Leaner, greener flying machines for the year 2025 are on the drawing boards of three industry teams under contract to the NASA Aeronautics Research Mission Directorate's Environmentally Responsible Aviation Project.
A new study comparing the carbon-holding power of freshwater wetlands has produced measurements suggesting that wetlands in temperate regions are more valuable as carbon sinks than current policies imply, according to researchers.
Innovative financing and pricing flexibility are key to preparing the nation’s aging freshwater systems to handle growing demand and environmental challenges, according to a Charting New Waters report recently released by The Johnson Foundation at Wingspread, American Rivers and Ceres.
Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). While these are the most common solar events, the sun can also emit streams of very fast protons -- known as solar energetic particle (SEP) events -- and disturbances in the solar wind known as corotating interaction regions (CIRs).
Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis.
The effects of burning on rangelands have long been debated. Although it is desirable to remove woody plants and invasive species, fire may also eliminate the native grasses that are important for raising cattle. Studying the effects of burning over a span of years can inform land managers how rangelands will respond to this type of management.
Oregon Potato Company failed to report an anhydrous ammonia release at their facility in Warden, Wash., and will pay the U.S. Environmental Protection Agency (EPA) a $66,235 penalty.
Over dinner on R.V. Calypso while anchored on the lee side of Glover's Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan—a young ocean ecologist who had worked in the lush coral reefs of the Caribbean and Sinai Peninsula—found this difficult to believe. It was December 1974.
A research team led by University of Massachusetts Amherst resource economist Sylvia Brandt, with colleagues in California and Switzerland, have revised the cost burden sharply upward for childhood asthma and for the first time include the number of cases attributable to air pollution, in a study released in the online version of the European Respiratory Journal.
The solar array is the first-ever installed on the office building and ReStore location for any Habitat for Humanity affiliate in the United States.
A team at the Polytechnic University of Cartagena has designed a new method for calculating drought trends. Initial results suggest that by the year 2050 there could be a 15 percent increase compared to the droughts seen in 1990 in the Segura river basin.
A new report from the Environmental Change Institute at Oxford University outlines its strategy to transform the U.K.’s built environment.
A 23-year study of dry sclerophyll forests in south-eastern NSW has thrown new light on the role of fire in the landscape.
The Environmental Protection Agency (EPA) has issued an order to halt discharges of animal waste, industrial run-off and other pollutants into the Rio Grande. The action was taken against the Downs at Albuquerque Inc. and EXPO New Mexico, a 93-acre race track and casino in Albuquerque, New Mexico, that accommodates almost 1,400 horses during racing season.
Changes of seasonal cycles are important to social and economic activities, agricultural planning in particular. Quantified changes in the timings of 24 seasonal divisions conventionally known in China as the "24 Solar Terms," based on a recently developed homogenized dataset of daily temperature observations dating to 1960. The results provide quantitative guidance for adaptation to global warming in the
The U.S. Environmental Protection Agency (EPA) recently announced that current and former owners and operators of the Occidental Chemical Corporation Superfund Site in Lower Pottsgrove Township, Montgomery County, Pa. have agreed to pay $2.1 million in past cleanup costs for the site.
Expansion of one of the world's most important shipping routes brings with it a unique opportunity to reduce the carbon footprint of the marine industry, experts claim.
Research conducted by the team at the Integrated Field Research Challenge (IFRC) site in Rifle, Colo. has shown that indigenous bacteria can be stimulated to immobilize the uranium, resulting in groundwater concentrations below the U.S. Environmental Protection Agency standard.
The research assesses the benefits of white roofs and aims to help residential, commercial and industrial building owners determine if white roofs are suitable for their buildings and guide them through the best materials to use.
Here are relatively simple and inexpensive best management practices that can minimize or eliminate environmental risks associated with runoff from rainfall and snowmelt.
