Extended Data Fig. 5: Global to regional Antarctic temperature conversion (based on the quasi-static experiment).
From: Mapping tipping risks from Antarctic ice basins under global warming
Sea-level relevant ice volume (in metres sea-level equivalent, m SLE) as a function of Antarctic mean surface temperature change, based on the quasi-static experiment (using a warming rate of 0.0001 °C yr−1 above pre-industrial levels), showing the model sensitivity to variations in the scaling factors used to convert global temperature changes into Antarctic regional surface air (θatm) and ocean (θocn) temperature changes, derived from long-term global climate model output (ref. 114). The thick dark blue line represents the reference simulation. The inset shows a zoom into the lower temperature regime, with ice volumes plotted as a function of circum-Antarctic ocean temperature change, the primary driver of ice loss at low warming levels.
