Liputan6.com, New York City – Volcanic ash and other particles continue to burst from Mount Agung. The dangerous cloud caused thousands of residents to be evacuated and many flights had to be canceled.
More recently, experts have warned that the eruption of Mount Agung could affect global life and there is a possibility that the Earth's temperature has decreased for five years. So quoted from page Express.co.uk, Saturday (2/12/2017).
Some of them also believe that it can slow the rate of global warming, due to decreasing the temperature of the Earth.
Scientists have long known that volcanic eruptions could change the Earth's climate, as happened when Tambora erupted in 1815.
However, the occurrence of the phenomenon depends on how terrible the volcano erupted. It was delivered by NASA climate scientist, Chris Colose.
"In order for the climate impact to be significant, there needs to be a fairly explosive eruption (to send volcanic material to the stratosphere) and sulfur dioxide-rich eruptions turning it into sulfuric acid that can block the sun's rays," Colose said.
"If this condition is met, the eruption will cool the surface or troposphere and warm the stratosphere, the opposite of both patterns associated with increased carbon dioxide, but both are very short-lived," he added.
In 1963, the eruption of Mount Agung reached a height of 26 kilometers above sea level and killed about 1110 people. It is not surprising that the eruptions contribute to Earth's temperature drop, although not significantly.
"To be able to influence the climate, it needs a considerable amount of sulfur dioxide to enter the stratosphere," said Colose, "sulfur dioxide particles can block the sun's incoming rays, thus cooling the planet."
"If a similar sulfur dioxide release occurs, it can cool the planet for 1-2 years, and then go back to normal," he added.
Scientists say Mount Mount Agung's latest eruptive behavior is similar to the 1963 eruption. They estimate that similar amounts of sulfur dioxide may be released into the atmosphere.The eruption of Mount Agung in 1963 lowered the global temperature by 0.2 degrees Celsius for one year. However, if the same amount of sulfur dioxide is vomited into the Earth's atmosphere in the latest eruption, the global temperature will fall by 0.1 to 0.2 degrees Celsius in the period 2018 to 2020.
An environmental science scientist at Rutgers University, Alan Robock, says that sulfur dioxide that reacts with water in the atmosphere will form sulfuric acid droplets that can last for more than a year.
When the sun's rays touch the droplets, energy is reflected back into space, reducing the entry of the Sun's rays in large quantities.
