Air pollution is an existential threat to millions of Americans with asthma and other health issues. 

Using commercial, high-resolution satellite images and artificial intelligence, an international team including NASA scientists mapped almost 10 billion individual trees in Africa’s drylands in order to assess the amount of carbon stored outside of the continent’s dense tropical forests. 

Two banned insecticides known to linger in the atmosphere have been all but eliminated from North America’s Great Lakes region, a study finds.

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.
