Positive / self-reinforcing feedback loop

A feedback loop where effects amplify themselves – crisis in one system worsens another, which worsens the first. A vicious cycle.

Details

Our Take
Confusing because 'positive' sounds good; in systems science it means amplifying (which can be good or bad). 'Self-reinforcing' or 'vicious cycle' avoids the confusion. Central to the polycrisis concept. The key loops: the doom loop (climate-fiscal), the derailment spiral (climate-political), and on the positive side, hope spirals.
