"For Russia, global warming is a good thing"
This is a flower grower's article titled "Flames Under the Ice, Can't Be Extinguished!" Siberian Super Wildfire is the largest in the world! The Arctic has become a new circulation" article after the comment, describing that the fires in Siberia have exceeded the scale of fires in Greece, Turkey, Italy, the United States and Canada combined, and russia is very Buddhist for fire fighting, because many remote areas of the fire can not be extinguished at all.
When the majority of netizens are still for the Siberian fire when the heartache, the netizen's message is like a bright light, instantly the building to be crooked, since the ancient second floor out of the talent, I have to say that the netizens brain hole looks very reasonable, global warming, the north becomes warmer, Russia will usher in an unprecedented opportunity for development in the future, there is also a theory that after the warming of China's north will also be likely to return to the warm and humid Tang Dynasty West Week, then global warming for China, is it good or bad?
<h1 class="pgc-h-arrow-right" data-track="4" > the northern rain is really increasing, and the claim in the myth is true</h1>
A popular post in 2019, but in 2021 it is hot again, interested can move to the following link to read:
https://www.toutiao.com/w/a1706039364015112/
The article describes an astonishing fact that climatic tipping points have emerged, since the mid-2010s, precipitation in northern China is increasing, crossing the Qinghai-Tibet Plateau, pouring rain in Xinjiang, precipitation crossing the Qinling Mountains, vegetation restoration in the Yellow River Basin of the Loop is increasing at an alarming rate, and China will usher in the Tang and even Western Zhou eras with the best continental climate!
This perspective believes that everyone should see for the first time, because the sea level has risen after global warming, China's southeast coast will be soaked in water, and Jiangsu will be the first to suffer due to the extremely low altitude, followed by the Bohai Bay and the Beibu Bay coast and the Pearl River Delta region.
The southeast coast of China after sea level rises over meters
It has never been thought that in the future the north will likely open a new door, compared with the little area of flooding on the southeast coast, how vast the north of China is, if this day really comes, China's rise is like a divine help, the world will once again return to the era of land power.
Precipitation in the north is really increasing
Flower growers were also pointless when they first saw this post, because we all know that China has embarked on an unprecedented Three-North Shelterbelt program since the late 1970s, which includes afforestation in the Yellow River Basin, and the clearing of the Yellow River is also the result of afforestation on the Loess Plateau.
However, a data from the Xinjiang Climate Center shows that rain in Xinjiang is really increasing, since 1961, Xinjiang's annual precipitation has increased by an average of 10 mm per 10 years, and precipitation has shown an increasing trend in all four seasons, and since 1961, the average annual temperature in Xinjiang has also risen at a rate of 0.3 °C per 10 years, higher than the national (0.24 °C per 10 years) change level in the same period.
Xinjiang's climate is changing to warm and humid, but what about Inner Mongolia? In a December 2, 2020 report on "This is how the Mu wusu sandy land turns green," Xinhua said that "from 2000 to 2019, the local precipitation in the Mu Wusu Desert increased by an average of 5.7 mm per year."
Pan Hongxing, a first-level researcher at the Department of Desertification Control of the State Forestry and Grassland Administration, also said that "in the past 20 years, the rainfall in the main sand and dust source areas in northern China has increased by an average of about 20%. In recent years, the temperature in northwest China has been high and the amount of precipitation has increased, which is conducive to the restoration of vegetation. ”
Data from authoritative departments show that the temperature in the northwest region is high, and the increase in precipitation has become a trend! There are four warm and humid periods in Chinese history, namely the Xia, Shang and Western Zhou, the Two Han Dynasties, the Tang Dynasty, and the Ming Dynasty, which are also the most powerful dynasties in Chinese history.
Therefore, there seems to be nothing wrong with the summary of the future climate change in the Divine Thesis to return to the Sheng Tang And Western Zhou, of course, the prologue to the rise of the Chinese nation is gradually opening, and we are witnessing the rise!!
<h1 class="pgc-h-arrow-right" data-track="5" > global warming is good or bad for China, or the Northern Hemisphere? </h1>
Northwest turn warm and wet, which is a good thing, still need to be doubted? Of course, the problem of climate is a matter of the whole body, because in the early Triassic period of geological history, there was an era of transition from an arid continental climate to a warm and humid oceanic climate, and the result was the extinction of animals adapted to the relatively arid permian, and the dinosaurs occupied the whole world.
Of course, we don't need to compare global warming in geological history, events of this scale span millions or even tens of millions of years, in our view, "ten thousand years is too long, we only fight for the day", so what will change in the current trend of change in the north?
Climate change is mainly the change of light, heat, water, the change of these factors is bound to affect the growth of crops, warming will increase the frost-free period, that is, plant growth time increases, rain increases the irrigation requirements are reduced, is a good thing!
However, there is no free lunch in the world, and it will also have a serious impact on the main cash crops in Xinjiang, such as increasing temperature will cause cotton diseases and insect pests, more violent sandstorms will lead to a decline in pollination efficiency, reduce production or even harvest, have a significant impact on grapes, dates, watermelons, melons and other cash crops, short-term will reduce production, and even change the structure of cash crops in the medium and long term.
