As temperatures rise, they are increasingly accompanied by climate volatility. Across much of the Northern Hemisphere, extreme heat and drought followed one of the wettest winters in recent history, leaving soil moisture levels depleted and fueling heightened wildfire activity. Elsewhere, severe flooding, storms, and prolonged droughts continue to affect communities and businesses across multiple continents. The economic consequences of these changes are impossible to ignore. In the EU alone, weather- and climate-related extremes caused an estimated €822bn in economic losses between 1980 and 2024. Roughly a quarter of that damage occurred during the last four years alone.

But a hotter climate does not only express itself through dramatic catastrophes. Often, losses emerge through slow, compounding changes that are less visible, but no less significant. Rising sea levels, changing rainfall patterns, declining water availability, and increasing heat stress are gradually reshaping the conditions in which businesses operate. Over time, these changes can affect agricultural yields, strain infrastructure, increase operating costs, disrupt transport networks, and alter the viability of entire regions.

These effects are being felt across virtually every part of the economy. From offices, data centers, and transport networks to energy infrastructure, agriculture, and global supply chains, businesses are confronting conditions for which many assets and systems were never designed. The consequences extend far beyond direct physical damage, including disruption to operations and personnel, supply shortages, commodity-price volatility, and higher costs.

For the insurance market, these developments present a significant challenge. Just as the climate is changing, so too is the nature of the risks it creates. As a result, historical loss data is becoming a less reliable guide to future exposure. To accurately price and transfer risk, insurers and reinsurers increasingly rely on forward-looking modelling, updated hazard assumptions, and more granular exposure data.

At the same time, the market continues to evolve. While traditional insurance remains central, insurers, reinsurers, and brokers are developing new ways to finance and transfer climate-related risk. From parametric insurance to captives, insurance-linked securities, and other alternative risk-transfer structures, organizations have access to a broader range of solutions than ever before. As climate volatility increases, businesses are combining these tools with conventional insurance to address exposures that may not be fully accommodated within traditional policies.

As global heating reshapes weather patterns, infrastructure pressures, and catastrophe exposures, climate resilience is becoming inseparable from insurability itself. A hotter, more volatile world has already arrived, and further change is still to come. To navigate this world successfully, organisations must understand their exposures, invest in adaptation, and integrate climate considerations into their future planning. Increasingly, resilience is a prerequisite – for securing insurance, accessing capital, and ensuring long-term business viability.
