A sweeping scientific assessment warns that climate tipping points are moving closer than markets assume, with cascading risks from ice sheets, ocean circulation, coral reefs and the Amazon. The same analysis outlines ‘positive tipping points’ in clean te
The latest Global Tipping Points Report 2025, published by the University of Exeter’s Global Systems Institute edited by Timothy M. Lenton and a consortium of more than 160 authors for, lands a stark message for boardrooms and risk committees. Global warming will soon overshoot 1.5°C, placing the economy in a danger zone where multiple climate tipping points can be triggered, with damages that cascade across food, water, infrastructure, and social systems. For finance, the implication is clear: linear risk tools will misprice nonlinear realities.
A new report on the current state of world climate health paints a starkly grim picture of a planet under critical threat.
The Global Tipping Points Report, published by the University of Exeter’s Global Systems Institute warns that several systems are already close to or past critical thresholds.
According to the study, published annually and edited this year by Timothy M. Lenton and a consortium of more than 160 authors, warns that global warming is imminently in danger of exceeding the 1.5°C threshold.
Warm-water coral reefs have crossed an estimated thermal tipping point around 1.2°C and are at risk of functional loss even under optimistic scenarios, threatening livelihoods for hundreds of millions and degrading natural coastal defenses.
Polar ice sheets are on paths that could lock in multi-meter sea-level rise over long horizons, imposing chronic costs on real assets and municipal finance.
The Atlantic Meridional Overturning Circulation, a key ocean conveyor, is assessed as at risk of collapse below 2°C, with profound consequences for European winters, West African monsoons, agricultural yields, and global supply chains.
The report also suggests the Amazon rainforest is facing extreme dieback risk in the 1.5°C to 2°C range, with consequences for biodiversity, regional climate, and economies tied to water and carbon cycles.
These systems, the report says, are interconnected, and most interactions are destabilizing.
Tipping one element raises the likelihood of tipping others, amplifying losses across sectors and regions.
The report frames the stakes as a human-rights issue as well as an economic one, arguing that preventing irreversible harm to the climate system is both prudential risk management and a legal imperative.
For financial institutions, that translates into governance expectations, with organizations being urged to integrate tipping risks into enterprise-wide assessments, scenario design, and board-level oversight before thresholds are crossed.
According to the study, waiting for certainty is, by definition, too late. Traditional risk matrices are not fit for purpose in this context, the authors contend.
They call for approaches that capture deep uncertainty, cascading effects, and irreversibility, including risk registers that translate Earth system dynamics into decision-useful ‘risk currencies’ for supervisors, banks, insurers, and asset owners.
