What Happens When Disruption Becomes the New Normal?

What Happens When Disruption Becomes the New Normal?

Reflections from a BEI x IMechE debate during London Climate Action Week titled: “Is Climate Adaptation the New Common Ground?”

By Martin Townsend, Director at the Centre of Excellence for Sustainability BSI (British Standards Institution)

We built many of our modern systems on the assumption that tomorrow would broadly resemble yesterday. Whether discussing water resilience, flood preparedness, infrastructure investment, energy systems, insurance markets, fragile states, supply chains or economic growth, the same underlying tension now seems to surface almost everywhere. Many of the systems modern societies depend on every day were designed for a world that assumed greater stability, predictability and separation between risks than the one we now appear to be entering. What is striking is that this conversation is no longer confined to climate specialists or resilience professionals. Increasingly, it is emerging in boardrooms, government departments, infrastructure planning discussions, investment conversations and local communities alike. Though sector-specific language varies, the core concern is often remarkably similar.

But what happens when disruption stops being occasional and starts becoming structural?

During London Climate Action Week, British Expertise International and IMechE explored this question and examined whether climate adaptation is becoming a new common ground across infrastructure, finance, governance, and society, and whether this will truly build long-term resilience across all aspects of society.

Mitigation vs adaptation

Climate mitigation has become increasingly difficult terrain. The rightward political drift across much of Europe and North America, the fracturing of international climate coalitions, and a growing perception that net zero has become ideologically freighted have made ambitious mitigation commitments harder to sustain – and, in some contexts, harder to defend publicly.

Adaptation offers something different. Because it deals with what is already happening – the flooding, the heat, the infrastructure failures, the insurance gaps – it sidesteps much of that ideological friction. The case for adaptation does not depend on agreement about its causes, so it can command support across political divides that have made mitigation increasingly difficult to discuss. But that shift deserves scrutiny. If adaptation becomes a substitute narrative rather than a complement to mitigation, a world that has stopped trying to limit warming will have far more than 3°C to adapt to.

The shifting landscape

For many years, much of the climate conversation quite rightly centred on mitigation. Reducing emissions, accelerating the transition to lower-carbon economies and driving investment into cleaner technologies remain essential priorities. Nothing about the growing focus on resilience or adaptation changes that reality. We still need to decarbonise at pace, rethink patterns of consumption and reduce pressure on already strained water and energy systems in ways that many economies and political systems have historically struggled to confront honestly.

At the same time, adaptation is no longer a future-facing issue beyond the horizon of current decision-making. Increasingly, it is an operational reality shaping investment decisions, infrastructure planning, governance discussions and public expectations in the present. Heatwaves are beginning to reshape conversations about productivity, health systems and urban design. Flooding is influencing insurance models, investment confidence and local planning assumptions. Water stress is moving from an environmental concern to a strategic and economic one. Energy systems are facing new forms of volatility and interconnected risk. What is increasingly clear is that climate pressure rarely arrives in isolation. It intersects with geopolitical instability, financial fragility, ageing infrastructure, cyber vulnerability, migration pressures and declining public trust, rapidly exposing weaknesses in systems that were never designed to absorb multiple overlapping stresses at the same time.

In the past, climate, infrastructure, governance, finance and social resilience were often treated as adjacent but fundamentally separate conversations. Increasingly, they appear to be converging into a single discussion as climate pressures expose the interdependence of systems previously considered independently manageable. That shift changes the role of infrastructure, governance, finance and policy. It also changes the role of standards, assurance and shared frameworks, because fragmented systems operating under sustained pressure struggle to adapt coherently without trusted forms of coordination, interoperability and accountability.

Building resilient systems amid a polycrisis

In recent years, the term “polycrisis” has become increasingly common to describe this phenomenon. Yet perhaps the most important aspect of the idea is not the terminology itself, but the recognition that many societies are entering a period in which disruption feels less episodic and more continuous. That changes everything. Systems behave very differently under sustained pressure than during isolated shocks.

