Future Atmospheric CO2 Concentration Trends

The future rate of change of CO2 depends significantly on future rates of industrial CO2 emissions, and therefore, on future energy development. Land use practices also will play a role. If fossil fuel energy consumption in the next 20 years 

Predictions of atmospheric CO2 change depend not only on choices concerning future energy sources but also on the rate of world population growth, and the ultimate maximum energy consumption per capita. These estimates are difficult to make, but various scenarios have been developed to provide some limits on future CO2 concentrations.
