Abstract

The evidence of persistent cold paleoclimate contradicts the postulated Pliocene deglaciation of East Antarctica, which requires atmospheric temperatures 20°C warmer than present to produce melting ablation surfaces on the East Antarctic Ice Sheet. Furthermore, an East Antarctic outlet glacier has not expanded into east-central Wright Valley in at least the last 3.8 Ma, thus precluding ice-sheet overriding of the Dry Valleys region during this interval. Overall, Wright Valley data imply that the adjacent East Antarctic Ice Sheet has been stable for at least the last 3.8 Ma
