In his digest series Ask David, David Carlin explores the challenges sustainability teams face today, giving actionable advice on demonstrating financial value, strengthening business strategy, managing risk, and driving real organizational impact.
Most business planning assumes that change will be relatively gradual. Temperatures rise, risks intensify, markets respond, and organizations have time to adjust.
The climate system does not always behave this way. Some changes can become self-reinforcing once critical thresholds are crossed, shifting parts of the Earth system into fundamentally different states. These climate tipping points remain deeply uncertain, but their potentially far-reaching and irreversible consequences make them important for leaders making long-term decisions.
So, what are climate tipping points, when might we reach them, and how should businesses prepare?
What are climate tipping points and when might they be reached?
At its simplest, a climate tipping point is a threshold beyond which part of the Earth system begins to behave in a fundamentally different way. Feedback mechanisms can start to reinforce the initial change, making further disruption faster, harder to stop, or difficult to reverse on human timescales. However, considerable uncertainty remains about whether and when such a threshold might be crossed.
There is no single date or temperature at which the climate system reaches a tipping point. Different parts of the Earth system have different thresholds, levels of uncertainty, and timescales over which the consequences would unfold.
The most useful way to understand these thresholds is as a rising risk curve. Scientists estimate a range of temperatures over which each tipping point could be triggered. At the lower end, the probability may be relatively small. As warming increases, the likelihood rises, although the precise shape of that curve remains uncertain.
Some tipping elements may already be vulnerable at today’s level of warming. Research suggests that the risk of triggering multiple tipping points becomes appreciably greater between 1.5°C and 2°C, with further risks emerging as temperatures rise beyond 2°C. These are ranges rather than precise red lines, and scientists continue to debate the thresholds for individual systems.
Given the uncertainty, why do tipping points matter for business decisions?
This is the central question I raise when working with boards and senior leaders. Tipping points matter because businesses may need to make consequential decisions before the science can provide certainty about exactly when or where a threshold will be crossed.
Leaders therefore need to become comfortable operating in an era of radical uncertainty and irreducible complexity. More information will become available, alongside new risks, interactions, and sources of change. Waiting for complete clarity can itself become a consequential strategic decision.
The appropriate response is to build resilience across a range of plausible futures. Horizon scanning can help organizations identify weak signals, challenge assumptions, and understand where nonlinear change could affect their business. The objective is to make robust decisions before certainty arrives, preserve flexibility where possible, and prepare the organization to adapt as conditions change.
How should leaders integrate climate tipping points into strategic planning?
Leaders should identify which tipping points could affect their geographies, sectors, assets, customers, or critical dependencies. A major global shift may have little direct effect on day-to-day operations, while its consequences for water availability, food production, infrastructure, migration, or insurance could be highly material. The analysis should focus on the pathways that could realistically reach the business.
For uncertain but potentially high-impact events, the response might include insurance, diversification, contingency planning, staged investment, greater redundancy, or preserving strategic options. Organizations can also define indicators and decision triggers so that action is accelerated as evidence changes.
Tipping points should form part of the regular strategy process rather than becoming a separate climate exercise. They do not need to dominate every decision. However, excluding them can leave an organization exposed to an important source of future volatility, disruption, and strategic change.
