The U.S. Environmental Protection Agency (EPA) issued the first Texas Greenhouse Gas (GHG) permit for the Lower Colorado River Authority (LCRA) Thomas C. Ferguson Power Plant in Llano County, Texas.
Coral reefs can both positively and negatively influence the acidity of their surrounding seawater.
NOAA's updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s.
Scientists at the U.S. Department of Agriculture (USDA) are leading the way in learning more about "biochar," the charred biomass created from wood, other plant material, and manure.
The level of the enzyme carbonyl reductase (CBR) is elevated in the livers of fish that have been exposed to cleaned wastewater. Scientists at the University of Gothenburg can show that CBR has properties that may make it suitable to be used as a biomarker, an early warning signal of environmental toxins.
Pipe-in-pipe systems are now commonly used to distribute water in many homes. The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). Are these pipes harmful to health and do they affect the taste and odour of drinking water?
Holm oaks and other forests in lowland areas of Mediterranean mountains could expand by up to 350 percent due to global warming. In contrast, those forest formations that are more adapted to cold and humid conditions, such as beech and Sylvester pines, could shrink by up to 99 percent.
Lake Apopka—Florida's third largest—was once a haven for migratory birds, vacationers and fishermen. Today it is a toxic broth of chemicals and ranks among America's more disturbing Superfund sites.
During the summer 2003, high temperatures and drought conditions in Europe led to a reduction of the wind force with direct consequences on the wind energy power, reduced by 22 percent. The study was recently published in Journal of Climate.
The first complete genus-level dated phylogeny of palms reveals insights into the evolution of rainforests.
Second hand smoke exposure among nonsmokers has declined over time as clean indoor air laws have been adopted. However, there has been concern that such laws might encourage smokers to smoke more in their homes or other private venues.
A team of Virginia Tech researchers is working to characterize the genes involved in wood formation in poplar trees with the goal of improving the quality and quantity of wood as a feedstock for biofuels production.
The U.S. Environmental Protection Agency (EPA) and other federal agencies are teaming up to document and track potential marine debris generated by the Japan earthquake and tsunami in March.
Three of the nation’s leading universities have joined with 15 US companies to launch a first-of-its-kind collaborative research center whose holistic approach to energy efficiency development could mean savings of millions of dollars and a much ‘greener’ electronics industry.
Slow-moving winter weather systems that can lead to massive snowfalls are more frequent during the decades when the North Atlantic Ocean is warmer than usual, a new NASA study finds. The study demonstrates that the impacts of such systems, which are often fueled by an atmospheric phenomenon known as atmospheric blocking, go far beyond the atmosphere and can trigger changes in ocean circulation.
The U.S. Environmental Protection Agency (EPA) has approved the State of Illinois' new and revised water quality standards for five segments of the Chicago and Calumet Rivers.
Whether a species can evolve to survive climate change may depend on the biodiversity of its ecological community, according to a new mathematical model that simulates the effect of climate change on plants and pollinators.
A new study on greenhouse gas emissions from oil palm plantations has calculated a more than 50 percent increase in levels of CO2 emissions than previously thought – and warned that the demand for 'green' biofuels could be costing the earth.
Most of today's power plants--from some of the largest solar arrays to nuclear energy facilities--rely on the boiling and condensing of water to produce energy.
This discovery is a significant breakthrough in the development of sustainable technologies such as dye-sensitized solar cells and organic light-emitting diodes (OLEDs).
