When coal is burned due to combustion that is more or less completed the result is different levels of energy (B.T.U.'s), and different levels of air emissions (Sulfur Dioxide - SO2, Mercury - Hg), greenhouse gases (Carbon Dioxide CO2, Nitrogen Oxide - NO3), and amounts of ash that can potentially be toxic dependent on the conditions within the combustion chamber and ash that can or can not be used in a secondary market (ex.
Scientists say it's apparent that human activity — namely burning coal, oil and natural gas — has been driving a rapid rise of carbon dioxide levels in the atmosphere.
The problem is that we have got enough coal to burn for several hundred years, even with a growing world population with higher aspirations, and if we convert all of that coal, and therefore burn it, without capturing the carbon dioxide we would probably be able to raise the carbon dioxide level ultimately to around 1,500 parts per million.
