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.

By Phil McKenna Climate policies that rely on decarbonization alone are not enough to hold atmospheric warming below 2 degrees Celsius and, rather than curbing climate change, would fuel additional warming in the near term, a study published Monday in the Proceedings of the National Academy of Sciences concludes.

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.
