← GeographyWhich consequence results when excessive glacial melting disrupts North Atlantic circulation?
A)Weakened global thermohaline circulation✓
B)Increased ocean salinity globally
C)Accelerated deep ocean carbon sequestration
D)Enhanced equatorial upwelling intensity
💡 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.
