The large number of tiny organic aerosols floating in the atmosphere -- emitted from tailpipes and trees alike -- share enough common characteristics as a group that scientists can generalize their ...

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

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

It is possible to significantly slow down and even temporarily stop the progression of global warming by increasing the atmospheric aerosol concentration, shows a new study from the University of ...

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

Atmospheric aerosols, consisting of suspended small solid and liquid particles, influence both climate and air quality. Sub-micrometre-sized particles efficiently scatter visible radiation and can act ...

Scientists are taking the once-radical concept of dimming the sun through stratospheric aerosol injection (SAI) seriously, ...

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 ...

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 ...

Tiny airborne particles known as aerosols, from biomass burning, urban pollution, and industrial emissions, can dramatically ...

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

Once considered a fringe idea, the prospect of offsetting global warming by releasing massive quantities of ...
