Proprietary algorithms, scientifically derived weather and climate models, and the complementary expertise of specialized partners could be the difference maker that helps a (re)insurer navigate a turbulent and changing climate. (ink drop/Adobe Stock)
Natural catastrophe claims are on an uneven but upward path for U.S. property& casualty insurers. The average was $100 billion from 2017 through 2021, up from less than $50 billion in the previous five-year period. Heightened awareness of climate change might suggest that our warming planet is the leading cause, but closer analysis points to a more nuanced perspective:
- Comparing any two five-year periods can give a false impression of longer-term trends because of extreme variability in natural catastrophe experience. Verisk's modeling suggests it's not rare for average losses to exceed $100 billion in any five-year span.
- Climate change indeed affects multiple atmospheric perils in various ways, from precipitation patterns in wildfire-prone areas to the effects of ocean temperatures on hurricane activity.
- Legal and regulatory trends, such as increasingly costly claims litigation and broader coverage requirements, are adding a man-made factor to rising catastrophe claims.
For insurers and reinsurers, the way forward through these complex challenges is preparedness. This article, the first in a series, examines the overall importance of data and analytics in navigating natural catastrophe risk.
