摘要: [1] Climate projections for the 21st century indicate a gradual decrease of Atlantic Meridional Overturning Circulation (AMOC). The weakening could be accelerated substantially by meltwater input from Greenland Ice Sheet (GIS). Here we repeat recent experiments conducted Intergovernmental Panel Change, providing an idealized additional source freshwater along Greenland’s coast. For conservative and high melting estimates, AMOC reduction is 35% 42%, respectively, compared to 30% original A1B scenario. Even estimate recovers in 22nd century. impact fresh water limited further enhancing static stability Irminger Labrador Seas, whereas backbone overturning maintained overflows across Greenland-Scotland Ridge. Our results suggest that abrupt climate change initiated GIS not realistic scenario Citation: Jungclaus, J. H., H. Haak, M. Esch, E.
