The four greenhouse gases with the strongest effect on climate through their climate forcing are water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) (I’m omitting halocarbons, which come in a wide variety). We don’t control the concentration of water vapor, temperature does that. But the CO2, CH4, and N2O load is directly due to us.
