Greenhouse gases are the primary drivers of radiative forcing, as their accumulation in the atmosphere traps energy and increases the Earth's energy imbalance [1]. Measurements confirm that rising levels of these gases directly correlate with current radiative forcing values [2], with the total forcing attributed to greenhouse gases being approximately 2.3 W/m² [3].

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).
measurementRecent measurements indicate that total radiative forcing from all greenhouse gases is approximately 2.3 W/m², indicating that more energy is being trapped by Earth's atmosphere than is being emitted, leading to continuous warming.
measurementCurrent radiative forcing levels are estimated to be around 1.6 W/m², largely driven by rising carbon dioxide and other greenhouse gases.
