CO2 sources - Biomass burning
In the longer term it can actually contribute to a net carbon sink in the form of relatively stable 'black carbon' in the soils where burning has taken place. Human Impact Though ... some large biomass burning events, the activities of man in the last 100 years have dwarfed carbon dioxide emissions from such natural biomass burning. Huge areas of woodland and grassland are periodically burned ...

Current climate models 'ignoring brown carbon' - SciDev.Net
[BEIJING] Scientists have found that air pollution from East Asia contains an abundance of 'brown carbon' particles and say that atmospheric models need updating to incorporate their effect. Current climate models take ... absorbs light at a negligible level and has no warming effect. It has already been claimed black carbon plays a much larger role in global warming than estimates made by the UN ...
