Which effect occurs when increased meltwater influx disrupts thermohaline circulation within North Atlantic gyres?

💡 Explanation

When meltwater influx increases, thermohaline circulation weakens because freshwater reduces North Atlantic water density, inhibiting sinking and slowing the Gulf Stream's poleward heat transport. Therefore reduced heat transport results, rather than upwelling, sequestration, or a weakened jet which rely on different oceanographic/atmospheric conditions.
