AMOC Stabilization Under the Interaction With Tipping Polar Ice Sheets

Several large-scale components of the climate system may undergo a rapid transition as critical conditions are exceeded. These tipping elements also dynamically coupled, allowing for global domino effect under warming. Here we focus on such cascading events involving Greenland Ice Sheet (GIS), West Antarctica (WAIS) and Atlantic Meridional Overturning Circulation (AMOC). Using conceptual model, study combined behavior due to three dominant feedbacks: marine ice sheet instability WAIS, height-surface mass balance feedback GIS salt-advection AMOC. We show that, in realistic parameter range WAIS can inhibit by preserving AMOC stability.
