Climate tipping points are thresholds in the Earth’s system that, once crossed, can lead to rapid and irreversible environmental changes. While 16 potential tipping elements have been identified—such as melting ice sheets and shifting ocean currents—much remains uncertain about when and how these changes could unfold.
For Australian decision-makers, there is currently no strong indication that tipping points will significantly shift climate projections before 2100. However, risks like accelerated sea-level rise from collapsing ice sheets may warrant closer consideration in some areas. The fact sheet below provides clear, practical guidance on how tipping point scenarios might influence long-term planning and highlights why emission reductions remain critical.
