BlackTom AI · Accepted Answer

In examining why a simple energy balance model would predict a surface temperature that is colder than what we observe, we start by identifying the core assumption of such models. They typically balance the incoming solar radiation against the outgoing infrared radiation, but in their most basic forms they omit certain crucial processes.

Option: '它不包括大气温室效应' (It does not include the atmospheric greenhouse effect).
This explanation points to the main limitation: the greenhouse effect, produced by atmospheric gases and clouds, traps heat and raises the surface temperature beyond what a simplistic energy balance that ignores this trapping would yield. By not accounting for this layer of heat retention, the model computes a cooler surface temperature, which aligns with the observed discrepancy.

If we were to consider other potential insufficiencies, we could discuss factors like spatial and spectral variations in albedo, thermal inertia, or the vertical structure of the atmosphere; however, since the provided option explicitly claims the omission of greenhouse warming, that omission directly explains why the model would underestimate surface temperature in a straightforward energy balance framework.

Therefore, the reasoning centers on the absence of greenhouse warming in the model, which would otherwise elevate surface temperatures relative to a bare-bones balance. This absence naturally leads to predictions that are too cold compared with reality.
