Since the industrial revolution began, the atmospheric abundance of key greenhouse gases have increased substantially. As of 2023, the globally averaged atmospheric abundance of carbon dioxide (CO₂) had increased by 151 percent, relative to 1750. Meanwhile, the abundance of methane (CH4) had shot up by more than 260 percent.
Increase in global greenhouse gas abundance in 2023 relative to 1750, by gas
Assuming a pre-industrial mole fraction of 278.3 ppm for CO₂, 729.2 ppb for CH4 and 270.1 ppb for N₂O. The number of stations used for the analyses was 147 for CO₂, 149 for CH4 and 108 for N₂O.
