Coccolithophores, a certain group of algae, form thinner calcite skeletons when the pH value in the ocean drops. In marine ecosystems, changes in the degree of calcification are much more pronounced than presumed to date based on laboratory tests. These changes have an impact on the global carbon balance since the examined microalgae influence the carbon dioxide exchange between ocean and atmosphere.
Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.
The Department of Energy's L Prize challenged the lighting industry to develop high-performance, energy-saving replacements for conventional light bulbs that will save American consumers and businesses money.
More than 150 child car seats, including Graco, Fisher Price, Britax and Evenflo, were tested for hazardous chemicals. See the best and worst list.
This practice of sampling and analyzing tissue from trees and other plants to determine the presence of contaminants in soil and groundwater holds promise because it gives engineers a quick, accurate and inexpensive way to measure the extent of environmental pollutants without having to dig into the ground.
While the popularity of locally and regionally grown food is on the rise among Americans, food accessibility remains a major concern for those with limited financial resources.
New research suggests that nearly half the Earth's heat comes from the radioactive decay of materials beneath the surface, according to a large international research collaboration that includes a Kansas State University physicist.
While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming.
Fallen autumn leaves transfer as much, if not more, hazardous mercury from the atmosphere to the environment as does precipitation each year, according to recent U.S. Geological Survey research.
Researchers found that bacterial microbes inside the slick degraded the oil at a rate five times faster than microbes outside the slick—accounting in large part for the disappearance of the slick some three weeks after Deepwater Horizon's Macondo well was shut off.
Summer is the ideal season for vacations, and whether you plan to spend your days beach bumming, hiking with friends or visiting out-of-town relatives, these tips will help reduce your at-home energy consumption as much as possible while you are away.
The biggest hurdle to widespread implementation of solar power is the fact that the sun doesn't shine constantly in any given place, so backup power systems are needed for nights and cloudy days. But a novel system designed by researchers at MIT could finally overcome that problem, delivering steady power 24/7.
Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction.
Researchers in the Pacific Northwest have developed a new catalyst material that could replace chemicals currently derived from petroleum and be the basis for more environmentally friendly products, including octane-boosting gas and fuel additives, bio-based rubber for tires and a safer solvent for the chemicals industry.
The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately accounted for in most evaluations of prehistoric sea level changes.
The Blue Ribbon Commission on America's Nuclear Future also says currently available revenues are sufficient and a new, non-DOE nuclear waste management program should be established.
The agave plant has not yet been widely cultivated as a fuel source, but it promises some significant advantages over existing sources of ethanol such as sugarcane and corn.
Building on the agreement for model year 2012-2016 vehicles, which will raise fuel efficiency to 35.5 mpg, the next round of standards will require performance equivalent to 54.5 mpg or 163 grams/ mile of CO2 for cars and light-duty trucks by model year 2025.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced that Dow Chemical Company has agreed to pay a $2.5 million civil penalty to settle alleged violations of the Clean Air Act, Clean Water Act and the Resource Conservation and Recovery Act (RCRA) at its chemical manufacturing and research complex in Midland, Mich.
A group of scientists from the University of Alabama are exploring caves in the South Pacific to gain insight on ancient weather patterns.
