Chapter 1162 Americans consume too much beef, which is an important cause of climate change...
Chang Haonan was not aware of the far-reaching impact of his paper at this time.
Because in the field of engineering, even the simplest and most straightforward uses require testing and verification, ranging from weeks to years.
And it is difficult for influence to spread beyond this field.
So, if you want to make enough noise before the IPCC meeting, the focus should be on the second half of this paper.
That is the part related to artificial neural networks.
As we all know, if you really want speed in research in the computer field, the development cycle and publication cycle can be frighteningly short.
The reason why websites that pre-publish papers like arXiv can survive and continue to grow is largely because the research iteration speed of these people is even faster than the review speed of regular paper journals. quick.
If you follow the traditional process, it is likely that there will be a lot of disputes about originality.
The article by Chang Haonan and Lissel just provided a huge space for water papers to the majority of emo people in the Internet bubble.
Therefore, all major universities rushed to follow up. Higher-level scholars began to think about how to use similar ideas to expand new fields, while average-level researchers began to fill in the gaps.
In short, regardless of the specific contribution to the development of the industry, at least in terms of the number and popularity of papers, it is not weaker than some established research fields.
It is impossible for anyone to deny the correctness of this improved Levenberg-Marquardt method itself.
And this has achieved Chang Haonan’s original goal...
……
In December 2004, the fourth IPCC assessment was officially launched.
In fact, in principle, the IPCC is closer to an academic conference between countries. It does not conduct any scientific research itself. Like academic journals, it is not responsible for any adopted data itself and only focuses on science. evaluation methods, and provide analysis and suggestions on the premise of "assuming the data is true".
This is of course due to technical feasibility considerations. After all, the United Nations is not a real authority, and it is impossible to go to other people's countries and conduct random investigations.
But it also shows that the conclusions given by the IPCC are not necessarily reliable.
But because it is backed by two platforms, the World Meteorological Organization and the United Nations Environment Program, and everyone still has to eat from the same horse spoon, we still tend to agree with its authority.
But when it comes to the evaluation process, the scene is actually not much different from a quarrel in the vegetable market.
This year, due to a well-known reason, there was more of a smell of gunpowder from the beginning.
Since the number of countries participating in the IPCC assessment is not large, we can only learn from it but cannot copy the order of speeches at the UN General Assembly. Therefore, in the past, just the matter of who came first and who came last was enough for discussion. some time.
But this time, when the U.S. representative proposed to sort them alphabetically by country, no one raised any objection.
Even the Russian representative did not make any statement such as "The initials of your United States is clearly U."
Because under this arrangement, the United States will be next to China.
And everyone wants to see what kind of colorful sparks the two sides will ignite...
According to convention, regardless of the order that follows, Brazil is the first to speak. .
As representatives of South American countries, their core focus is naturally on the changes in tropical rainforests.
“In the past five years, due to extreme climate, deforestation, and natural disasters, the area of the Amazon rainforest has shrunk by approximately 13,000 square kilometers... I would like to remind everyone that the Amazon rainforest Occupying half of the world's rainforest area and one-fifth of the world's total forest area, it has irreplaceable ecological and climate value..."
"Previously, according to meteorological research, in 2005 and 2006, the American continent will suffer from a severe drought that has not been seen in a century. The entire region is already on the edge of desertification. Once the critical point is exceeded, the rainforest will irreversibly begin to die, and then the It will have a catastrophic impact on the global climate and even destroy the entire world..."
"..."
The Brazilian representative started with an obviously alarmist content.
It’s okay to deceive the brainless so-called “climate activists” with these arguments, but none of you here who is not a thousand-year-old fox cannot be deceived by these rhetorics that you have been accustomed to hearing for a long time.
The Amazon rainforest is indeed very important, but few people have mentioned that while the forest area is decreasing, it will also expand spontaneously, and the annual net area reduction cannot reach the equilibrium critical point at all. As few people have mentioned, while "one species is destroyed on average every hour", new species are also appearing at about the same rate.
