自2023年6月厄尔尼诺现象回归以来，每个月都创下了新的高温纪录，使得2023年成为有气象记录以来全球最热的一年。本次厄尔尼诺现象在去年12月达到顶峰，是有记录以来最强的五次之一。① The World Meteorological Organization (WMO), a United Nations agency, released a report saying that the El Niño phenomenon, which began last year, is expected to end this year, and the La Niña phenomenon is likely to occur thereafter, which will lower the global temperature; ② The World Meteorological Organization also emphasized that due to climate change caused by human activities, global temperatures will continue to rise over the long term.
Finance Association, June 4 (Editor Xia Junxiong) On Monday (June 3) local time, the United Nations agency World Meteorological Organization (WMO) released a report saying that the El Niño phenomenon, which began last year, is expected to end this year, followed by the La Niña phenomenon, which will lower global temperatures.
However, the World Meteorological Organization also emphasized that global temperatures will continue to rise over the long term due to climate change caused by human activities.
Since the return of the El Niño phenomenon in June 2023, new high temperature records have been set every month, making 2023 the hottest year in the world since meteorological records were recorded. The current El Niño phenomenon peaked in December of last year, one of the five strongest on record.
Earlier this year, the US National Oceanic and Atmospheric Administration (NOAA) warned that this year was 1/3 likely to be hotter than 2023.
However, according to the latest report from the World Meteorological Organization, the probability of a La Niña phenomenon from July to September is 60%, and the probability of a La Niña event occurring from August to November is 70%, so the possibility of an El Niño event happening again is negligible.
The El Niño phenomenon causes heavy rainfall and increased dry weather. Floods may occur in areas that are usually arid and have little rain, while droughts may occur in some rainy regions. Prices of soft commodities such as coffee, cocoa, and orange juice have soared sharply this year due to extreme weather caused by the El Niño phenomenon.
The characteristics of the La Niña phenomenon are the opposite of El Niño. It usually makes the climate in some US states and South America more arid than usual, causes rainfall in regions such as Australia, Indonesia, and Central America to exceed normal periods, and also increases the possibility of a Pacific tropical cyclone.
Prior to the El Niño phenomenon last year, there was a La Niña phenomenon around the world for three consecutive years, which benefited agricultural production in Australia. Australia is the world's second-largest wheat exporter. Thanks to abundant precipitation brought about by the La Niña phenomenon, the country's wheat exports reached 28 million tons in 2022 - 2023, the highest in history.
