Figure 1. Relationship between atmospheric CO2 concentration and Antarctic ice volume (IMAGE)
Caption
Top right panel shows the model simulation of Antarctic ice sheet volume change covering the last 3 million years. Bottom right panel represents the relationship between atmospheric CO₂ concentration and Antarctic ice volume changes. Blue and orange lines show nonlinear fits for 1-0 million years ago and 3-1 million years ago, respectively, with shaded bands indicating the 95% uncertainty range. Maps on the left show representative Antarctic ice elevation changes under high-, transitional-, and low-CO₂ states.
