Session 3: A Prototype Actuaries Climate Risk Index

Thank you

This live web event has ended. Thank you for attending.



Steve and Tatjana are members of the CAS Climate Change Task Force tasked with climate change research that is currently focused on climate risk analytics. This session will present the development of a prototype Climate Risk Index by modeling US Disaster costs using climate extreme components of the Actuaries Climate Index (ACI) and other tools. The session will show how predictive ACI climate-extreme component measures explain growth in catastrophic disaster losses due to climate risk. The work of the CAS Climate Change Task Force will also illustrate how to construct frequency and severity trend models from aggregate risk data.

The presentation will also include a look at other climate risk analytic solutions, based on a review of available literature, including FEMA's National Risk Index.

Learning Objectives:

  1. Gain familiarity with the Actuaries Climate Index and a prototype Climate Risk Index.
  2. Know where to find Aggregate Catastrophe Data and how to prepare it for modeling.
