← GeographyWhich risk especially intensifies with El Niño-driven currents?
A)Harmful algal bloom proliferation✓
B)Increased coastal erosion rates
C)Accelerated glacier melt rates
D)Strengthened deep ocean upwelling
💡 Explanation
Harmful algal blooms proliferate due to nutrient upwelling stagnation during El Niño events through the mechanism of nutrient stratification, stimulating bloom formation. Therefore, algal blooms, rather than coastal erosion, become extensive because El Niño reduces water mixing.
