Aerosols are fine airborne particles. The main sources of
aerosols in the atmosphere would be industrial pollution ( sulfate, nitrate,
ammonium, organic carbon, elemental carbon ), wind-blown dust ( mineral dust), the ocean ( sea salt), and volcanic eruptions
( soot). Aerosols have a few impacts on
the climate changes. Certain aerosols themselves
can reflect or absorb sunlight. Sea salt particles reflect sunlight back out
into space. Black carbon particles from burning of wood or fossil fuels absorb
most of the sunlight that hits them. Aerosols also help clouds form. The
millions of little droplets of water that make up a cloud each need a little
particle, like an aerosol, to condense upon. More aerosols can create more
clouds. Clouds reflect incoming solar radiation back out to space. Aerosols are
also harmful to our health. The most obvious harm to us would be in respiratory
problem since they are in the air we breathe every day. This is the main reason
we are trying to get rid of aerosol contributing sources. Getting rid of
aerosols helps our health, but accelerates the rate of global warming.
