When I was researching my dissertation in the late 1990s, I wanted to explore the issue of positive feedback (in both political and economic systems), and I wound up using the concept, but the only scientific book I could find on the subject was "Positive feedback in natural systems", Deangelis et al, from 1986.  

It seemed to me then and it seems to me now that most scientific disciplines have been infected with a desire to look at systems that balance and stabilize, and so have concentrated much more on negative feedback systems than on positive ones.  For that reason, I have been assuming that the current climage change models are much too conservative, because I assume that there is a bias against modeling the full consequences of positive feedback looks -- so I'm glad JR is spending time on this crucial issue.

Just another plug for Fred Pierce's book --- all about positive feedback factors that didn't make it into the IPCC reports --- "With Speed and Violence."

Took me a while to do it, because we just got a freak storm in the Chicago area, the O'hare traffic controllers had to evacuate their tower, there were tornado sightings, and the electricity went out for a bit...but hey, at least people can drive SUV's and blow dry their hair!

Name one, and explain exactly how it debunks any part of anthropogenic global warming.
