Climate Risk Quantification for Catastrophe Modeling
Translate climate data into catastrophe model inputs for underwriting
What You Can Do
You analyze diverse climate datasets, quantify emerging climate risks, and generate underwriting-ready catastrophe model parameters. This skill converts complex climate science into actionable inputs for risk assessment, enabling you to stress-test portfolios against climate scenarios and refine model calibration with empirical climate trends.
Features
Aggregate and standardize data from multiple climate sources—satellite observations, weather stations, reanalysis datasets—into unified formats for analysis.
Convert climate metrics (temperature trends, precipitation anomalies, extreme event frequency) into probability distributions and model parameters.
Generate or adjust intensity curves, frequency distributions, and loss correlation inputs based on observed climate patterns and historical extremes.
Translate regional climate projections and hazard assessments to underwriting zones, accounting for spatial heterogeneity in climate impacts.
Build consistent climate scenarios (RCP, SSP pathways) and stress catastrophe models across multiple futures to quantify tail risk.
Extract secular trends, cyclical patterns, and volatility from climate observations to inform model assumptions about non-stationarity.
Implement backtesting, sensitivity analysis, and uncertainty quantification to verify model inputs against historical performance and expert judgment.
Example Output
Climate Risk Assessment Output:
- Temperature trend: +0.18°C per decade (95% CI: ±0.08°C) for coastal region
- Hurricane intensity parameter: μ = 6.2, σ = 0.9 (updated from historical 6.0 ± 0.8)
- Loss exceedance curve: $10B event frequency rising from 1-in-100 to 1-in-85 by 2040
Catastrophe Model Inputs (XML-ready):
<peril code="TRO">
<intensity_curve trend="+0.15" ci_lower="-0.05" ci_upper="+0.25"/>
<frequency annual="0.0118" scenario="ssp245"/>
<correlation portfolio="0.42" uncertainty="0.08"/>
</peril>
Portfolio Stress Test Summary:
- Base case (historical): Expected Annual Loss = $2.1M
- +1.5°C scenario: Expected Annual Loss = $2.8M (+33%)
- +3°C scenario: Expected Annual Loss = $4.2M (+100%)
- Key risk driver: Tropical cyclone intensification; frequency stable
