The report detailed in this article, “Disconnected Defenses: Extreme Weather Risk Across Corporates, Cities and Financial Systems,” reveals a concerning trend: extreme weather events are no longer isolated incidents but are increasingly creating systemic financial risks that ripple through our interconnected global economy.
This comprehensive analysis, drawing on data from thousands of companies and governmental entities worldwide, highlights the interconnected nature of these risks and the urgent need for coordinated strategies to mitigate their escalating impact.
The Growing Systemic Nature of Extreme Weather Losses
For years, the scientific community has warned about the increasing frequency and intensity of extreme weather events due to climate change. Now, a significant report from the Carbon Disclosure Project (CDP) underscores that these events are not merely isolated disruptions but are actively weaving a web of interconnected financial risks across our global infrastructure, supply chains, insurance markets, and public services.
This systemic nature means that a single event can have cascading effects far beyond its immediate geographical impact.
Key Findings from the CDP Report
The CDP’s extensive “Disconnected Defenses” report analyzes disclosures from over 22,100 companies and more than 1,000 cities, states, and regions across 80 countries. While the number of companies providing full environmental data is substantial, a significant portion – only 35% – currently identify extreme weather as a material financial risk.
This indicates a potential blind spot in corporate risk assessment that needs immediate attention.
Quantifying Current and Future Losses
In 2025, companies reported direct financial losses from extreme weather totaling nearly $3 billion. These figures are broken down into direct costs of $309 million and an additional $266 million stemming from operational shutdowns.
Notably, heavy rain alone was responsible for $1.5 billion of these losses, illustrating the pervasive impact of even seemingly common weather phenomena when amplified.
Anticipating Future Financial Shocks
Looking ahead, companies anticipate future financial impacts from extreme weather to reach a staggering $898 billion. Flooding is predicted to be the most destructive element, accounting for $528 billion in anticipated losses, followed by cyclones at $161 billion and heavy rain at $86 billion.
The immediate threat is also significant, with almost half of surveyed firms (48%) expecting extreme weather risks to materialize within the next two years.
Understanding the Mechanisms of Loss
The primary drivers of these projected future losses are expected to be reduced production capacity, amounting to $326 billion, and asset impairment or early retirement, contributing $218 billion. This highlights how extreme weather directly impacts the physical assets and operational capabilities that underpin economic activity.
The Critical Need for Systemic Solutions
The report strongly emphasizes that the financial impacts of extreme weather are not confined to individual assets or specific sectors. Instead, these losses cascade through the very systems that businesses depend on, from transportation networks to energy grids and communication infrastructure.
This underscores a fundamental truth: site-level adaptation alone is insufficient. We require coordinated, system-wide responses to effectively manage these escalating risks.
The Disparity Between Risk and Mitigation Spending
A critical observation from the CDP report is the significant disparity between the costs companies face from extreme weather events and the investments they are making in mitigation.
The median company experiences risk costs of $39.4 million, yet the median mitigation spending stands at a mere $3.1 million.
This stark difference highlights a critical underinvestment in proactive resilience measures.
The Call for Coordinated Action
The authors of the report are unequivocal in their conclusion: addressing extreme weather as a systemic risk demands coordinated action.
This means collaboration between corporates, cities, and financial systems working in unison.
