Aersols are the tiny little particles of matter that are suspened in the air. Most aerosols are naturally occuring through events such as volcano eruptions, dust storms, forest fires and even sea spray. Humans accout for about 10 percent of the aerosols in the air. We put them their mostly by the burning of fossil fuels and the movement of natural surface covers. Scientest aren't really sure if the aerosols are warming or cooling our plant. For the most part they seem to be cooling though. When the aerosol are suspended in the air they are used as a shield for the earth, all the tiny particles reflect the sun's radiation back out into the atmosphere. Plus the aerosols help clouds form by allowing water particles to atach and form clouds which also helps the earth stay cool.
