World Meteorological Organization warning! El Ni ñ o may lead to record breaking temperatures in the future | El Ni ñ o | World Meteorological Organization
The World Meteorological Organization said on the 4th that the tropical Pacific region has formed an El Ni ñ o condition for the first time in 7 years, and it is expected that temperatures in most parts of the world will further rise in the future. Record high temperatures may occur within 5 years, and governments around the world should be prepared to respond to related climate events.
The El Ni ñ o phenomenon is a naturally occurring climate pattern associated with warming ocean surface temperatures in the central and eastern tropical Pacific. It occurs on average every 2 to 7 years and typically lasts for 9 to 12 months. The World Meteorological Organization predicts that the likelihood of an El Ni ñ o event continuing in the second half of 2023 is 90%.
On the 8th of last month, the National Oceanic and Atmospheric Administration of the United States issued an alert stating that the El Ni ñ o phenomenon has already occurred and is expected to continue into winter, possibly developing into a moderate or strong El Ni ñ o. The World Meteorological Organization predicts that the intensity of this El Ni ñ o phenomenon will be at least moderate.
This organization emphasizes that the impact of El Ni ñ o on global temperatures is usually most pronounced in the year following its onset, this time in 2024. The Secretary General of the World Meteorological Organization, Petri Taras, said that the occurrence of El Ni ñ o will greatly increase the likelihood of breaking temperature records, "triggering more extreme heat in multiple regions and oceans around the world.".
The World Meteorological Organization mentioned in its latest announcement a report released in May, which predicted that at least one year from 2023 to 2027 would break the high temperature record set in 2016, with a probability of 98%. The head of the regional meteorological forecasting service department of this organization, Mufuma Okia, said at a press conference that in the next five years, "we may experience the hottest year on record.".
According to the Global Climate Status report released by the World Meteorological Organization, 2016 was the hottest year on record due to the dual impact of the strong El Ni ñ o phenomenon and human greenhouse gas emissions.
This year's El Ni ñ o phenomenon is even more complex. The La Ni ñ a phenomenon has been ongoing for nearly three years from the summer of 2020 to early spring of 2023. The La Ni ñ a phenomenon is opposite to the El Ni ñ o phenomenon, which is an abnormal decrease in water temperature in the central eastern Pacific equator. Some meteorological experts pointed out that extreme weather events such as rainstorm are likely to occur during the transition from La Nina to El Nino.
The World Meteorological Organization reminds in its latest report that the El Ni ñ o phenomenon usually leads to increased rainfall in southern South America, the Horn of Africa, parts of Central Asia, and other regions. It can also cause severe drought in Australia, Indonesia, and parts of South Asia.
Taras said that announcing the occurrence of the El Ni ñ o phenomenon "sends a signal to governments around the world" and should be mobilized as soon as possible and prepared in advance to reduce the impact of this phenomenon on people's health, ecosystems, and economies of various countries.
