Addition of carbon Combustion is the rapid burning of fossil fuels. Stored carbon in coal‚ oil and natural gas returns to the atmosphere when these fossil fuels are burnt and during natural combustion occurrences such as volcanic eruptions. Fossil Fuels such as coal are constructed when a living organism dies and decomposers‚ ie Fungi and microbes are unable to decompose it. After the organic material is untouched for millions of years‚ it eventually turns into fossil fuels. Petroleum‚ coal and
