Many years later, when people think back to 2022, they will never be able to circumvent the eruption of Tonga volcano that stirred up most of the world.
Originally, people pinned their hopes on 2022, but they did not expect that the beginning would be a "disaster mode".
In the past two days, The Tonga volcano has frequently appeared on the hot list, attracting people's attention.
On January 15, a volcanic eruption occurred on the ocean floor in the island nation of Tonga, located in the southwest pacific ocean.
From the satellite cloud map, it is even more shocking:
How severe is this eruption?
Volcanic ash columns form mushroom clouds with a diameter of 5 km and a height of 20,000 m;
In just one hour, 200,000 eruptions were completed;
The energy of the explosion, equivalent to the energy of the explosion of 1,000 atomic bombs of Hiroshima;
The volcano caused 100,000 people in Tonga to lose contact with the outside world, sonic booms can be heard as far away as Alaska, and Japan on the other side of the Pacific Ocean issued an emergency tsunami warning;
The caliber of this volcano is also beyond people's imagination.
Its power should not be underestimated, and the island of Hong Aha Apay before the eruption of the volcano was like an open wing, circling in the South Pacific;
After the eruption, the entire island was directly destroyed, leaving only sporadic pieces of the island.

Fortunately, the eruption did not cause widespread casualties.
This remains the most shocking and violent volcanic eruption of the century.
Although it is distant news for us, it is a real disaster for the locals.
According to media reports, a Chinese blogger living in Tonga filmed the scene before the disaster and then disappeared.
Ms. Li, who is in Guangzhou, chatted with her husband in Tonga for the last time, staying at 13:01 on the day of the eruption.
On the same day, her husband unusually transferred 3355 yuan to her on WeChat, along with a voice:
"The volcano is erupting, the tsunami is coming, I'm going to the airport."
I was never contacted again.
According to the latest news, the houses on an island in Tonga are almost completely destroyed, and the entire country of Tonga has entered a state of emergency.
Some photos flowing out of the country show that Tonga is suffering from a follow-up disaster brought about by a volcano:
The tsunami arrived and roads were damaged;
There are small islands where all houses were engulfed by the tsunami;
Drinking water is difficult for all households,
Crops have been devastating.
The subsequent impact of volcanic eruptions should not be underestimated.
One is volcanic ash;
According to relevant reports, after the volcanic eruption, a large amount of volcanic ash shrouded the local area, and Tonga had already entered the night at 5 pm;
The main island of Tonga is covered in thick volcanic ash and has been called "a bit like the surface of the moon".
Volcanic ash causes air pollution;
The second is acid rain;
Volcanic eruptions cause excessive concentrations of sulfur dioxide over the Pacific Ocean to enter the clouds, followed by acid rain.
The global impact of the Tonga volcanic eruption is still being assessed, but the possible domino effect of the subsequent occurrence is alarming.
A volcanic eruption occurred in Tonga in the southern hemisphere, which seems very far away and has nothing to do with you and me, the American meteorologist Lorenz said:
"A butterfly in the Amazon flaps its wings occasionally, and maybe in two weeks it will cause a storm in Texas."
Regarding this volcanic eruption, many people on the Internet said that it would cause a "summerless year".
Popular science, what is the "year without summer"?
Refers to the sulphides spewed out by volcanoes, which are converted into sulfate aerosols throughout the atmosphere and block heat radiation from the sun, causing global cooling, causing a large reduction in crop yields, and causing famine disasters.
Historically, in 1815, Mount Tambora in Indonesia erupted, supposedly reaching a magnitude of 7, resulting in a terrifying "summerless year" the following year.
In 1816, in China, there was famine in Yunnan Province, severe frost in Heilongjiang in the northeast, and summer and winter in June and July in Anhui and Jiangxi, full of hunger and death, and tragic phenomena in the world.
Thankfully, the eruption produced about 400,000 tons of sulfide, which is not enough to bring about a "summerless year".

However, the eruption in Tonga will still have a certain impact on the climate.
According to the analysis of the meteorological department:
First of all, the southern part of Australia and southern Brazil in the middle and high latitudes of the southern hemisphere, New Zealand, Argentina, Chile and South Africa bears the brunt of the climate, and there will be short-term cooling, even drought, which will have an impact on crops;
Second, volcanic eruptions may give rise to El Niño, and extreme weather is likely to increase;
Although the volcanic eruption in Tonga has not yet had an impact on the global climate, the reduction in food production caused by local climate change is really related to our lives.
We know that although China is a big food country, our food security still needs to be guaranteed by imports.
From the perspective of the source countries of grain imports from January to November last year, they are mainly distributed in the United States, Brazil, Canada, Argentina, Australia and so on.
If the Tonga volcano has an impact on the climate of the southern hemisphere, then the volcano that occurred in the southern hemisphere may have a crisis for food security this year.
Lu Xun said:
"Infinite distances, countless people, are related to us."
Do not ignore every distant catastrophe, human beings and nature, inherently affect each other, interconnected.
In the past two years, extreme weather has caused many food countries to suffer from food crises, and the new crown epidemic has ravaged the world, which has brought difficulties to production.

In 2021 alone, the world's eight food exporters fell sharply due to extreme weather:
Spring wheat harvests in the United States fell 41 percent from the previous year, a 33-year low;
Canada's spring wheat harvest was reduced by about 30%;
Changes in the quantity of supply have led to an increase in the price of food, an increase in the price of food and a sharp increase in the number of hungry people.
The world is likely to face its worst food crisis in 50 years, with 130 million more hungry people, according to a UNITED Nations study.
And now, of the world's 7.6 billion people, at least 820 million people are hungry, which means that 1 in 9 people go hungry;
We were not born in an era when there was no hunger, but in a country that was feeding on food.
On the other hand, the data on food waste losses on the mainland are staggering.
According to statistics, the mainland wastes about 35 million tons of grain every year, and the wasted grain is close to 6% of the total grain;
Food waste on the table, up to 200 billion yuan a year, the amount of food that is dumped is enough for 200 million people to eat a year;
We thought that without a food crisis, we could waste it.
As everyone knows, just to solve the problem of food and clothing, we have only been in the past few decades.
Thinking of danger in times of peace, thinking is prepared and prepared.
Last November, an official notice came to everyone's attention.
Notice of the Ministry of Commerce:
"Families are encouraged to store a certain amount of necessities as needed to meet the needs of daily life and emergencies."
What is an "emergency"?
Some time ago, the outbreak of the epidemic in Xi'an suddenly, the entire city was locked down, daily life, into a shortage;
In July last year, Henan suddenly fell in a thousand years of torrential rain, the streets were flooded, shops closed, and life was in difficulty.
In recent years, the earth's extreme climate has occurred frequently, which has made unexpected situations more frequent.
This is the "emergency".
Being prepared is probably the best coping we can do.
In addition to being prepared, it is also necessary not to waste.
Usually, you can do the following:
1. Whether it is ordering food, buffet, how much to eat, how much to order;
2. Advocate takeaway to launch small meals, selected according to their own meal volume;
3. Strengthen the management of temporary food and reduce expired waste;
……
Click [Watching], share it with more people, don't think that the distant world has nothing to do with us;
The boundless future, the infinite future, and the countless people are closely related to our current behavior.
