Which disruptive effect arises from upwelling's sudden reduction?

💡 Explanation

Reduced upwelling limits nutrient supply, which reduces phytoplankton, therefore less carbon dioxide is absorbed from the atmosphere because the biological pump weakens. It is oceanic sequestration rather than coastal erosion driven by waves.
