Noah News covered the launch of Scientific Climate Ratings’ Sovereign Climate Risk Ratings, highlighting a new framework that translates chronic physical climate risk into forward-looking macroeconomic impacts for sovereign economies.

The article explains how the ratings move beyond broad measures of climate exposure by quantifying the expected effect of rising temperatures on GDP, providing investors, lenders and policymakers with financially meaningful climate risk metrics.

Key features of the framework include:

• Coverage of 191 countries and more than 3,400 subnational regions, representing over 95% of global economic output.
• Subnational modelling that captures regional differences in climate exposure, economic activity and population, producing more robust sovereign assessments.
• Probability-weighted analysis across nine climate pathways, generating an expected scenario that serves as the basis for the sovereign rating scale.
• Forward-looking sovereign ratings from A to G, helping financial markets identify structural climate risks before they are fully reflected in valuations and sovereign spreads.

The article highlights how Sovereign Climate Risk Ratings provide a science-based, financially interpretable framework for integrating chronic physical climate risk into sovereign analysis and long-term investment decisions.
