I am amazed at all the hoopla regarding the point of whether or not the increase in green house gasses is man made or not. They are going up. Their increase is linked to global warming. What does it matter if we are the cause or not? The question remains, should we try to stop it and if we do decide to do so how will we do that? There has been some work in this area. One of the more promising approaches:
Southern Ocean Iron Enrichment Experiment (SOIREE)
This experiment was based on a hunch published in 1993 that algae blooms were caused by iron rich desert sand blowing over and landing on the oceans. Several experiments have verified this effect and predictions can be made on the location and size of algae booms based on desert sand storms and jet stream winds. Since algae uses photosynthesis and are net CO2 to O2 producers, large algae blooms can reduce CO2 in the atmosphere. The SOIREE experiment was conducted to asses the feasibility of dispersing iron in ocean areas to see if it would work. It worked.
So the question remains. Do we want to do anything about global warming? Who cares if it manmade or not?
