Yes. For example, several years ago, the En-ROADS Baseline projected a temperature of 4.1°C by 2100. As global policies evolved and new data became available, we recalibrated the model—first lowering the projection to 3.6°C to reflect recent trends in wind and solar deployment. In 2023, the Baseline was updated again to 3.3°C. This change reflected a mix of developments, including new estimates of the economic damages from climate change and more optimistic assumptions about average global carbon pricing.

All model updates, including changes to the Baseline Scenario, are documented in the En-ROADS User Guide release notes.
