El Niño is a recurring climate event with impacts across the globe. It has three phases: one cold (known as La Niña), one neutral, and one warm (El Niño).
In 2026, spring in the northern hemisphere took place in a neutral phase, which followed a relatively mild La Niña. Short-term forecast models indicate that by mid-year it is very likely that we will enter an El Niño phase. This El Niño could become very intense towards the end of the year, with talk of a “super-El Niño”. But what effects might it have? And has something similar happened in the past?
