The Relation between the CO2Concentration Levels and the Temperature

Abstract

Carbon dioxide can change the heat balance of the atmosphere. To study the relationship between CO2 and temperature change, we use the given CO2 concentrations to implement linear regression model, gray time series forecasting model, back-propagation model, and auto-regressive and moving average model to establish the growth function of CO2 concentration. Errors are evaluated to choose the most suitable model.Then we use the most suitable model in step one to further predict future land-ocean temperature. Finally, we use grey relational analysis to analyze the relationship between CO2 concentrations and land-ocean temperatures since 1959.
