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

💡 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.
