How do volcanoes affect the climate?

As volcanoes erupt, they emit a mixture of gas and particles into the air. Some of them, such as ash and sulfur dioxide, have a cooling effect as they reflect the sunlight (or the substances they cause) away from the earth. Others such as carbon dioxide cause global warming by increasing the greenhouse effect

The effect of cooling is particularly noticeable, and a large explosion can sunburn particles to the stratosphere. It is difficult to judge that the cooling observed after a specific eruption is definitely the result of an explosion, but checking the global average temperature change after multiple eruptions proves strong ties.

Regarding greenhouse gases, according to estimates of the UK Geological Survey and the US Geological Survey, carbon dioxide totaling about 100 to 300 million tons annually is released from underwater and athletic volcanoes. This is massive, but it is only about 1% of the amount of fossil fuel released only by humans.

Normally, immediately after a volcanic eruption, the cooling effect of a single volcano will dominate, but the effect of global warming will last for a long time. Therefore, the importance of each depends on the time frame considered. In very large volcanoes in 2011, there is a possibility that the temperature has drastically decreased in 2012, but in 2100 it warmed slightly

It is suggested that people trying to argue against human climate impact believe that volcanoes emit carbon dioxide rather than humans. This is totally wrong. As the UK Geological Survey said:

"The current contribution to the carbon dioxide load in the atmosphere by volcanic eruption is relatively small ..."

The long-term impact of volcanoes arises from a simple geographical location. Because the volcano is a huge mountain, the impact on the climate is the same as that of a normal mountain. This leads to a rain shadow effect (explained in the Continental Movement section) that functions like a volcanic building. Until the volcano erodes it will continue to affect the climate. This may last thousands of years. Volcano has a big impact on climate. This effect is either short term (volcanic ash) or long term (rain shadow effect). Biology can also be affected by this. For example, the desert area may develop rapidly on the leew side of a new volcano. Extinction will be a big threat if you can not adjust your life

In 1783, Benjamin Franklin initially assumed that major volcanic eruptions will affect climate after the eruption of Raki volcano in Iceland. Ironically, since most of the material spewed by this eruption remains at the bottom of the atmosphere, Franklin has the right idea, but the volcano is wrong. In the top four panels, Figure 1 shows the effect of four low-latitude volcanic eruptions on global average temperatures between the 1880s and the 1980s. Individual volcanic eruptions show a lot of change in cooling time (although volcanic eruptions occurred at different times of the year), the four volumetric eruptions indicated as "complex" in the fifth group The average of the volcano shows many months in the next three years (especially cold summer)

A volcanic eruption is a geological event that has influenced global explosions for years. Scientists estimate that such last eruption took place 74, 000 years ago, and it is ten thousand times stronger than Mount St. Helens. Large amounts of rocks and ashes were blown into the air causing six years of winter volcanoes and 1000 years of ice age, massive deforestation, devastating famine, and human extinction. Scientists estimate that super eruptions will occur every 100,000 years.
