The position of "sane" climate skeptics appears to be that rising CO2 levels' effects on temperature will be dampened by other regulatory causal effects; the evidence for the existence of such regulatory feedback is the overall stability of climate over long periods of time.

My main concern with that position is that it is whistling in the dark.

That's what I meant with argument about climate models, different models suggest different mixes of positive and negative feedback.

Actually I'd be much more worried about CO2 emissions if I was convinced there was a strong dampening effect of unknown origin. That suggests the system might potentially be stressed to the breaking point, and afterwards a runaway process might result in vesusification. Even a very small risk of that would dominate all other climate related risks.
