El Nino and Global Warming: Are They Related?

Many scientists say that there is a correlation between the weather phenomenon El Nino and the problem of global warming. Because of the things that humans are doing to the atmosphere, it is said that the earth is becoming warmer and therefore the intensity of El Nino is growing year by year. At the same time, many scientists disagree with this wholeheartedly. There is good evidence to go either way, so you will just have to read through some of the information here. Ultimately you will decide for yourself whether you think we are causing global warming, and whether global warming is affecting El Nino.

There was some controversy when evidence came up that El Nino might have caused some short-term increases in temperature. This was around the time that the theory of global warming was becoming more popular, and people started to see a scandal. What if global warming wasn’t really true at all, and it was just a product of El Nino? Everyone knows about El Nino, so that would definitely take some of the fear away from the steadily increasing temperatures. There has still been no conclusive proof either way that global warming is a product of humans, so it actually might be a weather pattern that takes years to go through its cycle.

So it is a possibility that El Nino is causing global warming, but what if it was the other way around? Could global warming be causing El Nino to intensify over time? Some believe that this is a perfectly logical theory due to the simple cause and effect. If El Nino is caused by warmth in a certain region, it seems that global warming could cause more warmth and therefore a stronger Nino. This was another theory that was in the public eye for a while, but was quickly disproved by scientists.

Before any truly conclusive answers can be made about global warming and El Nino, years more of weather and temperatures must be analyzed. If global warming is just occurring in the recent past, it will have a much higher rate of increase than if it had been happening without the help of humans. Hopefully with enough data observation, we can begin to decide which of the two cases it is.
