A NASA satellite instrument that will measure air pollution over North America has reached another key project milestone.

The dynamics that lift smoke from large wildfires into the upper atmosphere could potentially be employed one day to help temporarily cool the planet, based on the findings of a modeling study led by NOAA scientists.

Little is known concerning environmental contaminants in predators at the top of a food chain. A study published in Environmental Toxicology and Chemistry has demonstrated that new types of brominated flame retardants accumulate in the tissues of killer whales near Norway and are also passed on to nursing offspring.

A global effort to reduce sulfur and greenhouse gas (GHG) emissions from ships has researchers from the National Renewable Energy Laboratory (NREL) and other Department of Energy facilities investigating the potential use of marine biofuels.

Researchers at the University of California, Davis, have found a link between traffic-related air pollution and an increased risk for age-related dementia, including Alzheimer’s disease. 

The entire ecosystem of the planet, including humans, depends on clean water. 

Greenhouse gases and aerosol pollution emitted by human activities are responsible for increases in the frequency, intensity and duration of droughts around the world, according to researchers at the University of California, Irvine.

Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study.

The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. 

A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.
