Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different. Historical comparisons.

The “for one year” part is crucial: stratospheric aerosols stay in the atmosphere roughly a year, so one gram offsets the heating effect of one ton only for the first year after the ton is emitted.
