El Nino and Volcanoes

There have been volcanic eruptions throughout the course of history. El Ninos have particularly come as a result of these eruptions, but the effects from the eruptions on the area itself can be disastrous, especially when an overexposure of gas is released with sea temperatures changing drastically. According to an article by the Earth Sky website, Pinatubo-like eruptions have the ability to shorten La Niñas by lengthening El Niños which will, as it's stated, "lead to unusual warming during neutral periods".


An example of volcanos erupting the year is the recent Bali volcano. The eruption has prompted more than 100,000 residents to be evacuated. The Bali volcano has had a history of taking lives, and if it gets worse this year, it will severely damage the economy as well as affect the environment. Flights to Indonesia were also cancelled for safety precautions.

The Washington Post' article states that Mount Pinatubo in the Philippines in 1991 was the largest eruption in about eighty years with the explosion releasing a sulfuric acid aerosol cloud into the atmosphere. The El Niño event in 1992-1993 couldn't change the inevitable outcome as, according to the article, "the cloud spread rapidly around the Earth, covering the entire globe in less than a year, and cooled temperatures by about 1 degree." It's clear to see that despite being in it current state, it will affect climate change in some way.
