The AR6 of the IPCC said, "It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) since the pre-industrial period are overwhelmingly caused by human activities." Atmospheric methane accounted for 20% of the total radiative forcing (RF) from all of the long-lived and globally mixed greenhouse gases. WebMar 6, 2024 · The mole fraction is expressed as nmol mol -1, abbreviated “ppb” (for parts per billion; 1 ppb indicates that one out of every billion molecules in an air sample is CH 4 ). In the figures, the red lines and circles are globally averaged monthly mean values centered on the middle of each month.
