Which consequence results when excessive glacial melting disrupts North Atlantic circulation?

💡 Explanation

A large influx of freshwater reduces seawater density, thereby inhibiting the North Atlantic Deep Water formation, because this change disrupts density-driven thermohaline circulation. Therefore, circulation weakens globally, rather than alternatives such as increased salinity.
