When the Ice is Gone

In "When the Ice Is Gone," geologist Paul Bierman recounts the groundbreaking discovery made in 2018 when centuries-old frozen soil from Greenland revealed perfectly preserved flora, indicating that the ice sheet had naturally melted 400,000 years ago. Through a historical lens, Bierman delves into the origins of ice coring at Camp Century, a former U.S. military base, while highlighting the implications of melting ice on global climate. He emphasizes the urgent need to address climate change in light of these revelations and their potential worldwide repercussions.
