Will volcanic eruption cause the climate to cool down?

When a volcano erupts, it will produce a lot of volcanic ash and various gases, and the atmosphere also contains various gases, but these gases are relatively stable. When a volcano erupts, a large amount of volcanic eruption gas will enter the atmosphere, and in the relatively stable stratosphere, volcanic ash will form aerosol here, which will really cause the climate to cool rather than warm.

Because aerosol has the function of reflecting solar radiation, the function of radiating to the ground is reduced, which leads to the decrease of ground temperature.

An example of climate cooling caused by volcanic eruption

In the past, the weather turned cold instead of warm after volcanic eruption, and with the increase of volcanic eruption intensity, the temperature dropped more seriously.

For example, the eruption of Mount Pinatubo in the Philippines in 199 1 year caused the global temperature to be 0.3 to 0.5 degrees lower than normal. 18 15, Indonesia's Tambora volcano erupted, which led to 18 16, a famous "year without summer" in Europe and North America.
