This paper shows that current climate policies risk triggering tipping points like permafrost thaw and rainforest loss. While these changes add some extra warming, human emissions remain the biggest driver. Lower emissions reduce the risk, but reaching tipping points is still possible.

Short summary
We investigate the probabilities of triggering climate tipping points under various emission scenarios and how they are altered by additional carbon emissions from the tipping of the Amazon and permafrost. We find that there is a high risk for triggering climate tipping points under a scenario comparable to current policies. However, the additional warming and hence the additional risk of triggering other climate tipping points from the tipping of the Amazon and permafrost remain small.
