Scientists for years have argued over drastic action to cool a warming world. Among the most widely debated is stratospheric ...

Scattering microscopic particles of sulfur in the atmosphere might slow down climate change. It might also change weather patterns.

Scientists are seriously considering mimicking volcanic eruptions to mitigate global warming, but that comes with more than a ...

The National Science Foundation (NSF) has renewed a groundbreaking University of California San Diego atmospheric chemistry research program with a $20 million grant that will support operations for a ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 110, No. 51 (December 17, 2013), pp. 20414-20419 (6 pages) The cycling of atmospheric aerosols through clouds can ...

Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions. Rising 2,225 meters into the air on ...

Solid aerosols can change how clouds form in the Arctic. And, as the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from ...

A: Aerosols consist of tiny particles or droplets suspended in the air. Particles are produced by a variety of natural and human sources, ranging from sea salt formed by breaking waves in the ocean, ...

Compounds emitted by trees, diterpenes, could have a previously unconsidered impact on the formation of particles in the ...
