Which numerical models? The ones for predicting climate into the near future?

There is a strong scientific consensus that climate is strongly influenced by greenhouse gas concentrations. I am guessing you didn't mean to say that it is possible that there is "no force or process is causing climate to vary" so I'll just ignore that.

Look I agree with most of what you're saying, but you're saying there's a lack of evidence on my side. But then where's the evidence for what you're saying? What evidence is there that the milankovich cycle is able to produce the magnitude of oscillations in temperature that we're seeing?
