The UN has warned that El Niño could soon fuel extreme weather, with reports indicating it is forming in the Pacific and expected to strengthen rapidly. This development is likely to have significant impacts on already vulnerable regions, potentially leading to climate shocks and extreme weather events. The World Meteorological Organization and other experts are advising preparation for the potential consequences of El Niño, although the timing and specifics of its effects, such as when Europe may be affected, are not yet clear.
