Fossil fuels, even when burned perfectly (natural gas, or methane, burns the best) release carbon dioxide which is a greenhouse gas causing dangerous global warming. Most fossil fuels also release smoke (leading to smog), and they may also release sulfur oxides and nitrogen oxides which contribute to acid rain.  The burning of fossil fuels (coal, oil and natural gas) in  industry, transport and the generation of electricity releases  carbon dioxide (CO2) which is cau â¦ sing global warming.
The man-made (or anthropogenic) component of the greenhouse effect is caused by manâs activities that emit greenhouse gases to the atmosphere. The most important of these is the burning of fossil fuels. Fossil fuels contain carbon, and when they are burnt this carbon combines with oxygen in the atmosphere to form carbon dioxide. Changes in land use are also important sources of greenhouse gas emissions.
