A polar research team measures increasing meltwater input from an ice sheet into the North Atlantic. They note that this freshwater is less dense than salty seawater and can inhibit deep-water formation. Which outcome is the most plausible consequence for thermohaline circulation under continued warming and ice melt?
The same warming also contributes to sea-level rise via thermal expansion and increases coral bleaching risk in lower latitudes.
