Recent observations from satellites have shown that the smoke from Arctic wildfires is drifting over the Greenland ice sheet, settling on the ice as soot and making it more likely to melt under the sun.
According to researchers, coastal fog in California contains elevated mercury levels, which may be the result of upwelling deep ocean water along the coasts. Upwelling processes bring mercury to the surface of the water, where it enters the atmosphere and is absorbed by fog.
In a new study, researchers have found an association between fine particulate matter reductions and improved life expectancy in 545 counties across the U.S.
With a new method for estimating greenhouse gases, researchers have found that the levels of nitrous oxide, a potent greenhouse gas, are much higher than previous predictions.
The symbiotic relationship between airborne particles and pollutants demonstrate how city pollution ends up in faraway places such as the Arctic.
According to new research from universities in Sweden, drained wetlands are capable of producing as much greenhouse gas emissions as Swedish industry.
According to a new study, Boston has more than 3,000 leaks from aging natural-gas piping systems across the city.
Children in eight Ohio school districts will benefit from Ohio EPA grants awarded to install pollution control equipment on 75 buses and idle reduction technology on 68 buses as part of Ohio EPA’s Clean Diesel School Bus Grant program.
The contest attracted a record number of entries in 10 categories ranging from Air Quality and Climate to Wastewater.
Researchers have presented an extensive analysis of the role of nanomaterials in environmental remediation and monitoring, which can be used to clean up toxins and bacteria from natural waters, wastewaters, and the air.
First Wind, an independent U.S.-based wind energy company, announced that construction of its 34 megawatt (MW) Bull Hill Wind project has been completed and commercial operations have begun.
According to research from the University of Gothenburg, Sweden, emissions of fossil carbon and the resulting increase in temperature could prevent the earth from having a future ice age.
Schneider Electric’s Conserve My Planet Program helps students, faculty and staff cut energy costs by $73,000 in the Allen Independent School District.
The 73-foot Spruce Christmas tree that will be decorated outside the U.S. Capitol building this holiday season has begun its 24-day journey from Colorado to Washington, D.C. The Mack truck transporting the tree has near zero emissions due to its clean diesel engine.
The National Center for Atmospheric Research is launching a three-year, international study to determine the impact open-fire cooking has on regional air quality and disease.
The USDA has patented a process to capture and recycle ammonia from livestock waste, which could help farmers reduce harmful emissions and concentrate nitrogen into a liquid to sell as fertilizer.
Since 2005, The Schneider Energy Action program has decreased CO2 emissions in commercial and industrial sites by 15% and hopes to further reduce emissions by 10% or more by 2014.
According to a report from the IEA, hydroelectricity production could be doubled by 2050 – preventing up to 3 billion tons of CO2 emissions from fossil fuel plants each year.
Study by scientists has found that burning all the Earth’s reserves of fossil fuels could cause sea levels to rise by as much as five meters – with levels continuing to rise for typically 500 years after carbon dioxide emissions ceased.
A research team led by the University of Texas at Austin is conducting a major field study to measure the methane emissions produced from natural gas production. The study is expected to be completed by Jan. 13, 2013.
