The observations could have important implications for modelling global climate change and predicting air quality conditions. The tiny particles, which form part of an airborne chemical mix above cities, play a role in pollution by providing a surface for chemical reactions and in climate by reflecting and absorbing solar radiation and by acting as seed surfaces for water condensation and cloud formation.
In the years after Columbus' voyage, burning of New World forests and fields diminished significantly -- a phenomenon some have attributed to decimation of native populations by European diseases. But a new University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide.
Bloomberg and TradeWinds News reported July 30 that two judges on India’s Supreme Court have allowed the ship once named the Exxon Valdez to be scrapped at a yard in Alang on the country’s western coast.
Adam M. Fasano, CIH has been promoted to Principal at GZA GeoEnvironmental’s Norwood, MA office. GZA is an environmental and geotechnical consulting firm.
North Carolina’s Waccamaw River watershed will benefit from a $1 million restitution order from a federal court, funding environmental projects to acquire and preserve wetlands in an area damaged by illegal releases of wastewater from a corporate hog farm.
In a new study, University of Pennsylvania biologist Daniel Janzen joins more than 200 colleagues to report that protected areas are still vulnerable to damaging encroachment, and many are suffering from biodiversity loss.
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland -- and reveal a surprising link between the ice and the atmosphere above it.
Today, the U.S. Environmental Protection Agency’s (EPA) Energy Star program launched the 2012 National Building Competition: Battle of the Buildings with a record 3,200 buildings across the country going head to head to improve energy efficiency, lower utility costs and protect health and the environment.
The U.S. Environmental Protection Agency (EPA) has issued complaints seeking civil penalties against three companies for alleged violations of the reporting and recordkeeping requirements under the Toxic Substances Control Act (TSCA).
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland – and reveal a surprising link between the ice and the atmosphere above it.
In a major milestone completing the protection of more than 95 percent of Massachusetts coastal waters from boat-generated sewage pollution, EPA has designated the coastal waters of Nantucket, Vineyard Sounds and the Islands, and Mt. Hope Bay as “No Discharge Areas.”
Sulfur has traditionally been portrayed as a secondary factor in regulating atmospheric oxygen, with most of the heavy lifting done by carbon. However, new findings that appeared this week in Science suggest that sulfur's role may have been underestimated.
Protected ocean areas known as marine reserves jumpstart the recovery of nearby commercial fishing areas after an environmental event, concludes a study of abalone by researchers from Stanford and the Monterey Bay Aquarium.
A chemical producer faces an EPA fine of $93,900 for failing to report the use and storage of hazardous chemicals at its Fairfield, Conn. facility, in violation of the federal right-to-know law.
Inspired by a European study, a team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs.
Climate change, habitat destruction, pollution and invasive species are all involved in the global crisis of amphibian declines and extinctions, researchers suggest in a new analysis, but increasingly these forces are causing actual mortality in the form of infectious disease.
An ice island twice the size of Manhattan has broken off from Greenland's Petermann Glacier, according to researchers at the University of Delaware and the Canadian Ice Service.
The European Commission’s new regulation affecting biocidal products took effect July 17, with authorities there saying the rule means significant benefits for human health and the environment.
Citing recent wildfires in Colorado, Texas, Russia, Greece, and Chile and a report from climate scientists at the University of California, Berkeley and Texas Tech University, a top official at Lloyd’s said insurers face new challenges from wildfires in many parts of the world.
For the first time scientists at ETH Zurich have examined globally the connection between soil moisture and extreme heat with measured data. Their study shows that precipitation deficits increase the probability of hot days in many regions of the world. The results will help to better assess heat risks.
