Frankly, all I want out of this debate (in the country, not just between Freepers) is an agreement not to cripple the economy without a great deal more human causation evidence

That I can agree with.

together with a much higher level of confidence that global temperatures will continue at the current delta.

Judging from the geological record, staying where we have been at in the last 8kys even is unlikely in the extreme. I would say we can reasonably figure on toggling between deep glacial conditions and moderate temperatures for a few more million years if that is your delta.

I was unclear, I meant the current first derivative with respect to time. It would not have to stay at the current rate for the last 30 years very long to break what have been some historic natural barriers.
