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.
It is caused by humans burning fossil fuel (coal, oil and natural gas) and cutting down forests. Both of these mean more carbon dioxide in the greenhouse gases in the atmosphe â¦ re. The extra carbon dioxide is causing global warming, which is causing climate change.his is caused by an increase in atmospheric carbon dioxide levels, resulting principally from our use of fossil fuels such as coal, oil and natural gas, and from the manufacture of cement and deforestation.
