However, human activities are now increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural warming caused by the greenhouse effect. During the Industrial Revolution, humans began burning coal, natural gas, and oil to power machines for manufacturing and transportation.
Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere. 87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil.The remainder results from the clearing of forests and other land use changes (9%), as well as some industrial processes such as cement manufacturing (4%).7 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil.
