Innovation, New Science, and Urgent Resilience Efforts: Transforming Caribbean Actuarial Practice in the Face of Climate Change

The Caribbean insurance sector faces an existential crisis. Hurricane Melissa's $2.2-4.2 billion insured losses in Jamaica exemplify an accelerating pattern of climate-driven catastrophes that challenge traditional actuarial assumptions. With economic losses consistently dwarfing insured losses, the widening protection gap leaves communities vulnerable and threatens industry viability.This presentation challenges Caribbean and international actuaries to move beyond reactive claims management toward proactive climate risk leadership. Climate change fundamentally disrupts the stationarity assumption underpinning conventional actuarial practice—the past is no longer prologue. Understanding climate scenarios through Representative Concentration Pathways (RCPs) and Shared Socioeconomic Pathways (SSPs) is now essential for responsible risk assessment and pricing.The Caribbean possesses world-class climate science capabilities that remain critically underutilized by insurers. The Jamaica Systemic Risk Assessment Tool (J-SRAT)—developed through collaboration between Oxford University, the University of the West Indies, and the Government of Jamaica—offers unprecedented granular analysis of climate risk hotspots, quantifying economic impacts in actuarial terms. The UWI Climate Studies Group's agricultural modelling using DSSAT and AquaCrop enables pre-planting yield predictions that could revolutionize agricultural insurance, yet these innovations remain largely academic without sector adoption.Actuaries must become change-makers. Opportunities exist to incentivize climate-resilient construction through innovative product design, fund research bridging academic excellence with practical application, and develop parametric insurance solutions informed by cutting-edge climate science. The profession faces a stark choice as to whether to continue business as usual while the protection gap widens and communities suffer or embrace transformation and lead the Caribbean toward climate resilience. The time for decisive action is now.
