In Greenland, climate change isn’t just a danger to ecosystems but also a threat to history, as global warming is affecting archaeological remains, according to a study. There are more than 1,80,000 archaeological sites across the Arctic, some dating back thousands of years, and previously these were protected by the characteristics of the soil. “Because the degradation rate is controlled by the soil temperature and moisture content, rising air temperatures and changes in precipitation during the frost-free season may lead to a loss of organic key elements such as archaeological wood, bone and ancient DNA,” the report, published in the scientific journal Nature, stated.
