Which consequence results when increased freshwater input disrupts thermohaline dynamics in a subpolar gyre?

💡 Explanation

When freshwater increases, density decreases, hindering the sinking of surface water necessary for the thermohaline circulation, hence weakening sea ice formation due to warmer surface waters reducing albedo. Therefore albedo feedback diminish rather than other options, which wouldn't be directly linked.
