The study included 188 children whose mothers enrolled in Mount Sinai School of Medicine’s New York Children’s Environmental Health Study during their third trimester of pregnancy.
A deadly fish virus that was first discovered in the Northeast in 2005 has been found for the first time in fish from Lake Superior, report Cornell researchers. That means that the virus has now been documented in all of the Great Lakes.
Through effective policy implementation, grazinglands can reduce greenhouse gases through carbon sequestration and emissions reduction offset credits. Carbon sequestration is the long-term storage of carbon in the ground or oceans, slowing the buildup of carbon dioxide in the atmosphere. Carbon dioxide in the atmosphere enters the soil of grazinglands through the natural process of photosynthesis by green plants. The subsequent cycling turns some of that carbon into soil organic carbon—and into an environmental, societal and economic benefit for every country with these grazinglands.
Researchers from NIST and the College of Charleston are at work trying to identify the clues that will finger specific, yet elusive, environmental threats to the Atlantic blue crab.

Civil engineers at the University of Washington and the U.S. Army Corps of Engineers' Seattle office have taken a first look at how dams in the Columbia River basin, the nation's largest hydropower system, could be managed for a different climate.
The simple formula we’ve learned in recent years – forests remove CO2 from the atmosphere; therefore forests help prevent global warming – may not be quite so simple. New Weizmann Institute research shows that forests can directly absorb and retain heat. In at least one type of forest, these effects may cancel out a good part of the benefit in lowered CO2.
With many companies investing heavily in algae-based biofuels, researchers from the University of Virginia's Department of Civil and Environmental Engineering have found there are significant environmental hurdles to overcome before fuel production ramps up. They propose using wastewater as a solution to some of these challenges.
Pioneering University of Maryland ecological economist, Herman Daly, will receive a lifetime achievement award from the National Council for Science and the Environment, recognizing his decades-long research into the underpinnings of a Green Economy. Daly argues that conventional economics fails to account for the true costs of environmental degradation.
The combination of low concentrations of oxygen and nutrients in the lower layers of the beaches of Alaska’s Prince William Sound is slowing the aerobic biodegradation of oil remaining from the 1989 Exxon Valdez spill.
'Greenroads,' released today, assigns points for using sustainable practices in building roads and highways. It aims to do for road construction what the LEED rating system has done for the building industry.
University of Iowa researchers have confirmed that sediments of the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind., are contaminated with polychlorinated biphenyls (PCBs). The IHSC, part of the Calumet River tributary of Lake Michigan, will begin being dredged in the next few years to maintain the proper depth for ship traffic, with uncertain environmental impacts in regard to PCBs.
There may be a strong link between our political affiliation and how we react to certain labels. Democratic, Republican, and Independent volunteers support a mandatory environmental surcharge if it is described as an “offset,” while only Democratic volunteers support the surcharge when it is labeled as a “tax.”
Climate specialist Jeff Gaffney explains Union of Concern Scientists' call for dialogue with American Farm Bureau, which recently said there is no generally agreed scientific assesment on the impact of carbon emissions from human activities.
While governments around the world continue to explore strategies for reducing greenhouse gas emissions, a new study suggests policymakers should focus on what needs to be achieved in the next 40 years in order to keep long-term options viable for avoiding dangerous levels of warming. The study is the first of its kind to use a detailed energy system model to analyze the relationship between mid-century targets and the likelihood of achieving long-term outcomes.

The Climate Change Conference produced a successfully green conference of an enormous magnitude. What can we take away from the UN’s success? The knowledge that if a large scale operation can be green, there is no reason that businesses can’t act similarly on a smaller scale.
Keeping Williams College on course to meet its sustainability goals is central to the work of the college's year-old Zilkha Center for Environmental Initiatives. It takes not only thinking big, but also thinking small. The center is charged with finding ways to incorporate principles of sustainability into campus life and to help the college in reducing its greenhouse gas emissions to 10 percent below 1990-91 levels by 2020.
Sustainability is more than a buzzword within Williams College dining services; it's an imperative. One of the most important ways the college achieves sustainability is by reducing food waste and minimizing resource consumption -- a goal that is written into the department's systems, policies, infrastructure, and building design.
On the front door of the Williams College dining services office -- a small grey clapboard house tucked in the middle of the school's campus in bucolic western Massachusetts -- staffers have placed a bumper sticker that reads "No Farms, No Food." It's a message the college takes to heart. Williams dining services prepares 885,690 meals annually, for its approximately 2000 students, in 4 dining halls, a faculty house, and a number of snack bars.
Which came first, the warmer temperatures or the clearer skies? Answers to that and similar "chicken or egg" type questions could have a significant impact on our understanding of both the climate system and manmade global warming.
