Which climatic effect results when thermohaline circulation weakens due to increased freshwater input in North Atlantic?

💡 Explanation

When thermohaline circulation weakens, reduced northward heat transport occurs because the density gradient driving the current lessens inhibiting the Gulf Stream, leading to decreased warm water flow to higher latitudes. Therefore Northeastern North America cooling results, rather than increased hurricanes, Antarctic melting, or coral bleaching, which have different primary drivers.
