“Policymakers “have severely underestimated” the risks of ecological “tipping points” – feedback mechanisms that could occur if certain thresholds are passed – a new study has found. Research published in the journal Science suggests that 45% of potential environmental collapses are interrelated and could amplify one another, highlighting ‘how overstressed and overlapping natural systems are combining to throw up a growing number of unwelcome surprises’, the Guardian writes. https://www.theguardian.com/environment/2018/dec/20/risks-of-domino-effect-of-tipping-points-greater-than-thought-study-says

Just 19% of the 30 types of ecosystem transitions studied were happening in isolation.”

There is no “could occur” about it.  The tipping point has occurred and the feedback mechanisms are spinning away with runaway increases in greenhouse gasses. At the moment, greenhouse gasses are increasing at a rate of over 50% per decade and this rate is also increasing.
