Today the United Nations World Meteorological Organization (WMO) announced that “for the first time in seven years, El Niño conditions have established in the tropical Pacific, setting the stage for a likely sharp increase in global temperatures and damaging weather and climate patterns.” In early June about the return of El Niño reported US scientists.
El Niño occurs on average once every 2 to 7 years, and episodes typically last 9 to 12 months. This is a naturally occurring climate regime associated with rising ocean surface temperatures in the central and eastern tropical Pacific. But this is happening in the context of a climate altered by human activity.
WMO explained that “there is a 90% chance that El Niño will continue in the second half of 2023. It is expected to be at least moderate in strength. The WMO Bulletin brings together forecasts and advice from experts around the world.”
“The onset of El Niño will greatly increase the likelihood of temperature records and more extreme heat in many parts of the world and ocean regions,” said WMO Secretary-General Professor Petteri Taalas. climate phenomenon are vital to saving lives and livelihoods.”
According to WMO reports, 2016 was the warmest year on record due to the “double whammy” of El Niño and anthropogenic warming caused by greenhouse gases. The impact on global temperatures typically appears within a year of an El Niño event, “so it’s likely to be most noticeable in 2024.”
El Niño events are usually associated with increased rainfall in southern South America, the southern United States, the Horn of Africa, and Central Asia. In contrast, El Niño could cause severe drought in Australia, Indonesia, parts of South Asia, Central America and northern South America. In the summer, warmer water due to El Niño can fuel hurricanes in the central and eastern Pacific Ocean and at the same time prevent the formation of hurricanes in the Atlantic basin.
