"Unveiling Greenland's Ancient Soil: A Dire Warning for the Future"

Ancient soil samples extracted from beneath a mile-thick section of the Greenland ice sheet have revealed that about 400,000 years ago, large parts of Greenland were ice-free, with scrubby tundra and forests of spruce trees. This period, known as MIS 11, lasted for as much as 14,000 years and offers important insights into the Earth's natural warming and its potential implications for the future. The study warns that unless carbon dioxide levels in the atmosphere are dramatically reduced, Greenland could face a largely ice-free future, leading to rising sea levels and the inundation of coastal areas.
