The largest human impact on the carbon cycle is through direct emissions from burning fossil fuels, which transfers carbon from the geosphere into the atmosphere. The rest of this increase is caused mostly by changes in land-use, particularly deforestation.
When the carbon in  the fuel is burnt with oxygen from the atmosphere, the energy that  was used in photosynthesis is released and carbon dioxide is  re-formed.    Coal, oil, and natural gas are fossil fuel. When they are used they  are gone forever. They are called non-renewable.ossil fuel combustion results in the emission of carbon dioxide,  which is a heat trapping greenhouse gas.    Volcanic activity releases some hundred million tons o â¦ f CO2 into  the atmosphere each year.
