New technology developed at the University of Waterloo could make a significant difference in the fight against climate change by affordably converting harmful carbon dioxide (CO2) into fuels and other valuable chemicals on an industrial scale.

Invisible shipping tracks had a clear impact on the properties of clouds they polluted. Surprisingly, the specific effects were different to those of visible shipping tracks.

Tiny amounts of crude oil on the water surface, less than one percent of the thickness of a hair, can damage seabird feathers, a University College Cork (UCC) study finds.

Scientists are ringing alarm bells about a significant new threat to U.S. water quality: as winters warm due to climate change, they are unleashing large amounts of nutrient pollution into lakes, rivers, and streams.

Researchers from Nagoya University in Japan have reported that nitrate accumulated in soil bordering streams plays an important role in the increase of nitrate levels in stream water when it rains.

An analysis of sediments from five North Carolina lakes near coal-burning power plants has found that coal ash pollution of surface waters has been more persistent and widespread than was previously known.

Scientists from the University of Illinois Urbana-Champaign, University of California, Santa Barbara, and Dow have developed a breakthrough process to transform the most widely produced plastic — polyethylene (PE) — into the second-most widely produced plastic, polypropylene (PP), which could reduce greenhouse gas emissions (GHG).

Developing countries should focus on keeping unnecessary occupants, such as children, out of kitchens during cooking to help reduce their exposure to dangerous levels of air pollution, recommends a study by the University of Surrey.   

Oil and gas producers rely on flaring to limit the venting of natural gas from their facilities, but new research led by the University of Michigan shows that in the real world, this practice is far less effective than estimated—releasing five times more methane in the U.S. than previously thought.

In July, purple and pink hues painted the Antarctica and New Zealand skies — likely the result of atmospheric particles called aerosols that belched into the stratosphere in January during the eruption of the Hunga Tonga-Hunga Ha'apai volcano.
