Which outcome occurs when substantial Antarctic ice sheet melting increases freshwater input into the Southern Ocean?

💡 Explanation

Freshwater input reduces seawater density, hindering sinking, because it disrupts the density gradient that drives thermohaline circulation. This weakened meridional overturning circulation results therefore diminishing heat transport, rather than alternatives like boosted carbon uptake dependent on biological processes.
