4PLANET IMPACT / ISSUE
Climate tipping-point risk
Some components of the Earth system may undergo abrupt, self-reinforcing or difficult-to-reverse change beyond critical thresholds.
Why it matters
Tipping risks have different evidence levels and uncertainties and should not be reduced to a single countdown or deterministic date.
What the sources establish
IPCC AR6 assesses the possibility of large-scale, potentially irreversible changes as part of key climate risks, with uncertainty varying across systems and warming levels.

Published action
No project on this issue has passed the IMPACT publication gate yet. That is not evidence that no work exists.
Known and not established
- Do not state a tipping point's timing or probability without source-specific scientific evidence and uncertainty.
- This issue record is source-grounded context, not proof that any particular project, action or intervention is effective.
