The planet's climate could enter a new phase of sharply accelerating global heat. The alarm is being raised by several international weather models that monitor the evolution of El Niño , the natural Pacific phenomenon capable of influencing temperatures, rainfall, droughts, and heat waves worldwide. According to some projections, a Super Niño , a particularly intense version of this climate event, could develop between 2026 and 2027.
To understand the significance of the news, we need to start with the correct name: El Niño , a Spanish term that refers to the anomalous warming of the surface waters of the equatorial Pacific Ocean. When this warming exceeds certain thresholds and lasts several months, the phenomenon alters global atmospheric circulation. Essentially, it changes the way the planet distributes heat and moisture.
A Super Niño is when the intensity is exceptional. In these cases , ocean temperatures rise much more than normal, and the effects can be extreme: prolonged droughts in some areas, torrential rains in others, more frequent wildfires, more violent cyclones, and an increase in average global temperatures.
This is why El Niño is so important for measuring the climate crisis . The phenomenon isn't caused by global warming, because it has always existed as a natural oscillation of the climate system. But today it's acting on a planet already overheated by greenhouse gas emissions. It's like adding an extra engine to a car that's already running too fast.
Scientists closely monitor these events because they demonstrate how fragile Earth's climate has become. When a strong El Niño adds to human-caused warming, heat records become easier to break and extreme events more likely.
2024 was the clearest proof of this. It was the hottest year on record globally, with record average temperatures , exceptionally warm oceans for many months , and numerous extreme events: floods, fires, droughts, and prolonged heat waves across several continents. Italy also experienced long anomalous periods, with increasingly less recognizable seasons and tropical peaks in many cities.
According to experts, the previous El Niño significantly contributed to pushing the global thermometer upward, amplifying the effects of an already ongoing trend. This is a signal that shouldn't be ignored: climate records aren't abstract numbers, but indicators of concrete changes that impact health, agriculture, energy bills, and water availability.
What about 2027 ? If a particularly intense Super Niño were to form, we risk seeing another surge in global temperatures. This could increase the likelihood of scorching summers, longer periods of drought in some Mediterranean regions, extreme rainfall in other areas of the planet, and further stress on already strained ecosystems.
This doesn't mean everything is written in advance. Climate forecasts indicate probabilistic scenarios, not absolute certainties. But the message is clear: the climate is entering a zone of greater instability, and any intense natural phenomenon could have more severe effects than in the past.
The Super Niño, therefore, is more than just a meteorological curiosity. It reflects the Earth's health and reminds us of the urgency of reducing emissions, energy waste, and delays in environmental policies.
