"Beware" 2022 may become the year without a summer

The impact of the "Tonga volcano eruption" on climate.

Since entering 2022, the largest natural disaster affecting climate change is the volcanic eruption of Tonga, an island country in the South Pacific.

There are about 50 volcanic eruptions around the world every year, but only once in decades can volcanic ash rising into the sky be photographed from satellites like the Tonga volcano.

Judging from the images returned by weather satellites, the Tonga volcano erupted with great power. The mushroom cloud rising into the sky was quite spectacular, and its impact may spread to the entire Pacific coast.

The most vocal concern is about the impact of the Tonga volcano eruption on global temperatures. Some people even speculate that 2022 will become a year without summer. Is this really going to happen? Is this possible?

There is no precedent in history for the disappearance of summer due to volcanic eruptions

Don’t ignore this seemingly nonsense conjecture, because the inference that volcanic eruptions caused the disappearance of summer is not It's groundless, and there's even precedent.

In 1816, in Europe, America and other regions, the temperature dropped sharply. It was supposed to be a sweltering summer, and there were even snowflakes in some places.

Not only that, there were low-temperature weather all over the world that year. The sudden low temperature caused a large number of crops to freeze to death, and farmers who relied on the weather were helpless.

After the eruption of the Tonga volcano, many regions around the world, including Japan and the United States, issued tsunami warnings. The island countries surrounding the Tonga volcano have even experienced communication interruptions and lost contact with the outside world.

As of now, there are more than 2,500 proven volcanoes in the world, including more than 2,000 "extinct volcanoes" and only 523 active volcanoes.

Although there are not many volcanoes on earth that are capable of erupting, the impact of volcanic eruptions on the earth's environment cannot be taken lightly.

What level does this volcano belong to? Zhang Yuheng, a member of the Stone Science Popularization Studio of the University of Science and Technology of China and currently pursuing a doctoral degree at Texas A&M University in the United States, said that there are a series of rating standards for the intensity of volcanic eruptions. The most commonly used one is the Volcanic Explosive Index (VEI), which was proposed by American scientists in 1982. This index is judged according to the flow rate of the ejecta, and is divided into levels from 0 to 8, corresponding to the ejection flow rate from 0.00001 cubic kilometers to 1,000 cubic kilometers. For each additional level, the ejection volume increases tenfold. Or it can be divided into several levels of experience, from the mildest to the most violent, Hawaiian, Strompolitan, Vulcaninian, Pellenic, Plinian and Super-Plinian.