The other is the increase in rain, followed by extreme climates, such as blizzards, torrential rains, and the caused floods and extreme heat, and the increase in strong convective weather, such as Sha Yidong in Korla City, Xinjiang, who suffered heavy losses in the hail of strong convective weather on April 17, 2015, and large pieces of fragrant pears were only left with branches.
Chen Yaning, director of the State Key Laboratory of Desert and Oasis Ecology at the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences, said that the current increase in precipitation in Xinjiang cannot change the current situation of arid deserts, and because the uneven distribution will cause catastrophic events, water resources and ecological pressures will continue to exist, and it is not blindly optimistic.
As early as the beginning of the twenty-first century, Academician Shi Yafeng of the Cold and Arid Areas Environmental and Engineering Research Institute of the Chinese Academy of Sciences put forward the judgment of the transformation of the climate in the northwest region from "warm dry" to "warm and wet", and the current mainstream view is that the temperature rises, resulting in an increase in land evaporation, resulting in an acceleration of the water cycle and an increase in precipitation.
Another important reason is the increase in glacial meltwater, the increase in river runoff, and the expansion of oasis area, but this consumes glaciers, and one day glaciers will disappear, and the future may face more arid climates and greater threats to desertification!
Increasing extreme weather: every year will witness history
I believe you have found a fact, this year's rainstorm is particularly severe, at every turn is the yellow warning of heavy rain, a few hours of heavy rainfall can make the whole city have serious water, many friends are scolding where so much budget is used every year, why are the drainage facilities so bad?
But you should be wrong to blame the drainage facilities, such as the news released by the Zhejiang weather on August 13, the rainfall in Xiaoshan District from 5 to 8 o'clock reached 145 mm, and the highest one-hour rainfall was 85.8 mm, which was completely enough to meet the level of the black rainstorm of the Hong Kong Observatory, and the drainage facilities of a city could not withstand the precipitation of such a short-term rainstorm or even exceptionally heavy rainstorms, and waterlogging was likely to occur.
From August 11 to 12, 2021, extreme heavy rainfall occurred in Liulin Town, Sui county, Suizhou City, Hubei Province, from 21:00 on the 11th to 9:00 on the 12th, the cumulative rainfall in Liulin Town was 503 mm, and the rainfall from 4:00 to 7:00 on the 12th reached 373.7 mm, and this round of heavy rainfall caused more than 8,000 people in Liulin Town to be affected, 21 people died, 4 people lost contact, and the power and communication in the township were interrupted.
From August 4 to 5, 2021, Sichuan rainstorms, earlier is Shaanxi, Shaanxi, Gansu and Shandong and Jiangsu, as well as the southern Guangdong Fujian torrential rain, from the end of July Henan rare rainstorms, less than a month in China's many places of heavy rain frequent, and one is a heavy rainstorm or even exceptionally heavy rainstorms, every time you see such news is very heart-wrenching!
The heavy rainstorm that occurred in 2021 is so large, the area is wide, and the impact is serious, you should have seen it! This is the greeting gift of global warming to everyone, and what is followed, the IPCC has made an assessment of the occurrence of the earth's catastrophic climate caused by the various stages of global warming in its August 9 report:
1, 50 years of high temperature events will be from the past 2% (really once in 50 years) to 78.4%, almost 2 years three times, how to live this day, it is estimated to be well planned.
2, extreme precipitation events from once in 10 years to once every 3 years, but you must have an illusion, this year the world's heavy rains have fallen to China?
3, the IPCC goal is to control the global temperature rise within 1.5 °C, because the extreme weather after reaching 2 °C may be unbearable for human beings, but even if we follow the target set in the Paris Agreement, then it will reach 1.5 °C around 2040, even if the temperature is controlled and no longer rises, then the sea level will continue to rise...
Warm and humid, just our wishful thinking, accompanied by countless extreme weather events, in addition to China's extreme precipitation events, the global catastrophic high temperature is emerging in an endless stream, such as Moscow, the western United States and Canada and southern Europe extreme heat "hot dome event", the last 10 years have occurred six times, 3 times in 2021.
There is also the Siberian wildfire event in 2021, this year's wildfire season is far from over, but the scale has already exceeded 2020, and we really can't predict what the future will be.
Extended reading: The thawing of the tundra, the nightmare of the Northern Hemisphere
We don't talk about methane emitted in the tundra, although some scientists have said that the methane released on the Siberian tundra after the 2020 wildfire season can even be described as a "methane bomb", only from the melting of the tundra to briefly explain.
The tundra belt is mainly distributed in the northern hemisphere, the tundra not only locks a lot of carbon, but also provides support for infrastructure, so Russia, Alaska in the United States and Canada have a large number of infrastructure directly built in the tundra belt, so the tundra melts, the infrastructure in these areas will slowly collapse, according to incomplete statistics, Russia's infrastructure in these areas is worth more than one trillion US dollars!
Another thing that must be reminded is that in addition to the permafrost belt in the northern and southern hemispheres, China's Qinghai-Tibet Plateau is the third region with a permafrost belt, so global warming, the thawing of the permafrost, we will also face the crisis of permafrost ablation.
Global warming brings us some opportunities, but more are challenges and crises!
