Overview

• The study, published in *Earth System Dynamics*, quantifies a 62% average risk of triggering multiple climate tipping points under existing global policies.
• Scientists assessed 16 Earth system components, including ice sheets, coral reefs, and vast forests, to evaluate tipping point probabilities across five socioeconomic scenarios.
• Findings indicate that carbon released by Amazon rainforest dieback and permafrost thaw is unlikely to trigger cascading tipping events in other systems.
• Adopting sustainable, lower-emission pathways significantly reduces the risk of crossing critical thresholds, offering a window for preventive action.
• Experts call for urgent global action and the activation of 'positive tipping points' in societal and economic systems to ensure a sustainable future.
