Which effect increases in global coastal areas as the frequency of El Niño events rises?

💡 Explanation

When El Niño events increase, changes disrupt normal wind and ocean current patterns, leading to reduced rainfall in some coastal regions and increased sea levels due to thermal expansion, which increases hydrostatic pressure. Therefore saltwater intrusion risk rises, rather than upwelling, forest expansion, or isolated bleaching episodes which show different, often indirectly linked, causal patterns.

• Which risk increases when extensive vegetation removal occurs on river levees?
• Which outcome occurs when carbonic acid concentration increases?
• Which risk increases when an oceanic plate subducts beneath a continental plate with high sediment cover?
• Which risk increases when warming temperatures degrade permafrost beneath Arctic infrastructure supports?
• Which geologic outcome intensifies when an oceanic plate subducts at a steeper angle beneath a continental plate?
• Which outcome is amplified with increased Rossby effect magnitude?
