I have to agree.

All such arguments seem to pivot on the idea that greenhouse gasses come 
from such natural sources as forest fires and volcanos.  And even mammoth 
farts.  Also, previous climatic eras (ice ages, etc), are supposed to 
indicate that it is a natural process.

Well, if maintainance of global temperature stability is a natural 
process, we can expect variations over time, such that in one era the 
Vikings could farm Greenland, and in another, ice would cover large areas 
of Europe.  But if this is natural, it doesn't mean that the "input" made 
by an incautious mankind -- even if only contributing a small %age to the 
overall -- could not have a deleterious effect.  An artificially induced 
change in ocean pH of 2%, for example, although small, could have far- 
reaching effects.
