I'm always cautious of the models as you get to the more extreme cases. To me it seems likely that as you get further and further from the current state that there are unknown factors lurking somewhere. Those factors may represent positive feedback, they may be negative feedback, or they may not exist at all. But to me the further into the unknown we go, the further into the unknown we are, if that makes sense. To be absolutely clear, I think the models probably work well enough for the near range. It's the far ranges I wonder about.
