“We still understand remarkably little of the mechanisms that determine major transitions in societies, or that regulate the stability and resilience of the climate and ecosystems.
It is usually asumed that the response to an alteration of our planet will be gradual, predictable, and reversible. However, abrupt changes are occasionally observed in nature and society.
Complex systems, ranging from the climate to ecosystems and society, can slowly lose resilience until even a minor perturbation can push them over a tipping point.
Rapid transformations and massive shifts can often be explained as so-called critical transitions.”
