Climate Risk Quantification for Catastrophe Modelers
Quantify climate-driven catastrophe risks with scenario analysis and probabilistic modeling
What You Can Do
This skill helps catastrophe modelers and climate risk professionals quantify physical climate risks, analyze hazard frequency and severity trends, and generate probabilistic risk assessments for insurance, reinsurance, and investment portfolios. You can model climate scenarios, evaluate loss distributions across time horizons, and produce defensible risk metrics for stakeholder reporting and regulatory compliance.
Features
Incorporate IPCC climate projections and RCP/SSP scenarios into hazard frequency models. Adjust historical catastrophe data for changing climate conditions and evaluate compound risk from multiple perils.
Build probabilistic loss curves using empirical data and fitted distributions. Calculate Value-at-Risk (VaR), Tail-VaR, and return period losses for risk quantification and capital allocation.
Analyze trends in hurricane frequency, wildfire intensity, flood depth, and other climate-sensitive perils. Detect structural breaks and non-stationary behavior in historical catastrophe records.
Aggregate exposure-weighted risks across geographies, asset classes, and business lines. Account for correlation between climate perils and spatial clustering of losses.
Perform sensitivity analysis on frequency escalation, severity multipliers, and climate pathways. Generate stress test scenarios for board-level reporting and regulatory stress testing.
Access pre-built templates for risk register documentation, model assumptions, peer review checklists, and executive summary formatting aligned with industry standards.
Example Output
Example 1: Hurricane Frequency Projection
Historical rate (1981–2020): 6.8 major hurricanes/decade
RCP 4.5 (2050–2100): 9.2 major hurricanes/decade (+35%)
RCP 8.5 (2050–2100): 11.4 major hurricanes/decade (+68%)
Implied loss increase: 12% year-over-year growth in expected annual loss (EAL)
Example 2: Portfolio Loss Distribution
250-year return period loss: $850M (RCP 4.5, 2050 baseline)
99th percentile (1-in-100): $620M
Expected annual loss (EAL): $28.5M
Recommended capital reserve: $750M (+10% prudence factor)
Example 3: Compound Risk Scenario
Wildfire + drought compound effect on insured losses:
- Single peril model: $180M mean loss
- Compound scenario (2050): $310M mean loss (+72%)
Correlation coefficient: 0.68 (significant spatial clustering)
