Investigation of the role of regional topographic uplift caused by Jurassic continental breakup and subsequent mantle surface feedbacks. The paper finds that growth of the East Antarctica plateau and the Eocene uplift of the Gamburtsev Mountains pushed landscapes past the threshold for ice sheet nucleation about 45 million years ago, overcoming what would otherwise have been prohibitively warm temperatures

Abstract
Investigation of the role of regional topographic uplift caused by Jurassic continental breakup and subsequent mantle surface feedbacks. The paper finds that growth of the East Antarctica plateau and the Eocene uplift of the Gamburtsev Mountains pushed landscapes past the threshold for ice sheet nucleation about 45 million years ago, overcoming what would otherwise have been prohibitively warm temperatures
