine called an "ultra-high bypass ratio engine", this new design promises to cut fuel consumptions by half. >> Read the Full Article
  • Poll Reveals American Attitude Towards Climate Change, Support for Clean Energy

    Whether you believe climate change is occurring or not, according to a Duke University poll, the percentage of Americans who think climate change is occurring has reached its highest level since 2007. In recent years, the climate change debate has been a hot topic not only among scientists and experts in the field, but among political party lines. >> Read the Full Article
  • Wildflowers at risk from 'safe' levels of pollution

    New scientific research suggests that the impacts of nitrogen pollution may extend even further than previously thought. Dr Richard Payne and Professor Nancy Dise, of Manchester Metropolitan University, together with colleagues at Lancaster University and the Open University, studied more than 100 individual plant species' reactions to nitrogen deposition at 153 grassland sites across Europe. >> Read the Full Article
