Plastic Particles More Prevalent Than Previously Thought

For decades, oceanographers have collected water samples from the surface of the ocean in order to record how much plastic debris currently litters the waters. But a new study asserts that surface collection alone is insufficient because high winds have a tremendous impact on the buoyancy of the plastic debris.

Warming Turns Tundra to Forest

In just a few decades shrubs in the Arctic tundra have turned into trees as a result of the warming Arctic climate, creating patches of forest which, if replicated across the tundra, would significantly accelerate global warming.

Study: Nuclear and Coal-Fired Electrical Plants Vulnerable to Climate Change

A study by European and University of Washington scientists published today in Nature Climate Change projects that in the next 50 years warmer water and lower flows will lead to more such power disruptions.

Plants Previously Thought to Be Stable Found to Be Responding to Climate Change

Many wild plant species thought to be "stable" in the face of climate change are actually responding to global warming, say researchers at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS).

Algae and Mosses Take Up Huge Amounts of Carbon Dioxide and Nitrogen

In cities, the presence of algae, lichens, and mosses is not considered desirable and they are often removed from roofs and walls. It is, however, totally unfair to consider these cryptogamic covers, as the flat growths are referred to in scientific terms, just a nuisance.

Maine Garbage Study Shows 60 Percent of Trash Could Be Diverted

Since municipalities pay for trash disposal, usually by the ton, researchers say big savings could result from reducing volume of trash, along with the cost of hauling it and paying tipping fees for disposal, in addition to improving the environment.

The U.S. Environmental Protection Agency is providing a total of $970,000 to New York City and Ogdensburg, New York to clean up abandoned and contaminated sites.

New Small Solid Oxide Fuel Cell Reaches Record Efficiency

Individual homes and entire neighborhoods could be powered with a new, small-scale solid oxide fuel cell system that achieves up to 57 percent efficiency, significantly higher than the 30 to 50 percent efficiencies previously reported for other solid oxide fuel cell systems of its size.

Why Wildfire is Important to the Ecosystem

Researchers studying Lake Tahoe have found that not only could a major disturbance like a fire affect Lake Tahoe, but so too could a lack of disturbance -- the absence of a fire.

Salt Lake and Ogden Receive $1.3 Million to Revitalize Contaminated Properties

U.S. Environmental Protection Agency Regional Administrator Jim Martin presented the Mayors of Salt Lake City, Salt Lake County and Ogden City with $1.3 million in grant awards to advance the assessment, cleanup and redevelopment of properties.

Children Exposed to Pollutant Found in Tobacco Show Signs of Chromosomal Damage

According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs.

EPA Awards Brownfields Grant to Mt. Shasta to Clean Up Toxic Lumber Mill

Today, the U.S. Environmental Protection Agency (EPA) announced approximately $3.8 million in new pilot grants to nine recipients across the country for cleanup and redevelopment of contaminated properties. One of the grants will go to the City of Mt. Shasta, Calif.

PCB Exposure Linked to Increased Abdominal Fat

There is a correlation between high levels of the environmental toxin PCB and the distribution of body fat to the abdomen, according to a new study published May 29 in the scientific journal Obesity.

Researchers Studying Impacts of Pharmaceutical Chemicals and Products on Environment

Researchers at the University of York headed a major international review aimed at enhancing efforts to better understand the impacts of chemicals used in pharmaceuticals or in personal care products, such as cosmetics, soaps, perfumes, deodorants and toothpastes (PPCPs), on the natural environment.

Two Houston Companies Will Pay $1 Million for Natural Gas Pipeline Spills

Mid-America Pipeline Company, LLC (MAPCO), and Enterprise Products Operating LLC (Enterprise), of Houston, Texas, have agreed to pay a civil penalty of more than $1 million to the United States to settle violations of the federal Clean Water Act related to three natural gasoline pipeline spills in Iowa, Kansas and Nebraska.

Gulf Coast Vulnerable to Extreme Erosion in Category 1 Hurricanes

Seventy percent of the Gulf of Mexico shoreline is vulnerable to extreme erosion during even the weakest hurricanes, according to a new report by the U.S. Geological Survey released just prior to the start of the 2012 hurricane season.
