← GeographyWhich consequence results when extensive Antarctic ice melt disrupts deepwater formation?
A)Weakened global thermohaline circulation pattern✓
B)Increased seafloor methane hydrate stability
C)Polar jet stream intensification
D)Strengthened equatorial upwelling intensity
💡 Explanation
A reduction in dense, cold water formation near Antarctica weakens the global thermohaline circulation, because this sinking water drives deep ocean currents. Therefore, overall circulation decreases, rather than jet stream changes which occur more in atmosphere.
