Scientists warn that this weather pattern could disrupt weather, food supplies and economies in the future.
has officially begun and this could potentially bring extreme weather conditions to many parts of the world. The phenomenon is a weather pattern that occurs in the Pacific and pushes up global temperatures.pattern's occurrence wasn't a surprise to forecasters as they expected the warming phase to occur after the cooler "sister" pattern, La Niña, ended earlier this year, many are warning that this event could end up being a "super" El Niño.
With the potential to be one of the strongest ever recorded, and mixing with decades of human-caused warming, forecasters are estimating that it could bring another record-hot year - most likely occurring in 2027. While many people enjoy hotter weather, it could end up disrupting weather,Announcing the weather event, the NOAA said: "El Niño conditions developed over the past month, as shown by above-average sea surface temperatures across the central to eastern equatorial Pacific Ocean.
"Additionally, the agency has seen winds above the equatorial Pacific begin to shift. This is a sign that the atmosphere is now responding to the warmer ocean, not just the ocean warming on its own, according toDuring an El Niño, the ocean will transfer heat to the air, making it warmer. When this is combined with already soaring temperatures across the globe, this makes the atmosphere even hotter.
While conditions are under way, the El Niño - which occurs every two to seven years - is expected to develop later this year. Scientists are now predicting that it is likely that a "very strong" El Niño will occur, which is defined as sea surface temperatures being 2C above average.
The NOAA's June outlook states that "there is a 63 per cent chance of a very strong El Niño during November-January, that would rank among the largest El Niño events in the historical record going back to 1950.
" However, some of the latest models from the US and Europe are warning that this weather phenomenon may go even further, with temperatures in the tropical Pacific potentially going 3C above average by the end of the year. He said: "The current El Niño is… riding on top of a substantial amount of global warming.
This means that the actual temperatures in affected regions could well be unprecedented, as the warming from El Niño is being topped up by climate change.
" Globally the current warmest year on record is the year 2024, which was boosted by an El Niño. However, scientists have warned that the previous weather pattern was not especially strong in comparison to the one that is under way. Professor Scaife adds: "At the end of this year and into 2027, we're likely to see very high temperatures globally.
In 2027, we're likely to see excess heat on top of the global warming we've already got, and that could easily lead to another year above 1.5 degrees .
" Scientists are warning that a strong El Niño could bring a variety of weather extremes, including intense droughts, heavy rainfall, and the increased risk of heatwaves both on land and in the ocean.