What everyone is really concerned about is whether there is any hidden purpose behind this passage...
“I said Lao Ding, their statement obviously adopted the statement issued by the U.S. Environmental Protection Agency some time ago. Disaster data... Could it be that they want to cooperate with the United States to target us? "
Zheng Guogang, the deputy director of the China Meteorological Administration who was accompanying him, approached Ding Zhongli's ear and asked in a low voice.
The latter lowered his head and thought for a moment, but still shook his head:
"Judging from past experience, most third world countries are on the same front as us in the IPCC, but South America is greatly influenced by the United States after all, and the representatives speaking on the stage may not really represent Brazil. I’m on my own, so I really can’t say..."
However, just when people here were already a little worried, the Brazilian guy on the stage suddenly changed the subject:
" The Amazon rainforest is a precious wealth for all mankind, and the protection of the rainforest is by no means the task of South American countries themselves, but should be shared by the international community..."
At this time, everyone in the Chinese delegation relaxed. He breathed a sigh of relief——
The other party obviously did not have any political purpose, he just used this as an excuse to ask for money.
Sure enough, the Brazilian representative quickly realized that he hoped that the World Bank and developed countries could provide the country with corresponding quotas of environmental protection funds according to the proportion of tropical rainforest area...
Although this routine looks a bit It's rough, but in the context of environmental protection, it really can't be completely rejected.
After all, asking for money is quite simple in the IPCC.
There are also some countries that hope to use the banner of environmental protection to achieve more unspeakable goals...
For example, the American representative who came to power later.
Just as everyone expected from the beginning.
After reviewing the global climate change data in the past five years as usual, he directly pointed the finger at China based on the speech made by the Brazilian representative:
“In the past five years, Behind China's rapid economic development are rapidly deteriorating environmental problems. Calculated in terms of total pollutant emissions, China has become the world's largest polluter..."
"We have noticed that in order to further improve its paper According to the above economic growth data, China is already developing the grassland area in the northeastern part of its territory, which may lead to severe soil erosion and desertification, and its impact on global climate balance is no less than the damage suffered by the Amazon rainforest. Here are Satellite photos taken last year and this year clearly show that the total area of vegetation has been significantly reduced..."
"China is the worst in terms of the bad results caused by destroying the environment. Countries around the world should work together to stop this. Destructive behavior…”
"..."
The U.S. representative was obviously premeditated. Not only did he present quite detailed survey data, he also spent almost one-third of his speech criticizing China's development behavior in eastern Mongolia. , the intention is obvious.
In the past, the Chinese delegation’s strategy was basically to defend and refute the accusations made by the other party point by point.
Although it is organized, no matter how reasonable your explanation is, you will always be at a disadvantage in terms of momentum.
But this time, Zheng Guogang, who was about to speak, had no psychological fluctuations.
I even wanted to laugh a little bit.
After the American representative left, he strode onto the stage almost impatiently.
Of course, as a decent person, it is impossible to have a scolding attitude when you first come up.
But like the previous two, I first reported on the basic environment and climate conditions of the country and Northeast Asia.
After completing all the routine content, he slowly turned around and faced the US delegation who still didn't know what was about to happen.
“Here, I would like to remind everyone that our country’s development in eastern Mongolia Province is itself part of a large environmental protection plan. These are aerial photos of the same place and location before and after development, which are much more detailed than satellite images. , it is enough to see that these lands are already in a state of desertification, but it is our development behavior that has improved the overall vegetation level..."
"..."
The previous part, follow Past explanations seemed little different.
But immediately afterwards, Zheng Guogang suddenly changed his tone:
“On the contrary, we have sufficient evidence to prove that climate change and natural disasters just mentioned by the Brazilian representative have a great impact. Part of the reason is that Americans consume too much beef..."
