The dawn of the Antarctic ice sheets: new study reveals it took millions of years for ice to cover Antarctica

Major differences in the way that Antarctica’s ice sheets formed millions of years ago could be the reason why ice is melting faster today than predicted, especially in West Antarctica, an international research team has discovered. The surprising findings, detailed in unique geological sediment samples from drill cores, provide insights into when and where today’s Antarctic ice sheets formed.
