Which effect increases following sea ice melt amplification?

💡 Explanation

Increased sea ice melt causes runoff dilution, driving enhanced stratification; this weakens vertical salinity gradients needed for convective overturning because decreased dense water formation reduces thermohaline circulation, therefore the sea surface freshens rather than maintains density for sinking.
