Explainer: How the ‘super El Niño’ will reshape the world’s weather

The world is currently experiencing what is expected to become the strongest El Niño on record – dubbed a “super El Niño” by many.

In 1963, WHOI biologist Dick Backus set his sights on a question that had puzzled scientists for decades: what caused the daily vertical movement of plankton? The sun or an internal clock? During an eclipse, Backus was able to monitor that the migration was triggered by changing light levels!
