While methane (CH4) and nitrous oxide (N2O) have higher global warming potentials per molecule than CO2, the much larger increase in CO2 concentration in the atmosphere results in its dominant contribution to the overall anthropogenic radiative forcing. Ozone (O3) also contributes, but its distribution and lifetime are more variable.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which one of the following greenhouse gases is the largest single contributor to anthropogenic radiative forcing?
