Extended Data Fig. 1: Sensitivity of results to ice and Earth model parameters.
From: Antarctic ice dynamics amplified by Northern Hemisphere sea-level forcing
a, Changes in Antarctic ice volume predicted in simulations with evolving (solid lines) and fixed (dashed lines) Northern Hemisphere ice mass, and adopting the LVZ Earth model (Methods). Blue lines are identical to those in Fig. 2b, corresponding to a basal sliding coefficient of b = 10−5 m yr−1 Pa−2; red lines correspond to a basal sliding coefficient of b = 10−6 m yr−1 Pa−2. The black dotted line shows changes in Northern Hemisphere ice volume (right axis; in metres of global-mean sea level (gmsl) equivalent) prescribed in the ICE5G27 ice history. b, As in a, but adopting the HV Earth model (Methods). Blue (a) and red (b) vertical bands represent the timing of MWP and AID events, as in Fig. 2a, c, respectively.