For decades, many organisations, institutions and economies optimised primarily for efficiency, scale and cost reduction. Lean supply chains, centralised infrastructure, just-in-time delivery models and maximum utilisation were often seen as signs of progress, competitiveness and modernity. In relatively stable conditions, these approaches delivered enormous benefits and transformed living standards across much of the world. Yet one of the more uncomfortable questions now emerging is whether, in some areas, we also engineered brittleness into our systems while describing the process as optimisation.

Only now are we beginning to understand how often efficiency and resilience were quietly pulling in opposite directions. Highly efficient systems can become highly fragile when disruption shifts from occasional to continuous, particularly when there is insufficient redundancy, flexibility or adaptive capacity built into the wider system around them.  One of the defining resilience questions of the coming decade may not simply be how we protect systems from disruption, but whether the systems themselves can adapt coherently under sustained pressure without losing legitimacy, functionality or public trust. That is a much deeper and more uncomfortable challenge than resilience is sometimes presented as.

Resilience and social cohesion 

Resilience is often framed primarily as an engineering problem, requiring stronger physical assets, larger defences or more robust technical capability. These remain critically important, and no serious resilience conversation can ignore the importance of physical infrastructure. However, as these discussions continue across sectors and contexts, it becomes clearer that resilience is also profoundly shaped by governance, coordination, institutional trust, local capability and social cohesion. Highly advanced infrastructure can still exist within fragile systems if the surrounding governance structures lack adaptability or legitimacy.

Equally, communities with fewer resources can sometimes demonstrate extraordinary resilience because relationships, trust, local knowledge and social cohesion remain strong even under pressure. Perhaps one of the most important resilience lessons now emerging globally is that social cohesion itself is a form of infrastructure. That feels particularly relevant in discussions about fragile and conflict-affected settings, where resilience often depends just as much on local ownership, institutional legitimacy and trusted relationships as on physical assets alone. In many respects, these environments simply expose earlier the kinds of interconnected pressures that other societies are now beginning to experience more frequently.

The same themes are increasingly evident in domestic resilience discussions. Conversations about flood preparedness, infrastructure resilience and local adaptive capacity repeatedly return to the importance of delivery capacity, trusted partnerships, long-term investment confidence and coordination between national strategy and local implementation. There is growing recognition that resilience cannot simply be imposed from the centre outward through infrastructure investment alone. It must also be built through relationships, coordination, adaptive capability and public trust at the local level.

Water resilience perhaps illustrates this tension particularly clearly, because long-term security cannot realistically be achieved through infrastructure expansion alone. Infrastructure investment matters enormously, but so do governance, demand management, leakage reduction, catchment management, public behaviour and the willingness to engage honestly with the reality that no society can build infinite resilience around infinite consumption. That is not simply an environmental challenge, but an economic, political and societal one.

What next?

There is also a growing risk that resilience itself becomes unevenly distributed. Wealthier organisations, nations and communities are often better placed to absorb shocks, adapt quickly and recover from disruption, while others face escalating pressure with far fewer resources or less institutional support. That raises difficult but necessary questions. Who gets protected first? Which communities receive long-term investment? What level of resilience becomes affordable only to wealthier societies or organisations? At what point does resilience become not simply a technical challenge but a question of legitimacy and fairness? These questions matter because resilience ultimately depends on trust.

The challenge ahead is not simply about building stronger assets or responding more effectively to isolated crises after they occur. Increasingly, it feels as though the deeper question concerns whether societies themselves can adapt to sustained uncertainty without losing trust, fairness, coordination and stability. For a long time, we largely measured progress by growth, speed, efficiency and optimisation; however, the defining characteristic of successful societies may become something else entirely. Their ability to absorb pressure without losing trust. Their ability to adapt without abandoning fairness. Their ability to endure stress without fragmenting socially, economically or institutionally. That feels like a very different test of progress from the one many of our systems were originally designed for. And perhaps that is the real conversation now beginning to emerge beneath the language of climate adaptation and mitigation.
