Extended Data Fig. 11: Comparison of predicted and observed ice-thickness changes in the Ross Sea region.
From: Antarctic ice dynamics amplified by Northern Hemisphere sea-level forcing
a, Predicted (lines) and observed (2σ error bars) ice thickness (in metres) above the modern thickness at Scott Coast site S (black) and sites 1 (red) and 3–5 (shades of blue) from ref. 35. The locations of the sites are indicated in b–e. Predictions are from simulations in which Northern Hemisphere ice cover is evolving according to ICE5G27 (solid lines) or is fixed (dashed lines). Observations are cosmogenic exposure age data from ref. 35. Red vertical bands represent the timing of AID events 1 and 2, as in Fig. 2c. b, Map of predicted ice thickness 12 ka in the Ross Sea, in the simulation with evolving Northern Hemisphere ice. c–e, The difference in ice thickness between 12 ka (b) and 11 ka (c), 10 ka (d) and 9 ka (e). See Methods for further discussion of these results.
