Ancient Mud Just Shattered a 750,000-Year-Old Ice Myth
Evidence of algae growth and climate simulations reveal the Arctic had seasonal ice, not a permanent ice shelf, for much of the past 750,000 years. These insights challenge long-standing theories. For a long time, researchers have debated whether a thick, continuous ice shelf once blanketed the entire Arctic Ocean during the most extreme ice ages. [...]
