Is climate change strengthening the El Niño phenomenon?

A new scientific debate is taking place among researchers around the world over the impact of climate change on the intensity of the El Niño phenomenon, one of the most important global climate patterns that affects weather across the planet.

El Niño , which occurs every few years and is associated with rising global temperatures, has just begun a new cycle that is expected to last until 2027. According to forecasts, this episode could be among the strongest on record.

Some researchers argue that rising greenhouse gases are “strengthening” these episodes, making El Niños of recent decades more intense than historical records spanning centuries. They point out that this could be linked to changes caused by global warming.

However, another part of the scientific community remains skeptical, stressing that there is still no clear evidence that climate change is necessarily making El Niño stronger. According to them, the phenomenon is very complex and influenced by a number of natural factors in the ocean and atmosphere.

Experts describe El Niño as a complex system that operates through multiple climate interactions, making it difficult to precisely determine the role of global warming in its intensity.

The debate remains open, while scientists emphasize that only data from the coming years will be able to provide a clearer answer to this question with major consequences for weather extremes around the world.
