Chapter 535 Extreme Weather 2
Although 2021 is not over yet, Wu Siyuan, who has the ability to "foresee the future", knows how abnormal the climate of this year is.

The first one to visit is 【Extreme Low Temperature】.

From the end of 2020 to the beginning of 2021, the overlord-level cold wave will invade Huaguo.

The temperature in many areas dropped by 16 degrees, and even provinces like Yue Province, which has four seasons and Changchun, have issued low temperature orange or even red warnings in many areas.

This extreme cold lasted for more than a whole month, allowing the entire northern hemisphere to see the power of the arctic cold current, causing huge economic losses to China.

Not long after the severe cold passed, [extreme drought] came to visit again.

At the end of February 2021, just after the extreme low temperature phenomenon ended, many areas in the northern hemisphere encountered extreme drought.

First, in March, TW Province encountered the phenomenon of [extreme drought], and the water volume of Sun Moon Lake was almost dry, and the water content of the reservoirs in the entire TW Province was less than 3%.

In addition, Eastern European countries, the capital region of Russia, the Middle East, and North America and Mexico have all suffered severe droughts. Lake Queteo in Mexico has almost completely dried up, which has seriously affected the lives of local residents and caused economic losses. The loss is only on top of the cold snap.

【Extreme Drought】weather barely subsides, but what follows is 【Extreme High Temperature】weather!
Since June, the Moscow region has encountered the highest temperature in the past century, and then the high temperature has swept across the Middle East. The surface temperature in Kuwait even reached a terrifying 6 degrees-it only takes 70 degrees to boil water, and the high temperature of 100 degrees , put a raw egg on the ground, it will be cooked in a short time.

In addition, the "hot dome phenomenon" appeared in North America, which aroused international heated discussions at that time.

[Hot dome phenomenon] refers to the stagnation of thermal high pressure in the upper atmosphere for a period of time, and the atmospheric circulation between the high pressure and the nearby low pressure forms a stable Ω shape.The high pressure is like a hood, which not only covers the hot air in the heat wave area, but also prevents the cold air from entering, making the temperature in the heat dome higher and higher, thus triggering heat waves and even super heat wave events.

In the Maple Leaf Country, which was at a high latitude in the past, the summer temperature was only about 30 degrees. However, in the summer of 2021, it was uncharacteristically, and the average temperature of the Maple Leaf Country reached over 40 degrees.

According to news reports, more than [-] people died from the heat during the week of the highest temperature in Maple Leaf Country.

Along with [extreme high temperature] weather comes [extreme heavy rain] weather.

While countries such as Maple Leaf Country, Pretty Country, and Mexico in North America are experiencing the [Hot Dome Phenomenon], Huaguo is experiencing [Extreme Heavy Rain].

In one hour of the peak rainfall in Shangcheng City, the total rainfall is equivalent to the water storage capacity of 130 West Lakes. At the end of July 2021, the heavy rain in Yu Province, Huaguo, submerged most of the entire Yu Province in the torrent, causing The economic loss is as high as hundreds of billions of dollars.

These four extreme climates are just a microcosm of many natural disasters in 2021. In addition, there are many natural disasters, such as high temperatures in the Arctic and floods in deserts.

On July 7, floods also occurred in the Taklamakan Desert in Huaguo.

The desert has flooded!
Yes, you are not mistaken!
The Taklimakan Desert in the hinterland of New Province is the driest area in the country, with an annual rainfall of only a few tens of millimeters. In the case of extreme water shortage, thousands of square kilometers of land, not to mention people and even animals, can only See the endless yellow sand.

In July 2021, the Taklamakan Desert ushered in an unprecedented record-setting flood. This 7 square kilometers of land was full of water, and the desert turned into a lake. Fortunately, the desert was deserted. Unlike Yu Province, there was nothing Casualties and economic losses are not large.

Coincidentally, there was flooding in the Huaguo desert, snowfall occurred in Brazil in July, and high temperature occurred in the Arctic.

The Arctic has always given humans the impression of a cold world of ice and snow.However, in recent years, the Arctic has continued to have a "high fever", and glaciers and permafrost have melted rapidly.

Wu Siyuan saw in the future that in December, the temperature in the Arctic town will rise to 12°C. This is indeed the highest temperature ever recorded in the Arctic. In previous years, the temperature measured in the Arctic town was no more than It is 38°C.

This is not good news.

Rising temperatures will cause glaciers to melt.

The melted snow water flows into rivers, lakes, and oceans, which directly changes the local precipitation and ocean currents, causing huge changes in the climate around the world.

Under the ice and snow, there is frozen soil, which will start to melt on a large scale under high temperature.Two-thirds of Russia's land is in permafrost, and many houses, oil and gas pipelines, roads and railways are built in these areas.

When the permafrost melts, the soil will become soft and even form swamps. As the temperature rises year by year, the thawing of the permafrost will become deeper and deeper, and the original infrastructure will be greatly damaged.

But this is not the biggest threat brought by melting glaciers and permafrost. The biggest threat is the remains of ancient organisms and unknown germs that have been frozen for tens of thousands of years.

The extreme high temperature weather in 2016 almost triggered a pandemic of germs.

That year, the temperature in the Arctic region was 6-7°C higher than usual, and the permafrost thawed rapidly.A reindeer carcass was unsealed in this way, and the anthrax bacteria hidden in its body also took the opportunity to regain freedom, quickly polluting the surrounding water and soil.It also killed thousands of reindeer, infected hundreds of people and killed a 1-year-old child.

Russia is even preparing to kill 25 local reindeer to cut off the anthrax epidemic.

……………………………………………………………………………………………………………………………………… ……

Today, extreme weather occurs frequently.

The main reason is climate change.

Climate change has two main features, the first is the increasing average global temperature, and the second is the increase in the rate of climate change.

That means extreme heat and extreme cold are possible.

In terms of rainfall, although the total amount of annual rainfall may not change much, there will be weather conditions with heavier heavy rain and smaller light rain, that is, extreme weather.

With the intensification of climate change in the future, there will be a variety of extreme weather superposition phenomena, such as [high temperature] + [dengue fever], [high temperature] + [drought], etc., [heavy rain], [flood] and [infectious disease] 】It is also easy to happen at the same time.

The main cause of climate change is inseparable from human beings.

With the advancement of science and technology, human beings are becoming more and more capable of transforming nature, and the so-called "uncanny workmanship" of nature is nothing more than that.

But the action of force is reciprocal.

Human beings have more and more influence on nature, and in turn, nature will produce corresponding changes to human activities.
