The First Antarctic Ice Sheet

Caption

Projection of the what the first Antarctic ice sheet might have looked like as the global climate cooled about 33.5 million years ago. Antarctica is in gray, with the ice sheet shown in meters of ice thickness. The ice sheet is continental in scale, but somewhat smaller than today. The estimate is based on prior modeling work of DeConto and Pollard and is supported by this new data study.
