Which outcome occurs when increased glacial meltwater streams significantly freshen North Atlantic surface waters?

A)Reduced North Atlantic Deep Water formation
B)Strengthened thermohaline current upwelling
C)Increased El Niño Southern Oscillation events
D)Accelerated global sea level decrease

💡 Explanation

Reduced salinity decreases water density, which reduces the rate of the North Atlantic Deep Water formation because density-driven *thermohaline circulation* is impeded; therefore, North Atlantic Deep Water formation is reduced, rather than upwelling increased, which requires denser water.
