Points to Ponder

*     How do El Niño events get started?

*     What causes them to stop?

*     Why are some El Niño events larger or different than other El Niño events?

*     What makes each El Niño event's impacts different?

*     What are the basic processes by which they impact the global environment?

*     Why do La Niñas follow El Niño at some times, and not other times?

*     Why does El Niño occur at irregular intervals?

*     Does El Niño cause the climate anomalies or is it just linked to the anomalies?

*     Is the 1976 climate jump linked to the number and intensity of El Niño events after 1976?

*     Why aren't we able to better forecast them and their impacts?
