What do you still wonder about El Niño and air temperature?

One question that I still wonder about is how exactly El Niño events impact air temperatures in different regions around the world. It is known that El Niño can lead to warmer-than-average temperatures in some areas and cooler-than-average temperatures in others, but the mechanisms and specific patterns of these temperature changes are still not completely understood. Additionally, I am curious about the potential long-term effects of climate change on the frequency and intensity of El Niño events, and how this may in turn influence global air temperatures.
