Climate Change Stress Tests: the Implications for Insurers & Catastrophe Models

Presented by

Matthew Grant, InsTech London; Joss Matthewman, Senior Director, Climate Change Product Management & Strategy, RMS

About this talk

In this discussion with RMS we are continuing our theme of reviewing the impact of the Bank of England Climate Biennial Exploratory Scenario (CBES) released in June. Matthew Grant from InsTech London is talking with Joss Matthewman, Senior Director, Climate Change Product Management & Strategy at RMS. We begin by reviewing the cornerstones of climate change forecasting and terminology, breaking the various reporting requirements and outlooks into their fundamental elements. Using the different Representative Concentration Pathways (RCP) and the corresponding temperature increases, Matthew and Joss review what the physical changes to catastrophic loss could be and how these can be represented in a model. Issues such as climate conditioning of models, and why these require key changes in how catastrophe models are provided and used are identified with useful guidelines for users of RMS and other models.
