Events of El Niño do not happen because of climate change; these are a natural phenomenon that has been happening for thousands of years. Scientists have a theory that it may be becoming worse as a result to climate change, but it is not yet 100% clear looking at how El Niño communicates with the change of climate. In terms of intense events of weather, climate change is most likely to affect the El Niño and La Niña impact.
Unfortunately, we cannot prevent El Niño and La Niña from happening. Since they are a natural phenomenon that occurs from climate patterns, humans would not be able to do anything as they cannot influence its duration or longevity.
Natural cycles of weather
As human beings contribute more and more gases, which traps the heat onto the atmosphere, the Earth gets warm. And this warming is going to cause something bigger, which might surprise us. Not only is the weather becoming more changeable, but warming is also causing intense heat, high sea level, loss of ice, and many more. Alternatively, it is making natural cycles of weather more compelling.
As the case may be, the most important natural change in the climate of the Earth is the process of El Niño. It is defined as the warm ocean surface temperatures in the Pacific for a short period of time. If La Niña happens, that region is colder than usual, while if El Niño occurs, the region will be warmer than usual. At times, if El Niño or La Niña is present and its waters are at a normal temperature-this is called a "neutral" stage.
Pattern of oscillation
Between El Niño and La Niña, the waters of the ocean start to switch back and forth every few years. It is like a pendulum, it does not happen often, but a pattern of oscillation is seen. And whether the cycle of El Niño and La Niña is present, there will be consequences around the world for this weather. For example, during the cycle of El Niño, we usually witness hotter and drier weather in South America and Australia while it is cooler and wetter in the south of the United States.
It is very important to be able to distinguish ahead of time the cycles of El Niño and La Niña. It is also important to comprehend how these cycles will change on the planet Earth. Cycles of El Niño have been known for a long time now. Its influence has also been known for almost 100 years around the globe. In 1920, the El Niño impact was discovered in places like the Indian Ocean, which is very far away. Scientists were known to have an aspect that something might start changing while observing the effects of El Niño for a century now.
