You mean the reality is more complicated than cogitator's claim that "most of the feedback loops are positive?" I agree, it is much more complicated.
For my own part I'm not too worried about it. Within this century we'll have the technical ability to feasibly control the Earth's energy budget.
I do think it's complicated, but I'd also agree with him that it's looking like the near term cycles that we need to worry about are positive feedbacks.
Loss of Ice and Snow = darker surfaces = more warming = more loss of ice and snow
Thawed tundra = release of stored methane = more warming = more thawing tundra
Hotter temperatures = more forest fires = release of carbon = hotter temperatures
etc.
As for controlling the energy budget, now that would really be something. But, given that we can't even balance our national budget, I don't know if we should hold our breath on that one :{)
