Carbon dioxide is identified as the primary greenhouse gas driving radiative forcing, contributing approximately 64% of the total effect from long-lived greenhouse gases [1]. Furthermore, both concepts are used as the defining metrics for the planetary boundary for climate change [2], with CO2 alone accounting for an estimated 1.68 W/m² of radiative forcing [3].

claimThe planetary boundary for climate change is defined by two key factors: atmospheric carbon dioxide (CO2) concentrations and radiative forcing.
measurementNASA estimates that the current radiative forcing from CO2 alone is approximately 1.68 W/m².
claimNASA and the National Oceanic and Atmospheric Administration (NOAA) report that radiative forcing has increased significantly over the last century due to the accumulation of greenhouse gases, primarily CO2, methane (CH4), and nitrous oxide (N2O).
measurementCurrent radiative forcing levels are estimated to be around 1.6 W/m², largely driven by rising carbon dioxide and other greenhouse gases.

measurementApproximately 64% of the radiative forcing resulting from long-lived greenhouse gases is attributed to CO2, making it the primary anthropogenic greenhouse gas.
measurementCO2, CH4, N2O, dichlorodifluoromethane (CFC-12), and trichlorofluoromethane (CFC-11) collectively contribute to approximately 96% of the radiative forcing attributed to long-lived greenhouse gases.
