In CPCU 500, anticipating what could go wrong requires recognizing emerging and evolving risk drivers that can change both thefrequencyandseverityof loss. The actions described—tightening underwriting forrisk concentration, recalibrating models to reflectrecent event experience, and advocating for strongerbuilding codes—are hallmark responses toclimate changeand related catastrophe trends.
Climate change is associated with shifting hazard patterns and more volatile weather-related loss experience, which creates problems for insurers that rely on historical loss data and stable probability assumptions. When recent catastrophe experience changes materially, insurers often adjust catastrophe and pricing models to better reflect updated conditions. They also pay closer attention toaccumulationandconcentration risk, because correlated events (for example, hurricanes, wildfires, convective storms, or flood) can produce many losses at once within the same geographic area or portfolio segment, stressing capacity and surplus.
Building code advocacy fits the same challenge: as hazards intensify or expand, improvingresiliencereduces expected losses by making structures better able to withstand wind, fire, flood, and other catastrophe perils. From a risk management perspective, stronger codes are a form ofloss controlthat can improve long-term insurability and affordability.
The other options do not match as well. Pandemic responses focus more on business interruption disputes, exclusions, and operational continuity. Litigation-driven inflation is addressed through claims strategies and tort risk management. Terrorism responses center on terrorism modeling and specialized coverage programs.
