Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. 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.
