Greenhouse gases seen from the perspective of their marginal radiative forcings. This is a nice normalization of how much we should care about each. Note the context in the figure below (found on Mr Smiths Physics at Weebly.com):

Ah! Sankey diagrams!
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.
