The 2023–2024 El Niño event was declared on July 4, 2023, by the World Meteorological Organization (WMO), marking the beginning of a significant El Niño–Southern Oscillation event. This event is regarded as the fifth-most powerful in recorded history, with widespread droughts, flooding, and other natural disasters expected to occur across the globe.
The onset of the 2023–2024 El Niño event is expected to have far-reaching consequences, with the most significant meteorological effects anticipated to occur between November 2023 and April 2024. The characteristics of these effects will vary depending on the territory, with droughts, heavy rains, wildfires, heat waves, tropical cyclones, flooding, and changes in wind patterns all possible. As a result, the economic activities of agriculture and fishing are likely to be negatively affected, leading to shortages and rising prices of food, particularly rice, palm oil, sugar cane, soybeans, and corn.
The impact of the 2023–2024 El Niño event on food security is a major concern, with the most vulnerable populations likely to be disproportionately affected. The increase in food prices and shortages will exacerbate existing food insecurity issues, making it essential for governments and international organizations to monitor the situation closely and provide support to those in need. The effects of the El Niño event on agriculture and fishing will also have significant economic implications, with potential losses to industries and communities that rely on these sectors.
Climate scientists have noted that the 2023–2024 El Niño event is being exacerbated by the climate change crisis. As a result, the event is likely to contribute to a rise in average global temperatures, potentially exceeding the record set in 2016 during the 2014–2016 El Niño event. This increase in temperature will have significant implications for the environment, with potential consequences including more frequent and severe heat waves, droughts, and other extreme weather events.
The World Meteorological Organization’s declaration of the 2023–2024 El Niño event serves as a reminder of the importance of monitoring and preparing for significant weather events. By understanding the potential consequences of the El Niño event, governments, international organizations, and communities can take steps to mitigate its effects and provide support to those who will be most affected. As the event progresses, it will be essential to continue monitoring the situation and providing updates on the expected impacts and consequences.
Looking ahead, the next few months will be critical in determining the full extent of the 2023–2024 El Niño event’s impacts. As the most significant meteorological effects are expected to occur between November 2023 and April 2024, it is essential to continue monitoring the situation and providing support to those in need. The potential for the event to contribute to a rise in average global temperatures and exceed the 1.5 °C increase since pre-industrial times will also be closely watched, with significant implications for the environment and global climate. As the situation continues to unfold, it will be essential to stay informed and up-to-date on the latest developments and expected impacts of the 2023–2024 El Niño event.
