Which mechanism disrupts thermohaline circulation significantly when Greenland ice melt increases drastically?

💡 Explanation

When ice melt increases, decreased water density from freshwater reduces sinking in North Atlantic because density gradients drive thermohaline circulation, weakening it. Therefore density decrease results, rather than salinity increase, temperature shifts, or oxygen changes which require different drivers.
