As a result of rising temperatures, extreme weather such as hurricanes, drought, floods and heatwaves has become increasingly common and more intense, warn researchers.
According to a report from UNESCO, 73 percent of all 1,172 non-marine sites on UNESCO's World Heritage list are exposed to at least one serious risk related to water, such as drought or floods.
This applies, for example, to the mausoleum Taj Mahal in India. The World Heritage site is "facing water scarcity that increases pollution and depletes groundwater, which damages the mausoleum", according to the report.
In Peru, the ancient city and World Heritage site Chan Chan is at risk of being affected by river floods. The site is particularly vulnerable due to its 1,000-year-old adobe walls.
