It’s an idea straight out of science fiction – 'blocking the sun' to cool the atmosphere and curb or even reverse climate change. But research has shown that the hugely controversial idea of solar ...

New insights into the behavior of aerosols from cooking emissions and sea spray reveal that particles may take up more water than previously thought, potentially changing how long the particles remain ...

Kimberly Prather, an atmospheric chemist at UC San Diego, is one of 20 scientists being honored by the National Academy of Sciences for extraordinary achievements, it was announced Monday. Prather was ...

The World Meteorological Organization’s fifth annual Air Quality and Climate Bulletin, issued in September, called attention to the effects of air pollution on climate change and human and ecosystem ...

A controversial plan to cool the planet by spraying aerosols into the stratosphere is not as dangerous as it has been portrayed, scientists have argued. The idea of ‘solar geoengineering’ or solar ...

A collaborative research team has introduced a nitrogen-centric framework that explains the light-absorbing effects of atmospheric organic aerosols. This groundbreaking study reveals that ...

Atmospheric aerosols—suspended particles ranging from a few nanometres to tens of micrometres in diameter—play a pivotal role in air quality, human health and the Earth’s radiative balance. These ...

The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and ...

A plant can’t flee when a hungry animal chomps down on its leaves, stem, or roots. It can, however, release a cloud of volatile organic compounds (VOCs) to dissuade predation and cry out to its ...

Twenty years ago, Brent Holben was part of a NASA team studying vegetation from space. In an unlikely career twist, his research morphed into the study of a critical, if overlooked, subplot in the ...
