EPA Urged To Limit CO2 Pollution From Cargo And Cruise Ships
October 3, 2007 12:04 PM -

Washington, D.C., - A US supreme court decision has cleared the way for the Environmental Protection AGency to order shipping companies to lower the pollution caused by ships.

Today a coalition of environmental advocates filed a petition today with the U.S. Environmental Protection Agency (EPA), asking the agency to set pollution rules for large, ocean-going marine vessels. These vessels include cargo and cruise ships. Earthjustice, the leading U.S. public interest environmental law firm, filed this first ever petition on behalf of Oceana, Friends of the Earth and the Center for Biological Diversity.

California Attorney General Edmund G. “Jerry” Brown, Jr. also filed a petition to U.S. EPA Administrator Stephen L. Johnson on behalf of the state of California today, with a similar request.

The petitions would require the EPA to assess ships’ contributions to global warming, seek public comment and issue rules to reduce this pollution or explain why it will not act. 

New method could advance development of hydrogen-fueled cars
October 2, 2007 09:29 PM - UCLA News

Los Angeles, California - Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a model that could help engineers and scientists speed up the development of hydrogen-fueled vehicles by identifying promising hydrogen-storage materials and predicting favored thermodynamic chemical reactions through which hydrogen can be reversibly stored and extracted.

The new method, published online in the peer-reviewed journal Advanced Materials, was developed by Alireza Akbarzadeh, a UCLA postdoctoral researcher in the department of materials science and engineering; Vidvuds Ozolins, UCLA associate professor of materials science and engineering; and Christopher Wolverton, professor of materials science and engineering at Northwestern University in Illinois.

Obama would seek nuclear ban if elected
October 2, 2007 08:28 PM - Andrew Stern

CHICAGO (Reuters) - Democratic presidential candidate Barack Obama said on Tuesday if elected president he would pursue a global ban on nuclear weapons as he sought to pick up ground on his front-running rival, Hillary Clinton.

"Here's what I'll say as president: America seeks a world in which there are no nuclear weapons," Obama said.

Obama marked the five-year anniversary of a speech he gave as a U.S. Senate candidate outlining his opposition to the Iraq war, noting it came just 10 days before his top rival for the party nomination, New York Sen. Clinton, voted to back the invasion of Iraq.

"Let's be clear: without that vote, there would be no war," Obama told DePaul University students. "This is not just a matter of debating the past. It's about who has the best judgment to make the critical decisions of the future."

Going Beyond Formaldehyde Binders in Manufactured Wood Products
October 2, 2007 01:20 PM - , BuildingGreen

Manufactured wood products—including plywood, oriented-strand board (OSB), laminated-strand lumber, particleboard, and medium-density fiberboard (MDF)—have the environmental advantage of being made from small-diameter or other low-quality trees or waste from wood-processing operations, conserving higher-quality timber.

With these products, the wood is peeled into thin veneers, chipped into small strands or flakes, or ground into wood flour; in each case, the pieces are then glued to produce a durable and stable panel or lumber product. Two glues, or binders as they are called in the industry, dominate the manufactured wood products industry: urea formaldehyde (UF) and phenol formaldehyde (PF).

Ancient Fossils Points to Carbon Dioxide As a Driver of Global Warming
October 2, 2007 12:37 PM -

PASADENA, Calif.--A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.

In the current issue of the journal Nature, geologists and environmental scientists from the California Institute of Technology, the University of Ottawa, the Memorial University of Newfoundland, Brock University, and the Waquoit Bay National Estuarine Research Reserve report the results of a new method for determining the growth temperatures of carbonate fossils such as shells and corals. This method looks at the percentage of rare isotopes of oxygen and carbon that bond with each other rather than being randomly distributed through their mineral lattices.

 

USDA seeks help from consumers after beef recall
October 1, 2007 05:44 PM - Reuters

WASHINGTON (Reuters) - The U.S. Agriculture Department on Monday said consumers play a major role in avoiding any of the 21.7 million pounds of ground beef, at risk for the E. coli bacteria, flagged in the fifth-largest meat recall in U.S. history.

The recall by Topps Meat Company LLC has generated reports of 27 illnesses suspected to be linked to the recalled meat, USDA said, but just three have been confirmed.

The department suspended the raw processed meat operations of Topps on September 26 after an initial recall of 331,582 pounds of frozen ground beef products.

"This is frozen product" and could still be in home freezers, said Richard Raymond, the Agriculture Department's undersecretary for food safety. He added that "consumers have a big role" in getting the meat out of circulation.

Air Fresheners Unregulated, Potentially Dangerous, Group Says
October 1, 2007 10:45 AM - Alana Herro, Worldwatch Institute

A study of 14 common household air fresheners has found that most of the surveyed products contain chemicals that can aggravate asthma and affect reproductive development, according to the Natural Resources Defense Council (NRDC). “There are too many products on the shelves that we assume are safe, but have never even been tested,” said Dr. Gina Solomon, NRDC senior scientist. “The government should be keeping a watchful eye on these household items and the manufacturers who produce them.”

Turning Your Office Wasteland Into A Recycling Haven
October 1, 2007 10:29 AM - , Environmental Graffiti

For several years, colleagues within our office looked around at the mountains of used printer paper, newspapers and other waste that surrounded them and made mild mutterings about how awful it was that it all just went into the main waste skip and wasn’t recycled. Yet while many were keen to see the waste dealt with in a better way, no-one was particularly keen to take on the recycling role themselve  Yet, when we finally got the bit between our teeth at the start of the year and decided once and for all that the waste must stop, it turned out to be much easier than anticipated.

Cost of Coal
October 1, 2007 09:55 AM - Reuters

AYFORD MOUNTAIN, W. Va - Larry Gibson's tiny house sits in a green oasis on top of the Appalachian peak his family has called home for 230 years. The setting would be peaceful if not for the roar of machinery scraping away the surrounding mountain in search of coal  "It's a noisy, dusty place. They dynamite constantly," said Gibson, 61. "It's the genocide of Appalachia, the destruction of a people who have lived in these mountains forever.  Gibson has emblazoned the wooden cabin he calls home with a banner calling for an end to mountaintop mining, along with the words "We are the keepers of the mountains ... don't destroy them" -- his defiant stand against coal companies who have offered to buy his land.
