Climate-cooling aerosols can form from tree vapors

Pollution’s sulfuric acid not needed to make cloud-seeding particles in the air

CLOUD MACHINE  Researchers created climate-cooling, cloud-seeding aerosols inside a cloud chamber without the sulfuric acid spewed by fossil fuel burning.

The cooling effect of pollution may have been exaggerated.

Fossil fuel burning spews sulfuric acid into the air, where it can form airborne particles that seed clouds and cool Earth’s climate.
