A new study from Tulane University which compared popular diets on both nutritional quality and environmental impact found that the keto and paleo diets, as eaten by American adults, scored among the lowest on overall nutrition quality and were among the highest on carbon emissions.

New research led by Scripps Institution of Oceanography at UC San Diego has confirmed that coastal water pollution transfers to the atmosphere in sea spray aerosol, which can reach people beyond just beachgoers, surfers, and swimmers.

Municipal wastewater treatment plants emit nearly double the amount of methane into the atmosphere than scientists previously believed, according to new research from Princeton University. 

Images of vast clouds of wildfire smoke towering into the sky have become all too familiar during the recent years of record-breaking fires across the western United States and elsewhere.

In the last decade, growing numbers of researchers have studied plastic pollution, one of the world’s most pressing environmental hazards.

Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new UC Riverside research.

An improved global understanding of river temperature could provide an important barometer for climate change and other human activities.

An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can’t.

Led by scientists at The University of Manchester, a series of new stable, porous materials that capture and separate benzene have been developed.

New estimates by Melbourne Climate Futures researchers shows that health impacts from vehicle emissions are likely to be far higher than previous figures informing policy decisions, as a broad group of air pollution experts call for urgent action to clear the air.
