The archaeological sites are vulnerable to overheating
Archaeological treasures that have been frozen for thousands of years are threatened according to British scientists because of global warming.
Remnants in some of the colder parts of the Earth are exposed when the ice melts, at high temperatures, endangering tombs and other important archaeological monuments.
Edinburgh University scientists who studied such phenomena in three different locations around the world called for an agreement through nations, to look at these changes and take measures to prevent them and preserve the treasures.
