Anthropogenic aerosols damage the climate
An aerosol spray produces a gaseous cloud of solid particles. Aerosols are now available containing a wide range of products, such as deodorant, polish, cleaning agents, etc.
In the past aerosols also contained chemical propellants that harmed the ozone layer, these are now banned. These gases either:
- reflected sunlight back into space which had a cooling effect on the atmosphere
- or they absorbed more of the the energy in sunlight which had a warming effect on the atmosphere
Aerosol particle size are approximately 0.001 to 10 microns in size, and these smaller particles remain in the atmosphere for a long time and have a disproportionate effect on the temperature of the atmosphere.
