Other than "numbers go up" it's unclear to me what the consequences are, as I'm not extremely familiar with El Niño events. Hurricanes, maybe?

Those include: hydrology (floods, drought), sea-surface temperatures (hotter or cooler, both of which impact local ecologies and fisheries), storms (weaker hurricane season in the Atlantic, due to high-altitude wind shear, stronger in other areas), and others: economic, fisheries, military, human health, marine life, and specific regional impacts.
