Climate Risk Modelling: From Scenario Narratives to Quantified Financial Loss
By Jonas Osman
Explains how climate narratives are converted into risk factors, exposures, shocks, losses, and capital metrics.
By Jonas Osman
Climate risk modelling requires more than generic ESG commentary. It needs hazard-level data, scenario design, exposure mapping, vulnerability functions, calibration, validation, uncertainty testing, and clear governance. This library collects Jonas Osman's research notes and modelling frameworks across physical risk, transition risk, financial impact modelling, insurance loss modelling, and regulatory climate stress testing.
