Which impact results when Greenland's ice melt intensifies?

💡 Explanation

Reduced density causes less water to sink in Greenland, impacting thermohaline circulation; this leads to reduced North Atlantic Deep Water Formation because decreased sea surface salinity prevents the usual downward convection, therefore weakening this critical part of ocean current dynamics rather than alternatives.
