AI Summary
A study in Nature Geoscience by researchers at the IBS Center for Climate Physics, Pusan National University, finds that the Antarctic ice sheet’s sensitivity to climate forcing increased sharply after a major shift in Earth’s ice‑age cycles about one million years ago, when ice ages became longer and more intense. The paper presents nonlinear fits linking atmospheric CO₂ levels to Antarctic ice volume for the periods 3–1 million years ago and 1–0 million years ago, with uncertainty ranges shown.
