Which outcome occurs when global glacier melt accelerates?

💡 Explanation

Accelerated glacial melt causes a reduction in water density in polar regions, thus disrupting thermohaline circulation because increased freshwater input overrides salinity gradients, which drive sinking; therefore, ocean current pathways shift, rather than directly influencing upwelling, gyres, or ENSO, which are driven by wind and pressure.
