A pronounced decline in Antarctic sea ice has been observed since 2014, with major changes in the Earth system. This study investigates whether these impacts can be reversed by removing atmospheric greenhouse gases. Using carbon dioxide removal experiments from the Coupled Model Intercomparison Project Phase 6, we identify considerable inter-model diversity in projections of Antarctic sea ice recovery, partly driven by a positive feedback loop starting from different initial ocean stratification in the present climate.
