The decline of Arctic sea ice area (SIA) has accelerated in recent decades and is projected to continue in a warming climate. This trend can be reversed by reducing atmospheric CO₂ concentrations. A large-ensemble model experiment, in which atmospheric CO₂ concentrations are quadrupled and then reduced to the initial state, shows an overall recovery of Arctic SIA by CO₂ removal, but at a slower rate than its decline to CO₂ increase.
