← GeographyWhich consequence results with increased Antarctic glacial melting?
A)Decreasing global thermohaline circulation strength✓
B)Increased equatorial upwelling intensity
C)Strengthened atmospheric Hadley cell circulation
D)Expansion Walker cell over Pacific Ocean
💡 Explanation
A large influx of freshwater from melting glaciers reduces ocean salinity, hindering the North Atlantic Deep Water formation critical to thermohaline circulation; because salinity difference drives density gradients. Therefore, circulation weakens, rather than upwelling increasing due to altered stratification.
