Xu Hao didn't notice that the weather has been very low this year, and it was supposed to be planted in March, but because the low temperature became April, this is still in Yuzhang County in the south.

And it was supposed to be in the autumn harvest in September, but the whole Daqi was swept by a cold air, first it snowed in the north, and then the whole south also began to snow, this heavy snow made the entire north harvest, and the grain in the south was also reduced by more than half, and what was even more terrifying was that it snowed in September this year, and the temperature dropped directly to more than ten degrees below zero!

Xu Hao was even more shocked when he used a reconnaissance satellite to check the situation in the north, because the thousands of miles of rivers and mountains in the north have become white, and traces of human activities can still be seen in some big cities.

"What's going on, how did the climate of Daqi become an ice age!" Xu Hao felt a little wrong at this time.

At this time, he remembered that last year's winter not only came early, but also very cold, and this summer was not too high in temperature, but after Xu Hao became a monk, even if he didn't use mana, it reached the point where the cold and heat would not invade, and he had been busy with the matter of the dead soul, so he didn't pay attention to this matter, and now the weather was so cold that even a monk like him could feel it, and he realized that something was wrong.

But how can this extreme weather not even have a transitional period, even if it is the Xiaoice period, there should be a period of several hundred years, how can there be an extreme situation of sudden changes in two years!

And when Xu Hao was thinking, Hongyuan found him and said, "Xu Hao, your family can't get a lot of cotton clothes?" ”

Xu Hao saw Hongyuan and said: "Our Qingniuguan cotton clothes are insufficient? ”

Hongyuan nodded and said: "There are not many disciples on the mountain, but there are more than 100,000 people who rely on our Qingniuguan to eat, and last time the local dart bureau and martial arts hall in Yuzhang County also took refuge in us, and now they lack cold things and find us, now the weather is suddenly cold, everyone can't bear it, the entire Yuzhang County cloth, cotton clothes, cotton, and even fuel have risen 10 times for more than that, we Qingniuguan and textile factories are making every effort to produce cotton clothes and quilts, but this amount is a drop in the bucket, not to mention that now even cotton can't be obtained." , the textile mill is also weak. ”

Then Hongyuan sighed and said: "Actually, tens of thousands of people have frozen to death in the entire Yuzhang County in the past few days, our Yuzhang County is still a rich county after all, and the people who have frozen to death in other places are even more unimaginable!" This year's snow is too big, the weather is too cold, the teacher has never seen such a big snow, such a cold weather in Yuzhang County! The people of the world have been really difficult all these years, and the disasters have come one after another, and they don't let people breathe at all! ”

Xu Hao said: "I'll find a way!" ”

What else can be done can only go to modern times to buy, Yuzhang County is located in the south, there is very little snow, everyone is not prepared for such a cold weather, if there is no cold materials, how many millions of people in Yuzhang County can live, Xu Hao can't imagine.

There may be hundreds of thousands of sets of cotton clothes, but the quilts are not enough, and there may be millions of sets, but I don't know if the country can prepare well?

Xu Hao launched a crossing, and immediately found an expert and said: "Trouble the country to help prepare millions of sets of cotton clothes and quilts!" ”

The expert was surprised: "What happened? ”

Xu Hao smiled bitterly: "The Great Qi world has suddenly entered an ice age, and now the temperature in the north has dropped to minus 30 degrees, even Yuzhang County in the south has more than 10 degrees below zero!" ”

The expert was surprised: "How could there be such extreme weather, I think the world of Daqi is warmer than our world!" There are no signs of an ice age at all! You tell me what happened during this time! ”

So Xu Hao put the righteous demon war, the underworld was destroyed, thousands of souls were released, and then the heavenly way was revealed, the heavens punished the mastermind, and used the small world of the Kunlun faction as a new pure land to settle the souls of the world, and finally Xu Hao said the most insignificant thing, that is, the volcanic eruption in Youzhou, and the flat land created an active volcano thousands of meters high!

The expert didn't understand much before, but he heard an active volcano sigh and said: "Xu Hao, you have ended more than ten years of education in modern times, and the knowledge of geographical advantages has been exchanged for the teacher, and an active volcano has been erupting, and you haven't found a way to extinguish it!" ”

No matter how idiotic Xu Hao is, he knows that Daqi's current situation should be related to this active volcano, and he asked carefully: "The volcano is too big, with a diameter of more than 10 kilometers, I don't have this ability at all!" ”

"The crater is 10 km away! If your world is not saved, you will flee to the equator with the people of Qingniuguan, and maybe you can still keep the seeds of civilization revival! ”

"About 250 million years ago, the earth ushered in the largest mass extinction in history, with more than 95% of biological species extinct and disappeared during this period.

The cause of this massive extinction was the eruption of the mantle plume, and scientists predicted that in the late Permian, all the landmasses were squeezed together due to plate movements, forming the Pangea supercontinent. At the same time, however, volcanic activity and disasters such as earthquakes caused the land to be separated again. The main culprit that led to the separation of the Pangea supercontinent was the eruption of the super mantle plume, when hundreds of millions of tons of volcanic ash entered the stratosphere to block the sun, leaving the earth without sun irradiation for decades, and the entire earth became a frozen planet, and the earth's life almost died. ”

"Now the Youzhou volcano you are talking about is definitely not as strong as the Permian, but listening to your words, it has been erupting for more than a year, and you still don't pay attention to it completely, think about it, the stratospheric volcanic ash in Daqi is not tens of millions of tons, but it should be millions of tons, do you know what this means?

If a volcano is compared to a burning boiler, then volcanic ash is like smoke and dust in a chimney, in fact, the earth produces more than a billion tons of smoke and dust every year, but as long as the problem in the troposphere is not big, at most it is just pollution, everyone can control it.

However, as long as the volcanic ash is sprayed thousands or even tens of thousands of meters above the surface of the earth in one breath, and enters the stratosphere, the problem will be serious.

The stratosphere is hot and cold, the air is thin, and there is very little water vapor, so there are almost no weather changes such as thunder, rain, and wind in the atmosphere in this layer, and the air convection is very weak, and the volcanic ash itself is very light, so it is difficult for the volcanic ash that breaks into the stratosphere to be carried away by rain and air currents in the short term.

The huge amount of volcanic ash ejected from the ground will form a super parasol in the atmosphere, blocking out the light and heat released by the sun to the entire planet, resulting in cold weather. ”
