Big El Niños happen when the warm waters from the western Pacific push most strongly eastward. And climate change is making that easier, because temperatures in the normally cool waters along the western coasts of North and South America are rising faster than those in other parts of the oceans. So the extra heat from the west can spread further, which loads the dice in favor of major El Niño events
