A new study has found that 80% of UNESCO World Heritage sites are experiencing climate stress, with wood and stone structures particularly vulnerable to extreme weather conditions. The research highlights a significant Global North-South divide in conservation efforts, as countries in the Global South often lack the resources necessary to protect their cultural heritage. The study suggests that while a low-emission pathway could protect about 40% of threatened sites, current trends indicate a rise in global temperatures that could severely impact these landmarks. The researchers utilized 3D modeling to assess climate risks over time, revealing that no single mitigation strategy can uniformly safeguard these sites due to regional variations in climate impacts. The findings call for a collaborative approach to heritage conservation, emphasizing the importance of prioritizing resources and strategies based on specific material and regional needs.
