Simple Explanation (ELI5)

Think of our historical treasures as a precious old library. Climate change is like a rising tide of unpredictable storms threatening to flood the building. Experts have created over 80 different risk maps (RAFMs) to figure out how to save the books, but some maps only look at the physical walls while others look at how the librarians can save the stories. We need a common language to combine these maps and protect both the building and the tales inside.

Key Advantages & Current Limits

🟢 Pros: Employs a robust scientific triad (hazard-exposure-vulnerability) and fosters vital interdisciplinary integration of climate, hydrological, and archaeological models. 🟢 Pros: Highlights the crucial role of local community and stakeholder participation to gather culturally relevant exposure data and vulnerability thresholds. 🔴 Cons: Reveals significant inconsistency and confusion in defining 'vulnerability' (structural vs. socio-economic), hindering comparability across frameworks. 🔴 Cons: Largely overlooks intangible cultural heritage (oral traditions, rituals), focusing predominantly on physical assets and material structures.

Future Outlook & Takeaways

Over the next 3-5 years, the standardization of assessment criteria and the adoption of a common vocabulary will enable more comparable and cohesive risk frameworks. Integrating multiple climate scenarios (RCP 2.6, 4.5, 8.5) and sharing data in open formats like GeoJSON and CSV will facilitate global databases, turning theoretical risk assessments into concrete, actionable plans to safeguard both physical monuments and local oral traditions.

How Can Climate Threaten Our Historical Treasures?

Climate change is not only about higher temperatures or stronger hurricanes: it also threatens monuments, museums, and traditions that tell our story. To better grasp these dangers, experts have developed over 80 risk assessment frameworks (RAFMs). These tools combine IPCC climate projections with international guidelines like the Sendai Framework and the UN Sustainable Development Goals. In practice, they examine three key elements: hazard (e.g., floods, heatwaves), exposure (how many cultural assets are at risk) and vulnerability (how sensitive or unprotected they are). Some RAFMs have shown good practices, such as involving local communities, using multiple climate scenarios, and considering risks at multiple scales (from neighborhood to nation). Yet gaps remain: vulnerability definitions are often confused, methods are too case‑specific, and little attention is given to intangible heritage like oral traditions. To make protection more effective, scholars propose standardising criteria, fostering collaboration among climatologists, archaeologists and administrators, and turning results into concrete action plans. This way, our treasures can withstand a rapidly changing climate.

The 86 risk assessment methodologies (RAFMs) examined in the study differ in their conceptual structure, which relies on the IPCC's hazard‑exposure‑vulnerability (HEV) triad. However, the review highlights considerable heterogeneity in the definition of vulnerability: some RAFMs equate it with structural weakness, others link it to socio‑economic factors, creating comparability challenges. Another critical issue is the limited integration of intangible heritage (rituals, languages, artistic practices) into the models, which remain focused on material assets. To address these gaps, the authors propose adopting a common vocabulary inspired by the Global Framework for Disaster Risk Reduction and using multiple climate scenarios (RCP 2.6, 4.5, 8.5) to assess long‑term sensitivity. Moreover, active participation of local stakeholders—curators, indigenous communities, administrators—is deemed essential for gathering more accurate exposure data and defining culturally relevant vulnerability thresholds. Interdisciplinarity is another cornerstone: integrating hydrological, thermal and erosion models with archaeological analyses enables simulation of impacts at micro‑scale (e.g., fresco deterioration) and macro‑scale (e.g., loss of entire archaeological sites). Finally, standardising results in open formats (GeoJSON, CSV) promotes data sharing among institutions and the creation of global databases, indispensable for monitoring the evolution of climate risk to cultural heritage worldwide.
