Volcanoes draw plenty of attention when they erupt. But new research led by the University of Washington shows that volcanoes leak a surprisingly high amount of their atmosphere- and climate-changing gases in their quiet ...
Secondary organic aerosol (SOA) consists of extremely small particles generated in the atmosphere from natural and human-made emissions. It is a major constituent of PM2.5 (particulate matter with a diameter smaller than ...
In addition to oxygen, nitrogen or carbon dioxide, the air we breathe contains small amounts of organic gases, such as benzene and toluene. These oxidize into small particles or aerosols that contribute to the condensation ...
Aerosols are tiny particles that can have a significant impact on Earth's climate and human health.
Scientists have shed new light on the "self-cleaning" capacity of the atmosphere.
A new study shows that global atmospheric dust—microscopic airborne particles from desert dust storms—has a slight overall cooling effect on the planet that has hidden the full amount of warming caused by greenhouse gases.
One year ago, the Hunga Tonga-Hunga Ha'apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga, spewing volcanic material up to 58 km into the atmosphere. It brought a nearly 15 m tsunami ...
The favored refrain of climate deniers and those who oppose climate policies is that "the science is not settled." To some degree, this is true. Climate scientists are still uncertain about a number of phenomena. But it is ...
Black carbon aerosol is the product of incomplete combustion of fossil fuels and biomass, and has strong light absorption. Black carbon deposition in snow ice reduces the albedo of the snow ice surface, accelerating the melting ...
Human activity is changing atmospheric chemistry—even in remote places—that could alter how and when clouds form.
