Intensive agriculture practices developed during the past century have helped improve food security for many people but have also added to nitrate pollution in surface and groundwaters. New research has looked at water quality measurement over the last 140 years to track this problem in the Thames River basin.
The U.S. Environmental Protection Agency (EPA) recently approved the 8-hour ozone air quality plans for the two California areas with the worst air quality in the nation.
University of Queensland scientists have discovered that an ancient relative of rice contains genes that could potentially save food crops from the devastating effects of global warming.
Fossil fuel combustion, and with it the release of heat-trapping carbon dioxide (CO2), is still growing globally. Beyond climate change, this is also causing the world’s “other CO2 problem,” ocean acidification, i.e., the formation of carbonic acid when CO2 from the atmosphere enters seawater.
Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change.
The burning of sugarcane fields prior to harvest for ethanol production can create air pollution that detracts from the biofuel's overall sustainability, according to research published recently by a team of researchers led by scientists at the University of California, Merced.
Despite having an eight-year head start on Marcellus Shale natural gas extraction, Pennsylvania residents are just as uncertain about the effects of horizontal hydraulic drilling as New Yorkers, researchers at Cornell and Penn State have found.
Lead pipes once used routinely in municipal water distribution systems are a well-recognized source of dangerous lead contamination, but new research from Washington University in St. Louis suggests that the partial replacement of these pipes can make the problem worse.
The U.S. Environmental Protection Agency ordered the Monte Vista Water Company to reduce arsenic levels in their drinking water system or face penalties of up to $37,500 per day for each violation.
The colorful birds of Costa Rica play a crucial role in the country's rural landscapes, by distributing seeds, controlling pesky insects and pollinating plants.
By 2100, global climate change will modify plant communities covering almost half of Earth's land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modeling study.
Rather than releasing carbon dioxide into the air, it can be used to produce methanol – which is an excellent fuel for cars and airplanes – using solar energy. The technology already exists, and a major Nordic research initiative has now been launched that will make the process inexpensive and simple enough to be used on a large scale.
The U.S. Environmental Protection Agency (EPA), the Department of Justice (DOJ), and the State of Illinois announced a Clean Water Act (CWA) settlement with the Metropolitan Water Reclamation District of Greater Chicago (MWRD) to resolve claims that untreated sewer discharges were released into Chicago area waterways during flood and wet weather events.
Avalanches created in controlled laboratory environments are helping us to understand the potentially lethal processes that these natural disasters unleash.
Motorists may be driving on the world's first "green" tires within the next few years, as partnerships between tire companies and biotechnology firms make it possible to produce key raw materials for tires from sugar rather than petroleum or rubber trees.
A newly released study from the Energy Policy Institute at the University of Chicago (EPIC) concludes that small modular reactors may hold the key to the future of U.S. nuclear power generation.
The U.S. Environmental Protection Agency (EPA) has added three hydrocarbons as acceptable alternatives in household and small commercial refrigerators and freezers through EPA’s Significant New Alternatives Policy (SNAP) program.
The Institute of Chemical and Engineering Sciences (ICES), a research institute of The Agency for Science, Technology and Research (A*STAR), and IHI Corporation (IHI) start their collaboration in areas of environmental and energy related technologies.
San Francisco Bay's tidal marshes may face a grave threat from sea level rise in the next century, according to a new study published by a group of scientists, including Professor of Biology Tom Parker.
A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere. The study was published in the Geophysical Research Letters.
