Continental breakup–driven uplift instigated East Antarctic Ice Sheet formation · T. Gernon et al.

Thomas M. Gernon1,2*†, Thea K. Hincks1†, Philip Goodwin1, Guy J. G. Paxman3, Sascha Brune2,4, Eelco J. Rohling1,5, Derek Keir1,6, Jean Braun2,4 Why Antarctica became glaciated ∼34 million years ago (Ma) remains debated, as relatively warm climates and sea temperatures appear inconsistent with ice sheet formation. Although a critical decline in CO2 is considered primarily responsible, evidence suggests that other factors were important, too. We investigated whether regional topographic uplift, rooted in Jurassic continental breakup and mantle-surface feedbacks, enabled nucleation of the East Antarctic Ice Sheet (EAIS). …
