Well-being impacts of climate change, particularly on human integrity (Health) and living
conditions (Place), are severe but often underrepresented in Integrated Assessment Models
(IAMs). When included, these impacts are typically modelled using simplistic top-down
approaches, while bottom-up representations linking hazards to impacts, which offer high
transparency and process detail, are largely overlooked. Recent trends connecting IAMs
with the Impact, Adaptation, and Vulnerability (IAV) community offer an opportunity to
improve the representation of well-being damages. Here, we conduct a scoping review
resulting in a mapping of 37 modelling studies, revealing a diverse range of approaches,
with variation in hazards, impacts, and modelling choices. Key gaps include weak representation of inequality, a lack of multi-channel assessments, and an overrepresentation
of northern regions. We propose a roadmap to enhance climate impacts representation on
Health and Place in IAMs, using improved data and large-scale multiregional models to
generate results that better support decision-making.
