  • The mid-Cretaceous period was one of the warmest intervals of the past 140 million years 1 – 5 , driven by atmospheric carbon dioxide levels of around 1,000 parts per million by volume 6 . In the near absence of proximal geological records from south of the Antarctic Circle, it is disputed whether polar ice could exist under such environmental conditions. Here we use a sedimentary sequence recovered from the West Antarctic shelf—the southernmost Cretaceous record reported so far—and show that a… CONTINUE READING
