Despite the limited amount of observations, we must conclude that biomass burning, especially in the tropics where the rates of biomass production and biomass burning are unparalleled, has the potential to contribute in an important way to the global budgets of several major atmospheric trace gases. We also need to consider that tropical emissions occur in a photochemically very active and dynamically important region, in which substantial transfer of tropospheric air to the stratosphere takes place.

According to the global carbon budget by IPCC AR4 report, fossil fuels emission was 7.2 GtonC/y and the atmospheric increase was 4.1 GtonC/y in 2000-2005. The biomass nuclear process removes about 4.9 GtonC/y from atmosphere in the long term, so it will eventually decrease the atmospheric C02 concentration.
