why is it impossible to infer the surface temperature of Venus by spectroscopy observation from earth？
The important difference is that the word "surface" has a different meaning depending on whether we're talking about the Sun or Venus.
When we say "the surface of the Sun," we ...

The consequences and the mechanisms of a shift of the Earth away from the sun

why is it impossible to infer the surface temperature of Venus by spectroscopy observation from earth？
I think the problem is that spectroscopy at visible and infrared wavelengths simply can't penetrate the thick atmosphere of Venus. Thus the information comes from much higher in the atmosphere and not ...

Is there a formula for calculating surface temperature of a rocky world based on atmosphere and solar input?
Guillot et al. 2010 give a comparatively simple solution (their Eqn. 27) for a double-gray purely radiative atmosphere. It reproduces the equilibrium temperature in the optically thin limit.
