The current crop of models assessed by the Intergovernmental Panel on Climate Change to produce their assessment reports lack endogenous process-based representations of climate-driven changes to human activities, limiting understanding of the feedback between climate and humans. FRIDA (Feedback-based knowledge Repository for IntegrateD Assessments) v2.1 integrates these systems and generate results that suggest standard scenarios the shared socioeconomic pathways baseline scenarios may overestimate economic growth, highlighting the importance of feedbacks for realistic projections and informed policymaking.

Climate models often exclude human behaviour. We introduce a model that includes economic, social, and environmental factors that influence dietary choices. This helps us understand how behaviour shifts impact future emissions and climate conditions. By considering a range of plausible behaviours, we provide a more accurate picture of potential outcomes, improving representations in climate models.
