Which large-scale effect results when cold stream runoff reduces thermohaline circulation?

A)Weakening of Atlantic Meridional Overturning
B)Increased global ice sheet formation rate
C)Strengthened equatorial trade wind patterns
D)Expansion of tropical rainforest biomes

💡 Explanation

Freshwater influx reduces ocean salinity, hindering the density-driven Sinking. This weakens the Atlantic Meridional Overturning Circulation because density stratification reduces, therefore the ocean currents slow rather than accelerate the energy transport.
