It’s rather hot lately. And last month South Asia suffered from a heat wave. Vietnam currently has record highs of 44,1°C.
It seems very likely that we will be dealing with the El Niño weather phenomenon this year, which may be accompanied by new high temperature records. That message comes from the World Meteorological Organization (WMO) of the United Nations (UN). The WMO estimates the chance of experiencing El Niño at the end of July at 60% and at the end of September at 80%.
El Niño is a natural phenomenon typically associated with rising temperatures, increasing drought in certain parts of the world, and heavy rainfall in others. It is responsible for a periodic warming of the ocean waters, which causes the earth to warm up. The phenomenon occurs on average every two to seven years, for an average period of nine to twelve months. The phenomenon typically causes increased rainfall in parts of South America, the southern United States, the Horn of Africa and Central Asia, and extreme drought in Australia, Indonesia and certain parts of South Asia. The most recent time the weather phenomenon hit was in 2018-2019. Then it gave way to a remarkably long period of La Niña, which does the opposite and has a cooling effect.
It is not possible at this stage to predict the intensity or duration of El Niño. The previous episode of the phenomenon was considered rather weak, but the one before that - between 2014 and 2016 - was particularly powerful and had disastrous consequences. For example, 2016 was “the warmest year on record due to ‘the dual effect’ of a very strong El Niño and warming caused by greenhouse gases related to human activity,” the WMO points out. The impact of El Niño is usually only felt in the year following the occurrence of the phenomenon, in this case 2024. “The world must prepare”, according to the meteorological organization.
