Effect of volcanic eruption phenomenon

A recent study has shown that volcanic eruptions may help reduce the effects of global warming.

According to scientists, global warming between 2000 and 2010 was not as fast as they perceived because of the chemical compounds erupted during volcanic eruptions around the globe.

When sulfur dioxide gas, generated during volcanic eruption, flies up to the stratosphere, it will participate in a chemical reaction process, forming molecules, capable of reflecting sunlight. Go back to space, instead of allowing it to project directly on Earth. This is the reason why global warming is somewhat limited.

Scientists have observed the rise of these 'Sun-dispersing' molecules between 2000 and 2010. Several studies show that emissions from developing countries in Europe are Asia, like India and China, has partly increased the amount of sulfur dioxide by 60% in a decade, mainly due to coal burning. However, there are a few studies that show that volcanism is an important cause of the increase in sulfur dioxide levels.

Using computers to compare changes in the stratosphere under the influence of coal burning in Asia and volcanic eruptions worldwide in the years 2000 to 2010, scientists have In conclusion, the phenomenon of volcanic eruption is the cause of increasing atmospheric molecules.

Volcanic eruptions help reduce the speed of global warming.

'This study shows that emissions from small- scale volcanic eruptions have helped slow the warming of the Earth , ' said Ryan Neely, who carried out the study as part of his doctoral thesis. I am at Colorada University, Boulder said.

'This finding shows that scientists need to focus on studying volcanic eruptions when studying climate change. However, long-lived volcanoes are unable to balance the warming of the Earth by emissions from volcanic activity sometimes up and down, while emissions emit a greenhouse effect from the Human activity only increases , 'said Brian Toon, Professor at the University of Colorado.

According to Professor Toon, the activities of large volcanoes have a significant impact on the ability to 'cool' global temperatures , such as Mount Pinatubo in the Philippines, erupting in 1991, with an amount of sulfur dioxide released into the aquifer. save enough to make the Earth reduce 0.55 degrees Celsius and 'cool' the Earth within 2 years.
