Which risk increases when glacial meltwater disrupts North Atlantic circulation?

💡 Explanation

Reduced salinity from meltwater slows down the Thermohaline Circulation due to decreased density differences at high latitudes; this inhibits North Atlantic Deep Water formation because the density gradient weakens; therefore the ocean absorbs less CO2, rather than alternatives related to oxygen, nutrients, or coastal currents.
