Quick Summary of the Key Information
The core message of this warning report is clear: In the second half of 2026, the tropical Pacific is experiencing the strongest El Niño event on record since modern meteorological observations began. The abnormal rise in sea temperatures has broken all monitoring records from the past 70 years, and its destructive effects are expected to last at least until the spring of 2027. This will not only make 2027 the hottest year on record but will also impact the global economy across various sectors, including shipping, agriculture, fisheries, and energy. China will specifically face a range of climatic challenges such as flooding in the south and drought in the north, an increase in typhoons, and milder winters. Many countries around the world have already entered a state of emergency response.

Detailed Analysis
1. El Niño: A “Cute Baby” by Name, but a Climate Monster in Reality
Many people have heard of El Niño but don’t really understand what it is. There’s no need to memorize technical terms like “atmospheric-sea coupling” or “Walker Circulation.” Imagine the tropical Pacific as a giant bathtub containing trillions of tons of water. Under normal circumstances, the eastward winds above the equator blow the warm surface water towards the west, causing a thick layer of warm water to accumulate in the western regions, such as Southeast Asia and Australia, and raising the sea level by half a meter compared to the eastern coasts of South America. When the warm water in the east is blown away, the cold, nutrient-rich water from the bottom rises, creating the world’s most productive fishing grounds in Peru. This balance is disrupted every 2-7 years: the eastward winds suddenly weaken or reverse, allowing the warm water from the west to surge eastward, forming a thick “thermal blanket” over the central and eastern Pacific. This disrupts the global weather system, leading to extreme weather patterns.
2. Why Is This Year’s El Niño Such a Concern for Scientists?
Previously, there have been two recognized “century-scale” El Niños: in 1982-1983, sea temperatures were 1.5°C above average, and in 1997-1998, they were less than 2°C above average, causing tens of thousands of deaths and billions of dollars in economic losses. This year’s El Niño has broken all records, with surface sea temperatures rising by more than 2°C in some areas and even approaching 4°C in others. More alarming is that the deep water temperatures have increased by 8°C compared to the same period in previous years, as if a huge boiler is heating the ocean continuously, with no sign of cooling down. Given that the Earth is already on a path of global warming, this super El Niño is releasing decades of accumulated heat into the atmosphere, potentially making 2027 the hottest year on record.
3. The Economic Impacts of El Niño
El Niño’s effects are not limited to the weather; they also have a direct impact on the economy. For example, shipping costs have increased by 30% in the past half-month due to the reduced water levels in the Panama Canal. Global food and energy prices are expected to rise, as the disruption of fishing and agricultural production will affect supply chains. Historical data shows that the 1997-1998 El Niño resulted in global losses of $5.7 trillion (about 40 trillion yuan), exceeding the total annual consumption of China in 2023.
4. Consequences for Ordinary People in China
As an East Asian country, China will not be immune to the impacts of El Niño. However, there are preparedness measures in place. Here are some key trends to expect:
- More typhoons are expected to hit the southeastern coast this year, with increased destructive power.
- There will likely be flooding in the south and drought in the north.
- This winter is likely to be milder, but it may also lead to increased pest infestations due to the lack of cold air from Siberia.
- The government has already implemented plans to mitigate the effects, such as enhancing weather warnings and water management systems.
5. The Lesson from El Niño
El Niño highlights the vulnerability of vulnerable communities around the world. While modern technology has reduced the potential for catastrophic outcomes like famines, many developing countries still lack essential infrastructure, making them more susceptible to disasters. Addressing these underlying issues—such as improved water management, drainage systems, and fire prevention—will help countries better prepare for and cope with extreme weather events. By reducing carbon emissions, we can also mitigate the frequency and severity of such events in the future.
