Which outcome occurs when increased glacial melting causes large-scale freshwater discharge into subpolar ocean currents?

💡 Explanation

Thermohaline circulation weakens because freshwater addition reduces the water's density, therefore preventing deep water formation; rather than increasing upwelling/Coriolis since buoyant freshwater doesn't sink, or ENSO that is driven by atmospheric pressures.
