Algae have been researched as a useful, natural possible solution to global warming. There are many different types of algae that produce DMS in different qualities. Most of the planetary radiation is absorbed through water vapor, carbon dioxide and ozone. The amount of water vapor in the atmosphere in any given region over the globe will depend on how much infra-red absorption will occur. Natural aerosols are usually more abundant than man-made, except in highly industrialized regions.
Aerosols are small-suspended particles that scatter and absorb solar radiation.
The scattering of solar radiation increases the path length of a proton through the atmosphere. In response to this, aerosols indirectly increase the probability of absorption. Sulfite is a vital biochemical element that is found in our atmosphere as well. Its primary sources are from volcanic emissions, sulphur in microorganisms and sea salt returning to the geosphere through sedimentation. Algae transfer between 20 and 50 million tonnes of sulphur from the oceans to the atmosphere each year, while human activity only accounts for 80 tonnes.
