The Metropolitan St. Louis Sewer District has agreed to make extensive improvements to its sewer systems and treatment plants to eliminate illegal overflows of untreated raw sewage and to reduce pollution levels in urban rivers and streams.
Over one-third of the world's population already lives in areas struggling to keep up with the demand for fresh water.
Writing in the journal Annals of Botany, Professor Douglas Kell argues that developing crops that produce roots more deeply in the ground could harvest more carbon from the air, and make crops more drought resistant, while dramatically reducing carbon levels.
Residents in the Midwest awoke to the highest mold count for the season after a night of torrential rain and lightening strikes. An official air alert was issued by Joseph Leija, MD, allergist who performs the official allergy count for the Midwest for the National Allergy Bureau.
To date, many academics and government officials have argued that putting a price on carbon – most commonly through taxes or emissions trading – is all that is needed to overcome every possible barrier to delivering cost-effective energy efficiency improvements.
Researchers from the University of Michigan and Ford Motor Co. have assessed the global availability of lithium and compared it to the potential demand from large-scale global use of electric vehicles.
Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, U.S. Geological Survey-led research shows.
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.
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.
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.
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.
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.
