What Actuaries Need to Know (and Avoid) in Cat Modeling

Recorded live at the 2025 CAS Annual Meeting in Austin, Texas, this episode of Almost Nowhere features Brandon Katz, Executive Vice President at KatRisk, in a deep dive on climate data, catastrophe modeling, and the limits of what models can tell us.

Brandon brings a rare perspective to insurance, with formal training in meteorology, climate science, and paleoclimatology, to unpack what we truly know about climate risk — and where uncertainty remains. The conversation explores how climate signals are (and aren’t) incorporated into catastrophe models, which perils have higher versus lower confidence, and how actuaries can responsibly interpret model outputs amid regulatory and stakeholder pressure.
