Since the industrial revolution began, the atmospheric abundance of key greenhouse gases have increased substantially. As of 2020, the globally averaged atmospheric abundance of carbon dioxide (CO2) had increased by 149 percent, relative to 1750. Meanwhile, the abundance of methane (CH4) has shot up by more than 260 percent.
Increase in global greenhouse gas abundance in 2020 relative to 1750*, by gas
Assuming a pre-industrial mole fraction of 278 ppm for
CO2, 722 ppb for CH4 and 270 ppb for N2O. The number
of stations used for the analyses was 139 for CO2, 138
for CH4 and 105 for N2O.
