What happens to the energy that corresponds to the absorbed radiation?
Since energy cannot be created or destroyed (leaving relativistic
effects aside here), do the lowest few tens of meters continue to heat
indefinitely?

Where does the OLR come from, if (as you state) all the outgoing
radiation from the surface is absorbed in the lowest few tens of meters?
