The author of the study and who researches ice sheet behavior, long-term, and landscape evolution at Durham University in the UK, Stewart Jamieson , told ABC News that for about 34 million years, ice has covered Antarctica. Before that, the continent had a comparatively warm climate similar to modern-day southern South America, such as the Patagonia region in Argentina and Chile.
