The military-industrial scientific research system of the academic master.

At this time, Chang Haonan was still unaware of the far-reaching impact of his paper.

Because in the engineering field, even the simplest and most direct uses can take anywhere from a few weeks to a few years to test and verify.

And the influence is difficult to spread beyond this field.

Therefore, if one wants to create a big enough stir 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 research in the computer field really wants to be fast, the R&D cycle and publication cycle can be incredibly short.

The reason why pre-publication websites 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.

If the traditional process is followed, there will likely be a lot of disputes about originality.

The article by Chang Haonan and Lissel just happened to provide a huge space for writing water papers for the vast number of emo computer scientists who were in the Internet bubble.

Therefore, all major universities rushed to follow suit, and scholars with higher levels began to think about how to use similar ideas to expand new fields, while researchers of average level began to fill in the gaps.

In short, regardless of its specific contribution to the development of the industry, at least in terms of the number of papers and popularity, it is no less than some old research fields.

It is impossible for anyone to deny the correctness of this improved Levenberg-Marquardt method itself.

And this has already achieved Chang Haonan's original purpose...

……

In December 2004, the IPCC's fourth assessment officially began.

In fact, in principle, the IPCC is closer to an academic conference between countries. It does not conduct any scientific research itself, and like academic journals, it is not responsible for any of the data it adopts. It only focuses on scientific evaluation methods and provides analysis and recommendations on the premise of "assuming the data is true."

This is of course out of considerations of technical feasibility. After all, the United Nations is not a real authority and it is impossible for it to go to other countries and conduct random investigations.

But it also shows that the conclusions given by the IPCC are not necessarily reliable.

It's just that because it is backed by the World Meteorological Organization and the United Nations Environment Programme, and everyone still has to eat from the same spoon, so they tend to recognize its authority.

But when it came to the evaluation process, the scene was actually not much different from a quarrel in the vegetable market.

This year, due to some well-known reasons, there was a lot more tension from the very beginning.

Since the number of countries participating in the IPCC assessment is not large, they can only refer to but not copy the order of speeches of the UN General Assembly. Therefore, in the past, the issue of who will speak first and who will speak later would be enough to discuss for a while.

But this time, when the US representative proposed to sort by country letters, no one raised any objection.

Even the Russian representative did not make any statement such as "The first letter of your country's name, the United States, is clearly U."

Because under this arrangement, the United States will be next to China.

Everyone wants to see what kind of colorful sparks will be torn between the two sides...

As per convention, Brazil will be the first to speak, regardless of the subsequent order.

As representatives of South American countries, their core focus is naturally on the changes in the tropical rainforest.

"In the past five years, due to extreme weather, deforestation, and natural disasters, the area of ​​the Amazon rainforest has shrunk by about 1.3 square kilometers... I would like to remind you that the Amazon rainforest occupies half of the world's rainforest area and one-fifth of the world's total forest area, and has irreplaceable ecological and climate value..."

"Previously, according to meteorological research, in 2005 and 2006, the American continent will experience a severe drought that has not been seen in a century. The situation in the entire region is already on the verge of desertification. Once the critical point is exceeded, the rainforest will begin to die irreversibly, which will have a catastrophic impact on the global climate and even destroy the entire world..."

"..."

The Brazilian representative started off with a statement that was clearly alarmist.

These claims may be able to fool those brainless so-called "climate activists", but everyone here is a seasoned fox and it is impossible for them to be fooled by these statements that they have been accustomed to hearing for a long time.

The Amazon rainforest is indeed important, but few people mention that while the forest area is decreasing, it will also expand spontaneously, and the annual net reduction in area does not reach the critical balance point at all.

As rarely mentioned, while "on average one species is destroyed every hour," new species are appearing at about the same rate.

What everyone really cares about is whether there is any purpose hidden behind this statement...

"I say, Old Ding, their statement clearly believed the disaster data released by the U.S. Environmental Protection Agency some time ago... Could it be that they want to cooperate with the Americans to target us?"

Zheng Guogang, deputy director of the China Meteorological Bureau who was accompanying him, leaned close to 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:

“From past experience, most third world countries are on the same side 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 the Brazilians themselves, so it’s hard for me to say…”

However, just when people were getting a little worried, the Brazilian guy on the stage suddenly changed the subject:

“The Amazon rainforest is a precious treasure of mankind, and rainforest protection is by no means the responsibility of South American countries alone, but should be undertaken by the international community…”

At this point, everyone in the Chinese delegation breathed a sigh of relief.

The other party obviously has no political purpose and is simply using this as an excuse to ask for money.

As expected, the Brazilian representative soon revealed his true intentions, hoping that the World Bank and developed countries would provide the country with a corresponding quota of environmental protection funds based on the proportion of tropical rainforest area it owns...

Although this approach may seem a bit crude, it is impossible to completely reject it in the context of environmental protection.

After all, asking for money is considered quite simple in the IPCC.

Some countries, however, hope to achieve even more unspeakable goals by waving the banner of environmental protection...

For example, the American representative who came to power later.

Just as everyone expected from the beginning.

After reviewing the global climate change data for the past five years as usual, he pointed the finger directly at China based on the Brazilian representative's speech:

"In the past five years, behind China's rapid economic development are rapidly deteriorating environmental problems. Calculated by the total amount of pollutant emissions, China has become the world's largest polluter..."

"We have noticed that in order to further improve its economic growth data on paper, China has begun to develop the grassland area in the northeast of its territory. This may lead to serious soil erosion and desertification, and the impact on the global climate balance is no less than the damage suffered by the Amazon rainforest. Here are satellite photos taken last year and this year, which clearly show that the total vegetation area has decreased significantly..."

"China is the worst country in terms of environmental damage. All countries in the world should work together to stop such destructive behavior..."

"..."

The US representative clearly had this planned in advance. Not only did he produce quite detailed survey data, he also used almost one-third of his speaking time to specifically criticize China's development activities in the eastern part of Mongolia. His intentions were obvious.

In the past, the strategy of the Chinese delegation was basically to defend and refute the other party's accusations one by one.

Although it is well-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, showed no psychological fluctuations.

Even a little to laugh.

After the American representatives left, he strode onto the stage almost impatiently.

Of course, as a respectable person, it is impossible to start off with a swearing attitude.

Instead, like the previous two speakers, he first reported on the basic conditions of the environment and climate in the whole country and Northeast Asia.

After completing all the routine tasks, he slowly turned around and faced the American delegation who had no idea what was about to happen.

"Here, I would like to remind you that the development carried out by our country in the eastern part of Meng Province is itself part of a large environmental protection plan. This is an aerial photo of the same place and location before and after the development. Compared with the satellite photo, it is much more detailed, enough to see that these lands were already in a state of desertification. On the contrary, our development behavior has improved the overall vegetation level..."

"..."

The previous part seems to be no different from past explanations.

But immediately afterwards, Zheng Guogang suddenly changed his tone:

"On the contrary, we have ample evidence to prove that the climate change and natural disasters mentioned by the Brazilian representative just now are largely due to the fact that Americans consume too much beef..."
