The combustion of fossil fuels (such as coal, oil, and natural gas) releases large amounts of carbon dioxide into the atmosphere, making it the major source of carbon emissions within the past century. Deforestation and forest fires also contribute to carbon emissions but not on the same scale as fossil fuel combustion. Volcanic eruptions release carbon dioxide as well but their contribution is relatively small and sporadic.
