Executive Summary
Recent reports argue that standard economic models underestimate climate damages by treating them as marginal shocks instead of structural, cascading risks. The strongest signal is a push to broaden climate-risk assessment beyond GDP and mean-temperature assumptions to include tail risks, regional shocks, insurance stress, and financial-system exposure.
Key Points
- Multiple reports argue that GDP-based climate damage functions understate physical losses and systemic disruption.
- A recurring criticism is that models rely too heavily on global average temperature and historical relationships, while missing regional shocks and non-linear effects.
- The financial stakes are framed through pensions, insurance, asset owners, and listed-company exposure to extreme-weather losses.
- Several sources call for broader metrics, including tail risk, distributional effects, mortality, and non-GDP welfare measures.
- The cluster shows a strong push for collaboration between climate scientists, economists, regulators, and asset managers.
- Supportive examples from UK asset owners suggest the modeling critique is influencing financial-risk governance, not just academic debate.
- A smaller historical thread explains how climate economics and integrated assessment models arrived at current assumptions, but current reporting is clearly dominant.
