Randomized trial examines the impact of Greenland meltwater on AMOC, highlighting climate implications.

This research investigates how Greenland meltwater influences the Atlantic Meridional Overturning Circulation (AMOC).
Conducted three hosing experiments with the eddy-rich climate model EC-Earth3P-VHR over 21 years.
Utilized spatial and monthly meltwater distribution data from observations, averaging 0.04 Sv annually.
Analyzed the response of salinity and temperature in currents associated with the AMOC.
Reduced salinity observed in Greenland and Labrador currents within the first year.
AMOC weakened by nearly 3 Sv at subpolar latitudes, showing a 20% reduction.
By the end of the simulation, a 10% average decrease in AMOC was noted across the entire Northern Hemisphere.

Martin-Martinez et al. (2026) studied this question.
