Roughly half the aerosols that affect air quality and climate change in North America may be coming from other continents.
A new analysis of complex interactions between humans and the environment preceding the 9th century collapse and abandonment of the Central Maya Lowlands in the Yucatán Peninsula points to a series of events -- some natural, like climate change; some human-made, including large-scale landscape alterations and shifts in trade routes -- that have lessons for contemporary decision-makers and sustainability scientists.
Invasive species -- plants, animals, and microbes introduced to regions beyond their native range -- carry a global price tag of $1.4 trillion dollars. They are responsible for the loss of natural resources and biodiversity, damages to infrastructure, and an uptick in infectious diseases.
In settlement papers filed in federal district court, three companies have agreed to pay about $29.8 million in cleanup costs for a Superfund site in Fairmont, Marion County, W. Va., the U.S. Environmental Protection Agency (EPA) has announced.
The Department of Justice and the U.S. Environmental Protection Agency have announced a settlement with two subsidiaries of Sinclair Oil Corporation to resolve alleged violations of air pollution limits established in a 2008 consent decree at refineries in Casper and Sinclair, Wyo.
The report card provides information about the current and predicted-future state of Australia's marine climate and its impact on our marine biodiversity. The report card also outlines actions that are underway to help our marine ecosystems adapt to climate change.
Engineers at a company co-founded by a University of Texas at Dallas professor have identified a material that can reduce the pollution produced by vehicles that run on diesel fuel.
A new carbon cycling model developed at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory better accounts for the carbon dioxide-releasing activity of microbes in the ground, improving scientists' understanding of the role soil will play in future climate change.
A shipping company headquartered in Italy and the chief engineer of one of its ships were sentenced today in federal court in Mobile, Ala., for deliberately falsifying records to conceal discharges of oily wastewater from the ship directly into the sea.
Ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta document the region's ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt's Old Kingdom, the era known as the pyramid-building time.
The mayor of Dallas, Texas, Mike Rawlings, signed a proclamation Aug. 15 declaring a local state of disaster to be in effect for seven days as officials in the city and Dallas County respond to a widespread outbreak of West Nile Virus.
A new study led by scientists at the University of York has shown how birds, butterflies, other insects and spiders have colonised nature reserves and areas protected for wildlife, as they move north in response to climate change and other environmental changes.
An analysis of a decade's worth of tropical cyclones shows that when hurricanes blow over ocean regions swamped by fresh water, the conditions can unexpectedly intensify the storm.
A freshwater snail declared extinct in 2000 was recently rediscovered in the Cahaba River by a University of Alabama graduate student.
This year's Atlantic hurricane season got off to a busy start, with 6 named storms to date, and may have a busy second half, according to the updated hurricane season outlook issued Aug. 9, 2012 by NOAA's Climate Prediction Center, a division of the National Weather Service.
According to the United Nations' 2011 Revision of World Urbanization Prospects, global urban population is expected to gain more than 2.5 billion new inhabitants through 2050.
After studying a decade’s worth of satellite images, a team of researchers found what appears to be a correlation between El Niño events and increased deaths due to the pollutants in smoke from fires.
In California's Los Angeles Basin, levels of some vehicle-related air pollutants have decreased by about 98 percent since the 1960s, even as area residents now burn three times as much gasoline and diesel fuel.
Pine trees are one of the biggest contributors to air pollution. They give off gases that react with airborne chemicals -- many of which are produced by human activity -- creating tiny, invisible particles that muddy the air.
Researchers from the University of Pennsylvania, along with collaborators from Italy and Spain, have created a material that catalyzes the burning of methane 30 times better than do currently available catalysts.
