My reservations about the present models is that the information is necessarily not complete, owing to the lack of complete historical records before a certain point. Plus the ones I've heard about (no direct knowledge here) seem to start their trends from the end of the last mini ice-age that was induced by (I
think) Krakatoa's eruption, which seems to me might just skew things a bit, and I've yet to hear anyone claiming to have compensated for that -- but again, it's not my area at all.
I suppose if things get too warm, we could just get a really big volcanic eruption to settle them down.
