Beijing <\/strong>– As China initiates a nation-wide cultural heritage survey to log the state of the country\u2019s historical artifacts, researchers say ancient Buddhist murals in Dunhuang and Zhangye, Gansu province, are already under direct threat from unprecedented extreme rainfall linked to climate change, after lasting for centuries in dry, desert conditions.\u00b9 <\/p>\n\n Meeting in Beijing today, a group of cultural heritage conservation experts from the Dunhuang Research Academy and climate scientists from Greenpeace East Asia discussed the impact of extreme rainfall in Gansu, the connection to climate change, and what it means for China\u2019s cultural heritage.<\/p>\n\n \u201cAs the climate goes out of whack, deserts see downpour while farmlands get drought. Gansu is famous for its caves and the art stored inside them for centuries. Increased bouts of rainfall in the desert pose an acute risk. Spikes in humidity, flash floods, and cave ins are already happening. And by the time this cultural heritage survey is finished, some artifacts could already be gone,\u201d said Li Zhao, a senior researcher in Greenpeace East Asia\u2019s Beijing office. <\/p>\n\n Photos available here<\/a> and here<\/a>. <\/p>\n\n Since 2000, total rainfall in Gansu province has increased overall while the number of days with rainfall has actually decreased, resulting in a marked increase in bouts of extreme rainfall.\u00b2 Meanwhile, meteorological records show an average temperature increase of +0.28 degrees Celsius every 10 years between 1961 and 2021 in Gansu. This is faster than the global average. <\/p>\n\n Dunhuang\u2019s caves and grottoes are UNESCO World Heritage sites<\/a> that house paintings, sculptures, and libraries of scrolls stored by a local monastery. The caves date to the 4th century. Zhangye\u2019s cave monasteries are national level heritage site.\u00b3 <\/p>\n\n Researchers say these sites already show deterioration due to periods of high humidity and rapid fluctuations in humidity during extreme rainfall, as well as the impact of flooding and leaks: <\/p>\n\n \u201cWhile we\u2019re still working to document, understand, and conserve these pieces of our history, they\u2019re dissolved before our very eyes. This is a painful reality of the impact of climate change. The sites we looked at include some of the most well-funded, best staffed cultural heritage sites in China. And we can see this pernicious impact even in Dunhuang. There are hundreds of less-funded, less-studied sites all around China that are facing these same risks. The best thing we can do is stop climate change. But it\u2019s also urgent that we fund and support conservation efforts here,\u201d Li said.<\/p>\n\n END<\/strong><\/p>\n\n See report briefing (in Chinese) here<\/a>. <\/p>\n\n NOTES<\/p>\n\n [1] China\u2019s National Cultural Heritage Administration began a national cultural heritage survey this year.

As such, parts of Eastern Gansu would define extreme rainfall as more than 30mm of rain in one day, while parts of Western Gansu would define extreme rainfall as more than 10 mm of rain in one day. <\/p>\n\n [3] Source: http:\/\/www.gssn.gov.cn\/sngk\/jdtj\/201811\/t20181106_129434.html<\/a> (link in Mandarin Chinese)<\/p>\n\n [4] Source: http:\/\/news.sina.com.cn\/o\/2004-07-30\/00233239325s.shtml<\/a> (link in Mandarin Chinese)<\/p>\n\n <\/p>\n\n For media enquiries please contact:<\/strong><\/p>\n\n August Rick, Greenpeace East Asia, Beijing, (august.rick@greenpeace.org<\/a>), +86 175 1040 4599<\/p>\n\n\n
