  abstract = {{W}e investigate the impact of {A}rctic sea ice loss on the {A}tlantic meridional overturning circulation ({AMOC}) and {N}orth {A}tlantic climate in a coupled general circulation model ({IPSL}-{CM}5{A}2) perturbation experiment, wherein {A}rctic sea ice is reduced until reaching an equilibrium of an ice-free summer. {A}fter several decades we observe {AMOC} weakening caused by reduced dense water formation in the {I}celand basin due to the warming of surface waters, and later compensated by intensification of dense water formation in the {W}estern {S}ubpolar {N}orth {A}tlantic. {C}onsequently, {AMOC} slightly weakens in deep, dense waters but recovers through shallower, less dense waters overturning. {I}n parallel, wind-driven intensification and southeastward expansion of the subpolar gyre cause a depth-extended cold anomaly similar to 2 degrees {C} around 50 degrees {N} that resembles the {N}orth {A}tlantic "warming hole." {W}e conclude that compensating dense water formations drive {AMOC} changes following sea ice retreat and that a warming hole can develop independently of the {AMOC} modulation.},
