These matters are irrelevant if technologically advanced civilization perishes in nuclear winter.

 

If we accept that there is a net cooling at the surface of the planet from particulate scattering energy, then perhaps we could compensate by cracking oil into methane and venting.  Methane is such an excellent greenhouse gas, we may need it if we experience cooling from dust high in the atmosphere.

 

We might even be able to come up with some first-order estimates on this: how much oil or coal would be needed to compensate, and for how long.
