Predicted Respite for Insurers from Natural Disasters Unlikely in 2025, according to Willis
Preparing for a New Era of Climate Extremes: Insights from the Willis Natural Catastrophe Review
The latest Willis Natural Catastrophe Review, a biannual publication by WTW business, sheds light on the escalating risks of natural catastrophes in the face of climate change. The report, published in 2025, offers valuable insights and strategies for mitigating future risks.
A Shift in the Climate Landscape
The review underscores a persistent trend of insured losses exceeding USD 100 billion annually for six consecutive years. This trend is expected to continue in 2025, driven by severe events such as wildfires in Los Angeles, Japan, South Korea, and an above-average U.S. tornado season.
The severity and scale of these catastrophes highlight the need to confront a new era of climate extremes. Efforts to keep global warming below 2°C appear to be falling short, shifting the focus towards adaptation and resilience building.
Risk Reassessment and Adaptation Strategies
Risk managers are advised to reassess exposure by integrating advanced climate forecasts and scientific advances into their risk models and planning. This includes leveraging seasonal weather forecasts to anticipate and prepare for elevated catastrophe risk in specific geographic regions over the next 3 to 6 months.
Improved wildfire risk modeling is crucial, particularly in high-exposure zones like the urban-wildland interface. Models should incorporate current fire weather conditions, up-to-date fuel profiles, and the dynamics of wildland fire transitioning into urban conflagrations. This is crucial due to the catastrophic Los Angeles wildfires which alone incurred about USD 40 billion in insured losses in early 2025.
Optimizing Insurance and Risk Frameworks
Insurers and reinsurers face immediate pressure on catastrophe loss budgets and must ensure their risk frameworks are optimized to handle evolving threats. Closing protection gaps with data-driven solutions is a priority to maintain resilience in the face of rapid climate change.
A Call for Action
The Willis Natural Catastrophe Review highlights a future risk landscape of increasing severity and frequency of natural catastrophes driven by climate change. The report advocates scientifically informed risk reassessment, resilient adaptation measures, and enhancement of insurance modeling as foundational strategies to mitigate future catastrophe risks under climate change.
As we navigate this new era of climate extremes, it is crucial that we take steps to build resilience and adapt to the changing climate.
