A key factor in America’s prodigious agricultural output turns out to be something farmers can do little to control: clean air.

Maternal exposure to air pollution during pregnancy has often been linked to adverse effects on the health of the newborn.

Researchers at the National Institute of Standards and Technology (NIST) have upgraded their laser frequency-comb instrument to simultaneously measure three airborne greenhouse gases — nitrous oxide, carbon dioxide and water vapor — plus the major air pollutants ozone and carbon monoxide.

Bioplastics — biodegradable plastics made from biological substances rather than petroleum — can be created in a more economical and environmentally friendly way from the byproducts of corn stubble, grasses and mesquite agricultural production, according to a new study by a Texas A&M AgriLife Research scientist.

Dust storms and other weather phenomena offset some reductions in PM2.5 aerosol pollution.

Scientists are flying an airborne campaign out of NASA's Langley Research Center in Hampton, Virginia this month to contribute to a joint U.S.-Canadian study on air quality in a region with high surface ozone levels.

Scientists from the University of Michigan have developed an innovative way to use NASA satellite data to track the movement of tiny pieces of plastic in the ocean.

Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth’s atmosphere are not equal to the climate changes from deliberate CO2 removals—and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research.

Earth bears many signs of human influence, from warming that exceeds pre-industrial temperatures to a rising sea.

May was arguably the worst month ever for big oil — and the best for its opponents — as courts and corporate shareholders sided with environmental activists to humble the biggest of the fossil-fuel giants, culminating in “Black Wednesday.”
