Atmospheric chemistry: Thwarting the seeds of clouds
Paul J. Ziemann1
Abstract
Atmospheric oxidation of hydrocarbons emitted from plants leads to the formation of aerosol particles that affect cloud properties. Contrary to what was thought, this process might add to global warming.
The ephemeral cloud of tiny drops that you see above the spout of your teapot forms in the same way as clouds in the sky — by the condensation of water vapour onto microscopic 'seed' particles, known as nuclei. In your kitchen, the nuclei are nanometre-sized clusters of tens of water molecules.
