← GeographyWhich outcome increases when glacial melt disrupts NADW?
A)Lower Arctic sea ice formation
B)Decreased global ocean salinity✓
C)Regional North Atlantic warming
D)Increased deep ocean ventilation
💡 Explanation
Reduced glacial melt decreases the rate of North Atlantic Deep Water (NADW) formation because decreased density suppresses convective overturning, leading to density stratification and less salty water dispersing; therefore, ocean salinity declines, rather than localized warming.
