Originally a comment by James Garnett on Triple threat.
I’m not a climate scientist, but my professional work is in control theoretic modeling of real, nonlinear systems. It’s difficult to underscore just how frightening a positive feedback runaway can be; the results are catastrophic for the system in question, even for small things. For example, induction motors form the basis of modern processing engineering, so their function and use are taught in most electrical engineering programs. One aspect of these motors is that when they are running, if one opens the field circuit while the driving circuit is still energized, the torque of the rotor becomes infinite (in theory), because the field acts as a negative feedback control mechanism. … Read the rest
